Locating specific plant species

Overall I was quite nervous about this process due to the fact I didn't think I was very sufficient at finding plants. Primarily since I had not done it before in this context. My plan to find all these different plants worked pretty well, actually better than anticipated. I started off at home on iNaturalist and looking up the different plants to get an idea on if anyone has located them in the immediate area close to my home or CUI. CUI was my best bet so I simply started at the Heritage Garden working along the ridge line up towards the chapel. It funny to me because I was able to find California Brittlebush, California Sagebrush, and California Buckwheat all within about 50 yards of each other. It was funny due to that I hadn't even reached the spot I expected to find them. Deerweed was very difficult for me to find and I cannot say for sure I even found it. I was basing my search area on a post on iNaturalist near CUI. I had to go off trail multiple times in the same area making circles looking for the trademark yellow. I had to start looking even closer at the plants though for leaf characteristics and the stem types to try and distinguish. Once you really look in detail at each plant you start to see the identifying characteristics between the similar ones. Even the other plants I wasnt looking for made it difficult to search.

iNat User agonzalo Photographs the Birth of a Sloth in Panama - Obseration of the Week, 2/16/20

iNat user @agonzalo photographed a Brown-throated Three-toed Sloth giving birth in Panama, and it’s our Observation of the Week!

“The story of the picture of the sloth giving birth is based on applying a basic equation,” explains Aitor Gonzalo. “perseverance plus extreme LUCK!

I didn't see the full delivery. I heard a loud screech that caught my attention and managed to see the sloth at a distance of about 150 meters. Through the camera I could see that the mother was manipulating the newborn but at the moment everything was very confusing for me. In the photos you can understand better what was happening.

While his primary interest is birds, Aitor says “I never miss the chance to photograph sloths, monkeys, and other animals, alone or in company with their babies. Obviously, a birth in nature is to win the lottery.”

Famously slow-moving, three-toed sloths eat leaves and digest them at a sarlacc-like rate, sometimes taking 2 weeks to digest a meal! Sleeping in trees for about 16 hours a day, they make their way to the forest floor only once every 7-8 days in order to defecate, and as you can see they even give birth up in the treetops. Newborn sloths, like the one in Aitor’s photos, gestated for about seven months. It will spend the next five months or so clinging to its mother before it starts to climb on its own in earnest.

Aitor has always been interested in nature, but he credits his two daughters, Milena and Costanza, for his current “real real true passion for nature (I mean me as an already old guy and eager to go out and spend most day taking photographs).” One daughter has a PhD (earned in France) and studies soil microbes, while the other is studying Environmental Policy Analysis and Planning at UC-Davis in California. “Both of my daughters…

are passionate about nature, the environment, and its conservation and have discussed it with so much enthusiasm that it is extremely difficult not to get engaged. Moreover, both have been vegetarians for many years, and to challenge them and myself, I became vegan.

A regular iNat and eBird user, Aitor (above, with @ruthpierson and @claryliz) finds iNaturalist to be “an essential tool. It has everything. It helps you identify animals, it keeps records of everything, you can get statistics, it is interactive and user friendly. Besides, it is fun and challenging.”

In my front yard

I took advantage of the partially sunny (ok dryish) day to take a walk around my yard. I wanted to see if there were any new specimens fruiting. I was surprise to see so many changes from just a month ago. My daffodils are in full bloom, the maple trees are budding, and my comfrey is sprouting.

As I walked along the hardwood pile of logs, I noticed a new fruiting of the polypores and ran inside to grab my camera. On one log I found 3 different species growing and just up the hill two more. I am curious about the succession of the species that will inhabit these logs.

I found Trametes versicolor, Stereum hirsutum, a Daedalea, Schytzophyllum commune, and the beautiful violet colored Tricaptum abietinus.

In my backyard, in a particularly wet and shady spot I found a Coprinus-like specimen, but it was growing out of a wood stump. The spore print was black and prolific. As I sit here typing this that specimen has completely turned black and the gills have almost disintegrated.

The theme today, seems to be the velvet or hairy type mushrooms. I was excited to discover some new things and am proud of myself for being able to tell the difference between the shelf-like zoned specimens. At first glance they all look so similar, but when you stop and really look, you can see all of the subtle differences.

