Winter Sounds of the Lower Rio Grande

Written by Bob Sundstrom

This is BirdNote.

[Sounds of Northern Beardless Tyrannulet and Plain Chachalacas] 

You’re listening to the sounds of winter in the subtropics. We’re in the lower Rio Grande Valley of Texas, where the Rio Grande borders Mexico. And here, birds commonly found in Central America reach their northern-most range. 

A Green Jay, the very picture of a tropical bird feathered in green, yellow, and blue, offers its varied voices [Green Jay, sample of sounds]. Now a secretive White-tipped Dove calls eerily from the forest floor [White-tipped Dove].

A tiny flycatcher with a very long name - a Northern Beardless Tyrannulet [song of Northern Beardless Tyrannulet] sings a distinctive refrain. Nearby, an Audubon’s Oriole seems to sound like a child just learning to whistle [song of Audubon’s Oriole].

Black-bellied Whistling-Ducks demonstrate that they are indeed ducks that whistle [whistle of Black-bellied Whistling-Ducks], while the large, chicken-like Plain Chachalaca shouts loud enough to drown out all others [calls of Plain Chachalacas].

But as night falls and the subtropical birds go quiet, an Eastern Screech-Owl trills [call of Eastern Screech-Owl].

The bird sounds for today’s show come from the Macaulay Library at the Cornell Lab of Ornithology. For BirdNote, I’m Mary McCann.
