Growth and Development of Prefledging Canada Geese and Lesser Snow Geese: Ecological Adaptation or Physiological Constraint?
Abstract Neonate, gosling, and adult Canada Geese (Branta canadensis interior) and Lesser Snow Geese (Chen caerulescens caerulescens) were collected to evaluate if growth rates and developmental patterns differed interspecifically and to determine if such differences were better explained by physiol...
