Bird food can vary depending upon dietary habits and beak shapes. Dietary habits refer to whether birds are naturally omnivores, carnivores, herbivores, insectivores or nectarivores. The shape of the beak, which correlates with dietary habits, is important in determining how a bird can crack the seed coat and obtain the meat of the seed. [2]
The many sparrows feed chiefly on weed seeds, but more acceptable plants from the gardener's point of view can be offered to them: so-called millets (Panicum, Setaria, Eleusine) princes' feather (Amaranthus, Polygonum) chamomiles, white and yellow ; California poppy (Eschscholzia californica) tarweed ; bachelor's buttons
Hummingbirds, sunbirds and other nectivorous birds seek nectar. Mixed seed and black-oil sunflower seed is favoured by many seed-eating species due to its high fat content and thin casing. In Australia, meat, especially raw beef mince (or ground beef), is commonly fed to wild carnivorous birds such as Australian magpies and kookaburras.

Frugivore seed dispersal is a common phenomenon in many ecosystems. However, it is not a highly specific type of plant–animal interaction. For example, a single species of frugivorous bird may disperse fruits from several species of plants, or a few species of bird may disperse seeds of one plant species. [3]
An edible seed [n 1] is a seed that is suitable for human or animal consumption. Of the six major plant parts, [ n 2 ] seeds are the dominant source of human calories and protein . [ 1 ] A wide variety of plant species provide edible seeds; most are angiosperms , while a few are gymnosperms .
