Some very interesting bird behaviour on the north side of the Taw Estuary this aft which I have never seen before. At Ashford Strand there were 3 Sawbills, one male Goosander which was some distance from a male Red breasted Merganser & a female Goosander close together acting as though they were a pair. Even more unusual was this behaviour was repeated by 3 more Sawbills when I got down to Pottington & they were not the same 3 birds that were Ashford Strand. Another male Red breasted Merganser at Pottington which had paired with a female Goosander chased away a male Goosander! Maybe these 2 male Red breasted Mergansers think they are bonding with female Red breasted Mergansers, perhaps they cannot see the difference? What do you think.
