Two hundred and twenty avocets, bitterns, cormorants, dowitchers, egrets, falcons and grebes roosted at the Kansas Wetlands Education Center on Thursday in the form of USD 428 second-graders for the first annual education day to learn about the wild, wonderful wetlands in Barton County. The children were divided into seven groups, all named for birds that visit CB. The event was hosted by the Friends of Cheyenne Bottoms. Migrating to seven learning centers to study about our feathered friends in the central flyway, students learned that some birds fly all the way from the Arctic Circle to South America through Cheyenne Bottoms each spring and each fall.
