Blue-winged Teal

The Blue-winged Teal photograph above is one of my favorite photographs taken several years ago from a blind in Pierre, South Dakota. The teal below are from Rice County this spring (27 April 2011) when I was trying to photograph duck pairs. Blue-wing Teal are early migrants to Minnesota. They form pairs in the late winter or during spring migration. Nest failure can be over 90%--mostly due to mammalian predators. Blue-winged Teal numbers, however, depend on prairie wetland conditions. In dry years, populations fall. In wet years numbers can double (Rohwer et al. 2002).