Make observations from your LFW property "private"

Good Morning,

Thank you for taking the time to test out our Land for Wildlife (LFW) Logan project by adding observations to it from your LFW property. So far it is looking like it will be really useful for us and hopefully yourselves.

After having a look at the observations as they come in it seems to work better on our end if observations are made "private" rather than "obscured". When we view all observations on the map view, we're only able to see the location of the private observations while the obscure observations remain obscured and we are only able to see the exact location once we click on each individual observation.

So with the observations that you upload to this project if you could please make them "private" rather than "obscured" that would be really appreciated.

If you have any questions, please let me know.

Field Journal #1: ID and Flight Physiology

On Sunday, February 9th at 3:00pm, I went out into the woods next to the Burlington Country Club in search of birds. The weather was partly cloud at about 35 degrees with little wind. The sun at this time was shinning. I walked around these woods for about 30-45 minutes and did not see or hear any birds. I had noticed earlier that there were many birds outside my dorm (Wing), so I walked behind the dorm where there are trees and into the condo complex and there I found American Robins, European Starlings, a Black-capped Chickadee, and a Hairy Woodpecker. I was surprised that none of these birds were in the more quiet, wooded area that I was previously in. But, I found the Robins foraging for food on the ground, and the other birds fly from tree to tree and these particular trees were more spaced out which could be why the birds preferred them.
The most abundant species I observed was the American Robin. I observed around 20 individuals in the area and I found it interesting that they all mostly moved as a group. I watched 7 individuals fly from an understory tree, up to the top branches of what looked to be a birch tree. Watching them fly, it seemed like their flight pattern was made of rapid wing flaps, and just a second of gliding before flapping again. These birds also did not stay in one place for a long time, and quickly moved from tree to tree. Compared to the Black-capped Chickadee I observed, their flight patterns differed greatly. For starters, I only observed one Chickadee, which is very different than the horde of Robins I saw. Next, the Chickadee had significantly smaller wings just because it was a smaller bird, so what I observed was 1 or 2 flaps, then gliding, then flapping again. The Chickadee flew in a wave-type formations with dips and rises while the Robins flight was much more direct.
Wing style and flight style are obviously connected because it is how a bird fly’s, but more than this, it determines how and where species can survive. Species with large wings and more of a gliding flight pattern would have trouble getting into smaller spaces while they would excel with large expanse traveling. Alternatively, species with smaller wings and a more rapid flight pattern would be better at getting into smaller spaces and would have trouble traveling long distances. I observed a group of European Starlings flying, and although they don’t have huge wings, they’re bigger then a Hairy Woodpeckers. These Starlings were almost exclusively on the tops of tree because they do not have small, dexterous wings. Comparatively, I watched a Hairy Woodpecker fly onto a branch and start pecking, which took a lot of small wing flaps to land there and stay on the tree. The starlings did not have to do these small flaps because they were only landing on treetops, which do not require much precision.

A Difficult Search for Birds

I was only able to find four birds: Black-capped Chickadee, American Crow, a female House Sparrow and a female Downy Woodpecker. I was able to identify a female from a male Downy Woodpecker because the top of the head was black and the male would be black with red.

Along main street, I identified an American Crow. I first noticed the bird taking off and landing on the electrical wires above me. From below, I observed the tail of the bird was triangular shaped, rather than the Common Raven’s diamond-shaped tail. The wingbeats of the American Crow were also more frequent, while a raven would soar more. The wings of the American Crow are elliptical which are used for short bursts of high speed, a fast take off, and tight maneuvering. The first observation I made was the wingbeats of the American Crow were longer compared to the Downy Woodpecker’s short, quick wingbeats.

Then, I spent more time comparing the features of the Downy Woodpecker and the American Crow. For the Downy Woodpecker, the wing flap resembles fluttering and the bird was tucking in its wings against its body. Flying between the fruiting and pine tree, the woodpecker glided down in the air, flapped upwards approximately 3 times, and repeated to glide then flap, which created a wavy-like pattern. This pattern is used almost exclusively by woodpeckers to minimize profile drag, which we learned in one of the lectures. The woodpeckers flight pattern is unique, so it can be easily identified when compared to another bird’s flight pattern like an American Crow.

