Birds You Can Only See in South Texas (Within the United States)

One of the Valley's most iconic birds. The only place in the U.S. where this tropical jay is a year-round resident — common and conspicuous at every major nature center.

Altamira Oriole

The largest oriole in the U.S., known for its pendulous woven nest up to 26 inches long. Its U.S. range is entirely limited to the lower Rio Grande corridor.

Plain Chachalaca

The Valley's original alarm clock — dawn choruses of cha-cha-lac! from a dozen voices at once are a quintessential Rio Grande Valley experience. Found nowhere else in the U.S.

Hook-billed Kite

A handful of pairs along the Rio Grande constitute the entire U.S. population. Its specialized diet of large land snails limits it to humid subtropical forest — exactly what the lower Rio Grande corridor provides.

Ferruginous Pygmy-Owl

Endangered resident

Endangered in Texas and found only in the Rio Grande Valley within the U.S. A small diurnal owl of dense thornscrub, heard far more often than seen.

Ringed Kingfisher

The largest kingfisher in the Americas — 15–16 inches long — found in the U.S. only along the lower Rio Grande. Its rattling call is audible from a distance.

Audubon's Oriole

A secretive oriole of dense thornscrub, far more often heard than seen. Its U.S. range extends barely across the Rio Grande from Mexico. Salineño is the most reliable U.S. site.

Clay-colored Thrush

Rare resident / vagrant

The national bird of Costa Rica has established a tiny breeding foothold in the Brownsville area and at Quinta Mazatlán. U.S. sightings are almost entirely from South Texas.

Tropical Parula

A warbler whose U.S. range is limited to the lower Rio Grande Valley. Nests primarily in Spanish moss in mature riparian forest — habitat that is now extremely limited.

Rose-throated Becard

One of the Valley's most sought-after birds. Pairs occasionally nest in the U.S. at Bentsen and Santa Ana NWR — the only reliable U.S. sites for this striking Mexican species.

Northern Jacana

A remarkable wader that walks on floating vegetation using its extraordinarily long toes. Resaca de la Palma State Park has hosted the most consistent U.S. population.

White-collared Seedeater

A tiny finch-like bird of weedy edges along the Rio Grande. The U.S. population has fluctuated but is most reliable at Zapata and the Laredo area — the northernmost outpost of a Central American species.
