Sand Lake National Wildlife Refuge near Aberdeen, S.D., is a favorite place in the spring. I went there for a few days last week hoping to see Western Grebes do their courtship dance. There also was a good show by Forster’s Terns diving for minnows, and a Black-crowned Night-Heron first in leisurely flight, then turning up the speed as a Yellow-headed Blackbird gave chase. Plus a Cattle Egret in a usual place. The grebes also were dancing on Lake Osakis in west central Minnesota. We visited there, too, but missed the dancing. Many grebes were on nests, so the courtship dancing might have been finished. The lake holds a significant grebe colony.
