Local Control Of Crows By Trapping, C J. Woodbury

Journal of the Department of Agriculture, Western Australia, Series 4

THE common crow seen frequently around farms in the South-West is the raven (Corvus coronoides) whilst the pest of pastoral areas is the true Australian crow (Corvus cecilae).

Farmers and pastoralists, although recognising the importance of these birds as scavengers and destroyers of insects, particularly grasshoppers, sometimes for one reason or another, wish to reduce their numbers over a localised area.

Baiting with phosphorus has been used in the past, but the purpose of this article is to describe and illustrate a type of trap which has become universally known as the "Australian Crow Trap."

Control Of The Emu, C D. Gooding, J. L. Long

Journal of the Department of Agriculture, Western Australia, Series 4

Vermin research officers C. D. GOODING and J. L LONG give the latest recommendations for control of the emu, based on a series of observations and poisoning experiments in the northern wheatbelt.

Correspondence About "Evolutionary Relationships Among The North American Mallards", Allan R. Phillips, Paul A. Johnsgard

Papers in Ornithology

The confusing leading article of the 1961 Auk calls for comment. Despite his title, "Evolutionary Relationships among the North American Mallards," the author discusses primarily geographic distributions, population sizes, egg-white proteins( !), and certain behavioral patterns. Maps are based on ". . . the literature, personal communications, and the major United States collections," " . and from additional sight and specimen records available to me"; yet only two museums other than Cornell University are mentioned in the acknowledgments. These maps show many records of platyrhynchos far to the south; sometimes (Figure 1) the reader must search hard for any hint …

The Taxonomy Of The Anatidae—A Behavioural Analysis, Paul A. Johnsgard

Paul Johnsgard Collection

Delacour & Mayr's (1945) classic revision of the Anatidae took waterfowl behaviour into account to a much larger degree than had any previous classifications of the group. However, their utilization of behaviour was primarily at the tribal and generic levels, and no real attempt was made to use behaviour for determining intrageneric relationships. Thus far only Lorenz (1941, 1951-1953) has seriously attempteq this with waterfowl, and his analysis of the relationships within the genus Anas (sensu Delacour & Mayr) has provided a remarkable insight into the evolution of this group. I have attempted to expand Lorenz's behavioural delineation of relationships …

Wintering Distribution Changes In Mallards And Black Ducks, Paul A. Johnsgard

Papers in Ornithology

Through the use of data compiled by the Audubon Society's annual Christmas Counts, an attempt has been made to trace the distributional changes of wintering Mallards and Black Ducks in the eastern states from 1900 to the present. During this period the Black Duck has increased relative to the Mallard in few if any states (the Great Lakes region), whereas the Mallard has increased nearly everywhere else (except in the extreme northeast), particularly in the southern coastal states. Deforestation and changes in land use are sug- gested as probable reasons for this trend, which is not likely to be reversed.

Evolutionary Relationships Among The North American Mallards, Paul A. Johnsgard

Papers in Ornithology

A comparative morphological, behavioral, and electrophoretic study was undertaken on six populations of North American mallards that are currently considered by the A.O.U. Check-list to comprise four species and two additional subspecies. These include Anas p. platyrhynchos, A. d. diaxi, A. d. novimexicana, A. f. fulvigula, A. f. maculosa, and A. rubripes. These forms are essentially allopatric in their breeding distributions, with the major exception of A. p. platyrhynchos and A. rubripes, which overlap throughout a several-hundred-mile zone in east-central United States.

Geographic ranges and population sizes are estimated, and evidence is presented to indicate that the …

Pair-Formation Mechanisms In Anas (Anatidae) And Related Genera, Paul A. Johnsgard

Paul Johnsgard Collection

Although the" courtship" behaviour of waterfowl has attracted widespread interest and has been the subject of several major papers (e.g. Heinroth 1911, Lorenz 1951-1953), the actual means by which pairs are formed in most species of waterfowl remains unknown. We may conclude by inference that the females of most species of ducks must actively "select" their mates, for the elaborate male displays and plumage patterns present in the group can only be reconciled in terms of sexual selection. In addition, any observer of waterfowl will soon realize that it is the males which actively " court" the females, and that …
