About These Birds
Budgerigar
The budgerigar is the third most popular pet in the world after dogs and cats, and by far the most common pet parrot. Wild budgies travel in enormous nomadic flocks that can darken the sky. Males can learn to mimic human speech, with one record-holding budgie having a vocabulary of 1,728 words.
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.
