Methods


General Methods
Sampling & coverage of blocks

10km x 10km quads were each divided into four 5km x 5km blocks based on the UTM grid system. Of the total of 5335 blocks, 5323 were sampled; the 12 blocks unsampled were too difficult to get to or had little land mass.

Coordination of coverage
Management of this project was accomplished with the help of Regional Coordinators in ten regions defined in the NYS Ornithological Association's publication, The Kingbird.

Breeding Evidence Codes
Code Code description  (see handbook for full description & use suggestions)
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
P Pair observed in suitable nesting habitat during its breeding season.
S Singing male present (or breeding calls heard) on more than one date in the same place. A good indication that a bird has taken up residence if the dates are 7 days or more apart.
T Bird (or pair) apparently holding territory. In addition to territorial singing, chasing of other individuals of the same species often marks a territory.
D Courtship and display, copulation, agitated behavior or anxiety calls from adults suggesting probable presence of nest or young nearby; well-developed brood patch or cloacal protuberance on trapped adults. (For banders.)
N Visiting probably nest site, or nest building by wrens and woodpeckers.
B Nest building or excavation of a nest hole.
CO Category - confirmed evidence of breeding
DD Distraction display or injury feigning.
UN Used nest found. Must be carefully identified if it is to be accepted.
FE Female with egg in oviduct. (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.
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.
FS Adult carrying fecal sac.
FY Adult(s) with food for young, either carrying food or feeding young.
NE Nest with egg(s), undisturbed nest with a bird in incubation posture, eggshells found below nest, or identifiable dead nestling(s).
NY Nest with young seen or heard.
