Big Bird: A global dataset of birds in drone imagery annotated to species level
Drones are a valuable tool for surveying birds, but manually detecting and identifying birds in drone images is costly. We assembled a diverse dataset of 23 865 images of birds captured with 21 different drones across 11 countries. We labelled 4824 of these images, detailing the location, species, posture category, age category, and sex of 49 990 birds

Offshore wind farm avoidance by a discard‐feeding seabird is independent of local fishing activity
Fishing is not allowed within wind farms; therefore, discard‐feeding seabirds may appear to avoid wind farm areas. We found that most Lesser Black‐backed Gulls avoided the wind farm area, but not each individual in each period. Avoidance of the wind farm was not driven by fishing exclusion within its perimeter.

Steep declines of colonial wading birds in northeastern North America's largest breeding population
This study analyzed 22 years of complete nest census data for colonial wading birds in New York–New Jersey Harbor, the largest breeding population in the northeastern United States. Over this period, the total wading bird population decreased by 27%, a rate exceeding average long‐term declines across North American birds.

The Pinnated Bittern Botaurus pinnatus (Ardeidae) is a widely distributed Neotropical wading bird whose distribution and seasonal status remain poorly resolved. Discrepancies among published literature, citizen science records and the range currently assumed by BirdLife International indicate that both its geographical distribution and migratory ...

The pectoralis muscle orientation as an indicator of the modes of wing‐propelled locomotion in birds
The pectoralis orientation of birds was consistent with the orientation of the aerodynamic force acting on the wing, varying by wing‐propelled locomotion (WPL) mode. The skeletal morphology unique to each WPL mode, related to the origin/insertion of the pectoralis, may be associated with these functional demands of pectoralis orientation.
