Helmeted Hornbill

 The Helmeted Hornbill() is a member of the Bucerotidae. It is believed to be one of the largest living hornbills.

This species has mainly black plumage, but its belly is white. Its tail, which is white and has a black band, is two-thirds the length of the entire bird. It should be especially noted for its helmet-like casque, which reaches on the upper bill from the bill's base to the tip of the beak.

Due to habitat loss and hunting for its casque, which is valued in some places more than ivory, the helmeted hornbill is classified as Critically endangered. 

Brown Booby

 The Brown Booby(Sula leucogaster) is the most widespread member of the booby family. It resides throughout the tropical oceans, and it breeds on specific coasts and islands in there.

Its body color varies from black to dark brown, and it has a white underbelly. The male species has a blue orbital ring, while the female has a yellow one. Unlike most other booby species, the plumage of a juvenile is very similar to that of an adult. Interestingly, the brown booby incorporates marine debris as nesting material.
