The performance of drones and artificial intelligence for monitoring sage‐grouse at leks
Accurately monitoring sage‐grouse populations is critical for conservation, yet traditional ground‐based visual surveys face challenges in scalability and consistency, prompting the exploration of innovative drone‐based methodologies enhanced by artificial intelligence.

Design considerations for breeding waterfowl surveys
This study evaluated how different survey designs affect the accuracy and precision of breeding waterfowl population estimates in Iowa's Prairie Pothole Region. Using aerial survey data from 2016–2018, we found that conducting at least 2 visits per season reduced bias in pair estimates, particularly for wood ducks and blue‐winged teal, while mallard ...

Abundance estimates of eastern black rails in southeastern Colorado
This study estimated eastern black rail (Laterallus jamaicensis jamaicensis) detection, occupancy, and abundance in southeastern Colorado. We found detection probability increased later in the season and later at night but decreased with ambient noise. Occupancy increased with residual vegetation height and detection of Virginia rail (Rallus limicola).
