The height of the cormorant nests above the ground varied from 2.2 to 5.5 m. The water depth varied from 1.0 m at the beginning of the laying period to 3.0 m by the middle of the breeding season. Mean egg measurements were 46.5 ? 30.6 mm. Mean clutch size was 5.3 eggs (range: 2 to 8); clutches of 5 and 6 were the most common. Almost 77\% of the 867 eggs laid in 165 nests observed over three years hatched. Survival of chicks to three weeks of age was 69\% of the eggs laid and 89.8\% of eggs hatched.

However, foraging success there was generally lower than in other habitats; a considerable part of the Little Egret population simply used this habitat type without feeding possibly due to manmade habitat alterations that took place during the study period. Saltmarshes were an important habitat: Little Egrets foraged exclusively there in March, and in the pre- and post-breeding periods foraging success was generally higher than in other freshwater habitats. In rice fields, Little Egrets had a generally greater foraging success than in the other habitats in two of the three study years.

Both species nested above the middle of tamarisks and alders. Nest density varied each year from 333.3 nests/ha to 646.2 nests/ha for Blackcrowned Night-Herons and 291.7 nests/ha to 421.5 nests/ha for Little Egrets. Black-crowned Night-Herons started to breed earlier than Little Egrets, also placing their nests higher (mean nest height: 4.21 {\textpm} SD of 0.80 m and 3.54 {\textpm} SD of 0.71 m for Black-crowned Night-Herons and Little Egrets, respectively). The nearest neighbors were conspecifics for Black-crowned Night-Herons and heterospecifics (Black-crowned Night-Herons) for Little Egrets. The mean distance of the nearest neighbor was similar in both species (1.02 {\textpm} SD of 0.46 m and 1.11 {\textpm} SD of 0.37 m for Black-crowned Night-Herons and Little Egrets, respectively). In contrast to late-nesting Little Egrets that located their nests lower, Black-crowned Night-Herons maintained a constant nest distance from the ground. The mean clutch size (3.40 {\textpm} SD of 0.60 and 4.32 {\textpm} SD of 0.81 for Black-crowned Night-Herons and Little Egrets, respectively) and the mean chick survival per nest (2.48 {\textpm} SD of 0.95 and 2.53 {\textpm} SD of 1.28 for Black-crowned Night-Herons and Little Egrets, respectively) of both species varied among the study years. No variation was observed in the means of clutch size and chick survival per nest of Black-crowned Night-Herons among the 3 sub-periods of the breeding season. Little Egret clutch size and mean number of eggs hatched was smaller in late nesters, but no difference was observed in chick survival per nest between early and late nesters.

Rice fields offered better conditions to foraging herons than natural habitats in northwestern and northeastern Italy where the number of feeding herons, food intake rates, and prey abundance in rice fields were higher. The proportion of the food resources obtained by herons from the agricultural habitats, rice fields and small irrigation canals was estimated using two independent methods. Six heron species acquired more than half of their food from rice fields in all the regions except the Rhone Delta where agricultural habitats offered less prey.

However, the rice fields that have supplanted them in some regions may be valuable habitats for waterbirds. We describe the use of rice fields by waders, gulls, terns, ducks and herons in Italy, Spain, France, Greece and Portugal where this cultivation is most prevalent in certain restricted areas. Rice field systems, including the irrigation canals, are used by a variety of waterbirds, primarily as feeding habitats, and to a lesser extent as breeding sites. The long duration of flooding allows waterbird use through winter in Spain and France; it is limited to spring in other regions. However, the heavy dependence of waterbirds on rice fields is hazardous, because rice cultivation is subject to suddenly changing agricultural practices. Threats include risk from pesticide contamination, changes in the management of rice cultures, the rapidly spreading practice of cultivating rice on dry fields, and from large-scale hydrological changes. We urge authorities to recognize the importance of rice fields for the conservation of Mediterranean waterbirds and propose that cultivation and bird conservation issues be addressed in a holistic fashion.}, keywords = {Aves, conservation, Mediterranean, Rice fields, waterbirds}, author = {Fasola, M. and Ruiz, X.} } @article {5344, title = {Effect of water level fluctuations on wading bird foraging habitat use at an irrigation reservoir, Lake Kerkini, Greece}, journal = {Colonial WaterbirdsColonial Waterbirds}, volume = {20}, number = {2}, year = {1997}, note = {TY - JOURCited By (since 1996): 5Export Date: 7 September 2006Source: ScopusReferences: Babalonas, D., Papastergiadou, E., The the water fern Salvinia natans (L.)

