How many years can the Eurasian Tree Sparrow live? A detailed look at the lifespan of this little bird

The Eurasian Tree Sparrow generally can live 7-8 years. The Eurasian Tree Sparrow has a fairly varied diet, feeding mainly on plant-based foods such as grain kernels, grass seeds, seeds and fruits, and during the breeding season it also eats large numbers of insects; especially the nestlings, which feed almost entirely on insects and insect larvae. They are generally local resident birds, breeding locally.

I. The Eurasian Tree Sparrow's habitat

The Eurasian Tree Sparrow is one of the most widely distributed, numerous and most common small birds in the world, living mainly in human residential environments; whether in mountains, plains, hills, grasslands, marshes and farmland, or in towns and villages, it is found in most places where humans gather. Its habitat ranges from 300-2500 m in altitude, and in China's Tibet region it can even reach 4500 m. The sparrow's habitat is very varied, but it generally tends to live in residential areas or the fields nearby. It mostly feeds in fixed places and rests in fixed places; by day it mostly moves within a range of 2-3 km, and at night it hides in caves under the eaves or in nearby earthen holes, rock crevices, and the woods beside the village.

II. What food does the Eurasian Tree Sparrow eat?

Its diet is fairly varied, feeding mainly on plant-based foods such as grain kernels, grass seeds, seeds and fruits, and during the breeding season it also eats large numbers of insects; especially the nestlings, which feed almost entirely on insects and insect larvae. According to extensive research by scholars across the country from the late 1950s to the early 1960s on the sparrow's diet, the Eurasian Tree Sparrow feeds mainly on the seeds of various crops. For example, in more than 800 bird stomachs examined throughout the year in the Hebei region, various crops accounted for 52.22% of the annual diet, with the rest entirely crop and wild plant seeds, among which the crop seeds were mainly grain kernels, wheat grains, rice grains, broomcorn millet, etc.; the nestlings, however, feed almost entirely on insects, especially beetles and other Coleoptera insects, followed by Lepidoptera and Homoptera insects.
