BRIEF DESCRIPTION OF DATA FILE: This file contains census data on salt marsh birds using 100 m radius counting circles for the Parker River National Wildlife Refuge
KEYWORDS: salt marsh birds, Parker River National Wildlife Refuge
SITE TYPE: Higher Trophic Levels
RESEARCH LOCATION: Counting circles located on salt marsh habitats adjacent to Plum Island Sound and within the boundaries of the Parker River National Wildlife Refuge.
EXPERIMENTAL DESIGN AND METHODS: Standard breeding bird censuses with 100 m radius counting circles. Observing periods divided into 0-3 min, 3-5 min, and 5-10 minutes for comparison with other censuses. For 3-5 min period, only additional birds not recorded in the 0-3 period are recorded. For 5-10 min period, only additional birds not recorded in the 0-5 min period are recorded. Birds recorded either visually or by sound. Counting circle boundaries set a minimum of 200 m from each other. Observer distinguished between birds within 50 m of the center point, birds from 50-100 m, and those beyond 100 m. Counts carried out from late May through August over a three-year period. Placement of circles within vegetated salt marsh habitat.
NOTES AND COMMENTS:
Temperature inconsistently recorded
VARIABLE DESCRIPTION:
Census Unit – Code name of individual counting circles
xUTM – the X coordinate location of the center of the census unit in UTM
yUTM – the Y coordinate location of the center of the census unit in UTM
Date – The date of the survey (DD-MMM-YYYY)
Time – Time in EST
Observer – Name of person making
observations
Temp – Temperature at beginning of
survey (oF). A blank space
indicates that no reading was taken
% Cloud – Estimation of the percent

Scientific Name – an abbreviation of
the scientific name of the bird species.
First two letters of genus in upper case, first five letters of species
name in lower case
Common Name – full common name of
the bird species
0-3 <50m – Number of individuals
of that species seen within the 50 m counting circle during the first 3 minutes
of entering the circle
3-5 <50m – Additional individuals
observed or heard from 3-5 minutes within the 50 m radius counting circle. These were individuals not seen or heard in
the first 0-3 minutes.
5-10<50m - Additional individuals
observed or heard from 5-10 minutes within the 50 m radius counting circle.
These were individuals not seen or heard in the first 0-5 minutes.
0-3 50-100m - Number of individuals
of that species seen or heard between 50 and 100 m within counting circle
during the first 3 minutes of entering the circle.
3-5 50-100m – Additional individuals
observed or heard from 3-5 minutes from 50- 100 m radius within counting
circle. These were individuals not seen or heard in the first 0-3 minutes.
5-10 50-100m - Additional
individuals observed or heard from 5-10 minutes from 50- 100 m radius within
counting circle. These were individuals not seen or heard in the first 0-5
minutes.
0-3 >100m – Number of individuals
of that species seen outside the 50 m counting circle within the first 3
minutes of entering the circle
3-5 >100m – Additional
individuals observed or heard from 3-5 minutes outside the 100 m radius
counting circle. These were individuals not seen or heard in the first 0-3
minutes.
5-10 >100m - Additional
individuals observed or heard from 5-10 minutes outside the 100 m radius
counting circle. These were individuals not seen or heard in the first 0-5
minutes.
