Whilst birding the Sabya area in summer 2015 I came across Arabian
Babblers in nearby areas with different bill colours. In the filed guide to the
region it says these are different subspeics with the yellow-billed birds the
Yemen race. HBW, however, does not mention bill colour as a distinguishing feature
between the races, so I do not know which is correct. The bird with the dark
bill was seen at Phil’s Fields and the one with the yellow bill at Sabya Waste
Water Lagoons only about ten kilometres away.
