New Mexico 2000-2011

Methods


General Methods
Sampling & coverage of blocks

Based on the UTM grid, New Mexico is divided into 146 50km x 50km atlas squares. Each atlas square contains 100 5km x 5km blocks. The blocks are further divided into 1km x 1km 'kilos' used for determining relative abundance of species sampled. At least one priority block has been randomly assigned per square. Habitat priority and supplementary blocks are also included.

Coordination of coverage
This project is being managed with the help of regional organizers.

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 between June 1 and July 31, but not believed to be breeding in the block.
PO Category - possible breeding evidence
X Species (male or female) observed in suitable nesting habitat during its safe dates.
S Singing male detected once in possible suitable nesting habitat.
PR Category - probable breeding evidence
M 7 or more singing or territorial birds of a species detected within a block on one day.
P Pair observed in suitable nesting habitat during its breeding season.
T Permanent territory presumed through song at same location on at least 2 occasions 7 days or more apart.
C Courtship behavior or copulation.
N Visiting probable nest site.
A Agitated behavior or anxiety calls from adult.
B Nest building by wrens, verdins, or excavation of holes by woodpeckers.
CO Category - confirmed evidence of breeding
NM Bird carrying nesting material, except for some species of wrens and verdins.
NB Nest building by any species except wrens, verdins, and woodpeckers.
PE Physiological evidence of breeding, e.g. highly vascularized, edematous brood patch or egg in oviduct based on bird in hand. (For banders.)
DD Distraction display or injury feigning.
UN Used nest found. Must be carefully identified if it is to be accepted.
FL Recently fledged young (either precocial or altricial) incapable of sustained flight, restricted to natal area by dependence 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, or eggshells found below nest.
NY Nest with young seen or heard.
