Catbird's Syrinx
Catbird's use different tones and notes in their songs to communicate their presence, lay claim to their territory, and attract mates.
Are catbirds friendly to humans?
Gray catbirds are shy by nature but will acclimate to people if given some encouragement.
Why are catbirds so aggressive?
That means the males not only have to compete for mates. But they find a good area to nest in, and then protect their nest until their babies grow. Being aggressive is a way for their young to survive. Gray catbirds are also known to destroy the eggs of other birds such as Sparrows and robins.