The habitat niche for a Downy Woodpecker and an American Crow can be similar. You can spot both birds in woods, parks and many other residential areas. The crow tends to thrive around people more than the woodpecker. Unlike the crow, the woodpecker can nest in cavities within a tree in deciduous woodlands.

The habitat influenced bird distribution because I was in an urban area with less habitat for the birds. I did try to go to parts of campus like Redstone, the UVM green and by the green near central campus where there would be more habitat then compared to developed areas around academic buildings. There would have been a larger distribution if I went into the woods where there was more habitat for birds.

I went birding in the morning (9:14am-10:44am) as I thought the birds would be more active then. For the weather, there were clear skies, not a lot of wind, rain or snowfall. There was a blizzard two days before on Friday, February 7th making Burlington very cold (approximately -4 degrees) and covered in snow.

Later in the week, I happened to visit Trinity Campus where I saw approximately 100 crows roosting around sunset. The gathering was near the woods and they either landed in the trees or were flying around calling one another. I noticed there was more habitat nearby than the urban areas on campus. I could go more often around sunset if I wanted to spot more crows roosting and potentially other birds in the area.

I found walking in areas with less habitat, more human disturbances, and during colder weather will not result in many birds. I would have better luck going in the woods during the same time of day, but when the weather is warmer and there is less snow outside.

Bird Walk 2/16/2020

We began at the trail head to Centennial Woods at 11:05 on 2/16/2020. We immediately observed a red-tailed hawk in a tree across the street from the small pond on Catamount Drive. It rested in the tree for about a minute, then with a couple flaps of its wings, it moved to another branch on the tree. At this point, the bright red of its tail was apparent. After about another minute, it flew off. Its wing movements were relatively slow and graceful compared to smaller birds, as one wing beat moved a considerable amount of air.
Not very far into the woods we heard a high-pitched whistle call, followed by the sight of a female northern cardinal on a nearby bush. Soon a male alighted on a branch near her. After about a minute, they both flew off to another tree. They had a somewhat undulating flight pattern and did not fly a far distance. Farther in the woods we stopped walking in the middle of the marsh as a mixed flock of black-capped chickadees and tufted titmouses entered the area. The chickadees darted among the tops of the trees, using their wings only to hop short distances between branches. After a little while of staying still, the chickadees began to sing as the entire group slowly moved on.
On the way out of the woods, we observed an American crow flying fast over the woods. Its wings moved in fast, rhythmic rowing motions as it sped through the air. As we left the woods, we noticed a large flock of European starlings calling and flying between trees. The starlings had swooping flight patterns and long periods of gliding with out-stretched wings. At times, their gliding would be broken up with a burst of rapid wing beats or a single flap. Like the chickadees, members of the flock were constantly moving between trees and branches, but their flight patterns were quite different. The starlings often moved great distances between their two perches, while the chickadees did not. The chickadees barely ever glided, and seemed to use their wings only to facilitate their hops.

Les punaises du genre Buenoa
Les Notonectidés les plus intéressants appartiennent au Buenoa . Ce genre se reconnaît par une longueur inférieure à 8 mm, la forme étroite du corps et les yeux énormes occupant presque tout le dessus de la tête.
De 2016 à 2018, trois espèces ont été récoltées.
Buenoa confusa
C’est la plus petite. J’ai eu la chance de la trouver dans six localités de la province depuis 1995 dont à Saint-Félix-de-Valois.
Selon ma base de données, cette punaise a été capturée dans les régions adminstratives suivantes au Québec : Lanaudière, Laurentides, Montérégie et Outaouais.
Buenoa macrotibialis
À une occasion à Longueuil
L’insecte est rare et ma base de données indiquent sa présence dans le Bas-Saint-Laurent, en Montérégie et en Outaouais au Québec.
Buenoa margaritacea
La plus grande du genre dans la province. 4 spécimens cueillis dans deux étangs à Longueuil.
Selon ma base de données, c’est aussi une espèce rare dans la province : Bas-Saint-Laurent, Ile-de-Montréal et Montérégie

