Ebird – has recently animated their extensive bird sightings database to show an incredible algae bloom of bird migration.
Watch the Northern cardinal’s near steady presence in the Eastern, Lower 48. While the Bobolink, who journeys from as far away as Argentina makes it’s summer home in New England. Compare these two species with the Blackpoll warbler who only passes through New England en route to the barren taiga of Northern Canada to breed. As the Blackpoll warbler comes from further away it arrives in the second half of May. Compare this to the Palm Warbler, who migrates from the Caribbean and Florida and arrives in New England weeks before the Blackpoll as early as mid-April.
New England is also home to winter residents. Watch the inverted migration of the White throated sparrow that leaves the cozy confines of New England and the southern Appalachians in April for a summer breeding in Canada, only to return come September for the winter.
