Time spent foraging (and in other activities), rate of pecking at food items and length of foraging and nonforaging periods were studied in cackling Canada goose (Branta canadensis minima) goslings during brood-rearing on the Yukon-Kuskokwim Delta, Alaska in 1978 and 1979. Brood density on the study area was twice as high in 1978 (23 broods) as in 1979 (12(More)
We compared the observed daily time allocation of cackling geese (Branta canadensis minima) during spring with that predicted from estimates of daily energy requirements and measurements of apparent metabolizable energy (AME) and intake rates. Cackling geese gained substantial energy and protein reserves at staging areas in California before migration to(More)
