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. -

Braz J Vet Parasitol 2020; 29(3): e003920. https://doi.org/10.1590/S1984-29612020049 Abstract The Neotropic cormorant Nannopterum (Phalacrocorax) brasilianus (Suliformes: Phalacrocoracidae) is widely distributed in Central and South America. In Chile, information about parasites for this species is limited to helminths and nematodes, and little is known about other parasite groups. This study documents the parasitic fauna present in 80 Neotropic cormorants’ carcasses collected from 2001 to 2008 in Antofagasta, Biobío, and Ñuble regions. Birds were externally inspected for ectoparasites and necropsies were performed to examine digestive and respiratory organs in search of endoparasites. -
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. -

A new breeding colony of Blue-footed Booby Sula nebouxii at Islote González, Archipelago Islas Desventuradas, Chile. Marine Ornithology 49: 189–192. We describe a new disjunct population of Blue-footed Booby Sula nebouxii at Islote González in the Islas Desventuradas archipelago. Though likely much larger, the population size at the time of our survey was a minimum of 16 breeding pairs. On 14–15 December 2020, two pairs of boobies with nestlings and four pairs with empty nests were found. Likely the species is a recent arrival to the archipelago, perhaps during one of the strong El Niño events between 1970 and 2001 (especially 1982/83, when the species was first recorded in Chile). Blue-footed Booby might also nest on different areas at San Félix Island and some smaller islets around the archipelago, where they would have no nesting-site competition from the larger Masked Booby S. dactylatra. Key words: Blue-footed Booby, Sula nebouxii, breeding, Islas Desventuradas, Chile INTRODUCTION northern coast between 21°54′S and 23°05′S (Guerra 1983).

Common Scoter: Species Information for Marine Special Protection Area Consultations
Natural England Technical Information Note TIN143 Common scoter: species information for marine Special Protection Area consultations The UK government has committed to identifying a network of Special Protection Areas (SPAs) in the marine environment by 2015. Natural England is responsible for recommending SPAs in English waters to Defra for classification. This and other related information notes have been prepared and will be available at meetings and online so that anyone who might be interested in why the SPA is being considered for classification can find out more about the birds that may be protected. For more information about the process for establishing marine SPAs see TIN120 Establishing Marine Special Protection Areas. Background northernmost Europe and Russia, including north and west Scotland. The Birds Directive (EC Directive on the conservation of wild birds (2009/147/EC) requires member states to identify SPAs for: rare or vulnerable bird species (as listed in Annex I of the Directive); and regularly occurring migratory bird species.

Species Limits Within the Genus Melanitta, the Scoters Martin Collinson, David T
A paper from the BOURC Taxonomic Sub-committee Species limits within the genus Melanitta, the scoters Martin Collinson, David T. Parkin,Alan G. Knox, George Sangster and Andreas J. Helbig Dan Powell ABSTRACT As part of its reassessment of the taxonomy of birds on the British List, the BOURC Taxonomic Sub-committee has assessed all six recognised taxa of scoters Melanitta against its previously published Species Guidelines (Helbig et al. 2002).We consider that, on the basis of evidence currently available, at least five species should be recognised: Common Scoter M. nigra, Black Scoter M. americana,Velvet Scoter M. fusca,White-winged Scoter M. deglandi and Surf Scoter M. perspicillata.The taxonomic status of the Asian subspecies of White-winged Scoter (stejnegeri) is uncertain, owing to insufficient information on several aspects of its morphology and behaviour. Provisionally, we suggest that it is best treated as conspecific with M. deglandi. © British Birds 99 • April 2006 • 183–201 183 Species limits within the genus Melanitta Introduction regarded as separate species (BOU 1883, 1915; Six taxa of scoters Melanitta are generally recog- Dwight 1914). nised within the seaduck tribe Mergini (Miller For brevity, these taxa will henceforth be 1916; Vaurie 1965; Cramp & Simmons 1977; referred to by their subspecific names, i.e. nigra table 1).
