The Coot's nest is built in shallow water from vegetation, and usually in the shelter of vegetation but can be in the open.
The Coots eggs are smooth and glossy, buff with dark brown spots. They are about 53 mm by 36 mm. Both parents incubate the eggs and look after the precocial nestlings, which, when newly hatched, are led to the water by their father.
An unusual adaptation to its life in water is the large, scalloped toes. These enlarged lateral lobes provide for efficient swimming. On land, the bird appears clumsy when moving around.
The appearance of baldness doesn't refer to the lack of feathers on the bird's head, but to their white markings. 'Bald' has several meanings, one of which is 'streaked or marked with white'. That's the meaning here, as in 'piebald', used to describe the black and white markings of a horse or other animal.
The phrase is very old and is referred to in John Lydgate's Chronicle of Troy, 1430:
"And yet he was as balde as is a coote." |
