African penduline-tit (Anthoscopus caroli) hanging from the end of a branch and gleaning.. Gleaning is a feeding strategy by birds and bats in which they catch invertebrate prey, mainly arthropods, by plucking them from foliage or the ground, from crevices such as rock faces and under the eaves of houses, or even, as in the case of ticks and lice, from living animals.

Farmed birds that are fed with commercial bird food are typically given a pre-blended feed consisting largely of grain, protein, mineral, and vitamin supplements. Examples of commercial bird food for chickens include chick starter medicated crumbles, chick grower crumbles, egg layer mash, egg layer pellet, egg layer crumbles, egg producer pellets, and boiler maker med crumbles.

granivores: (sometimes called seed-eating): birds that forage for seeds and grains, [149] such as geese, grouse and estrildid finches. [ 141 ] [ 146 ] herbivore : birds that predominantly eat plant material, and mostly do not eat meat; especially of birds that are both granivorous and frugivorous or are grass eaters, such as whistling ducks ...
The feeding of wild birds has been shown to have possible negative as well as positive effects; while a study in Sheffield, England found that the abundance of garden birds increased with levels of bird feeding, multiple reports suggest that bird feeding may have various negative ecological effects and may be detrimental to the birds being fed ...
The breeding season usually coincides with a crop of seeds after the local rainy season and at this time the feeding flocks tend to break up into pairs. The nesting site is a slight depression in the ground, sometimes lined with a few pieces of dry foliage. Most typically, three cryptic eggs are laid, though occasionally there may be two or four.
Avian foraging refers to the range of activities and behaviours exhibited by birds in their quest for food. In addition to their unique body adaptations, birds have a range of described behaviours that differ from the foraging behaviours of other animal groups. According to the foraging habitat, birds may be grouped into foraging guilds ...
Herbivory is of extreme ecological importance and prevalence among insects.Perhaps one third (or 500,000) of all described species are herbivores. [4] Herbivorous insects are by far the most important animal pollinators, and constitute significant prey items for predatory animals, as well as acting as major parasites and predators of plants; parasitic species often induce the formation of galls.
