American Tree Sparrow
Here’s a look at a little bit of lingering green, thanks to some holly trees, with a lovely American Tree Sparrow (Spizelloides arborea). This cute bird is one of many on the move to the south right now. We are far enough into the season that these winter residents, along with species like the White-throated Sparrow and Dark-eyed Junco, are beginning to fill up our yards. Be careful not to confuse their rufous caps with the similar Chipping Sparrow. Scott Kruitbosch Conservation & Outreach Coordinator

October is a terrific month to spot some falcons flying by in migration, and like with our winter friends the Snowy Owls, sometimes a pole is the best place to look! If you’re lucky enough you might be able to get an American Kestrel, a Peregrine Falcon, and a Merlin like this all on one day. I would suggest waiting and watching because seeing them soar back into the sky is worth it. Scott Kruitbosch Conservation & Outreach Coordinator

If you look closely, you will notice a metal band on the leg of this young Ruby-throated Hummingbird. It serves to identify unique individuals of these tiny birds and allows biologists to track their migration path. Ruby-throated Hummingbirds breed in the eastern USA during the summer, but they spend the winter in lower Central America. This bird was banded on an RTPI project in western Costa Rica and returned to the same site a year later, after it had made another successful trip to North America – a journey of at least 4,000 miles. Impressive for a bird that weighs not much more than a...
Read MoreAmerican Redstart Changing into Fall Plumage
Many of our migratory birds are on their second or third brood for the season already and slowly are starting to prepare for their journey south. Most flashy warblers molt out of their brightly colored breeding plumage in the next few weeks and will start migration once all flight feathers are grown in to the point that they can safely sustain their long journey. Although we have not quite reached Roger Tory Peterson’s notorious “Confusing Fall Warblers” level of alternate plumage yet, the first signs are here. Even though this male American Redstart still displays its characteristic black...
Read MoreBay-breasted Warblers
We are getting to the end of the spring migration season, and as hard as that is to believe our later arriving species are trickling through as many of the species that arrived earlier are getting down to nesting. One of my favorite passing migrants is the Bay-breasted Warbler (Setophaga castanea), a large and gorgeous species that I believe seems more rare than it is. Bay-breasted Warblers start passing through the region as most of the other spring birds are peaking. These birds remain mostly high in the canopy – above eye-level and out of sight behind recently emerged leaves, and...
