Partial Depredations on Northern Bobwhite Nests

Show Summary Details

Preview

Nest predation resulting in only partial clutch loss is rarely studied in ground-nesting birds, despite predation often being the leading cause of nest failure. We identified 47 partially depredated northern bobwhitenests using continuous video monitoring. Most partial depredations were caused by rat snakes, kingsnakes, and fire ants. Parental outcomes of partial depredation included abandoning the nest or remaining with the nest either until hatching or failure from another predation event. Nests with fewer eggs remaining or those depredated early in incubation were more likely to be abandoned; juveniles appeared more likely to abandon than adults. Future nest-camera studies are necessary to confirm the relationships between cues and abandonment decisions.
