Abstract Herons are, fundamentally, birds that wade in the water to capture aquatic prey with their bills. Many of the biological characteristics, described in Chapter 1, influence and reflect the way they feed. Specifically, the archetypical heron is a medium-sized bird, relative to the range of all birds, with long legs, long neck, and

When not tied to breeding colonies, seabirds can range over vast areas of sea in search of food, and, if necessary, migrate to avoid a hostile winter environment. As the onset of breeding approaches however, they must obtain enough food to undertake the journey to their breeding colonies.

(Uploaded by Plazi for the Bat Literature Project) This chapter discusses roosting and its importance in foraging for bats. It describes roosting ecology or the significance of finding the right roost, and enumerates some of the potential benefits of choosing a suitable roost such as: protection from the weather and predators, reduced thermoregulation ...

Abstract Grebes obtain most of their food by diving. Since their feeding is usually hidden to our eyes, finding out how they feed and what they eat presents a problem. Pertinent questions relate to hunting methods, depths, where they find their food, etc.

Abstract All the Australian estrildines feed on the seeds of grasses, but no species concentrates on them to the same extent as Zebra Finches. Six quantitative studies of diet have been published since Immelmann’s (1962a, 1965a) original observations, and despite differences in habitat and climate among the studies, they agree on two ...

Ecological Physiology: Feeding
1987Phagocytosis is an essential feature of protozoan feeding and it is the subject of both this and the following section. Some protozoa acquire additional energy and materials for growth by other mechanisms, such as the uptake of dissolved materials, which will be discussed at the end of this section, while symbiotic relations with photosynthetic ...

Feeding: An Ecological Approach
1979Publisher Summary Physiological and ecological approaches to comparative studies of feeding behavior have a common basis in energy regulation. This chapter describes energetic determinants of general costs and benefits functions, provides evidence for food choice, meal patterns, and resource exploitation as determined by the economics of energetic ...

Feeding rate as valuable information in primate feeding ecology
Primates, 2009In this review I outline studies on wild non-human primates using information on feeding rate, which is defined as the food intake per minute on a dry-weight basis; further, I summarize the significance of feeding rate in primate feeding ecology. The optimal foraging theory has addressed three aspects of animal feeding: (1) optimal food patch choice ...