We determined the effect of water level fluctuations on the area of available Ciconiiformes{\textquoteright} foraging habitat at low, intermediate and high lake stages. Log-linear analysis assessed the changes in the patterns of foraging habitat use by Great Egrets, Little Egrets and Grey Herons in response to the interactions of foraging habitat type and lake stage. At low lake stage Ciconiiformes mainly foraged in non-vegetated habitats or in lacustrine and palustrine habitats with submerged vegetation, while at intermediate lake stages they used palustrine habitats with emergent or submerged vegetation. At high lake stage birds shifted to riverine habitats that constituted the main available foraging grounds. The coexistence of three wetland systems enhances habitat heterogeneity at Lake Kerkini and enables large heron populations to thrive, despite the relatively small foraging area compared to other Mediterranean wetlands. Only Great Egrets seem to face constraints related to the limited availability of marshes - habitats linked to the species feeding and nesting requirements - during the breeding period.}, keywords = {Ardea alba, Ardea cinerea, Aves, Ciconiiformes, Egretta garzetta, Foraging habitat, Greece, Impoundment, Lake Kerkini, Wading birds}, author = {Dimalexis, A. and Pyrovetsi, M.} } @article {5345, title = {Foraging ecology of the Grey Heron (Ardea cinerea), Great Egret (Ardea alba) and Little Egret (Egretta garzetta) in response to habitat, at 2 Greek wetlands}, journal = {Colonial WaterbirdsColonial Waterbirds}, volume = {20}, number = {2}, year = {1997}, note = {TY - JOURCited By (since 1996): 6Export Date: 7 September 2006Source: ScopusReferences: Cezilly, F., Boy, V., Age related differences in foraging Little Egrets, Egretta garzetta (1988) Colonial Waterbirds, 11, pp. 100-106; Cezilly, E., Boy, V., Hafner, H., Group foraging in Little Egrets (Egretta garzetta): From field evidence to experimental investigation (1990) Behavioural Processes, 21, pp. 69-80; Draulans, D., The effect of prey density on foraging behaviour and success of adult and first-year Grey Herons (Ardea cinerea) (1987) Journal of Animal Ecology, 56, pp. 479-493; Draulans, D., Van Vessem, J., Symons, F., Multivariate analysis of factors affecting foraging success of Grey Herons (Ardea cinerea) at a fish-farm in winter (1986) Annals of the Belgian Zoological Society, 116, pp. 247-261; Erwin, R.M., Feeding behavior and ecology of colonial waterbirds: A synthesis and concluding comments (1983) Colonial Waterbirds, 6, pp. 73-82; Erwin, R.M., Hafner, H., Dugan, P., Differences in the feeding behavior of Little Egrets (Egretta garzetta) in two habitats in the Camargue, France (1985) Wilson Bulletin, 97, pp. 534-538; Fasola, M., Resource use of foraging herons in agricultural and nonagricultural habitats in Italy (1986) Colonial Waterbirds, 9, pp. 139-148; Fasola, M., Rosa, P., Canova, L., The diets of Squacco Herons, Little Egrets, Night, Purple and Grey Herons in their Italian breeding range (1993) Revue Ecologie (Terre et Vie), 48, pp. 35-47; Hafner, H., (1977) Contribution a l{\textquoteright}Etude Ecologique de Quatre Especes de Herons (Egretta G.

Parameters of foraging tactics - such as strike rate, foraging effort expended per min and effort expended per strike - as well as parameters of foraging efficiency - such as striking efficiency, captures per unit effort and biomass intake per unit effort - were analyzed in relation to habitat and lake. Each species adopted different tactics and achieved variable efficiencies in response to the particular lake, habitat conditions and prey characteristics. Little Egrets revealed the greatest plasticity in their foraging repertoire, especially with regard to their mobility and prey preference. Great Egrets and Grey Herons consumed larger amounts of biomass per unit effort than did Little Egrets, with Great Egrets achieving the highest striking efficiency.
