A surprising 169 species of birds have been reported at Craters of the Moon.
Few birds remain during the harsh winter.
However, some are far northern species, difficult to find in the U.S. and therefore of interest to birders. Spring migrants reach a peak in May and early June, and as summer progresses, more than 70 species may nest. Sightings by visitors are important additions to our wildlife records. These codes reflect the likelihood of finding a given species in appropriate habitat throughout a given season.
