  • 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.

  • Hooded Merganser
    Mergansers Order Anseriformes Family Anatinae Subfamily Mergini The Mergansers are grouped among the diving ducks but belong to their own subfamily. They are long, slender-bodied diving ducks with long, narrow saw-edged (or serrated - below, center) bills, which help them grip and hold on to fish. Often called “sawbirds,” mergansers are known for their colorful plumage and habits of flying fast & close to the water’s surface. Most species have crests on their heads, which they can hold up or down at will (top photos and below left). In flight, their head, bill, body and tail are held in a straight horizontal line. Mergansers prey on fish, fish eggs and other aquatic animals. The hooded merganser (Lod- phodytes cucullatus) - top right -lives among reeds in Pennsylvania’s swampy, woodland habi- tats using a tree cavity near a pond, lake, river or stream. They will also use a man-made nesting box placed in the proper habitat. The common merganser (Mergus merganser) - top left) needs a wilder, less inhabited site in order to nest. They too are cavity-nesters, but will also nest in a rock pile or even a hole in a stream bank (like a kingfisher). Red-breasted merganser (Mergus serrator) females build her nests in thick vegetation on the ground - though she nests in Canada and Alaska, not in Pennsylvania. But they can be seen on our open rivers during mi- gration. Merganser ducklings from various nests are often grouped to- gether and looked after by a single female..

  • 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.
