A bird nest is the spot in which a bird lays and incubates its eggs and raises its young. In most species, the female does most or all of the nest construction, though the male often helps. In some polygynous species, however, the male does most or all of the nest building. Gulls nest in large, densely packed, noisy colonies. They lay two or three speckled eggs in nests composed of vegetation. Broodiness is the action or behavioral tendency to sit on a clutch of eggs to incubate them, often requiring the non-expression of many other behaviors including feeding and drinking. Being broody has been defined as “Being in a state of readiness to brood eggs that is characterized by cessation of laying and by marked changes in behavior and physiology”. Broody birds often pluck feathers from their chest and abdomen, using them to cover the eggs. Nest rock egg seagull sea gull. 4K UHD 3840×2160 30p.
