One morning in early autumn, I was running errands in downtown Keene, New Hampshire, when I was stopped in my tracks by a flash of yellow. Crouching down, I found a gorgeous, palm-sized bird, olive above, with a belly as gold as sunshine. It was a species I’d never seen before, and it was lying dead on the ground beneath a store window.
After consulting several field guides and two friends who know the intricacies of warbler identification far better than I ever will, I deduced that it was a mourning warbler – a secretive songbird of boreal and high-elevation forest clearings, with a migration route that tracks to Central and South America. Imagine flying all that way – a wonder of beauty and color – only to be felled by a run-in with a pane of glass. [Read more…] about The Perils of Bird Migration

The departure of ruby-throated hummingbirds, Baltimore orioles, migratory woodpeckers, and numerous warblers doesn’t leave us entirely without striking birds, however.
The grackle appeared early last spring, the day before I put the feeder away (so as not to tempt the bears who would soon be awakening from their winter dens). In the dim light of a cloudy day, this avian visitor seemed at first to be just another blackbird, on the larger side, perhaps, and with a longer than usual tail. When I peered at him through the binoculars, however, his head and neck shimmered with iridescent blues and purples, and there seemed to be a greenish tinge to his wings. 
In the spring and summer of 2021, the public reported many deaths in young songbirds — common grackles, American robins, blue jays, and other species — in the mid-Atlantic states.
New research on the glittering White-necked Jacobin hummingbird reveals nearly 20% of the species’ adult females have male-like plumage.
Worldwide, the cost of bird collisions with planes has been estimated at $1.2 billion per year. But information on bird movements throughout the year can help avoid damage to aircraft and risk to passengers.
