Grebes are small to medium-large in size ranging from the least grebe (Tachybaptus dominicus), at 120 g (4.2 oz) and 23.5 cm (9.3 in), to the great grebe (Podiceps major), at 1.7 kg (3.7 lb) and 71 cm (28 in). Despite these size differences grebes are a homogenous family of waterbirds with very few or slight differences among the genera.
As of the 2020 United States population census, [1] [2] the 62 counties of the State of New York are subdivided into 933 towns, 62 cities, and 10 American Indian reservations. Towns in New York are considered a third-level administrative division and a minor civil division by the US Census Bureau , in contrast to cities and villages, which are ...
The pied-billed grebe breeds in south-central Canada, throughout the United States, Central America, the Caribbean, and temperate South America. [10] These grebes may lay up to two sets of eggs a year. [13] Their nests sit on top of the water, their eggs sitting in vegetation that resides in the water. [17]
The calls of Clark's grebe are similar to its western counterpart, however, during courtship the birds make an 'advertising call' to attract mates -this sounds like a single, extended kreeeed as opposed to the two-note kreed-kreet of the western grebe. [4] The calls of the grebe tend to vary very little between sexes.
The western grebe has a straight bill with a dull green-yellow color as opposed to the Clark's grebe, which has a slightly upturned, bright orange-yellow bill. In both species the male has a longer and deeper bill than that of the female, making it a distinguishing feature. [2] All species of grebes display the pattern of lobed feet.
One day after we learned that the Duchess of Sussex was spotted lunching at Lauduée and shopping for baby clothes at Bonpoint in New York City, royal watchers were treated to a real royal appearance.
The great crested grebe and its behaviour was the subject of one of the landmark publications in avian ethology, Julian Huxley's 1914 paper on "The Courtship‐habits of the Great Crested Grebe (Podiceps cristatus)". [15] [16] Conservation efforts have been taking place on New Zealand's Lake Wānaka since 2013. [17] [18]
Western grebes nest in colonies on lakes that are mixed with marsh vegetation and open water. Western Grebe nests are made of plant debris and sodden materials, and the nest-building begins roughly around late April through June. The construction is done by both sexes and is continued on throughout laying and incubation. [11]
