As a follow up to our last post answering “where did all the birds go?”, many people don’t realize that there are already a lot of birds on their southern migration. Yellow Warblers are a perfect example of this as many that nested in Maine have already begun their journey back toward the Amazon lowlands in South America. Thanks to the participation of citizen scientists using eBird.org and the folks at BirdCast interpreting their submission, we can craft a really cool visual of when our birds leave.
Below are two charts showing the frequency, or percentage of total checklists reporting a species, for the Northeast and Southeast:
As you can see, the number of Yellow Warblers being reported in the northeast has quickly decreased as they more into the southeastern US. Keep an eye out though! They will be slow to leave completely as the stragglers can last into the end of October in Maine: Bird Observations Chart: Yellow Warbler >>
