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. -

THE ALEUTIAN CACKLING GOOSE in ARIZONA DAVID VANDER PLUYM, 2841 Mcculloch Blvd
THE ALEUTIAN CACKLING GOOSE IN ARIZONA DAVID VANDER PLUYM, 2841 McCulloch Blvd. N #1, Lake Havasu City, Arizona, 86403; [email protected] ABSTRACT: There is little published information about the occurrence of the Aleutian Cackling Goose (Branta hutchinsii leucopareia) in Arizona. Formerly listed as endangered by the U.S. Fish and Wildlife Service, this subspecies has rebounded, leading to an increase in numbers occurring outside its core range, including Arizona. Since the first in 1975, at least 24 well-founded records for Arizona have accumulated, one supported by a specimen, two by band recoveries, and 20 by diagnostic photo- graphs. Since 2013 the Aleutian Cackling Goose has occurred in Arizona annually between November and February. It is most frequent along the Colorado River, but records extend as far east as Willcox, Cochise County. The taxonomy of the “white-cheeked” geese is complex and debated. Currently, most treatments list 11 or 12 taxa in this group, and Banks et al. (2004) split them into two species: the Cackling Goose (Branta hutchinsii) and the Canada Goose (B. canadensis). Taxonomists generally recognize four extant subspecies of the Cackling Goose: hutchinsii, taverneri, minima, and leucopareia (Aleutian Cackling Goose). The now extinct population formerly breeding in the Commander and Kuril islands in Russia and wintering south to Japan has been considered a separate subspecies, asiatica (Banks et al. 2004), or a western population of leucopareia (e.g., Baldassarre 2014, Reeber 2015). Birds discovered breeding on the Semidi Islands in 1979 and wintering in coastal Oregon are phenotypically interme- diate between other populations of leucopareia and taverneri (Hatch and Hatch 1983) and do differ genetically from other populations of leucopareia, but they likely represent distinct populations of leucopareia rather than a valid separate taxon (Pierson et al. -

Cackling Geese in the East
Cackling Geese in the East Since 2004, when Cackling Geese were formally split from Canada Geese, birders have been keeping an eye out for small-bodied and short-billed geese, termed Cackling Geese, mixed in with “typical” large-bodied, wedge-headed Canada Geese. This ID challenge is very much like a birders version of “Where’s Waldo?”An excellent overview of this split was provided by OMNR waterfowl expert, Ken Abraham, in the winter of 2005. Here’s the link: http://www.ofo.ca/site/page/view/articles.cacklinggoose. I will attempt to make this discussion as clear, digestible, and casual as possible, but if anything is unclear, please email me at [email protected] and I would be happy to go over material. Below I provide an identification overview of “Richardson’s” (hutchinsii) Cackling Geese, Myth Busting, and Quiz photos. ______________________________________________________________________________ “Richardson’s” (hutchinsii) Cackling Geese Figure 1: Ontario’s Cackling Geese: an example of five “classic” hutchinsii Cackling Geese. Note the diminutive size overall; steep forehead; proportionally small head with “blocky” shape in most postures; peaked rear to crown; relatively thick and short bill (variable and may sometimes show a pronounced droop nearest the tip; lending to a Roman’s Nose look); show short and stubby neck (esp. in relaxed posture); small, compact body; pale emarginations often seen but not always; breast averages paler than Canada Geese but this is not the case on some birds, esp. juveniles.
