Factors affecting survival of northern Pintail ducklings in Alberta

Article Abstract:

The brood-rearing success of female Northern Pintail ducks has been considered, and duckling survival was related to maternal and environmental attributes. The study area was the Kitsim Ducks Unlimited Project land near Brooks, Alberta, Canada. Duckling survival on Kitsim was found to be higher than reported for pintails in Alaska, with early hatched young tending to survive better.
