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.
Đại bàng đuôi trắng
The white-tailed eagle is Europe's largest eagle and the fourth-largest eagle in the world. Once extinct in Britain, it has been successfully reintroduced to Scotland and Ireland through conservation programs. These powerful raptors can live over 25 years and form lifelong pair bonds.
