Pages : 72
Book Description
Special seasons for sea ducks began in the Atlantic Flyway in 1939 when 5 northeastern states were allowed 16-30 day extensions to their regular duck seasons. Initially, only scoters were legal game during the extensions. Over time, the season became more liberal and by 1972, 13 of the 17 states in the Flyway had special seasons that lasted 107 days and had bag limits of 7 eiders, oldsquaws, and scoters in the aggregate.

Behaviour and Ecology of Sea Ducks
Author: R. Ian Goudie
Publisher: Published for the Pacific Seabird Group by Canadian Wildlife Service
ISBN:
Category : Bird populations
Languages : en
Pages : 92
Book Description
Contains papers presented at a conference on sea ducks, a group of waterfowl exhibiting dramatic ornate plumages and life history strategies that are more akin to sea birds than to other species of ducks. Topics of the papers include: behaviour of harlequin ducks and scoters; productivity of breeding harlequin ducks; time budgets of surf scoter broods; habitat associations of nesting spectacled eiders; periodic non-breeding of Steller's eiders; philopatry of moulting harlequin ducks; foraging strategies and habitat use; distribution of scoters and eiders in the St. Lawrence estuary; and the eastern population of Barrow's goldeneye. Appendices include abstracts of nine other papers.

Ecology and Conservation of North American Sea Ducks
Author: Jean-Pierre L. Savard
Publisher: CRC Press
ISBN: 9781482248975
Category : Nature
Languages : en
Pages : 610
Book Description
The past decade has seen a huge increase in the interest and attention directed toward sea ducks, the Mergini tribe. This has been inspired, in large part, by the conservation concerns associated with numerical declines in several sea duck species and populations, as well as a growing appreciation for their interesting ecological attributes. Reflecting the considerable research recently conducted on this tribe, Ecology and Conservation of North American Sea Ducks examines the 15 extant species of sea ducks from North America. Chapters are organized conceptually to focus on, compare, and contrast the ecological attributes of the tribe. Experts provide in-depth treatments of a range of topics, including: Population dynamics and genetics Infectious diseases and parasites Breeding costs and cross-seasonal affects Contaminant burdens Foraging behavior and energetics Migration strategies, molt ecology, and habitat affinities and dynamics Breeding systems and reproductive behavior Harvest history The book presents a comprehensive synthesis of sea duck ecology, documents factors that have caused population declines of some species, and provides managers with measures to enhance recovery of depressed populations of sea ducks in North America. Capturing the current state of knowledge of this unique tribe, it provides a benchmark for where we are in conservation efforts and suggests future directions for researchers, managers, students, conservationists, and avian enthusiasts.
