The vantage point count data provides counts of species during a vantage point survey. Please note that there may be multiple counts of a species during a vantage point survey as 3 counting periods were included in each vantage point survey.
Also note that a set of target species are included in every count period (please consult report for details of list by site), which will result on rows with zero observations during the period.
The columns included in the dataset are:
Date: Date of observations. Format is yyyy-mm-dd
VP Start: Start time of all vantage point observations (flight, count, disturbance)
VP End: End of all vantage point observations
Observer: Initial of the observer
VP: The Vnatage point location (see Vantage Point resource for location data)
Count: Identifies if count is for 1st, 2nd or 3rd count period within a vantage point survey
Count start: The start time of the count period
Count end: The end time of the count period
Tide: Observation of tie state (Rising, High, Falling, or Low)
Wind direction: Compass direction of wind
Wind Strength: Wind strength on beaufort scale
sea State: Sea state on Beaufort scale
Cloud cover: Cloud cover in okta
Weather: Weather condition Description (Fair, Snow/Hail, Rain, Drizzle)
Glare: Notes on glare that may affect observations
On structure: Indication if birds are roosting on structures/rocks
BTOSpeciesCode: 2 letter species code used by British Trust for Ornithology (see https://www.bto.org/sites/default/files/u10/downloads/taking-part/specie... )
Species Name: Common name of species
Scientific Name: Scientific (latin) name of species
Far L: Birds just outside sector left
L1-L4, R1-R4: Count of birds within observation sectors
Far R: Birds just outside sector right
The observation areas describes a 90 degree arch split in a left and right 45 degree arch. The number indicates distance from vantage point (0-250m, 250-500m, 500-1000m, and 1000-2000m). This R3 indicates the righthand observation sector with a distance beetween 500 and 1000m from the vantage point.
Please consult the report methodology section for detail on the observation areas and methodology.
