“…The feeding behavior and success of many ardeids is affected by the habitat or microhabitat type where the herons feed (Hafner et al 1986, Draulans and Hannon 1988, Maccarone and Brzorad 2002. This may be due to differences in habitat structure or prey availability (Richner 1986, Maccarone andParsons 1994).…”

To examine factors affecting feeding efficiency of grey herons (Ardea cinerea), the foraging behavior was studied at a reservoir in Asan city, Chungcheongnam-do, South Korea during the breeding seasons (from April to July) of 2006 and 2007. Four factors (age of foraging birds, time of day, breeding stage, and microhabitat type) were analyzed. Adults were more efficient foragers than recently fledged juveniles, and they had a higher success rate than juveniles. About half of the adults caught large prey, whereas most juveniles caught only small prey. Adult grey herons had different feeding efficiency according to the breeding stage. Pecking and capture rates were high during the late period (fledging stage), and biomass intake rates were high during the early (incubating stage) and late periods. However, time of day had no significant effect on foraging activity of adult grey herons. Feeding activities of adult grey herons also showed significant variation among microhabitat types. Pecking and capture rates were higher in the submerged plants area, but capture success rate and biomass intake rate were not different according to microhabitat type.

“…According to optimal foraging theory, foragers search for prey that will provide the highest energetic benefit (Stephens and Krebs, 1986). However, individuals differ in their behavioural choices, especially juvenile birds with a lack of relevant experience and abilities and are usually less effective in finding food due to selection of less favourable areas, times for feeding and making mistakes (Draulans and Hannon, 1988;Voisin, 1991;Watson and Hatch, 1999;Kushlan and Hancock, 2005;Skórka et al, 2016). However, since many studies compare foraging success of different age classes at the same time (e.g.…”

The components of foraging behaviour and success of adult and juvenile Grey Heron Ardea cinerea were studied at the Dobczyce Reservoir (southern Poland) in July and September 2015. Juvenile and adult birds moved at similar rates during both months. Fish capture attempt rate was significantly higher for juvenile birds than for adults in July but not in September. Capture rate and foraging success probability (number of captures over all attempts) was significantly lower in juveniles in July but not in September. The foraging success probability of juveniles increased from July to September. Adult and juvenile birds caught mostly small fish, with no differences in size. However, handling time in juvenile birds was much longer than in adults in July but not in September, after controlling for differences in prey size. Thus, juvenile Grey Heron increased their efficiency of catching fish from July to September by reducing the number of mistakes, probably as a result of experience.
