Wildlife Observation Counter

How the Wildlife Observation Counter Works

The Wildlife Observation Counter records sightings by species, with one button per species and a timestamp for each sighting. New species can be added in the field.

1. Load a species list: Add the species you expect, such as Robin, Blackbird and Blue Tit.
2. Start the survey timer: Set a fixed survey length, such as 1 hour.
3. Tap per individual: Tap the species button once for each animal seen.
4. Add new species: Add a button for any unexpected species.

Wildlife Observation Counter Formula

The Wildlife Observation Counter species richness equals the number of species recorded, and relative abundance equals one species' count divided by all individuals counted.

Count(s)

Individuals of species s

Σ Count

All individuals counted

Example: A 1-hour survey records 42 house sparrows, 18 starlings, 9 robins and 6 blackbirds. Richness = 4 species. Sparrow abundance = 42 ÷ 75 = 56%.

Wildlife Observation Counter Reference Table

The Wildlife Observation Counter conversion table converts survey counts into sightings per hour and per square kilometer. The survey covers 0.5 km² (124 acres) in 2 hours.

About the Wildlife Observation Counter

A Wildlife Observation Counter is a field tally for counting animals by species during a survey. The tool replaces a notebook and pencil in point counts and transect walks.

Citizen science projects such as the RSPB Big Garden Birdwatch and the Audubon Christmas Bird Count rely on volunteers counting each species over a fixed period. Fixed time and area make counts comparable year to year.
