About the Horned Grebe
The horned grebe or Slavonian grebe is a relatively small and threatened species of waterbird in the family Podicipedidae. There are two subspecies, P. a. auritus, which breeds in Eurasia, and P. a. cornutus, which breeds in North America. The Eurasian subspecies is distributed over most of northern Europe and northern Asia, breeding from Iceland east to the Russian Far East. The North American subspecies spans most of Canada and some of the United States. A small population was cited in Greenland in 1973, but is not mapped or further mentioned by subsequent authors.

ID tip
The species can be recognised by its orange-red and black breeding plumage, its black and white non-breeding plumage, and its characteristic "horns". It is 31–38 cm (12–15 in) long, has a wingspan 55–74 cm (22–29 in) wide and weighs 300–570 g (11–20 oz). It has a moderately long neck, flat forehead and a rear crown of black feathers. Its beak is straight and pointed, with a white tip. The breeding plumage has bright erectable "horns", black fan-shaped cheek feathers and an overall red-and-black colour. Voice: Young begin calling for begging purposes in a slightly trilled peeping noise, similar to that of a domestic chick. As they mature, their song changes to a more adult-like chittering. Their typical advertising call is loud and nasally "aaarrh" descending in a pitch and ending in a trill.
