- Mimus saturninus
The Chalk-browed Mockingbird, as well as many other Mockingbirds, is famous for its huge repertoire of songs and calls, including many imitations of other birds, hence the name Mockingbird.
Identification
This mockingbird has pale overall colour, with brown wings and tail. A brown stripe crosses its eyes as well. The bird has a chalk (clearer) eyebrow and the white tip on the end of its tail is easily noticed when in flight. Colour variations can happen due to local soils. The Chalk-browed Mockingbird can be easily mistaken with its congener Tropical Mockingbird (Mimus triurus). They are very similar in appearance and their ranges meet in some coastal locations, which is where the Tropical is found.
Diet
Its diet consist basically of fruits and invertebrates, especially insects. Since the seeds are not digested, this mockingbird may help in the dispersal of some plants, e.g. orange and avocado.
Behaviour
This bird is commonly found in flocks of up to 13 individuals. While walking on the ground or perched in branches, it often opens and closes its wings partially and rapidly. The reason of such behavious is still unknown.
