Our latest Bird of the Week is an iconic symbol of spring in eastern North America. The males' brilliant blue plumage with russet and white highlights makes them easy to spot when they perch in the open, scanning for insect prey, which they can see from over 60 feet away.

QUIZ ANSWER. Warblers can be tough, but a few key features can help with identification. With warblers the key features to look at often include the face, breast, flanks, and undertail pattern.

Barn Swallows occur on every continent (except Antarctica), but South America has always been a wintering ground for them... until the 1980s, when a few of them decided to stay over and breed in Argentina. Since then, that breeding population has grown and now has switched around its migratory schedule 180 degrees. Fascinating research from the College of Agriculture and Life Sciences at...

The African Collared-Dove or Ringed Turtle-Dove (a form of the African Collared-Dove) is very rarely seen as a wild bird in...
