NEARCTIC
Madrean Pine-Oak Woodland

The cooler Pine-Oak forests and woodlands of Mexico's inland mountains offers a nice change from the lowland deciduous jungles of the coast and the arid scrub of the valleys. Even though this habitat is physically not too far from Neotropical rainforest and Neotropical tropical woodland, I have placed it into the Nearctic biogeographical region due to the taxonomic affinities of it's plant and animal species. 

There are many striking (New World) Warblers moving back and forth seasonally from the Nearctic to the Neotropics, so Mexico is obviously a thoroughfare for these colourful migrants. Below is the 'Crescent-chested Warbler', a species that enjoys Oaks.
