Digital Warbler Song Reference

For help mastering warbler songs and calls, a compilation of 310 songs and calls for 57 species of warblers is now available from the Cornell Lab of Ornithology’s Macaulay Library -- the largest archive of wildlife sounds in the world. Originally released in 1985 as an LP record, Songs of the Warblers of North America is the most comprehensive audio guide to warblers available anywhere. The newly digitized version can be used on any device that plays MP3 files and is $14.99 at www.macaulaylibrary.org.
