Subspecies: brachypterus
Adult in alternate plumage. The yellow eye is characteristic among the grebes, and makes any confusion with Pied-billed Grebe unlikely - the two are often seen together, at least outside the breeding season.
Subspecies: brachypterus
Adults in basic plumage. Funny to see how the otherwise cute little bird get an almost grotesque expression when it opens its bill.
Subspecies: brachypterus
Adult. The bill looks rather, but otherwise the bird looks as if in a basic plumage. According the BNA (Birds of North America) the alternate plumage is a result of wear rather than caused by molt.
Subspecies: brachypterus
1 pair with two pullus. Notice the different head and throat markings between the two young - apart from the deformity on the front of the rear one. The adult birds are still in alternate plumage.
