Brown ibis ( Plegadis falcinellus )

The brown glossy ibis ( Plegadis falcinellus ), often Braunsichler or only glossy ibis called, is a globally widespread Ibis .

External features

Brown ibis reach a body length of 55 to 65 centimeters and have a wingspan of 80 to 95 centimeters. They weigh an average of 500 grams. The predominantly dark bird with the typical ibis shape has brown, shiny purple plumage. The wings and tail have a metallic sheen. The long, downwardly curved beak is an adaptation to foraging in mud and water.

The brown ibis is very similar to the ibis . It can be distinguished from this, however, by the fact that the bare reins skin in the splendid dress is bluish gray in the brown ibis (red in the ibis), that the white edge of the rein extends to the eye and not around the eye as in the ibis. The legs of the brown ibis are also reddish-brown (not red as in the ibis). Nestlings and young birds that have just fledged also have a striking, light, flesh-colored beak.

distribution

The brown ibis occurs in Africa , Europe , Asia , Australia as well as North , Central and South America , but probably originates from the Old World .

The brown ibis is very unstable as a breeding bird. It breeds in large numbers in some places, but then leaves this breeding site for some time or forever for no apparent reason.

habitat

The habitat of the brown glossy ibis includes wetlands, lakes, swamps , lagoons and rivers.

Reproduction

Egg ( Museum Wiesbaden Collection )

In Europe the brown ibis is a migratory bird . It does not arrive at the breeding site until April from the wintering areas in the Mediterranean and tropical Africa and leaves it in August or September. Both sexes participate in the construction of the nest. During the brood, males and females break away, with the male breeding mainly at night.

The incubation period for the two to five, maximum seven eggs is 20 to 23 days.

The young are able to fly after six to seven weeks.
