Homm vii harpy
They will only tend a single chick, so if two eggs are laid, the first born will be fed and the second will perish from starvation. Chicks are hatched altricial, and thus are helpless with downy feathers and eyes open. The female will perform most of the incubation while the male is in search of food. Both parents incubate the egg for the 56 day incubation period. Harpy eagles invest a lot of time and energy into their offspring. Range age at sexual or reproductive maturity (male) 4 to 5 years.Range age at sexual or reproductive maturity (female) 4 to 5 years.Breeding season The breeding season for harpy eagles begins in April or May and lasts until December or January.Breeding interval Harpy eagles breed once every 2 to 3 years.gonochoric/gonochoristic/dioecious (sexes separate).
( Rettig and Hayes, 1995 Rettig, 1978 de Carvalho, jr. Pairs of harpy eagles only breed once every 2 to 3 years. Juveniles do not reach maturity until 5 or 6 years old, at which time they often return to their original nesting area to breed. Juveniles often stay near their parents for some time and will occasionally beg for food. Both parents tend the chick for 10 months, well after the chick fledges between 6 and 7 months of age. Eggs are incubated for an average of 56 days. The female lays two eggs, but will raise only one chick. These impressive nests are reused by breeding pairs every year. The nests are built 27 to 43 m above ground, and consist of woven sticks lined with soft vegetation and animal fur. Harpy eagles construct large nests that measure 1.2 m thick and 1.5 m across. The breeding season for harpy eagles coincides with the start of the rainy season which usually begins in April or May. The mating pair of harpy eagles does not have a courtship display before mating, and will mate multiple times over a period of a few days. During the nest building phase, the pair will rarely radiate more than 180 m from the nest. They build their nests in large, tall trees, high above the forest floor. This activity seems to help them to preserve their bond. They will occasionally rub their bills together for a few seconds before going back to work. The pair builds the nest together and chirp to each other while doing so. Harpy eagles form breeding pairs that last for life. Their bills are black and their feet are yellow with black talons. The crown of harpy eagles consists of long black feathers which raise when threatened, though some theorize they also raise them to direct sound to their ears.
The head, thighs and vent are light gray and the nape has a dark band across it. The breast, belly, and flanks, are light grey with horizontal black stripes. The tail is made up of long gray feathers with horizontal black bars. The mantle, scapulars, the top of the secondaries and primaries, secondary coverts, greater primary coverts, and the rump are slate black in color, but can vary to gray. Females are normally larger with an average weight of 7 to 9 kg, while the males weigh an average of 5 to 8 kg. Harpy eagles are the largest species of eagle with a body length that can range from 89 to 102 cm and a wing span of 2 m. ( Beacham, 2000 Fowler and Cope, 1964 Frost, 2007 Grzimek, 2003 Merrick, 2006 Rettig and Hayes, 1995 Tingay, 2010 Trinca, et al., 2008 de Carvalho, jr. They generally are found in mid to upper levels of rain forest canopies where they are able to find preferred prey.
They prefer undisturbed forests but will also hunt along open patches of land. Harpy eagles live in the canopies of tropical lowland rainforests. They are found from southern Mexico to the eastern part of Bolivia, southern Brazil, and northern Argentina. Harpy eagles ( Harpia harpyja) are distributed throughout Central to South America.
