Guide to Boreal Birds
Duck-like Birds Overview
The mating display of the Western Grebe is spectacular, with both members of a pair paddling vigorously and churning across the surface of the water in an upright posture. Sometimes many pairs in a colony display simultaneously. During migration Western Grebes fly in loose flocks but spread out to feed during the day. On their coastal wintering grounds these birds often fall victim to oil spills and to insecticides that accumulate in their food, build up in their bodies, and reduce their breeding success.
