• The house sparrow has the AMY2A gene, which helps it better break down starch. This gene allows it to break long starch molecules into shorter ones.

The house sparrow’s diet consists of seeds, grains, small insects, and food waste; during summer, the species more frequently catches insects for its young. The house sparrow gathers food on the ground, on trees, and near buildings, employing an active hunting strategy to search for and obtain sustenance. Its food includes cereal seeds, insects, crumbs, berries, plants, grain, an insect, and a seed. The daily food requirement ranges from 6 grams to 12 grams, and the species preys upon beetles, flies, true bugs, butterflies, bedbugs, grasshoppers, dragonflies, mayflies, and net-winged insects. Cats and civets prey on house sparrows.
