Bejeweled Journeyer

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...

American Redstart Changing into Fall Plumage

American 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...

WILD AMERICAN SKIES

It was a young Roger Tory Peterson’s close encounter with a Northern Flicker right here in Jamestown which ignited his love for birds. The wild birds of North America were at the heart of his passion for nature and were the impetus for the actions he took to preserve our living world. Venerated for embodying freedom, grace, and beauty in flight, birds inspire a deeper connection with nature and evoke a fascination with exceeding the limits of our earthbound human existence. This summer there are many opportunities to meet and be inspired by these wonderful animals in Chautauqua County. Roger...

Remarkable Recapture

Golden-winged Warblers are among the most imperiled birds in North America. Their numbers have plummeted nearly 70% in the past 50 years, and this species continues to decline at a staggering 2.5% each year. Outside of their core breeding range in the upper Great Lakes Region (mostly Minnesota and Wisconsin) they have just about disappeared altogether, and several northeastern states now no longer have viable populations of Golden-winged Warblers around. What causes these declines? Well, a number of factors play a role here. Golden-winged Warblers prefer to live in open, wet areas that are...

Bay-breasted Warblers

Bay-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...
