Prothonotary Warbler

The Prothonotary Warbler is a rare breeder in the Chicago Wilderness Region, common farther south. The CW Region appears to have always been on the northern fringe of this species' range. This rarely encountered species is poorly sampled by the BCN Survey and accurate trends cannot be estimated. Photo: © Heather Secker
