Burlington iNaturalists,

Thank you for contributing to our phenology clock thus far! We have collectively spotted 28 of the 45 species (62%) that were chosen to be part of our clock. The newest version of our clock will continue to be posted on the Burlington Wildways website found here:

Most recently, red trillium flowers, large white trillium flowers, ostrich fern fiddleheads, ruby-crowned kinglets, and mourning cloak butterflies have been sighted and added to this year's clock. More observations of chipmunks, Canadian geese, phoebes, titmice singing, box elder bugs, and red-winged blackbirds continue to roll in.

For the end of May, continue to look for and submit observations for some of the more ephemeral species that won't last until summer like the trillium flowers and the kinglets. Also look for new arrivals such as basswood flowers, white pine pollen, and the fluff from cottonwoods which usually appear around this time. Keep an eye out as well for rarer species that haven't been found yet this year in Burlington including ospreys and muskrats.
