Foraging guilds of aquatic birds on productive boreal lakes: environmental relations and concordanced species composition for four of five guilds (Diving Carnivores excepted). Randomization tests also showed that patterns of species composition among lakes were similar between foraging guilds for eight out of 10 pairwise comparisons (both exceptions involved Surface-foraging Carnivores). Because o

Water bird guilds and their feeding connections in the Bodrogzug, Hungaryalcon (.), red-footed falcon (.), and corncrake (.). Compared to the total bird fauna of the investigated area, the highest ratio of aquatic bird species was present in the oxbow areas covered with aquatic vegetation. Considering the role of aquatic birds in material and energy cycles, three main sp

Effects of small-bodied fish on invertebrate prey and foraging patterns of waterbirds in Aspen Parkl biomass increased, but teal foraging effort did not return to pre-treatment levels. Amphipods and chironomids increased following fish addition, possibly due to indirect positive effects of fish. Red-necked grebes did not exhibit any changes in foraging effort as a result of the fish addition or th

ZEST

A comparison of three methods to investigate the diet of breeding double-crested cormorants (,) in te and stomach analysis. The non-lethal method of regurgitate collection and analysis appears most practical in assessing cormorant diet in this system. In combination with information on avian foraging ecology and prey populations, these data may be used to investigate the relationships among cormor
