Transcript 2 sa eb=aa VOLUME XX, No. 11 Karch, 1972 PUBLISHED BY THE ORNITHOLOGY GROUP, OUTDOOR NATURE CLUB, HOUSTON, TEXAS GREAT BLUE HERON SURVEY from Raymond J. Fleetwood Currently, the Laboratory of Ornithology, Cornell University, Ithaca, N. Y. 14856. is engaged in a nation-wide survey of the Great Blue Heron. Since this speoies is at tho top of the aquatic food chain, it may well be an important indicator species, Tho first step will be to compile an inventory of heronries. To this end, I would like to recommend that anyone with knowledge on this" point write to the Laboratory of Ornithology. They have requested information which may be recent, or old, detailed, or sketchy, as long as the site is remembered wo11 enough to locate on a topographic map. When the inventory is completed, they would like for it to contain the exact locality of the heronry, a general description of the sito, and as much.history as possible, Thoy had hoped to have the program completed by winter, so that arrangements could be'made for census work in the 1972 breeding season. This aopoal is the result of an exciting recent development in using nost-record card programs as an international monitoring device. The basic premise is that breeding success of birds is an index of tho health of tho environment. This premise has. already been proven correct in the case of persistent pesticidos, but thoy consider that there are wider implications. If there is attrition of the ecosystem, owing to any of numerous causes, then one might expect that it would be impossible for birds to sustain as.high a production as previously. The nest-record card program, hopefully, will enable- these changes to be noted early, before catastrophic changes occur. Tho idea of international collaboration is being explored with the International Council for Bird Preservation and tho International Union for the Conservation of Nature and Natural resources (IUCN). A study conference has been arranged to see if the varicus European programs can agree on a common approach. Following this, there will be discussions with the IUCN on the organization of a world-wide monitoring system. ANNOUNCEMENT The following Jim Lane guides to bird finding are available now through the Ornithology Group; "A BIRDWATCHER'S GUIDE TO SOUTHEASTERN ARIZONA" "A BIRDER'S GUIDE TO SOUTHERN CALIFORNIA" ■ .. "A BIRDER'S GUDE TO THE RIO GRANDE VALLEY OF TEXAS" Kr. Lane has most generously given OG a 40$ commission on sales made by the group so both you and the Ornithology Group will bo beneficiaries when you purchase a book. Wo can highly recommend them, and appreciate the opportunity of making them available to birders. YELLOW RAIL TRIPS from Russell Clapper lellow Rails are now present in good numbers on the wet, salty prairie at Anahuac National wildlife Refuge. Tractor-drawn wagon rides with capacity of sixteen (16) people eaeh trip are scheduled as follows for each weekend I.arch 4, through April 30.
