In addition, climate change is projected to stress the region's unique biodiversity by causing a northward shift of forest and transition to near-desert in the driest areas of the LRGV
. Many wildlife species, like the ocelot, have the potential to migrate as habitats shift, but a lack of suitable core habitat and connecting corridors will limit their success.
Today, I continue to listen in these ways for the Mexican American of the LRGV
continues to struggle with being heard and seen.
Monk and Brush (2007) found that bronzed cowbirds responded to playback of Audubon's oriole (Icterus graduacauda) song, which was used in oriole surveys in the western LRGV
. Monk and Brush (2007) suggested additional studies, using playback songs of additional species, to further study this apparent nest-locating behavior.
The field study was conducted from 20 Mar to 23 May 2009 on the Research Farm of the Texas A&M AgriLife Research & Extension Center at Weslaco, located in the LRGV
, south Texas, USA (N 26[degrees] 09' 27" W 95[degrees] 57' 47").
As of 1990, more breeding white-winged doves occurred outside the LRGV
than within it (George et al.

Carlton confirmed identifications by examination of male genitalia and com parison to published illustrations with vouchers from LRGV
populations (Agnew et al.
It is estimated that less than 5% of the habitat that originally covered the LRGV
still remains (Purdy 1983; Jahrsdoerfer & Leslie 1988).
* 530 bird species, some reaching their northern limit in the LRGV
and not found elsewhere in the U.S., making this a critical protected habitat and a much-sought-after destination for visitors and bird enthusiasts from around the world.
Historically, White-winged Doves in the LRGV
have relied heavily on anacua (Ehretia anacua), Texas ebony (Pithecellobium flexicaule), Mexican ash (Fraximus berlandieriana), and, to some extent mesquite (Prosopis glandulosa), as well as citrus for nesting (Cottam & Trefethen 1968, Schwertner et al.
-- The LRGV
comprises the southernmost four counties of Texas (Cameron, Hidalgo, Starr and Willacy counties).
Migratory birds also rely on the LRGV
during their long trips north and south, and these, combined with the rare birds native to the region, make it one of the favorite destinations for birders in the U.S.
