Eurasian tree sparrow
The Eurasian tree sparrow is a predominantly seed and grain eating bird which feeds on the ground in flocks, often with house sparrows, finches, or buntings. It eats weed seeds, such as chickweeds and goosefoot, spilled grain, and it may also visit feeding stations, especially for peanuts. It will also feed on invertebrates, especially during the breeding season when the young are fed mainly on animal food; it takes insects, woodlice, millipedes, centipedes, spiders and harvestmen.
