Methods


General Methods
Sampling & coverage of blocks

Each block consisted of 1/6 of a USGS 7.5 minute topographic quad. One priority block from each quad, i.e., 727 priority blocks were covered. 6 special blocks were sampled as secondary block coverage.

Coordination of coverage
Management of this project was accomplished with the help of regional coordinators.

Breeding Evidence Codes
Code Code description  (see handbook for full description & use suggestions)
OB Category - Observed: not breeding evidence
O Species (male or female) observed but not believed to be breeding in the immediate vicinity of the block. Birds seen before or after their normal nesting season dates, migrants, vagrants, and other birds suspected to be non-breeding are included.
PO Category - possible breeding evidence
X Species (male or female) observed in its breeding season in suitable nesting habitat, with no other indication of breeding noted.
PR Category - probable breeding evidence
A Agitated behavior or anxiety calls from adult.
P Pair observed in suitable nesting habitat during its breeding season.
T Permanent territory presumed through either defense (e.g. chasing of other birds) or song at same location on at least 2 occasions 7 days or more apart.
C Courtship behavior or copulation.
N Visiting probable nest site.
B Nest building by wrens or excavation of holes by woodpeckers.
CO Category - confirmed evidence of breeding
DD Distraction display or injury feigning.
NB Nest bulding or adult carrying nesting material.
UN Used nest found. Must be carefully identified if it is to be accepted.
PE Physiological evidence of breeding, e.g. highly vascularized, edematous brood patch or egg in oviduct based on bird in hand. (For banders.)
FL Recently fledged young (of altricial species) incapable of sustained flight or downy young (of precocial species) restricted to the natal area by dependance on adults or limited mobility.
FS Adult carrying fecal sac.
FY Adult carrying food for young.
ON Adults entering or leaving a nest site in circumstances indicating occupied nest. To be used for nests which are too high (e.g. the tops of trees) or enclosed (e.g. chimneys) for the contents to be seen.
NE Nest with egg(s).
NY Nest with young seen or heard.
