Sparrows are cavity nesters, which means they prefer to build their nests in enclosed spaces. They can be found nesting on ledges of houses and buildings, in pipes, under awnings and roofs, and in other similar places.

Sparrow nests are round or dome-like in shape and typically measure 8 to 12 inches across. Nests not built inside an enclosure or cavity tend to be roofed and have a side entrance.

The interior part of the nest is generally constructed from coarse materials, while the exterior is made from finer materials.

Interestingly, built-in nest cavities, nesting boxes, and other enclosures do not usually have any roofing but only a cup. It allows the parents to keep an eye on their young while still being able to access the nest.

Additionally, house sparrows build adjacent nests sharing common walls. It helps to keep the communal nesting place clean and organized.

Lastly, the size of the communal nesting place is variable as different groups of house sparrows will choose different spots depending on availability.

Sparrow eggs are typically a light brown but can be greenish or bluish-white. They are marked with gray to brown dots and spots, which form a wreath around the wider side of the egg. The markings are more pronounced on some eggs than others.

Interestingly, the female sparrow begins to lay eggs as soon as the nest is finished. In addition, they will start laying eggs eight days after the chicks leave. The clutch size averages five eggs but can range from 1 to 8.

After the female sparrow lays her last egg, she will incubate the eggs. The entire process takes around 11 days, and during this time, the mother will take turns incubating the eggs with her partner. It ensures that at least one parent is always watching over the nest.

Sparrow eggs are laid in clutches of 3-12 eggs. The incubation period, or the time it takes for the eggs to hatch, ranges from 11-14 days. And since temperatures are usually colder in higher latitudes, it takes longer for the eggs to hatch up there.

Facts about House Sparrows Bird Species

In addition to the facts above, house sparrow eggs vary in color, shape, and size. Sparrow nests are typically dome-shaped and are constructed outside of natural cavities. They have an approximate diameter of 8 to 12 inches.

Male House Sparrows perform a courtship ritual to win the affection of a female. It may involve following her around or singing and displaying feathers.

Interestingly, male House Sparrows will mate with different females during the breeding season. It is since they only have a short time to reproduce.

Another interesting behavior during the mating season is dust bathing. It’s believed that this is how the sparrows spread their scent around and let other potential mates know that they are ready to mate.

In spring, they will move northward into more temperate areas. And, in the fall, they will head back south again.

Sparrows typically leave the nest around two weeks after hatching. Adults also form flocks that center around sources of food, roosting, and nesting sites.

Older males are at the highest ranking in these flocks, and they get first access to food and mates. Females have prime access to food, females, and nesting places.

Interestingly, sparrow nests and eggs have a specific appearance. For example, male sparrows with little to no black on their bibs rank below females in the social hierarchy. Additionally, old or younger males occupy a lower ranking than female sparrows.

Conclusion

Sparrows have been able to thrive and become one of the most common birds by associating closely with humans. It allows them to take advantage of human-made structures for nesting and access food sources. Sparrows can be pesky birds. They are aggressive and tough, so they often drive away other, more timid birds.
