The Return of the Mallard x Wigeon hybrid


I did of course see some Pine Grosbeaks today and also took some pretty cool photos (if I say so myself) but will wait to publish these such that your lust for the Piney has had a chance to return.

Instead I will treat you with pictures of a dodgy duck. In November 2015, the very competent Anne Kari Norland discovered a Mallard x Wigeon hybrid which stayed the winter and was also lucky enough to get itself blinged. It did not return subsequently until Anne Kari again discovered it a couple of weeks ago. In 2015 it was aged as a 1cy bird (this can be seen by comparing the tertial feathers from then and now – they were much shorter in 2015) so is now in its fifth calendar year. 

I find hybrids very interesting and with this bird there has been a change in its head pattern with it now having a vertical black line in the yellow cheeks which is a feature that many dabbling duck hybrids have and which reminds one of Baikal Teal (indeed over the years many hybrids have been mistakenly identified as Baikal Teal…)

those vertical black stripes in the cheeks are reminiscent of Baikal Teal
