tween island size and resource base, 
trade, and the development of socio- 
economic systems in “Foragers and 
Farmers in the Western Torres Strait 
Islands: An Historical Analysis of Eco- 
nomic, Demographic, and Spatial Dif- 
ferentiation” ( Social and Ecological 
Systems, edited by P. Burnham and 
R.F. Ellen. London: Academic Press, 
1979). The first European contacts 
with Torres Strait Islanders are the 
focus of D.R. Moore’s Islanders and 
Aborigines at Cape York (Canberra: 
Australian Institute of Aboriginal 
Studies, 1979) and The Journal of 
John Sweatman, edited by J. Allen 
and P. Corris (Brisbane: University 
of Queensland Press, 1977). In “The 
Wind Caller” ( Natural History, 
March 1977, pp. 10-16), B. Nietsch- 
mann recalls some of the experiences 
he and his family had while learning 
about the Islanders’ knowledge of the 
environment. M. Lawrie’s Myths and 
Legends of Torres Strait (Brisbane: 
University of Queensland Press, 1970) 
is a nicely illustrated collection of 
many old tales. Australian novelist 
I.L. Idriess wrote several books based 
on a rather loose interpretation of Tor- 
res Strait cultural history, such as The 
Drums of Mer (Sydney: Angus and 
Robertson, 1933) and Wild White 
Man of Badu (Sydney: Angus and 
Robertson, 1950). Literature on 
- dugongs is slim, but has recently been 
increasing. A good, although dated, 
overview of dugong numbers and habi- 
tats can be found in G.C.L. Bertram 
and C.K.R. Bertram’s “The Modern 
Sirenia: Their Distribution and Sta- 
tus” ( Biological Journal of the Lin- 
naean Society, vol. 5, no. 4, 1973, 
pp. 297-338), which includes a section 
on dugongs in the Torres Strait. Zo- 
ologist G. Heinsohn has been studying 
dugongs since 1969; some of the re- 
sults of his research are summarized 
in “Sirens of Tropical Australia” 
( Australian Natural History, vol. 19, 
no. 4, 1978, p. 106-111). Heinsohn 
collaborated with P. Anderson on 
“The Status of the Dugong and 
Dugong Hunting in Australian Wa- 
ters: A Survey of Local Perceptions” 
( Biological Conservation, vol. 13, 
1978, pp. 13-26). Heinsohn, Ander- 
son, and H. Marsh wrote “Australian 
Dugong,” a good, illustrated review 
of habitats, behavior, and ecology 
( Oceans , May-June 1979, pp. 48-52). 
P. Anderson presents the results of 
his research at Shark Bay, Western 
Australia — one of the few places 
where dugongs are not hunted— in 
“Dugong Behavior: On Being a Ma- 
rine Mammalian Grazer” {The Biolo- 
gist, vol. 61, no. 4, 1980, pp. 1 13-44). 
R. Bustard’s Sea Turtles (New York: 
Taplinger, 1972) includes some dis- 
cussion of sea turtles in the Torres 
Strait. 
Purple Martins (p. 64) 
A complete guide to the purple mar- 
tin meant primarily for the layman, 
R.B. Layton’s The Purple Martin 
(Jackson: Nature Books Publishers, 
1971) contains information on the 
martin’s migration, what it eats, how 
it nests, and also gives hints on build- 
ing a martin house. A classic work 
on purple martins is R.W. Allen and 
M.M. Nice’s “A Study of the Breed- 
ing Biology of the Purple Martin” 
{American Midland Naturalist, vol. 
47, no. 3, 1952, pp. 606-65). The Na- 
ture Society News, formerly the Pur- 
ple Martin News, devotes most of its 
pages to purple martins. Published by 
the Nature Society, Purple Martin 
Junction, Griggsville, Illinois 62340, 
this newspaper regularly features a 
guide for new members entitled “How 
to Become a Purple Martin Land- 
lord.” Also published by this society 
is J.L. Wade’s popular paperback, now 
in its seventh printing. What You 
Should Know About the Purple Mar- 
tin (Griggsville: The Nature Society, 
1979). R.F. Johnston and J.W. Har- 
dy’s “Behavior of the Purple Martin” 
{Wilson Bulletin, vol. 74, September 
1962, pp. 243-62) is a detailed, de- 
scriptive account of reproductive, ag- 
gressive, and group behavior of purple 
martins.
