Review Of Curassows And Related Birds, Paul A. Johnsgard

Papers in Ornithology

To contemplate the appearance of a new book dealing for the first time with an exhaustive coverage of an entire avian family is to evoke an excitement that is all too rare an occurrence for most ornithologists. This excitement is enhanced when the bird group is one of the least studied and yet, evolutionarily speaking, most significant of the galliform families, and when the authors are as well known and highly respected as Delacour and Amadon. Anticipation reaches its apogee when the contributing artists are as competent as Albert E. Gilbert, George M. Sutton, and David Reid-Henry. After reading the …

The Taxonomy And Relationships Of The Northern Swans, Paul A. Johnsgard

Paul Johnsgard Collection

The recent (1972) publication of the Wildfowl Trust's book The Swans has brought together an unprecedented array of information on all of the swans of the world, and makes it desirable to raise once again the question: how many species of northern swans are there, and what are their evolutionary relationships to one another? Delacour (1954) suggested the comprehensive vernacular name 'northern swans' to distinguish 'the various knobless white swans which breed in or near the Arctic parts of the northern hemisphere' from the Mute Swan (Cygnus olor) and the three southern hemisphere swans. The northern swans have …

Status Of The Wild Turkey In Southwestern Illinois In 1970, Robert Merle Cottingham

Masters Theses

Wild-trapped turkey were first released in southwestern Illinois in 1959. This, and subsequent releases have established a huntable population of wild turkey in the area. Until 1970, no evaluation of the status of the bird had been made. This study was conducted in June, July, August and September, 1970, to determine the distribution, productivity and relative abundance of the wild turkey in Alexander, Jackson, Union and Williamson Counties and to make recommendations for future management of the population. Information was supplied by rural mail carriers, Illinois Department of Conservation and U. S. Forest Service personnel and local residents together with …

Helminth Parasites Of Illinois Wild Turkeys, James W. Jackson

Masters Theses

Viscera from 69 wild turkeys (Meleagris gallopavo silvestris) collected from Jackson, Union and Alexander counties, Illinois, were examined for helminth and coccidian parasites. A total of eight species of parasites was found, all in the alimentary tract. The coccidian parasite Eimeria sp. was found in 9.6% of birds examined. The nematodes Heterakis gallinarum, Ascaridia galli and Ascaridia dissimilis were found in 13.2%, 27.9% and 48.5% respectively of all birds examined. Three species of cestodes, Raillietina williamsi, Metroliasthes lucida and Hymenolepis sp., were recovered from 41.1%, 27.9% and 1.4% respectively of birds examined. One species of trematode, …

How Many Cranes Make A Skyful?, Paul A. Johnsgard

Paul Johnsgard Collection

Every year thousands of lesser sandhills congregate along the Platte River in Nebraska on their spring migration northwards. Mainly because of local damage caused by the birds during their fall migration, they have been legally hunted since 1961. Can the population survive such persistent destruction?

One may ask the question “How many cranes are enough?” This is perhaps analogous to the rhetorical question as to how many redwood trees are needed to make a viable forest; for a remnant crane population is not only unimpressive but also seemingly does not survive or reproduce well, judging from population trends in the …

Natural And Unnatural Selection In A Wild Goose, Paul A. Johnsgard

Papers in Ornithology

Blue goose and snow goose color phases enable the species to reproduce efficiently in the harsh Canadian climate. But hunters, more eager than sporting, are upsetting this finely tuned pattern of survival.
