Least Grebe Gallery

Tachybaptus dominicus

eBird describes the Least Grebe like this:  This well named grebe is the smallest grebe and is very small for a waterbird. Medium-gray overall with pale fluffy sides. The face is dark in breeding plumage; lighter with white throat in nonbreeding plumage. Piercing yellow eye; thin, sharp bill. Widespread throughout Central and South America; very limited range in U.S. Found in marshy ponds, often with extensive vegetation. Found singly or in pairs. Frequently dives underwater.  All About Birds adds this descriptive information about the Least Grebe:  The Least Grebe is a tiny, almost metallic gray waterbird with a brilliant golden eye and a tuft of white at the stern. These chunky-bodied grebes spend their time in shallow freshwater or brackish ponds (and even flooded ditches) where they hunt insects and frogs. Completely at home in the water, they sometimes hide out with the body submerged and only the bill out of the water, almost like a tiny alligator. These birds are fairly common in tropical wetlands but reach the United States only in South Texas.

I saw my first Least Grebe on my August 31, 2020, visit to Christmas Mountains Oasis.  I noticed the solitary bird swimming in the large tank to the left of the hummingbird blinds on my first walk through the Oasis.  Later, Carolyn Ohl-Johnson, the owner, was excited to tell me about the Least Grebe and how unusual it was to have one at the Oasis.

“Cool Facts” about the Least Grebe from All About Birds…

  • On very hot days, Least Grebes may use their wings to cool eggs in their nest. They stand at the edge of the nest, facing outward, and rapidly flap the wings for a minute or more.
  • The concept of “wing loading” applies to both aircraft and birds and affects how they fly. Wing loading is the weight of the bird (or plane) divided by its wing area. Heavy birds with high wing loading, such as California Condors, are very steady in flight but have a hard time taking off. By contrast, the Least Grebe is light and has large wings for its size; this low wing loading means it is able to take flight from the water much more easily than heavier birds like grebes, coots, and loons.
  • The Least Grebe sunbathes by facing away from the sun, closing its wings and tipping them upward on its back. It fluffs out its body and head feathers. The skin underneath these raised feathers is blackish and helps to absorb the sun’s rays.
  • The Least Grebe can hide underwater with only its bill showing above the surface.
