P - Permanent Resident: some members of the species are present on the refuge all year, but not necessarily the same individuals.
S - Summer Resident: includes all species present only during the breeding season, except those which occur solely as passage migrants.
W - Winter Resident: present only in the non-breeding season.
M - Migrant: includes those species which occur on the YDNWR only as migrants en route to other destinations; does not include migrant species in which some fraction of the population remains on the YDNWR during the breeding season.
C - Casual: includes 1) species reported five or more times, but not to be expected on an annual basis (e.g., red-breasted nuthatch), 2) species which may appear fairly regularly as non-breeders or post-breeding dispersers, but in very small numbers (e.g., Eurasian wigeon, golden-crowned kinglet), and 3) very rare and/or sporadic breeders (e.g., red-throated pipit).
A - Accidental: includes all species which have been reported fewer than five times on YDNWR; several different groups fall within this category: 1) true vagrants (e.g., Common Cuckoo, Hoopoe, Siberian Accentor), and 2) species which owe their accidental status to a lack of ornithological field work at the right time of the year in the appropriate habitat (e.g., White-tailed Ptarmigan, Ivory Gull) and are to be expected in the future.
X - Extinct: no longer occurs on YDNWR.
* - known to have bred in the past and/or currently breeding on YDNWR.
