WOOD-WARBLERS OVERWINTERING IN THE CENTRAL VALLEY
By "wood-warblers" I mean members of the Wood-warbler Subfamily, the Parulinae, of the newly enlarged Emberizid Family, the Emberizidae. By "Central Valley" I'm referring to the hot, arid valley or depression slicing all the way through the Chiapas Highlands, the place where I find myself now.
At http://www.backyardnature.net/chiapas/birds-cd.htm these migrant warblers are listed as likely to be found overwintering in the valley:
Of the above species I've spotted about half. Yet other warbler species occur here permanently, or only when they migrate between wintering grounds farther south than Chiapas, to breeding grounds farther north.
I'm mentioning these warblers mainly to whet your appetite. Migration will soon begin so this is a good time start reviewing field marks and birdsong recordings.
