Carduelis notata

The black-headed siskin (Spinus notatus), also known as the Jonny Bee,[ citation needed ] is a species of finch in the family Fringillidae. It is found in Mexico, Belize, El Salvador, Guatemala, Honduras, and Nicaragua. Its natural habitats are subtropical or tropical moist montane forest and heavily degraded former forest.

Evolution and systematics

Recent work suggests the species radiation happened much later, within the last 1 million years, and posits the radiation happened due to climate change in the late Pleistocene. The changing climate could have fragmented various habitats in the Andes, initiating allopatric speciation. [2]

The Paraguana xeric scrub (NT1313) is an ecoregion in Venezuela to the north and east of Lake Maracaibo and along the coast of Aruba, Bonaire, and Curaçao. The region holds flora and fauna adapted to the very dry conditions of the coastal dunes and inland areas of bush, scrub, briars and cacti. There are several endangered species of animals and birds. Efforts at protecting the environment have been ineffective. Most of the original trees have been cut down, dunes are being destabilized by loss of vegetation, scrub is replaced by farmland and vegetation is destroyed by grazing goats.
