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 …
Selection Of Pathways To Foraging Sites In Crop Fields By Flightless Canada Geese, Troy M. Radtke, Charles D. Dieter
Selection Of Pathways To Foraging Sites In Crop Fields By Flightless Canada Geese, Troy M. Radtke, Charles D. Dieter
Human–Wildlife Interactions
Geese, especially when they are flightless, can cause significant crop damage. We determined the effects of shoreline characteristics on foraging site selection by flightless Canada geese (Branta canadensis) in South Dakota. Distance from edge of crop field to wetland and visual obstruction by vegetation were important determinants of pathway selection by geese. Geese used crop fields for foraging that were closer to water than unused fields. Geese accessed those fields along pathways with less visual obstruction by vegetation than unused pathways. Our data suggest that this distance of crops to wetlands is the most important shoreline characteristic determining …

Nest-Site Selection And Nesting Ecology Of Giant Canada Geese In Central Tennessee, Jason S. Carbaugh, Daniel L. Combs, Eric M. Dunton
Human–Wildlife Interactions
Little information is available on giant Canada goose (Branta canadensis maxima) nest-site selection on isolated nesting ponds. We monitored 46 island and 72 shoreline nests in the Upper Cumberland (UC) region of central Tennessee during 2002 and 2003. We measured 6 habitat variables at nesting ponds and randomly-selected non-nesting ponds. We used logistic regression to determine which habitat variables were important in nest-site selection. Presence of an island was the most important variable, but it was excluded from the final analysis because of quasi-separation (i.e., geese nested on all known islands in the study area). Geese that nested …
