March 25, 2016 – Ethiopian Bush-crow or Stresemann’s Bushcrow (Zavattariornis stresemanni)
These starling-like corvids are endemic to Ethiopia, found only in a small region of semi-arid grassland with tall acacia bushes. Outside of the breeding season, they forage for insects in small flocks with other bush-crows and sometimes White-crowned starlings. Pairs build their enclosed nests from thorn sticks, dung, and dry grasses, at the top of acacia bushes. Due to their small range and specific habitat requirements, they are threatened by changes in the density of vegetation in the region, leading to their classification as Endangered by the IUCN.
Here is an interesting article describing some possible reasons for their unusual range: http://birdingfrontiers.com/2014/01/30/the-ethiopian-bush-crow/
