Florida 2011-2016

Methods


General Methods
Sampling & coverage of blocks

Each block consists of 1/6 of a USGS 7.5 minute topographic quad. 1027 blocks systematically dispersed over Florida so that their centers are 7.5 minutes apart in latitude and longitude were chosen as priority blocks.

Coordination of coverage
9 regional coordinators will recruit county coordinators for most of the 67 counties.

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 in a block during its breeding season with no evidence of breeding. Not in suitable nesting habitat. Includes species such as vultures or raptors flying over, or a colonial nesting species not at a nesting colony.
PO Category - possible breeding evidence
SH Species (male or female) observed in suitable nesting habitat during safe dates.
SM Singing male present, or breeding calls (or drumming by woodpeckers) heard, in suitable nesting habitat in breeding season during safe dates.
PR Category - probable breeding evidence
S 7 or more territorial males observed only once in the breeding season.
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.
V Visiting probable nest site, or nest building by wrens or woodpeckers.
A Agitated behavior or anxiety calls from adult.
B Brood patch or cloacal protuberance.
CO Category - confirmed evidence of breeding
NB Nest building or excavation of nest cavity by any species except wrens and woodpeckers, or adults carrying nest material excluding far-ranging species.
DD Distraction display or injury feigning, or attacking humans or other predators.
NU Used nests or egg shells found. Must be carefully identified, if they are to be accepted.
FE Female with egg in oviduct. (For banders.)
FY Recently fledged young or downy young incapable of sustained flight.
CF Carrying food for young (not carrying food to a perch for its own consumption).
