Orange-Crowned Warbler Terranea Resort Palos Verdes Penninsula Southern California 409
"Three of the four North American subspecies of Orange-crowned Warbler occur in the Pacific Northwest. Each has a different status and migration pattern. Alert field observers can often differentiate between coastal birds and interior birds, contributing to our knowledge of their distribution and alerting us to changes in their status. In eBird, the three subspecies are
lutescens (“Pacific Coastal”),
orestera (“Interior Montane”) and
celata (“Taiga”).
The last two are also clumped into “Gray-headed.” As this note points out, there are many times when birders are unable to confidently assign an individual to a subspecies. If in doubt, call it an Orange-crowned Warbler and avoid creating error in the data." ebird.org
