The acacia jay ( Zavattariornis stresemanni ), sometimes also called the Zavattari bird , is a songbird native to Ethiopia . It belongs to the corvidae family.
Systematics
The acacia jay was discovered in 1937. Edoardo Zavattari, the former director of the Zoological Institute at the University of Rome , observed him in April 1937 during two expeditions to the southern Ethiopian bushland. It was named after the German ornithologist Erwin Stresemann . In 1938 it was first described by the Italian ornithologist Edgardo Moltoni and classified in the monotypic genus Zavattariornis .
features
The starling-like birds reach a size of 30 cm. It is blue-gray in its entire appearance, but is almost white in color towards the forehead. The throat and chest are cream-colored and the wing feathers and tail are glossy black. The nibs are lightened brownish. Males and females are similar, the young birds are a little more dirty in color. The iris is brown and the eyes are surrounded by a light blue band of bare facial skin. The beak, feet and legs are black.
distribution and habitat
Its occurrence is limited to thorn, short grass and acacia savannahs in southern Ethiopia near the places Yabello (Jabello), Mega and Arero.
Way of life and reproduction
Outside the breeding season it is very sociable. They like to stay in the company of the white-headed starlings ( Spreo albicapillus ) and form groups of four to ten birds. Their diet consists of insects. The breeding season is from February / March to May / June and the nests are built in acacia bushes at a height of 6 m . The clutch usually consists of five to six cream-colored eggs with lilac-colored spots. The nest is spherical with a tubular entrance at the top. Due to the long breeding period, it is possible that several breeding pairs visit the nest and that young birds from previous breeding seasons help in rearing their young.
