Northern Pintail Anas acuta
Fairly common passage migrant and winter visitor. Very scarce in summer. RBBP.
Flock of Pintail at Alkborough Flats on November 15th 2015 (Graham Catley).
The wintering Pintail population is currently of the order of 500 birds focused primarily in The Wash at Frampton Marsh and Freiston Shore and on the Humber at Alkborough Flats. Inland small flocks occur regularly but rarely get into double figures. Birds increasingly summer and in 2018 three pairs were noted at three separate sites, but there was no other evidence of breeding. Hollings (2010) in the 2007 RBBP report indicated confirmed breeding took place that year at an undisclosed site in the county where 7 ducklings were seen. The only instance of confirmed breeding in the last 29 years to 2019.
