abstract = {In an effort to assess the role of adaptive foraging
behaviour to the spatial and temporal heterogeneity as a
factor determining the success of the colony, we used
single-colony individual-based spatial models for a visual
foraging, the Great Blue Heron and a tactile foraging bird,
the Wood Stork. The model followed simultaneously daily
activities of individuals, their spatial movements, foraging
efficiency, bioenergetics and growth of the nestlings during
a nesting season. For each colony we used two scenarios; in
the first, that depicted a normal nesting season, the extent
and distribution of feeding sites led to successful
reproduction for both species. In the second, we simulated
increased precipitation regimes resulting in reversals in
water depth (i.e. increases in depth during the dry season
when water levels are normally falling). The results reveal
that Wood Storks were significantly more adversely affected
than Great Blue Herons by the prey dilution caused by the
reversals in water depth. In the latter scenario where
resources became scarce, resource predictability decreased.
The foraging birds that foraged in groups exhibited low
foraging success, resulting in poor reproductive
performance. This result was more pronounced in the case of
storks that foraged in groups than for herons foraging in
groups. Concluding, increased variance in precipitation
regimes is more likely to affect tactile rather than visual
foraging bird species. Further, in harsh climatic conditions
(increased precipitation and water level regimes) solitary
foraging was more beneficial for wading birds than group
foraging.},
