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.
European Roller
The European roller gets its name from the spectacular rolling and tumbling aerial displays performed by males during courtship. It is the only roller species in Europe and one of the continent's most colorful birds. Declining across much of its western range due to agricultural intensification and habitat loss.
