Create a 5 pages page paper that discusses black-crowned night heron. Black-crowned night herons are believed to be monogamous. “Pair formations are signaled by males becoming aggressive and performing Snap Displays, in which they walk around in a crouched position, head lowered, snapping their mandibles together or grasping a twig” (Ivory). The Advertisement Display or Stretch Display, occurring after the Snap Display is the central feature of male Night Herons in attracting females. In the Advertisement Display, a male bobs his head to the level of his feet so as to give a snap-hiss vocalization. Preening and twig shaking are the most notable characteristics of their songs. According to Ivory, these displays pass a social stimulus, which plays a crucial role in ensuring successful reproduction in colonial species. Although the female attracted towards a displaying male is rejected at first, she is gradually allowed to enter his territory. Then, this newly formed pair engages in mutual billing. It is observed that the legs of both male and female Night Heron turn pink at the time of pair formation. Generally, Night Herons engage in copulation on the very next day the pair is formed and it may take place on or near the nest. As Ivory points out, Black Crowned Night Herons build nests on a colony basis and the males initiate nest building. Eggs (a clutch size of 3-5 eggs) are laid four to five days after the pair formation and it happens at two-day intervals. The incubation period lasts 24-26 days and this process is carried out by both adults. On the first day, the eggs are green and it will eventually turn to pale blue (Ivory). Research-based observations indicate that Night Herons wet their feathers on hot days to provide sufficient cooling facilities to the egg. The young leave the nest nearly after two weeks of birth even though they do not go far from the nest. The young Night Herons may be clustered at the tops of trees after three weeks. However, the young will be able to fly better within 6-7 weeks and therefore they may go far away from the nest for feeding grounds. Studies show that the parent Black Crowned Night Herons cannot recognize their own brood during this time and hence they may accept other young brood.
