Their beaks are small, but they already have a sharp, hooked tip. During the day, parents share the concerns of raising them and meeting their needs.Īt first, the chicks are covered with soft gray down. During the breeding season in hot weather, the bird uses its beak as a scoop and cools the eggs with water to maintain the required temperature for hatching. Within 5 days, the female lays 1-3 eggs, which she warms most often at night. The material for the nest is papyrus and reed stems. The nest of this bird is a huge platform, with its base reaching a diameter of 2.5 m. In captivity, the Shoebill's mating ritual consists of nodding and stretching the neck, clicking its beak and making muffled sounds. Little is known about the mating behavior of this bird in nature. For example, in Sudan, it starts at the end of the rainy season. The start of the breeding season of the Shoebill depends on the region it lives in. Often, before eating a fish, the Shoebill rips off the head. ![]() After a successful hunt, the bird first separates the prey from the plants, and then swallows the edible part. Then, it immediately spreads his wings and rushes forward, trying to catch the victim with his large beak with a sharp hook at the end. The Shoebill sometimes slowly and carefully walks through the reed thickets until potential prey appears on the surface. Without moving, with its head lowered into the water, the Shoebill patiently waits for a fish to appear nearby. It usually feeds on fish, and it also catches frogs, snakes and even young turtles and crocodiles. Often feeding during the day, the Shoebill diligently examines floating islands of aquatic plants. They're docile with humans and do not express any threatening behavior to them. The bird is most active at dawn, however, it often hunts during the day. It can stand motionless for long hours in shallow water, resulting in descriptions of the species as "statue-like". The Shoebill is well adapted to life in swamps, as its long legs with widely spaced toes allow it to easily move on the muddy soil. When Shoebill chicks beg for food, they make sounds that sound uncannily like human hiccups. Bill-clattering is done by both adult and young birds, and it plays a role in communication of the species. Shoebills are mostly mute birds that perform bill-clattering displays at the nest, and adult birds in these displays have noted to emit a muffled cow-like moo and high-pitched whining sounds. It is flattened above and has shape edges. The most characteristic feature of this bird is the dull, straw-colored, erratically greyish-marked 18.8-24 cm long beak, which is hooked, wide and massive, and its shoe-like shape is what gives the bird its name. Unlike most birds, the eyes are located in front of the skull, which increases the field of binocular vision. The neck is relatively short compared to other long-legged birds (herons and cranes). The mass of the this bird normally ranges from 4 to 7 kg and males are heavier than females males weigh within an average of 5.6 kg, while females weigh within an average of 4.9 kg. ![]() ![]() The length from tail to tip of the beak ranges from 100-140 cm, while the wingspan ranges from 230-260 cm. Editio decima, reformata.It is overall a tall crested, grey-plumaged, black-legged stork-like bird that has a usual height measuring from 110-140 cm, with few individuals reaching up to 152 cm tall. Linnaeus C 1758. Systema naturæ per regna tria naturæ, secundum classes, ordines, genera, species, cum characteribus, differentiis, synonymis, locis. Someday we’ll find Late Cretaceous crows and maybe hamerkops, IMHO.īrisson MJ 1760. Ornithologie, ou, Méthode contenant la division des oiseaux en ordres, sections, genres, especes & leurs variétés : a laquelle on a joint une description exacte de chaque espece, avec les citations des auteurs qui en ont traité, les noms quils leur ont donnés, ceux que leur ont donnés les différentes nations, & les noms vulgaires Of course, that means the above list of taxa goes back much, much further. Pelicans (genus Pelecanus) go back at least 30 million years. Just think of all the transitional taxa between these terminal extant specimens, now extinct. The pelican is a short-legged, long rostrum hamerkop. Updated crown bird cladogram from December 2021.
