Yellow Wagtail - autumn

Motacilla flava

Autumn passage has been recorded from the 1st July to the 30th October, with two November records.

There have been very few recorded in July and early August.  Peak passage took place from mid August to September.  The end of August has clearly been the time of maximum presence, when the largest concentrations of up to 50 birds were noted at Skokholm and Talbenny during the 1960’s. Betts (1992) notes “up to 150 in August 1952” at Skokholm but is not date specific, so these could not be fitted into the histogram.  Passage has tailed off rapidly during October. There have been two November occurrences, on the 2nd at Mullock in 1981 and on the 18th at Skokholm in 1967.
