Field Checklist of the Birds of San Joaquin County
Compiled by David Yee
Revised July 1997 by David Yee and Waldo Holt
 

This checklist contains 328 native and 5 introduced species. The names
and taxonomic order conforms to  changes  made in the 41st  supplement to
the A.O.U. Checklist of North American Birds, 6th edition. The following
seasonal abundance categories reflect a species status at prime locations
in the proper habitat only. Out of necessity they are somewhat arbitrary.
An effort to show true relative densities rather than detectability has
been made. Abbreviations are as follows:

c  =  common,  almost always present, often in high numbers.
fc =  fairly common,  usually present, sometimes in
considerable numbers.
u  = uncommon,  should be present but often hard to detect
because numbers are few, occasionally found in
considerable numbers.
r  = rare,  not normally present but occurs annually, usually in
very small numbers. Also pertains to very localized
breeders with small breeding populations.

(Above symbols all indicate species that are
believed to be of annual occurrence.)

cas = casual,  four or more records for a given season but
not recorded annually. Some species may be
common in a given year.
acc = accidental,  three or less records in a given season.
h  = historical,  formerly recorded, now extirpated in
San Joaquin County.
 

R  = resident, most species nest in area.
S  = summer resident,  usually includes
periods of migration.
W  = winter visitor,  usually includes
periods of migration.
M  = migrant,  includes both of the two
following categories.
Sp = spring "migrant", most northbound.
F  = fall "migrant", most southbound.
*  = nests in county.
(*) = Formerly nested in county.
+  = suspected nester in county.
(species) = introduced species.
