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:
- Yellow-rumped Warbler
- Magnolia Warbler
- Yellow Warbler
- Black-throated Green Warbler
- Common Yellowthroat
- Worm-eating Warbler
- Yellow-breasted Chat
- Black-and-white Warbler
- Kentucky Warbler
- MacGillivray's Warbler
|
- Northern Parula
- Ovenbird
- Louisiana Waterthrush
- Northern Waterthrush
- American Redstart
- Orange-crowned Warbler
- Tennessee Warbler
- Nashville Warbler
- Wilson's Warbler
|
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. |
