Diet and Habitat Use of Scoters Melanitta in the Western Palearctic - a Brief Overview
163 Diet and habitat use of scoters Melanitta in the Western Palearctic - a brief overview A. D. Fox Department of Wildlife Ecology and Biodiversity, National Environmental Research Institute, Kalø, Grenåvej 12, DK-8410 Rønde, Denmark. E-mail: tfo@dmu. dk If patterns of scoter distribution and abundance are to be understood, there is a need to know upon which prey items these birds feed, how they obtain these prey items and the habitats from which these food items are most easily harvested. Dietary studies and descriptions of habitats exploited by Common and Velvet Scoter in the non-breeding season are reviewed. The existing literature strongly suggests that, outside of the breeding season, these species forage mainly upon marine bivalve mol luscs (especially those less than 4cm long) that live on the surface or within the upper 3cm of clean, coarse, sandy substrates in waters less than 20m deep. Although there is a large energetic cost to diving, han dling and crushing such prey prior to digestion, such sedentary prey items often occur in very high densities, offering a locally abundant and predictable feeding resource. Since single species often dominate the diet, but dominant food items differ between feeding areas, it seem s likely that scoters simply take whatever prey is locally available in suffi cient abundance to fulfil nutritional needs. Large differences in docu mented prey size frequency distributions suggest that scoters may not select for specific prey size classes below an upper digestive limit. However, in the absence of any precise understanding of how scoters obtain their prey, nor any simultaneous studies of available benthic food abundance and size class distributions in scoter diets, it is not possible to confirm if differences simply reflect differences in profitability between different prey at different sites at different times of the year. -

Surf Scoter (Melanitta Perspicillata) Survey Stanley Park 1999-2000
Surf Scoter (Melanitta perspicillata) Survey Stanley Park 1999-2000 Prepared for: Daniel J. Catt, Wildlife Management Instructor British Columbia Institute of Technology Burnaby, BC & Dr. Sean Boyd, Research Biologist Canadian Wildlife Service Delta, BC Prepared by: Christine Williams, student Fish, Wildlife, Management Technology i Surf Scoter Survey, 1999-2000 Stanley Park _______________________________________________________________________________ British Columbia Institute of Technology Summary The Stanley Park Surf Scoter Survey was made possible through a co-operative arrangement between the Canadian Wildlife Service (CWS) and the British Columbia Institute of Technology (BCIT). The purpose of the study was to document the distribution and abundance of Surf Scoters (Melanitta perspicillata) observed along the Stanley Park foreshore in Vancouver, British Columbia from October 1999 to April 2000. An oil spill occurring on November 24, 1999 gave the survey another objective in the form of monitoring the effects of the spill on the distribution and abundance of Surf Scoter that utilise the foreshore of Stanley Park as wintering habitat. The Stanley Park foreshore sees large concentrations of wintering Surf Scoters from late October to April/May. The rocky shoreline, extensive mussels beds and combination of winds and tide make the foreshore an important habitat for Surf Scoters. Data were gathered and analysed from November 3, 1999 to April 15, 2000 to document the following: • Trends in the abundance and distribution of Surf Scoter throughout the wintering season • Observer variability in data collection • Tidal influence on Surf Scoter abundance and distribution • Sex ratios of Surf Scoter observed along the Stanley Park foreshore The results of the data analysis show the following: • Distribution: The Stanley Park foreshore was not utilised uniformly by Surf Scoters throughout the survey period. -

Waterfowl at Cold Bay, Alaska, with Notes on The
WATERFOWL AT COLD BAY, ALASKA, WITH NOTES ON THE DISPLAY OF THE BLACK SCOTER Frank McKinney Delta Waterfowl Research Station, Manitoba In 1958, it was my good fortune to spend April and May in the area of Cold Bay, near the tip of the Alaska Peninsula, studying waterfowl. For the waterfowl enthusiast, Alaska will always hold a special fascination. This is the home of the Emperor Goose (Anser canagicus), the Pacific Brant (Branta bernicla orientalis), the Spectacled Eider (Somateria fischeri) and Steller’s Eider (S. steli eri)—birds which relatively few ornithologists have seen in the wild but which are familiar to many through the writings of Brandt (1943), Bailey (1948) and most recently Fisher and Peterson (1955). The main object of this expedition was to investigate the spring behaviour of Steller’s Eider and of the Pacific Eider (Somateria mollissima v-nigra), and if possible to see something of King Eider and Spectacled Eider as well. I was particularly interested in the hostile and sexual behaviour which occurs before breeding and for this reason a centre for wintering birds was chosen in the belief that much of the pair-formation and related activities would occur before the birds moved to their breeding places. Cold Bay proved to be an ideal headquarters for these studies and during April I was able to watch large numbers of wintering Steller’s on Izembek Bay; in May I camped in the middle of a large colony of Pacific Eiders at Nelson Lagoon when breeding was about to begin. My observations on these two species are being incorporated in a detailed analysis of Eider displays, not yet completed. -
Waterfowl in Iowa, Overview
STATE OF IOWA 1977 WATERFOWL IN IOWA By JACK W MUSGROVE Director DIVISION OF MUSEUM AND ARCHIVES STATE HISTORICAL DEPARTMENT and MARY R MUSGROVE Illustrated by MAYNARD F REECE Printed for STATE CONSERVATION COMMISSION DES MOINES, IOWA Copyright 1943 Copyright 1947 Copyright 1953 Copyright 1961 Copyright 1977 Published by the STATE OF IOWA Des Moines Fifth Edition FOREWORD Since the origin of man the migratory flight of waterfowl has fired his imagination. Undoubtedly the hungry caveman, as he watched wave after wave of ducks and geese pass overhead, felt a thrill, and his dull brain questioned, “Whither and why?” The same age - old attraction each spring and fall turns thousands of faces skyward when flocks of Canada geese fly over. In historic times Iowa was the nesting ground of countless flocks of ducks, geese, and swans. Much of the marshland that was their home has been tiled and has disappeared under the corn planter. However, this state is still the summer home of many species, and restoration of various areas is annually increasing the number. Iowa is more important as a cafeteria for the ducks on their semiannual flights than as a nesting ground, and multitudes of them stop in this state to feed and grow fat on waste grain. The interest in waterfowl may be observed each spring during the blue and snow goose flight along the Missouri River, where thousands of spectators gather to watch the flight. There are many bird study clubs in the state with large memberships, as well as hundreds of unaffiliated ornithologists who spend much of their leisure time observing birds. -
