Blue-winged Teal

Erika and I found Blue-winged Teal in a small pond on 15 April 2017 in the Carleton College Arboretum.  The flock consisted of three males and three females, not surprising, since teal pairs form in the late winter or as they migrate north.

Blue-winged Teal populations crashed in 1990 after several drought years. By 2000, their numbers more than doubled. This increase may mean, if appropriate conservations are initiated, teal can recover from recent wetland destruction of prairie pothole wetlands (Rohwer et al. 2002).
