This spring Diana and I went to the Forest History Center near Grand Rapids, MN. It was migration season and this male Rose-breasted Grosbeak was one of the new arrivals. At this time of year, birds have fresh feathers so they look really sharp.
Warblers were abundant at the Forest History Center. This male Black and White Warbler was one that we spotted. Many warblers are very colorful but this bird is impressive even though its only black and white.
Here are two close-ups of that Virginia Rail. Notice how different the eyes look. Birds have a second eyelid called a nictating membrane. The bird on the left has closed this transparent membrane to protect its eye but it can still see through it.
