Hispaniolan crossbill

It was formerly regarded as conspecific with the Two-barred Crossbill , from which it is now assumed it evolved.

The Hispaniolan crossbill is classified as Endangered (EN), considered to be facing a very high risk of extinction in the wild.

Hispaniolan Crossbill is befuddling: the authors write of “this crossbill” as “a species typical of northern coniferous forests,” and note that it was “considered part of the White-winged Crossbill species complex” until 2003. It would have been more accurate, and thus necessarily less confusing, to write that the Hispaniolan Crossbill was long considered conspecific with the White-winged Crossbill, but was recognized as a separate species in 2003. The front of the book is rather less satisfying. More

differences, the Hispaniolan Crossbill (Loxia megaplaga) is now considered a separate species from the White-winged (L. leucoptera). Future revisions of this account will reflect this change. In North America, White-winged Crossbills (L. l. leucoptera) occupy boreal coniferous forests from Alaska to Newfoundland and south into the Washington Cascades, the central Rocky Mountains, and the northeastern states. Other races of this species breed in the Palearctic from northern Scandinavia to Siberia (L. l. bifasciata), and in the mountains of Hispaniola (L. l. megaplaga). More

The Hispaniolan Crossbill (Loxia megaplaga) is a crossbill that is endemic to the island of Hispaniola in the Caribbean and therefore only found in Haiti and the Dominican Republic. It was formerly regarded as conspecific with the Two-barred Crossbill (L. leucoptera), from which it is now assumed it evolved. There is general acceptance that the origin of the L. megaplaga can be traced to southern populations of L. leucoptera. More

years ago, Hispaniolan Crossbills were stranded in the coolest areas in the Caribbean-the high mountains on Hispaniola. Because of its restricted range, small population size, and increasing threats to pine forest, this species is listed as Endangered by the IUCN (International Union for Conservation of Nature and Natural Resources; BirdLife International 2008). * Identification Recommended Citation Hart, Julie A. 2010 .Hispaniolan Crossbill (Loxia megaplaga), Neotropical Birds Online (T.

Emerald, Hispaniolan Crossbill, Antillean Siskin and Golden Swallow. We also visit the Visitor Centre that has recently been built within the Sierra de Bahoruco. The centre is situated overlooking a beautiful valley called Hoyo del Pelempito–the view is nothing short of breathtaking! In the afternoon, on our way back to Pedernales, we stop at a location near Laguna Oviedo for Antillean Piculet. Night in Pedernales. More
