BODY WEIGHT AND FEATHER GROWTH OF MALE BARROW’S GOLDENEYE DURING WING MOLT
Barrows Goldeneye (Bucephala islandica) Science Article 4 abstract We studied the timing, duration, and rate of wing molt of male Barrow’s Goldeneye (Bucephala islandica). The mean daily change in primary feather length was 2.6%, which is consistent with rates reported for other waterfowl species. The mean length of the flightless period was 31 days (range: […]
TRACING NUTRIENT ALLOCATION TO REPRODUCTION INBARROW’S GOLDENEYE
