Biologists have linked nest attendance and nestling feeding rates to nest predation risk, and advances in video nest monitoring allow continuous data collection to provide this information. We documented attendance patterns at western meadowlark nests, identified nest predators, and assessed the effects of our camera system on nest survival in the Nebraska Sandhills.Meadowlark females were absent, as a proportion of time, 0.24 during the day and 0.04 during the night throughout incubation, and 0.66 and 0.13, respectively, during the nestling stage. We found no evidence of negative effects of nest cameras on estimates of daily nest survival. The attendance patterns we observed may contribute to temporal trends observed in daily nest survival of grassland birds.
