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.
Great Tit
The great tit is the largest European tit and one of the most studied wild birds in the world. Research at Wytham Woods in Oxford has monitored great tit populations since the 1940s, contributing enormously to ecology and evolution. These innovative birds famously learned to open milk bottle tops in 20th-century Britain.
