The Least Grebe /zambullidor menor (Tachybaptus dominicus)

Voice: Loud, nasal, high-pitched “beeek” or high-pitched, buzzy, chattering “vvvvvvvvvvvvvvv”

Least Grebe
Status: Uncommon to locally common resident of freshwater ponds and oxbow lakes (resacas) in south Texas. Occasionally found along the Rio Grande. Numbers fluctuate from year to year. Some years they can be fairly common (in good habitat), while other years virtually absent. Birds range from Laguna Atascosa NWR in the east to the Falcon Dam area in the west. Not found on the immediate coast.

Habitat: Sheltered freshwater ponds bordered with vegetation.

Best Spots: The resaca at Sabal Palm Grove, Willow and Pintail Lakes at Santa Ana NWR, McAllen Sewage Ponds, World Birding Center Edinburg Scenic Wetlands, and the “dike” pond at WBC Bentsen SP, common and highly visible year round feeding in the resaca at Resaca de la Palma Stat Park

Similar Species: Pied-billed Grebe. Least Grebe can be distinguished from Pied-billed Grebe by its thinner bill, golden eye, and contrasting (and sharply demarked) dark crown. These buoyant birds often show tufts of white feathers in the rear of the bird.

A Birder's Eye View of the Seasons in the Lower Rio Grande Valley  

Welcome to a birder’s eye view of the seasons in the Lower Rio Grande Valley. Enjoy our annual cycle! The resulting avifauna in deep South Texas is the most diverse north of the Mexican border. The four county area that makes up the lower Rio Grande Valley has recorded over 500 species of birds. This is more species of birds than have been recorded in all but two or three entire states. Small wonder that birders from across the continent make pilgrimages to the region. Happy Birding!
