Non-Breeding Birds Distribution Map

Short-tailed Shearwater (Puffinus tenuirostris)

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.

NatureMapping observations reported by townships throughout the year.