Étang du Capricorne à Longueuil
Le fait le plus intéresant de ces trois punaises est de les avoir ramassées en 2016 dans un étang de Longueuil : Étang du Capricorne.
Ce dernier a subi une transformation par eutrophisation. Lors de ma premières visites en 2005, il y avait des épinoches. En 2009, les épinoches ont disparues. En 2016, l’étang était couvert de Lenticules mineures.
Ce sont seulement dans les zones sans Lenticules mineures de l’étang que ces punaises avec des nymphes étaient présentes.

White Wagtail in Austin 2020-02-09

On Saturday, 2/8/2020, Janet Davis and Jeff Osborne found a White Wagtail on the Colorado river in Roy Guerrero Park in southeast Austin. This species had never been found in Texas before, and as the word got out to the birding community, birders raced to the location to try and see the wagtail for themselves.

I was able to chase this bird late Saturday afternoon 2/9/2020. Almost as exciting as seeing the bird was experiencing the camaraderie of fellow birders also trying to see it. Figuring out where to park was easy: an area along the trail was full of cars with a few people standing around with binoculars, cameras, and tripods. They told me the bird was being seen from a spot about a mile down the trail, so I set off at a fast pace in the direction they indicated. It was a little after 4 PM on a wet and unseasonably warm overcast day. Luckily rain had subsided for the afternoon.

As I walked I met a couple people on their way back who reassured me I was on the right path. A little before 4:30 I found the group watching the bird. I smiled and took a couple iPhone photos:

Group watching White Wagtail

Group watching White Wagtail

I joined them and within 3 or 4 minutes I was seeing a White Wagtail in my spotting scope. A lifer without having to leave Austin! To me, the bird looked like and acted like a big fancy American Pipit, bobbing its longer black and white tail as it walked around on a rocky island in the riverbed. Indeed, this species is related to our local pipits and two were foraging with it on the rocks. It was so far away and blended in with the rocks so well that finding the bird was difficult. We were constantly helping each other locate it via describing land marks. And those with spotting scopes shared them often.

A tall, lean, heavily bearded young man called me by name and introduced himself as Christian Walker, a fellow central Texas birder I hadn't seen since he was a teenager. Now he was in his late 20s! After watching the bird and enjoying the group of birders for about 30 minutes I started preparing to leave when Austin-area birder Wendy Harte showed up. I started trying to find the wagtail for her when Christian almost casually mentioned it had left with the two pipits. We first thought he was joking but Christian was the only one alert enough to observe the wagtail and two pipits fly off downriver. He even heard their flight call notes. I started the walk back to my car, and Christian and Wendy went off to try and find the wagtail again.

Because of the long distance to the bird and poor light that day, my photos were terrible. The best turned out to be this digiscoped photo taken with my iPhone through my spotting scope:

White Wagtail - 1 - 2

You can at least see its black bib.

Attached is my iNaturalist observation with a couple more equally poor photos, and my eBird list is here.

Here are a few more photos on Flickr.

Bird Walk #1 - St Joseph's College of Maine

I went on the cross country trail of St Joseph's College of Maine, all the way down to the waterfront of Lake Sebago. It was about 10 degrees outside and there was quite a bit of snow on the ground. I was able to spot Black-capped Chickadees and the American Crow, while the other birds I was only able to hear. I went around 11 am, so perhaps this, along with the harsh temperatures, was not ideal to spot many birds.
In terms of flight patterns, the contrast between the Black-capped Chickadees and the American Crow was quite apparent. The Black-capped Chickadees have more elliptical wings. They only appeared to fly short distances into small shrubs and trees, not needing to obtain high speeds or altitudes. In comparison, the American Crow appears to have more slotted, high lift wings. This made sense because they tended to fly higher in the air and glided for longer periods of time, searching for prey below. The chickadees also appeared to have to flap their wings more while the crow simply adjusted its' wings to glide easily.

