Summary

This dataset includes tables summarizing image information and bird counts from the aerial digital images taken over open water at Izembek Lagoon in Alaska in fall 2017-2019. These summaries list one record per image and provide the camera parameters, latitude, longitude, altitude, and automated and manual counts representing the total number of birds in each taxon (brant, white-cheeked geese, emperor geese, gulls, and other birds) identified in the image. The original images (.JPG format) and annotations are provided in an accompanying USGS data release (Weiser et al. 2022).

Purpose

These data were collected to test a photographic survey design for monitoring the number of brant staging at Izembek Lagoon, Alaska, each fall. The photographic survey was tested as an option to potentially replace the traditional ocular aerial surveys that involve uncertainty around observer estimates of numbers of geese present. The count data were used to evaluate differences between automated and manual counts as well as to develop estimates of the total number of brant and white-cheeked geese on the lagoon during each annual survey period. Accuracy of the automated algorithm (assuming manual counts represent truth) can also be related to altitude or camera settings.
