Curaçao is a Lesser Antilles island in the southern Caribbean Sea and the Dutch Caribbean region, about 65 km (40 mi) north of the Venezuelan coast.
The island consists of a basaltic center of volcanic origin, rimmed in the coastal zones by marine limestone terraces. The landscape is rugged and rocky with prominent cliffs. Christoffelberg, at the northwest end of the island, is the highest point of the island. Curaçao possesses several semi-enclosed inland bays, which are densely fringed by mangroves. There are also several enclosed shallow, hyper-saline lagoons that are important for waterbirds, as are the numerous man-made freshwater catchment dams, some of which retain significant amounts of fresh water well into the dry season. The island is surrounded by coral reefs and variety of rocky, sandy or rubble shores.
Curaçao has the largest human population of the Leeward Netherlands Antilles, and about 30% of the island has been occupied by housing and industry.
Of the 215 species of birds that have been recorded from Curaçao only 57 are resident (current or former) breeding species, the vast majority being migrants, winterers, and occasional vagrants.
As with Aruba and Bonaire, due to the proximity of the islands to the mainland of South America and the general mobility of birds, there are no island endemic bird species. Nevertheless, the islands have been sufficiently separated from other sources of interbreeding such that at least 16 subspecies have been described from Aruba, Bonaire, and Curaçao. Eleven of these species breed on Curaçao, and two are totally restricted to teh island, namely the Brown-throated Parakeet and the Barn Owl. A subspecies of Grasshopper Sparrow (Ammodramus savannarum caribaeus) found only on Curaçao and Bonaire appears vocally distinct from other North American and Caribbean forms.
Curaçao's bird life is rather unique, with species of West Indian origin mixed with those of South American origin. This is demonstrated by the presence of a Northern South America biome-restricted bird, the Bare-eyed Pigeon as well as a number of more wide ranging South American spescies.
Curaçao is globally important for its nesting terns (Common Tern and Least Tern) and for the Near Threatened Caribbean Coot.
The relatively large size of Curaçao, the wide variety of habitats, and the more pristine and diverse state of its vegetation compared to the smaller and still more pastoral neighboring islands of Aruba and Bonaire, mean that Curaçao provides some of the best opportunities for protecting native bird diversity in the Leeward Netherlands Antilles.
Willemstad is the capital of the island and it is a charming port and one of the Caribbean’s few UNESCO World Heritage cities. Vivid, sherbet-colored buildings showcase Dutch colonial architecture that can't be found anywhere else outside of the Netherlands.
With its delightful Dutch colonial architecture, bustling commercial capital and excellent history museums, Curaçao feels like a little piece of Europe on the edge of the Caribbean. That is, a little piece of Europe with glorious hidden beaches, amazing onshore snorkeling and diving, and a wild undeveloped windward coast.
