About These Birds
Blue Jay
The blue jay is a bold, intelligent member of the corvid family known for its striking plumage and loud calls. Blue jays are important dispersers of oak trees, as they cache thousands of acorns each autumn. Their complex social behavior includes mimicking the calls of hawks to scare other birds from feeders.
Common Nightingale
The common nightingale is celebrated as one of the finest songsters in the bird world, inspiring poets from Homer to Keats. Males sing complex phrases of over 250 different types, often at night during breeding season. Despite its famous song, the nightingale is a plain-looking bird that skulks in dense vegetation.
