Not been many birds recently so I wonder if anyone can resolve this one for me. The stilts were taken at pensthorp wildlife park in 2008 but I am not sure if they are european or north american stilts. the species look rather similar to each other but the north american species has more black on like the second image but I think the north american ones alway have some black on the head unlike the first image.
