The 'Wisconsin Atlas Project' provides a free online bird audio service for
the identification of birds of the area. This may be their investment in
improving long-term data collected by more skilled observers.
Remember, we live in a zone featuring both Western and Eastern birds . This
site will omit some species which occur here. It does cover the Eastern
species some of which migrate through while others maybe stragglers at some
point. Go there when you hear an unfamiliar song.
This link can be great for a 'tune-up' for the migration or you can improve
your enjoyment of the background sounds in your yard or 'patch' and on field
For example, if you are travelling to Roche Percee you may be surprised to
hear a Field Sparrow a regular species in small numbers at this location.
Other species of interest ar Roche Percee include: Yellow-throated Vireo,
Lazuli Bunting, Willow Flycatcher, Rock Wren, Black-headed and Rose-breasted
Grosbeak plus others. Learn the plaintive call of Eastern Wood-Pewee to see
