摘要

The Least Grebe (Tachybaptus dominicus), the smallest NewWorld member of the grebe family (Podicipedidae), occurs from thesouthwestern United States and Mexico to Chile, Argentina and in theWest Indies (Trinidad, Tobago, the Bahamas, and Greater Antilles;Ogilvie and Rose 2003). This is a plump grebe with yellowish eyes, athin bill, and fluffy white tail coverts, ranging in length from 22-27 cm(8.25-10.5 inches). In basic plumage Least Grebes are brownish toblackish above with a white throat; in alternate plumage the throat isblack. Their wetland habitats are varied and include fresh and brack-ish ponds, lakes, slow-flowing rivers, and mangrove swamps that havegood vegetative cover along the edges. There are reports of nesting intemporary bodies of water (Storer 1992). Their compact floating nest ismade of aquatic vegetation and anchored to rooted plants. The eggs areincubated by both adults and hatch in about 21 days (Palmer 1962).The Least Grebe is reported to nest year-round in the tropics. Althoughconsidered non-migratory, they have been found to move long distances(Storer 1992). Norton et al. (2009) report that the Least Grebe has beenexpanding its range in the Greater and Lesser Antilles in the last de-cade. The few Least Grebes found in Florida to date are consideredmost likely to have been of the subspecies T d. dominicus from theWest Indies, although T d. brachypterus from Texas should not be dis-counted (Stevenson and Anderson 1994). Mean bill length is greater inT d. dominicus than in T d. brachypterus, a difference potentially ob-servable in the field, though there is much overlap between the two(Storer and Getty 1985).
