Non-Breeding Birds Distribution Map

Chestnut-sided Warbler (Dendroica pennsylvanica)

The Washington Gap Analysis Project created breeding bird maps only. The non-breeding birds (e.g., wintering, pelagic (coastal), and birds expanding their ranges) are represented only by NatureMapping sightings.

The Washington Gap Analysis Project could not find any historical research records (i.e., Breeding Bird Atlas, Breeding Bird Survey, Bird Banding and Recovery) for 73 species of birds. The Chestnut-sided Warbler is one of the species.

NatureMapping observations reported by townships throughout the year.