Top 10 des observations botaniques en Haute Savoie sur iNaturalist

Plus de 2000 observations de plantes (validées NR : niveau recherche), correspondant à 650 espèces (règnes Plantae et Fungi) ont été enregistrées à ce jour sur l’application iNaturalist pour le seul département de la Haute-Savoie.

Voici les 10 espèces les plus photographiées et validées :

1. Épilobe à feuilles étroites, Chamaenerion angustifolium
2. Gentiane jaune, Gentiana lutea
3. Silène enflé, Silene vulgaris
4. Grande astrance, Astrantia major
5. Anémone des Alpes, Pulsatilla alpina
6. Rhododendron ferrugineux, Rhododendron ferrugineum
7. Hellébore fétide, Helleborus foetidus
8. Primevere commune, Primula vulgaris
9. Capillaire des murailles, Asplenium trichomanes
10. Gentiane pourpre, Gentiana purpurea

À titre de comparaison, le projet Flore 74 démarré en janvier 2020 donne le classement suivant, où l’on reconnaîtra, outre l’influence saisonnière des mois d’hiver, des biais personnels.

1. Polypore marginé, Fomitopsis pinicola
2. Hellébore fétide, Helleborus foetidus
3. Houx, Ilex aquifolium
4. Cladonie poudrière, Cladonia coniocraea
5. Polypore versicolore, Trametes versicolor

Burnt area protocol: keep it clean!

With the project taking off and more and more people making observations, it's a great time to remind everyone about preventing the spread of weeds and plant diseases.

@patrick_campbell has a great message to share, originally from Kerri-Lee Harris, for anyone contributing photos to the project:

"Avoid spreading weed seeds, diseases and fungi. Before walking into burned areas, think about where your shoes have been. They could be carrying seeds or soil-borne fungi … including Phytophthora! This fungus is deadly for many native plants and it is easily spread. Make a habit of spraying your shoes and other equipment with methylated spirits before entering or leaving fragile, regenerating bushland. And don’t forget your car. If you have driven along muddy tracks, wash your vehicle before heading off into another forested area."

Yuen Long Park15/12/2020

A very special day! Yuen Long Park is full of thrushes and today not only grey backed, Japanese or blackbird! An eye browed thrushes appeared, which was a scarce winter visitor and my first time to meet it. How wonderful! It jumped at the slope and found some worms. Another good birds are Chinese grosbeak and white shouldered starling. They are common winter visitor in HK but uncommon at urban area. Mor and more new thrushes were found in YL park in recent years. We need to go more YL park and discover more.

A Couple of Cold Mornings

Sunday, February 9th 9:35 am
Weather: Clear sky and 3° F
Location: urban university campus

The idea was, because of the chill, no forest birds would be foolish enough to come out, so I focused on walking around the urban green spaces of the university, hoping more plump urban birds would be out. There was one.

On the university green, the Downy Woodpecker was identified by sight on a fruiting tree. The female appeared to be foraging, as she continued to peck at the bark of the tree. She, at first, did not offer any effort at flying but spent more time pecking at the tree and turning away from the lens. Small flights between trees was the best I was going to receive but then, done with the batch of trees or tired of amateur photographers, the Downy Woodpecker flew.

The flight of the woodpecker was different than expected. The first thing noticed was the pattern of flapping followed by the wing tucking in for a few seconds. There seemed to be slightly, just a few seconds, more of flapping than tucking. After the flight, the observation of the flight path was made. As the woodpecker flew, the path was horizontally curved as the bird fell in latitude when the wings were tucked and increased when flapping the wings. The reason was not found until in class when Professor Strong noted this was done to minimize profile drag.

It should also be noted a Black-capped Chickadee was heard at the university green. However, the bird simply mocked me as I walked around in circles in the green with my eyes towards the sky and trees. No chickadee was found.

End: 10:39


Saturday, February 15th 8:11
Weather: Clear sky and -2°F
Location: Start in urban campus transition to Trinity woods

After the less than successful walk around the green, I decided to attempt to search for birds among the trees on Trinity campus.

The birds gave me hope as, just a few feet away from my dorm, I heard a flock of Black-capped Chickadees and White-breasted Nuthatches calling. I saw them fluttering from tree to tree and to the buildings. I stuck to the stand of trees, where most of them were roosting, but the combination of tiny songbird and long needles made picture taking exceedingly difficult. Thankfully, one Black-capped Chickadee was nice enough to grace me with a short flight.

