Fate Of Captive-Reared And Released Mallards On Eastern Long Island, New York, Carrie E. Osborne, Bryan L. Swift, Guy A. Baldassarre
Human–Wildlife Interactions
We studied captive-reared mallards (Anas platyrhynchos; CRMs) released on eastern Long Island, New York, in 2006 to 2007 and 2007 to 2008 to determine: (1) survival rates of CRMs; (2) contribution to hunter harvest; (3) local movements; and (4) pair status, reproductive behavior, and production of CRMs. We banded and released 100 CRMs in November 2006 of which 20 were radio-marked. In November 2007, we banded and released 299 CRMs of which 60 were radio-marked. We used Program MARK to determine weekly survival estimates (0.53 to 1.00) up to 24 weeks after release; cumulative survival from November to …

Movements, Habitat Selection, Associations, And Survival Of Giant Canada Goose Broods In Central Tennessee, Eric M. Dunton, Daniel L. Combs
Human–Wildlife Interactions
The brood-rearing period in giant Canada geese (Branta canadensis maxima) is one of the least-studied areas of goose ecology. We monitored 32 broods in Putnam County, Tennessee, from the time of hatching through fledging (i.e., when the goslings gained the ability to fly) and from fledging until broods left the brood-rearing areas during the spring and summer of 2003. We conducted a fixed-kernel, home-range analysis for each brood using the Animal Movement Extension in ArcView® 3.3 GIS (ESRI, Redlands, Calif.) software and calculated 95% and 50% utilization distributions (UD) for each brood. We classified 25 broods as sedentary …
