P = Permanent resident. Present year-round, but may
move up or down in elevation, and some of the population may move in or out
of the area.
M = Migrant. Present only during migration in spring and/or
fall months. Some individuals may remain in the area.
S = Summer resident. Present during the breeding season.
Arrival for some species may begin very early in spring, and some birds may
remain late into fall.
W = Winter. Present only during winter months. Arrival
for some species may begin early in fall, and some individuals may remain
late into spring.
SU = Status undetermined. Suitable habitat exists within
the area for these species, but records are few or nonexistent. Individuals
have been recorded in suitable habitat elsewhere in Clackamas County.
Status Codes:
A = Abundant. Easily found in high numbers with minimal
effort.
C = Common. Easily found, though perhaps not in high numbers.
U = Uncommon. Always present in low numbers. May require
focused search in suitable habitat.
R = Rare. Always present, but in very low numbers. Should
not be expected.
O = Occasional. Occurrence of a few individuals at irregular
times. Not to be expected every year.
I = Irruptive. Not present every year, with wild fluctuation
in yearly population numbers. In contrast to the status "Occasional", this
pattern of occurrence is part of the species natural distribution patterns.
L = Low elevation occurrence
H = High elevation occurrence
Habitat Categories
A = Rivers and streams. Species for whom the aquatic element
of habitat is most critical.
B = Ponds, bogs, swamps, and wetlands. Species for whom the aquatic
element of the habitat type may or may not be critical. Includes species associated
with vegetation of wet areas.
C = Riparian zone. Species associated with streamside vegetation,
but not necessarily with the aquatic element.
D = Recent clearcuts, reproduction timber under 40 years, and associated
edge habitat.
