Over 227 species of birds have been observed within Valley Forge National Historical Park, and the Valley Forge Bird List is intended to reflect their present status.

It has been developed based on published and online records, including the online eBird resource maintained by the Cornell University Laboratory of Ornithology, the Pennsylvania Bird Atlas maintained by Pennsylvania State University, and field observations by park staff, members of the Valley Forge Audubon Society, West Chester Bird Club, and volunteers over the past 40 years.

The list is organized by groups of closely-related species, and describes the seasons in which these species are most likely to be detected and how plentiful they are in each.

Bird List Key

Seasonal Status

Spring – residents and migrants

Summer – mainly breeding residents

Fall – residents and migrants

Winter – mainly residents

Relative Abundance

Abundant - may be seen or heard daily in suitable habitat and season, and counted in relatively large numbers.

Common - may be seen or heard daily in suitable habitat and season, but not in large numbers.

Uncommon - likely to be seen or heard monthly in suitable habitat and season; may be locally common.

Rare - present in suitable habitat, but usually seen or heard only a few times during the indicated season.

Occasional - occurs in the park at least once every few years during the indicated season, but not necessarily every year.

Extremely Rare (listed at end of each bird group) - species for which Relative Abundance rating in Valley Forge National Historical Park does not exceed Occasional in any one season. These may most often be encountered during spring or fall migrations.

Special Notes

***** Population reproduces in the park.

# Irruptive species: species that, when present (generally every 2-4 years in winter), may occur in relatively large numbers.
