Sex; not relevant here. Age; possible all adult, not important here. Subspecies; walleri (though not possible to tell on this photo). Udzungwa Mts., July 2007. Copyright@; Louis A. Hansen. Typical flock of starling, if there were Kendrick’s starling among then they would seem slightly shorter tailed and male in this species have no rufous-chestnut in the flight feathers.
