It's a phenomenon that grabs your attention during the winter - massive flocks of crows at dusk. And your brain starts cycling through all kinds of questions as you watch...why are there so many of them? What are they doing? Why this spot?
So, let's help each other answer some of these questions and come up with new ones to explore. Here's how to start:
Streaming: this is best described as a line of crows all coming from one direction and heading in one direction. Please share location and direction the crows are coming from or going to. For help on counting moving birds: http://bit.ly/counting201_eBird
Staging: these are groups of crows gathering prior to sunset. Typically, crows will stage in one area and then at dusk (after the sun sets) as it gets dark, they will move to a final roosting spot for the night. We are interested in learning more about staging sites including how dispersed they may be in a given area and the number of crows at each staging site. Please share location and number.

Roosting: This is the final place crows gather as the night sky darkens. This is typically where they will stay for the night. We are interested in where preferred roosting sites are located, how many roosting sites crows may have in a given town/city/rural landscape, and how many crows are roosting together.