The flight was more linear than the woodpecker. The cause was likely because of the almost continual flapping of the wings. There were periods where the wings were tucked for an extra second. However, the Black-capped Chickadee’s destination was below their starting point so I assume the extra second was to let gravity take over.

Deeper into the woods, there was nothing to be spotted. An American Crow, Black-capped Chickadee, and American Robin were heard but none were seen. Again, no picture or slight of flight.

End: 8:52, cut slight short as I was freezing


Ending remarks
Seeing as the results from the urban and forest walk were similar, I believe my walks were sparse in bird numbers because of the temperature or time. However, walking to organic chemistry at 8:30 in the morning, I have seen American Robins, American Crows, Black-capped Chickadees all roosting near Trinity woods, so I heavily suspect it was the temperature. I assume the birds were smart enough to stay home, unlike me. Next walk, I will either plan on a warmer evening or morning.

Not part of the walks, I found a couple dozen crows roosting on trees, cawing and clacking their bills. As many of them were flying from tree to tree, there were many times to observe flight. The crows' flight was still linear like the Black-capped Chickadee, but there was more gliding mixed in with the flapping. I believe the American Crows were able to glide because of their larger wings which appear to have a higher aspect ratio than the Black-capped Chickadee.

To conclude, a bird’s flight seems like a good way to at least narrow down the species which the bird can belong to. The curved flight path of the woodpecker appears to be distinct and could be seen at a distance. The amount of time spent flapping, gliding, or tucking the wings could also be recorded and later compared to narrow down the options. While the flight of the bird may not be unique enough to narrow down to the exact bird, it is a good method for formulating an educated guess of species or type of bird.

Feds burn island weeds at Mono Lake to help birds feather their nests.

LEE VINING, Calif. — A massive weed infestation on a tiny island at Mono Lake has choked out the nesting grounds that California gulls need to complete a life cycle as ancient as the million-year-old Sierra Nevada ecosystem.

Observation of the Month: Fox squirrel.

For a long time, the only squirrels found at Mission Trails Regional Park were California ground squirrels (Otospermophilus beecheyi). But in 2016, an iNaturalist user photographed a fox squirrel (Sciurus niger) on a trail west of Kumeyaay Lake. No one reported another fox squirrel in the park on iNat until April 2019 and since then, seven more observations have been posted, including one by skylukr ( This new population of non-native critters seems to be confined to an urban border of the park, just east of Kwaay Paay Peak Trail (off of Father Junipero Serra Trail).

Identyfikacja Formica spp! Ważne!

Jeśli sfotografujemy i dodamy obserwacje odnośnie Serviformica, należy w notatce przy obserwacji zapisać, czy chodzi o grupę fusca/lemani, czy rufibarbis/clara, czy rufibarbis/clara/cunicularia. F. cunicularia możemy czasem odróżnić - chętniej zasiedlają miasta, są ciemniejsze i mają często jedno wyjście, ale gdyby nie było pewności, należy wpisać całą grupę. Oczywiście jeśli obserwacja jest z Podlasia, czy Łodzi i dotyczy fusca/lemani to możemy śmiało zaznaczać fusca, gdyż lemani jest gatunkiem górskim, zaś fusca żyje zarówno razem ze swoją kuzynką, jak i na niżu.
Kopcówki oczywiście jako podrodzaj Formica, wyjątkiem może być F. truncorum i ewentualnie pratensis...

Wildflower season is here!

Once again, we are going to have have an excellent display of spring wildflowers! As you explore the park and take photos of the colorful blooms that you see, please post your sightings to iNaturalist. (Thank you to those of you who have already started!)

By doing so, you will help in documenting the variety of species being seen in the Usery Mountain Recreation Area this year, along with where and when. This helps others know which areas of the park are currently putting on a show! This data is also extremely valuable in long-term monitoring efforts to determine if drought, wildfires, and changes to climate conditions have an affect on the survival and life cycle timing of plant species in the area.
