保护状况
This woodpecker is critically endangered. It has a single tiny, declining population which is threatened by habitat loss of mature forest due to logging, dam construction, agriculture, military and golf course developments. A major problem now is that one of their main habitats is being destroyed. The current population is estimated at less than 600. This species is suspected to be declining at a rate of 10-19% over ten years, as a result of ongoing clearance of old-growth forests.<p>This woodpecker is legally protected in Japan. It occurs in Yonaha-dake Prefecture Protection Area and small protected areas on Mount Ibu and Mount Nishime and conservation organisations have purchased sites where it occurs, but it is mainly found in the Okinawa Prefecture. In 1996, Yambaru was designated as a national park.<p>The habitat of the Okinawa woodpecker is threatened by the construction of six new American helipads located about 9.5 km Southwest of the Yanbaru forest of Takae. The lives of the birds themselves are also put at risk by the flights of V-22 Ospreys over the island.

Red-headed Fody
Foudia eminentissima
A sparrow-like weaver. Red-hooded breeding males are distinctive, but females and non-breeding males are drab. A Comoros endemic that is found in and adjacent to humid forest on the western three islands, and in drier, scrubby lowland habitats on Mayotte. Plumage varies across the different islands. The most distinctive birds, on Grand Comoro, have much less red on the breast than other populations. Can be very similar to Red Fody. Breeding male Red-headed Fody lacks red on the back and belly, though molting male Red Fody can match this pattern. Females and non-breeding males very similar to Red Fody, but Red-headed Fody is larger, darker, and more greenish, with a longer, slightly curved bill. Also similar to female House Sparrow, but distinguished by the more olive-green coloration and the longer bill. Calls are high, silvery notes, given in long series as a song.
Cozumel Wren
Troglodytes beani
Small brownish wren found only on Cozumel. Rather plain overall, with dark barring on the wings and tail. Lacks white eyebrow. Generally more arboreal than mainland “House Wrens”, occurring in dense brushy woodland throughout the island. Often perches conspicuously when singing, but otherwise fairly secretive. Listen for loud song of chatters and clearer trills, as well as harsh scolding calls.
Red-footed Booby
Sula sula
Large seabird of offshore tropical waters around the globe; not seen from the mainland. Adult plumage is variable, but all have bright red feet and colorful bill and face; some have wholly brown plumage, others are white with a black trailing edge to the wings; the tail can be black or white. Immatures of all types are brown overall with dull pinkish feet. Looks smaller and more slender than other boobies, with more crooked wings. Nests on offshore islands (usually in trees and bushes, unlike other boobies, which nest on the ground).
