In most urban and suburban areas it’s INCREDIBLY COMMON to see House Sparrows. They owe their success to their ability to adapt and live near humans. Unlike most other birds, they love grains and are commonly seen eating bread and popcorn at amusement parks, sporting events, etc. At your bird feeders, they especially love eating cracked corn, millet, and milo. The widely reported global insect decline may also be a significant factor. Many think of house sparrows as vegetarians, gobbling bird seed and grains.
Song sparrows are common in California, especially in wet, shrubby, and open areas.
They like being on the ground for shade and protection from predators. They are rarely seen, but you may sneak a peek as a male sings from a shrub or low tree. Only the males sing songs that are a few seconds long, with a mix of jumbled whistles and trill notes. Green-tailed Towhees prefer to live in shrubbery forests, giving them the best place to forage on the ground and be protected. They are hard to see in the dense foliage, but males can be found singing from the tops of shrubs.

Look for them spending much of their day foraging in thick weedy fields or pastures foraging for food. That’s where they hop forward and quickly hop backward again, overturning the fallen leaves to peck any seeds or small insects. In fact, they have to take in 30% of their body weight in food and water each day. Unfortunately, that means going a day without eating is usually a death sentence for them. The coloration of this sparrow varies depending on its location.

They use the double scratch technique to find seeds and insects in the soil. Males sing a song starting will a buzz, followed by a few clear notes, and ending with a trill note. Their song is very different from other sparrows in California. Green-tailed Towhees work hard to build their nest, but sometimes they use porcupine hairs inside the nests for added support, which is surprising and seems dangerous for the babies.
Male and female House Sparrows look similar, but males are slightly darker in color, and have a black patch on their throat. The top half of this bird’s body is dark brown with black mottling, and its underside is lighter tan. Populations from their northern limits in Canada may retreat south for the winter, but these birds are seen all year round in North America and the United Kingdom. There are some migratory populations in Central Asia, however. House Sparrow nests are made of coarse dried vegetation, often stuffed into the hole until it’s nearly filled. The birds then use finer material, including feathers, string, and paper, for the lining.

It’s still abundant in many places – including my neighborhood, where a mix of native vegetation, bird feeders and backyard chicken coops provide the diversity of habitat and food sources that enables these birds to thrive. Epigenetic variation, namely DNA methylation, has also begun to be investigated in house sparrows (Kilvitis et al., 2018; Kilvitis et al., 2019; Riyahi et al., 2017). It has been hypothesized that DNA methylation or other molecular epigenetic mechanisms may have affected the ability of populations to colonize new areas (Box 1). In Australian house sparrows, a similar pattern was found as well as an epigenetic signature mirroring that of genetic population clustering arising from the original source population (Sheldon et al., 2018).
They are frequent visitors to backyard feeders, where they eat most kinds of birdseed, especially millet, corn, and sunflower seed. Find out more about what this bird likes to eat and what feeder is best by using the Project FeederWatch Common Feeder Birds bird list. Also known as cinnamon or cinnamon tree sparrows, these small seed-eating birds are found in parts of eastern Asia and the Himalayas. These sparrows don’t put up with birds coming into their territory during the breeding season.
What do baby house sparrows eat?
Thankfully, if you’d like to hear their song, they’re relatively easy to attract to feeders and gardens. These birds like to visit backyards that provide them with food and a place to hide like a brush pile. They’ll eat small seeds on the ground, like sunflower and millet, that have spilled out from your feeders. But you may spot one in your yard looking for cover in winter, especially if you live by a field or have a brush pile for them to hide inside. If you want to attract these sparrows to your backyard, use sunflower seeds. Just make sure the food is placed on the ground, as they won’t fly up to feeders.
Incubation of the eggs
This jumble of definitions has led some to claim that 'model' is one of the most under-powered concepts in biology (Katz, 2016). These challenges motivated us to think hard about how house sparrows could serve as models (Bolker, 2009). Houses, barns, buildings, and utility structures provide plenty of nesting places to house sparrows.
One form of epigenetic potential is the number of CpG sites (sequences in the genome where DNA methylation can occur) in gene promoters. For a time, some sources refer to a “sparrow fad,” with private individuals breeding birds, and others catching them and releasing them into new areas. Nest boxes were installed in cities to increase sparrow populations. Ornithologists and others raised concerns over the merits of house sparrows, but their arguments proved futile against sparrow enthusiasts releasing cages full of birds. Outside of urban areas, house sparrows feed largely on animal feeds composed of grains like sorghum, cracked corn, wheat, and oats.
Originally from Europe, Asia, and North Africa, house sparrows can now be seen almost everywhere people live and work. Recently, an annotated genome became available for house sparrows (Elgvin et al., 2017). The genome belongs to a female house sparrow from a pedigreed, inbred population from the island of Aldra in Norway, and was studied to better understand speciation in the Italian sparrow (P. italiae; Elgvin et al., 2017).

Their most prominent markings are a small pale wing bar and a pale stripe from the eye to the nape. Male and female House Sparrows have very different colors and markings, which makes identifying them easy to distinguish. Adult males have a black mask, throat, and bib, and whitish cheeks. The crown of the head is gray, and the back of the head is rufous brown. Their underparts are grayish, and their wings and backs have rich, warm brown and black markings. Nests in tree cavities and birdhouses, including Purple Martin houses.
