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...

Yellow-headed Blackbird

Here is a bird you do not see too often around these parts – the Yellow-headed Blackbird! This immature male, found a few weeks ago by Stefan Martin, should ordinarily not be farther east than Illinois or Wisconsin. However, it took a wrong turn during migration and ended up all the way on the Atlantic Coast with us at Stratford Point, CT. He has been hanging out with Common Grackles, Red-winged Blackbirds, and Brown-headed Cowbirds while feeding on seed we put out plus whatever insects it can find. The bird has started singing, too, perching on various trees, snags, wires, and shrubs...

Fox Sparrow

Any time we see snowfall from mid-March on, we might notice an increase in the number and species diversity of birds at our backyard feeders. Those who pay close attention might also have the opportunity to view more elusive birds – those that would otherwise just be passing through or returning to the area relatively unnoticed – that are driven out of their preferred habitats by the extreme conditions in search of food. One such bird that can seem to appear out of nowhere is the Fox Sparrow (Passerella iliaca). These large sparrows really enjoy scratching at the ground with both...

Golden-winged Warbler

Golden-winged Warbler

Without a doubt, one of the highlights of our recent work in Costa Rica was the recapture of this Golden-winged Warbler, which was banded last year in the same area it was caught this year, near Rara Avis Rainforest Lodge. Since we last saw it in March of 2016, it undoubtedly traveled back to its breeding grounds somewhere in North America and hopefully managed to find a mate of its own species. Golden-winged Warblers are suffering from dramatic declines throughout their range, and are increasingly hybridizing with closely-related Blue-winged Warblers. As a result, this species is at serious...
