Biologists Find Evidence of Migration Gene in Birds

Millions of migratory birds occupy seasonally favorable breeding grounds in the Arctic, but scientists know little about the formation, maintenance and future of the migration routes of Arctic birds and the genetic determinants of migratory distance. In new research, a multinational team of researchers established a continental-scale migration system that used satellite tracking to follow […]

Mass die-off of birds in south-western US ’caused by starvation’

Mass die-off of birds in south-western US ’caused by starvation’

The mass die-off of thousands of songbirds in south-western US was caused by long-term starvation, made worse by unseasonably cold weather probably linked to the climate crisis, scientists have said. Flycatchers, swallows and warblers were among the migratory birds “falling out of the sky” in September, with carcasses found in New Mexico, Colorado, Texas, Arizona […]

Philadelphia Sees Largest Mass Collision Event in the City in 70 Years

Philadelphia Sees Largest Mass Bird Collision Event in the City in 70 Years

In a single day, more than 1,000 migrating birds collided with buildings within a small area in downtown Philadelphia, killing a particularly large number of Parula, Magnolia, Black-and-white, and Black-throated Blue Warblers, Common Yellowthroats, and Ovenbirds as well as smaller numbers of many other species. Birds collide with many types of buildings on a regular […]
