Coates, P.S., Brussee, B.E., Hothem, R.L., Howe, K.H., and Casazza, M.L., 2015, The Effects of Heterospecifics and Climatic Conditions on Incubation Behavior within a Mixed-Species Colony: U.S. Geological Survey data release,


This U.S. Geological Survey Data Release contains the data and metadata associated with the journal article. Parental incubation behavior largely influences nest survival, a critical demographic process in avian population dynamics, and behaviors vary across species with different life history breeding strategies. Although research has identified nest survival advantages of mixing colonies, behavioral mechanisms that might explain these effects is largely lacking. We examined parental incubation behavior using video-monitoring techniques on Alcatraz Island, California, of black-crowned night-heron Nycticorax nycticorax (hereinafter, night-heron) in a mixed-species colony with California gulls Larus californicus and western gulls L. [...]

The principle objective of this study was to explain variation in incubation behavior of night-herons by investigating effects of heterospecifics, climatic conditions, within-season temporal effects, and other ecological factors.
