Time allocation by greater white-fronted geese: influence of diet, energy reserves and predation
Article Abstract:
The activity budget of wintering greater white-fronted geese in North America was determined. The geese spent less time feeding at foraging sites than the European variant. This is thought to be due to the North American dietof grains and potatoes, which provide a higher energy value than the European diet of grasses. Day length affected the time allocations for sleeping, alert and comfort activities rather than for feeding. Seasonal changes in the body mass of adult geese corresponded well to the proportion of feeding time. The geese were more alert and fed less during the hunting season.

Morphological differences in Pacific coast populations of Greater White-fronted Geese
Article Abstract:
A study of the morphological comparisons between three Pacific coast groups of Greater White-fronted Geese, employing a two-step discriminant function analysis, was suggestive of clinical changes in Greater White-fronted Geese populations, as reflected in the largeness in size of Tule Greater White-fronted Geese in comparison to Pacific Greater White-fronted Geese. Significant variations were noticed in Pacific Geese from Bristol Bay Lowlands when compared to those from Yukon-Kuskowim River Delta.

Behavior of Cackling Canada Geese during brood rearing
Article Abstract:
The behavior of the Cackling Canada Geese during brood rearing was studied using multivariate techniques to analyze the data gathered. Results reveal that the time used by adults and goslings to feed increased throughout the brood rearing years. It is concluded that forage quality and availability determines the amount of time spent feeding. Meanwhile, predation or disturbance affect the amount of time spent alert.
