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.
folivores: birds that forage for and eat leaves, such as hoatzin and mousebirds. [141] [146] frugivores: birds that forage for and eat fruit, such as turacos, tanagers and birds-of-paradise. [146] granivores: (sometimes called seed-eating): birds that forage for seeds and grains, [149] such as geese, grouse and estrildid finches. [141] [146]
Browsing is a type of herbivory in which a herbivore (or, more narrowly defined, a folivore) feeds on leaves, soft shoots, or fruits of high-growing, generally woody plants such as shrubs. [1] This is contrasted with grazing , usually associated with animals feeding on grass or other lower vegetations.
The yellow-tailed black cockatoo's diet primarily includes seeds of native and introduced plants while also feeding on wood-boring grubs. They nest in large hollows high in old growth native trees (~ greater than 200 years old), generally Eucalyptus regnans .
Birds of the crow family, Corvidae, are the primary distributor of the conifer seeds. These birds are known to cache 32,000 pine seeds and transport the seeds as far as 12–22 km (7.5–13.7 mi) from the source. The birds store the seeds in the soil at depths of 2–3 cm (3 ⁄ 4 – 1 + 1 ⁄ 4 in) under conditions which favor germination. [27]

Plant foods include leaves, grass, berries and seeds. Weka are important in the bush as seed dispersers, distributing seeds too large for smaller berry-eating birds. [20] Where the weka is relatively common, their furtive curiosity leads them to search around houses and camps for food scraps, or anything unfamiliar and transportable. [6]
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 ...
