Flatcrested

Flatcrested is a term used in ornithology to describe a type of bird species that has a crest on its head which is not raised or erect. The crest is typically flat or slightly curved, and it may be used for display purposes or to attract mates. This feature is often seen in species of birds that are known for their elaborate courtship displays, such as some species of parrots and cockatoos.

The flatcrested trait is not exclusive to any particular family of birds, and it can be found in a variety of species across different orders. For example, the flatcrested cockatoo (Lophochroa leadbeateri) is a species of cockatoo found in Australia, while the flatcrested parakeet (Psittacula krameri) is a species of parakeet found in Southeast Asia.

The flatcrested trait is thought to have evolved as a result of sexual selection, with males competing for mates by displaying their crests. In some species, the crest may also serve a functional purpose, such as protecting the bird's eyes or helping it to forage for food.

Overall, the flatcrested trait is an interesting example of how birds have evolved to meet the challenges of their environments and to compete for mates.
