A comparison between the two age classes, as well as seasonal trends in adult data, indicated a negative association between prey size and foraging rates. Adult and juvenile foraging behavior did not vary significantly between morning and evening. Herons that moved faster also had higher pecking and capture rates, but a lower success ratio. Moving rate did not appear to be correlated with prey size. Herons moved at a slower rate along the edge of dense reed beds, probably in response to this habitat{\textquoteright}s physical structure.

A few Greeks and many foreign ornithologists, and in particular the Germans, contributed to the development of ornithology in our country during the 19(th) and 20(th) Centuries. The period following the decade of the 1980s however, seems to have been the most fruitful for this scientific domain in Greece. This review examines the interests of current ornithology in Greece and identifies any gaps in ornithological research. Surveys and biological studies with a conservational orientation were the main subjects for most of the 692 publications that appeared during the period 1980-2005. The majority of these works were published in international scientific journals, while the number of doctoral or other dissertations and papers on conference proceedings has constantly been increasing. Bird species of conservation interest such as Falco eleonorae, Pelecanus crispus, Egretta garzetta and Alectoris graeca were among the most studied. The majority of studies were carried out in wetlands, especially those of northern Greece, since waterbirds seem to be the most attractive bird group to ornithologists. Only in certain locations are mountainous and forested areas well studied, i.e. Crete and, Dadia. Although ornithology in Greece has made a big step forward during the last 26 years, there are still many unexplored fields. The challenge for future research must be directed towards filling the gaps in our knowledge on certain bird species and their habitats, organizing our efforts in order to predict avian responses to environmental pressure, and being prepared to deal with any changes that may occur in nature at large, both in Greece and worldwide.}, keywords = {Axios, DALMATIAN PELICANS, delta, eggs, EGRET-EGRETTA GARZETTA, Greece, habitat, HERON NYCTICORAX-NYCTICORAX, history of ornithology, Macedonia, ORGANOCHLORINE PESTICIDE-RESIDUES, ornithology, PELECANUS-CRISPUS, wetlands}, isbn = {1790-045X}, author = {Kazantzidis, S.} } @article {7552, title = {Foraging ecology and conservation of feeding habitats of Little Egrets (Egretta garzetta) in the Axios River Delta, Macedonia, Greece}, journal = {Colonial WaterbirdsColonial Waterbirds}, volume = {19}, number = {Suppl.1}, year = {1996}, note = {TY - JOURCited By (since 1996): 12Export Date: 8 September 2006Source: ScopusReferences: Erwin, R.M., Hafner, H., Dugan, P.J., 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., Feeding dispersion in the Night Heron Nycticorax nycticorax and Little Egret Egretta garzetta and the information centre hypothesis (1982) Bollettino Zoologia, 49, pp. 177-186; Fasola, M., Resource use of foraging herons in agricultural and nonagricultural habitats in Italy (1986) Colonial Waterbirds, 9, pp. 139-148; Fasola, M., Alien, R., Conservation of heronrysites in North Italian agricultural landscapes (1992) Biological Conservation, 62, pp. 219-228; Fasola, M., Ghidini, M., Use of feeding habitat by breeding Night Heron and Little Egret (1983) Avocetta, 7, pp. 29-36; Hafner, H., Dugan, P.J., Boy, V., Use of artificial and natural wetlands as feeding sites by Little Egrets (Egretta garzetta L.) in the Camargue Southern France (1986) Colonial Waterbirds, 9, pp. 149-154; Hafner, H., Fasola, M., The relationship between feeding habitat and colonially nesting Ardeidae (1992) Managing Mediterranean Wetlands and Their Birds, pp. 194-201. , (C.

In total, 267 regurgitations from little egrets, 247 from night herons and 19 from squacco herons (only in 1995) were collected and analyzed. Each prey item was identified to the lowest possible taxon. The dry mass of each prey taxon was also estimated from oven-dried prey specimens collected in the field. At least 58 different prey taxa were identified among 5,108 items found in little egret regurgitations, at least 45 taxa among 2,373 items regurgitated by night herons and 12 taxa among 277 items from squacco herons regurgitations. Differences were detected between the three ardeid species in the proportion of each prey category. Little egret nestlings were mainly fed fish (39.6\% by number) and insects (32.0\%), but amphibians and fish were the most important groups by biomass (44.9\% and 32.9\% respectively). The proportions of prey categories varied significantly between years ({\textdiv}212 = 922.91, p < 0.001). The night heron nestlings were mainly fed insects and the crustacean Triops cancriformis, although the dry mass of the latter contributed little to the consumed biomass (4.0\% compared to the 37.9\% of insects). Small mammals and reptiles were included in the diet of the young night herons, while the fish they ate were much bigger than those consumed by little egret nestlings. The proportions of the night herons{\textquoteright} main prey categories varied significantly between years ({\textdiv} 224 = 598.67, p < 0.001). Squacco heron chicks were fed mainly insects (50.9\%) and amphibians (31.8\%), the latter being more important by biomass (73.6\%). In a cluster analysis, diet of young little egrets and night herons showed greater similarity from 1988 to 1990 than between 1994 and 1995, suggesting temporal changes in prey use. Study years tended to group separately for each species, but those of the little egret were more scattered in the cluster than the night heron{\textquoteright}s, thus reflecting greater prey use variability. The diet of the squacco heron was similar to that of the little egret when prey type frequencies were considered, but closer to the night heron{\textquoteright}s by dry mass. The dry mass differed significantly between the species ({\textdiv}2 = 87.39, p < 0.001, Kruskal-Wallis test). This dietary segregation may be a mechanism that reduces competition among these ardeid species, especially when prey is limited.}, keywords = {Ardeidae, Axios, diet, Little Egret, Night heron, Squacco heron}, author = {Kazantzidis, S. and Goutner, V.} } @article {7555, title = {Abundance and habitat use by herons (Ardeidae) in the Axios Delta, northern Greece}, journal = {Journal of Biological ResearchJournal of Biological Research}, volume = {10}, year = {2008}, pages = {129-138}, keywords = {kape aves}, author = {Kazantzidis, S. and Goutner, V.} } @article {7557, title = {Comparative nest site selection and breeding success in 2 sympatric ardeids, Black-crowned Night-Heron (Nycticorax nycticorax) and Little Egret (Egretta garzetta) in the Axios Delta, Macedonia, Greece}, journal = {Colonial WaterbirdsColonial Waterbirds}, volume = {20}, number = {3}, year = {1997}, note = {TY - JOURCited By (since 1996): 11Export Date: 7 September 2006Source: ScopusReferences: Allieri, R., Gariboldi, A., Fasola, M., Breeding habitat requirements of herons in the Central Po Valley (1988) Naturalista Sicil.

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.
