Summary
[edit]DescriptionEared grebe on nest Sand Lake Wetland Management District 01 (14306252342).jpg |
An eared grebe incubating eggs on a floating nest on Sand Lake Wetland Management District. Eared Grebes nest in dense colonies. Both parents help build the well-concealed nest, which is a floating platform of weeds anchored to emergent vegetation in shallow water. Both male and female birds incubate the three to four eggs for about 21 days. As soon as all the young have hatched, the family leaves the nest. Both adults feed and tend the young, sometimes splitting the workload about 10 days post-hatching, with each parent taking half of the brood. The young are generally independent after 21 days. They winter in large concentrations on Great Salt Lake and Mono Lake. Photo: Tom Koerner/USFWS |
