NINTH REPORT OF THE WASHINGTON BIRD RECORDS COMMITTEE (2008-2010)

摘要

Since its eighth report (Aanerud 2011) the Washington Bird Records Committee (WBRC) has reviewed 291 reports representing 92 species and seven other subspecies and forms, accepting 232 of them, an acceptance rate of 80%. Most of these birds were observed between 2008 and 2010. Six new species and one subspecies group are added to the Washington state checklist: Providence Petrel (Pterodroma solandri), Hawaiian Petrel (P. sandwichensis), Greater Pewee (Contopus pertinax), Yellow-bellied Flycatcher (Empidonax flaviventris), Variegated Flycatcher (Empidonomus varius), Bell's Vireo (Vireo bellii), and Interior or Lead- colored Bushtit (Psaltriparus minimus plumbeus). In addition, the WBRC removed two species, the Mute Swan (Cygnus oLor) and American Black Duck (Anas rubripes) from the state checklist. The Washington state list now stands at 498 species.
