Jamaican Poorwill Siphonorhisamericana

This species has not been recorded since 1860, and it may have been driven to extinction by introduced mongooses and rats, whose effect may have been exacerbated by habitat destruction. However, it cannot yet be presumed to be Extinct because there have been recent unconfirmed reports, and surveys may possibly have overlooked this nocturnal species. J.; Christie, D.

Barcelona, Spain and Cambridge UK: Lynx Edicions and wholesale cheap nfl jerseys BirdLife International.24 Small, long tailed nightjar. Overall mottled dark brown, narrow white chin patch, reddish brown hindneck, spotted black and white. Long tail (extending well beyond primaries), tipped white in male and narrowly buff in female. Similar spp. Antillean Nighthawk Chordeiles gundlachii is larger with conspicuous white band in wing, flies high with conspicuous call and, when perched, primaries reach tail tip. Chuck will’s widow Caprimulgus carolinensis is even larger and reddish brown, with proportionally shorter tail (extends slightly beyond primaries). Reference has been made to five specimens, but only four have been located (C. in litt. 1994, 1999). Two specimens (one untraced) were taken in the Great Salt Pond area near Spanishtown in 1857, with others collected in the Bluefields area, near Savanna la Mar in western Jamaica, (apparently) at Freeman’s Hall near Albert Town and from near Linstead (BirdLife Jamaica in litt. 1998, C. in litt. 1994, 1999). Three of these localities (excepting Freeman’s Hall) are in the lowlands on the southern side of the island, and there is anecdotal evidence that the species could often be found in (what is now assumed to be) the Hellshire Hills (BirdLife Jamaica in litt. 1998, Cleere cheap authentic jerseys and Nurney 1998, Raffaele et al. 1998, C. in litt. 1994, 1999). However, the specimen information is confused by the practice of labelling skins with the residence of the collector as the location of collection (C. in litt. 1994, 1999). The mongoose was introduced in 1872 (after the last confirmed record), but it can be assumed that rats were the cause of any decline prior to this date. As its ecological requirements are not known, the impact of habitat destruction is difficult to assess. However, the loss of at least 75% of original forest, with remaining forest largely secondary, presumably had (and perhaps continues to have) an adverse effect.Conservation Actions UnderwayNone is known.
