warbler studies /  by kelly heaton

Three studies of warblers for a new singing circuit (work in progress). The Red warbler lives in Mexico’s highlands, although its territory may become more northern as a consequence of climate change. The Cerulean warbler is considered to be at high risk of extinction due to human destruction of habitat. The Yellow warbler lives in North America and is thankfully not at risk for the moment.
