Box 154, Brooklyn, New South Wales, Australia 2083 Received: I I Augusr 2003 A colony of Great Egrets Ardea alba and Nankeen Night Herons Nycticorax caledonicus has existed at the Perth Zoo, Western Australia for over 25 years. The colony of egrets is one of very few in the region and hence is significant for the conservation and management of Great Egrets in Western Australia. From 1996 to 1998, surveys were conducted to determine the number of breeding pairs, clutch size, breeding success, and nest site selection of birds in the colony. Most observations were ground based, but a 30-metre cherry picker was used to inspect nests and determine clutch size. One hundred and thirty night heron and 49 egret nests were found in 1996; 92 night heron and 41 egret nests in 1997; and, 153 night heron and 36 egret nests in 1998. Nesting commenced in September, with peak numbers in early November. Both species nested in tall trees well above zoo visitors and animals. Egrets nested only in pines, whereas night herons nested mainly in figs. Great Egrets had an average clutch size of 2.6-2.7 by early November compared with a clutch of 1.6-1.8 for Nankeen Night Herons. -

Parasitic Nematodes of Pool Frog (Pelophylax Lessonae) in the Volga Basin

ABSTRACT Objetive. Present a modern review of the nematodes fauna of the pool frog Pelophylax lessonae (Camerano, 1882) from Volga basin populations on the basis of our own research and literature sources analysis. Materials and methods. Present work consolidates data from different helminthological works over the past 80 years, supported by our own research results. During the period from 1936 to 2016 different authors examined 1460 specimens of pool frog, using the method of full helminthological autopsy, from 13 regions of the Volga basin. Results. In total 9 nematodes species were recorded. Nematode Icosiella neglecta found for the first time in the studied host from the territory of Russia and Volga basin. Three species appeared to be more widespread: Oswaldocruzia filiformis, Cosmocerca ornata and Icosiella neglecta. For each helminth species the following information included: systematic position, areas of detection, localization, biology, list of definitive hosts, the level of host-specificity. Conclusions. Nematodes of pool frog, excluding I. neglecta, belong to the group of soil-transmitted helminthes (geohelminth) and parasitize in adult stages. Some species (O. filiformis, C. ornata, I. neglecta) are widespread in the host range. -

Postbreeding Movements of the Dark Gopher Frog, Rana Sevosa Goin and Netting: Implications for Conservation and Management

We used radio telemetry to study the postbreeding movements of individuals of the only known population of dark gopher frogs, Rana sevosa, during two breeding seasons (1994 and 1996). Move- ments away from the pond were relatively short (< 300 m) and usually occurred within a two-day period after frogs initially exited the breeding pond. However, dispersal distances for some individuals may have been constrained by a recent clearcut on adjacent private property. Final recorded locations for all individ- uals were underground retreats associated with stump holes, root mounds of fallen trees, or mammal bur- rows in surrounding upland areas. When implementing a conservation plan for Rana sevosa and other amphibians with similar habitat utilization patterns, we recommend that a temstrial buffer zone of pro- tection include the aquatic breeding site and adjacent nonbreeding season habitat. When the habitat is fragmented, the buffer zone should include additional habitat to lessen edge effects and provide connec- tivity between critical habitats. -

However, according to recent studies, some anurans actively select subterranean environments on the basis of specific environmental features, and thus are able to inhabit these environments throughout the year. -

We attachedradio transmitterswith mortality sensorsto the oldest chicks (A-chicks) in 11 to 22 nestsof both speciesto monitor survival during the mid- to late nestlingperiod and into the postnestingdispersal period. For both species,we found significantdifferences between 1992and 1993in growth ratesand survival. Massgrowth ratesof chickswere higher in 1993 than in 1992for both species.Culmen-length growth ratesvaried significantlydue to year-colonyeffects for night-herons,but only for hatching order for egrets.Differences in survival rates due to hatching order were found for the egrets in both years, but were found only in 1992for night-herons.As with massgrowth rates, survival of chickswas higher in 1993 than 1992.Survival of radio-markedA-chicks did not differ between speciesor years for the period from hatchingto fledging or from fledging through the end of the study (ca. two monthspostfledging). Survival ranged from 0.80 to 1.00from the time radio transmitters were attached(ca. two weeksof age) until dispersalage (53-55 daysfor egrets;55-60 days for night-herons).After birds left the colony,survival rateswere lower during the next 40 to 55 days,ranging from 0.25 to 0.60. -

Heron, Black-Crowned Night
142 Herons and Bitterns — Family Ardeidae Black-crowned Night-Heron Nycticorax nycticorax The Black-crowned Night-Heron spends much of the day resting quietly in marshes or trees, then at dusk flies off to forage, broadcasting a startlingly loud “quock!” In San Diego County it is locally common year round, both along the coast and at lakes and marshes inland. From 1997 to 2001 there were seven substantial colonies in the county, most mixed with other species of herons. Isolated pairs or small colo- nies also contribute to the population, to an unknown degree. Breeding distribution: Like the Great Blue, the Black- crowned Night-Heron nests mainly in colonies, often in mixed heronies.
