Field notes

  • It is the smallest grebe species in the Americas, measuring only about 21 to 27 centimeters in length.
  • Both sexes feature distinct bright yellow irises that stand out against their slate-gray plumage.
  • They are opportunistic nesters and can breed at any time of year if water levels and food supply are sufficient.
  • Like other grebes, they ingest their own feathers to line their stomachs, which helps protect the digestive tract from fish bones.
  • Despite being weak fliers, they are highly mobile and can quickly colonize temporary ponds created by heavy rains.
Habitat
Small freshwater ponds, lakes, marshes, and ditches with dense emergent vegetation.
Range
Southern Texas and the West Indies through Central and South America to northern Argentina.
