Pied < > Black-eared Wheatears, Touran, Iran, April 2017
In the Touran area, several wheatears were observed which
showed characters indicative of Pied < > Black-eared Wheatear intergrades. Such
individuals are known to occur in this region. Some males can be mistaken easily
for Finsch's Wheatear in a brief view. In the upper frames are two images of the
same individual. In the relaxed posture on the left, this individual looks very
like Finsch's, with an apparently broad black 'bridge' between throat and
scapulars. However, the black on the throat is more restricted than on
most Finsch's, in which the area of back extends down onto the upper breast. In
the posture in the right, it can be seen that, while there is a connection
between throat and scapulars (unlike on Black-eared), this is very narrow and
incompatible with Finsch's. The lower bird, a first-summer male, also shows
features suggesting it is an intergrade.
