The latest that I’ve observed Hooded Mergansers in the Wetlands was April 10 back in 2009 when a lone female was seen taking off from the water of the Wetlands, circled to gain altitude and left for points unknown. Typically, they leave by the last week in March. There have been 10-13 individuals in the Wetlands for the past several weeks, mostly females. There are three adult males and at least one male in immature plumage.
The pair in the photo above is often seen away from the other mergs. What does that mean? I hope it means that they’re going to stay and nest in the nest boxes placed in the Wetlands for just that purpose.
