Which of the following islands is known for its extensive birdlife, especially the red-footed booby?

Little Cayman is renowned for its extensive birdlife, particularly the red-footed booby. This small island is home to a significant breeding colony of these seabirds, which are characterized by their striking red feet and distinctive appearance. The environment of Little Cayman, with its lush vegetation, clifftops, and coastal areas, provides ideal nesting and feeding grounds for the red-footed booby and various other bird species.

In addition to the red-footed booby, Little Cayman has a diverse ecosystem that is attractive to birdwatchers and wildlife enthusiasts. The island's commitment to conservation ensures that these habitats are preserved, enhancing opportunities for observing these fascinating birds in their natural setting.

The other islands, while having their own unique features and attractions, do not have the same level of recognition for extensive birdlife or specific concentrations of species like the red-footed booby as seen on Little Cayman. Grand Cayman, being the largest of the three islands, is more developed and urbanized, which affects its natural habitats. Cayman Brac also has some birdlife but is not specifically known for the red-footed booby to the extent that Little Cayman is. Macau is unrelated to the Cayman Islands and does not pertain to this context of birdlife.
