Example of a photo from the USFWS fall aerial survey for Black Brant at Izembek Lagoon. Inset shows a closer view of four Black Brant (bottom) with a Cackling Goose (top) foraging on eelgrass.  We can use artificial intelligence to automate counting birds in each photo to develop population estimates.
