The ibis bird is small in size, weighing up to 4 kilograms and growing 60-100 centimeters. The ibis has a slightly elongated, barrel-shaped body, planted on long thin four-fingered webbed legs. Movable thin neck of medium length, head slightly tilted back. In some ibis, a crest of feathers or a rounded leathery growth is present on the crown of the head. The wings are long and wide, consisting of 11 main feathers, which allows the bird in flight to reach speeds of up to 65 kilometers per hour. The tail is short, barely noticeable. Unlike other Ciconiiformes, ibises lack goiter sac and powder plumage.

Plumage

Ibis have one-color plumage. There are species that are fully white. There are ibises with black, gray, emerald, brown feather color. A striking representative of the ibis family is the red (scarlet) ibis. The body, neck, head, tail and legs of this bird are painted in burning red.

In some varieties of ibis, the main color is complemented by a contrasting shade. For example, in the black-faced ibis, the torso is colored lead and the neck is bright yellow; the white plumage of the body of a red-legged ibis contrasts with a bright red complexion; black-headed ibis is painted off-white, while the tail and neck are dark gray. Young ibis is characterized by a juicy, bright color of the pen. With each molt, the color of the feathers fades.


Beak

A distinctive feature of ibis is the beak. It is long, thin, curved down at the end. This part of the body is a hunting tool, therefore, by nature, the bird's beak is very powerful and strong. In some species of ibis, the beak tip is slightly expanded, which allows birds to more effectively hunt aquatic animals.

The birds plant a long beak in the muddy bottom and, digging it up, look for and catch prey. With the help of a long beak, they find food in crevices of stones and deep burrows. The tongue does not support in eating, as it is atrophied due to evolution.


Female and male: differences

Ibis lacks sexual dimorphism. Externally, representatives of both sexes differ from each other in size: males are larger than females by 200-400 grams.

Location

A large family of ibis is found around the world, with the exception of the northern regions. These are thermophilic birds that choose the tropics and subtropics for life, with rare exceptions moderate latitudes. The largest number of ibises are found on the east coast of Africa, in the north-west of Latin America, Australia. With rare exceptions, ibis is found in Europe and Russia.

Habitat

Ibis belongs to the group of near-water birds. Birds prefer to nest near water bodies, as they feed mainly on aquatic animals. For nesting birds choose an open area - forest edges, river valleys. Some species of ibis, such as warty ibis, are not attached to water bodies and equip their homes in dry places. They feed mainly on small vertebrates and plant foods. Ibis are found in the steppes and savannahs, rocky semi-deserts.

Ibis: Do they Migrate

Most species of ibis are migratory. Feathers living in North America fly to Colombia, Ecuador and Venezuela in the winter. European birds migrate to Africa and Asia for the period of cold weather. Japanese birds fly over the summer to Australia. Other "southern" species lead a sedentary life, however, in search of food they travel through the range, moving away from the nesting site for thousands of kilometers.

What do they eat?

The ibis food consists of insects and small vertebrates. Birds hunt mollusks, crustaceans, larvae. Adult individuals sometimes regale themselves with larger prey - fish, eggs of small birds, frogs. Ground ibis catch lizards, mice and earthworms. If possible, they eat bugs, snails, slugs, spiders and locusts.

In hungry times, ibises do not disdain to eat carrion or the remnants of food of predatory animals.

Lifestyle

bis are flocking birds. They live in colonies of 100-150 pairs. During nomadic bird families unite in a huge flock, which totals up to 1 million individuals. Birds fly together, in the places of recreation create the so-called "bird markets". Ibis are calm, peaceful birds. In their flocks take other birds, for example, spoonbills, cormorants, herons. All of them fly along the same route, and then they also return home together. Thanks to the powerful long wings, ibises fly quickly and well. In one day they cover a distance of several hundred kilometers.

Ibis leads a daily life. In the light hours, they hunt, slowly wandering around in shallow water and picking silt with their beaks in search of a crustacean or slug. Having hooked prey, the bird makes a sharp wave of its head, picking up food with its beak and swallowing whole. Ibis are careful birds. Sensing danger, they make a sharp flap of their wings and instantly rise into the air, hiding from the enemy in the crown of trees or shrubbery. At night, ibises climb into the nests and rest.

Breeding

Most ibis species are monogamous. By the age of three, young birds become sexually mature. The natural instinct makes them look for a couple and start breeding. Partners stay together for life. Together they share the burdens of building a nest, hatching and raising offspring. The nesting period for northern birds begins in March and lasts until early May. Ibises living in Australia and South America breed from September to January during the rainy season.

Ibis make nests in trees. Some species equip homes in thickets of reeds, reeds or papyrus. The nest is a wide deep bowl, assembled from flexible branches and stems. "Houses" have close to each other - so more likely to respond in time to the appearance of a predator and fly away.

The ibis female lays 2-6 eggs. In size, they are twice as large as chicken. The color of the eggs of some ibis is cream, while others have light blue or gray-green eggs. The incubation period lasts three weeks. Female and male hatch offspring in turn. Chicks are born small and helpless. They still do not see, and the body is covered with a rare grayish or brown wet fluff. Parents feed the young with insect larvae. On the fortieth day, the chicks take to the wing, however, they leave their father’s house only by three months of life. In the fall, young growth unites in flocks and migrates with adult birds. The plumage of one-year-old birds differs from mature ibises: it is not so bright and contrast. Only in the second year of life, after the first molt, the color of the pen will become the same as in adult birds.

There are 13 genera of ibises, which include 29 species of these birds. The most studied ibises are black-necked, bald, red-legged, chubate genera.

Natural enemies of ibis

Adult ibis do not have as many enemies as younger ibis. If nests are located on the ground, then foxes, wild boars, hyenas and raccoons encroach on eggs and chicks. Rats and ferrets prey on newly hatched cubs. True, this rarely happens, as adult ibis carefully guard the brood and, if necessary, repel the attacks of predators. Young ibis are hunted by birds of prey. Hawks, eagles and kites do not risk communicating with adult ibis, paying all their attention to young birds who are just learning to fly and who still do not know how to defend themselves.

The main enemy of the ibis is man. Agricultural activity, drainage of water bodies, deforestation, hunting - these factors have led to a serious reduction in the number of ibises. Most of the species of the family are on the verge of extinction. About 10 thousand years ago, the species of the flightless bird Xenicibis xympithecus disappeared from the face of the earth as a result of uncontrolled human hunting.

Ibis in the culture of Egypt

The ancient Egyptians revered ibis. The inhabitants of Egypt invariably depicted the God of wisdom and justice Jehuti (Thoth) with the head of an ibis. In ancient times, ibises lived throughout Egypt. Every year, the places of the nomadic birds chose the valleys of the Nile River. The ibis lived in the cities, freely pacing the streets and not being afraid of people. Dead birds were embalmed, some were buried with their owners. Archaeologists have found the mummified remains of ibis in the temple of Thoth, as well as numerous images of birds on the walls.

Scientists believe that the Egyptians worshiped the so-called "sacred ibis" (by the name of the species), but there is an opinion that in ancient times another species of birds nested in Egypt - the forest ibis, which was the symbol of the country. Later, the forest ibis was replaced by birds with white plumage and a black head, which were called "sacred". Today in Egypt, ibises are extremely rare, but in the south-east of Africa (Ethiopia, Kenya, Tanzania), the ibis population is plentiful.
