Several subspecies ...breeds in the
Balkans, S to Turkey, Iran and Afghan
...winters in Nigeria to Sudan.
Little trotty wagtail he went in the rain,
And tittering, tottering sideways he neer got straight again,
He stooped to get a worm, and looked up to get a fly,
And then he flew away ere his feathers they were dry.
(John Clare, 1793-1864)
