Male pintails

I am still working on the identification plates to be published in the June 2010 issue of the ornithological magazine Anser. Here is how to tell a first-winter male from an older one: a bit smaller body, rounder head, shorter and duller beak, and shorter tertials often obscured by the shoulder feathers. In flight the duller wings are also worth noticing.

surprisingly the simplicity which you manage to reproduce perfectly the volume and color of the ducks and mammals.
