How long does it take for sparrow eggs to hatch?

Ever wondered how long does it take for sparrow eggs to hatch? Some people might think that all bird eggs hatch at the same time, but that’s not the case. The length of time it takes for a sparrow egg to hatch can depend on many factors, including the temperature of the incubator and the age of the parent birds.

In general, it takes about two weeks for a sparrow egg to hatch. However, if the eggs are incubated at a lower temperature, it can take up to three weeks for them to hatch. Also, if the parents are older, they may not be able to incubate the eggs as long, which can also shorten the hatching time.

In this article, we’ll look closely at what goes into sparrow eggs hatching and when birders can expect them to start hatching.


The Gestation Period for Sparrows

In order to understand how long does it take for sparrow eggs to hatch, we need to understand the gestation period. Sparrows often lay eggs in the summer when they are nesting. However, they’re also seen laying eggs in the early spring also. Sparrows lay from around 3 to 7 eggs, although the most typical number is 4 to 5. Young house sparrows stay in the nests for 15 days after hatching everywhere for 10 to 14 days.

It’s worth noting that in higher latitudes, where average temperatures are often colder, eggs might take up to 14 days to hatch. Because these species use the nest almost all year, sparrows can utilize it for resting all day and nesting at night in the fall and winter.

You can find the nest in any accessible location near a human settlement. It includes buildings, trees, and birdhouses. This bird’s ability to reproduce is due to its adaptability and the number of broods it can raise. But, what’s the structure of a sparrow’s nest? 

The nest is circular and is 8 to 10 inches in diameter. On the outside, the nests are generally formed of gritty material. Straw, twigs, paper, leaves, and other natural materials are commonly employed. In addition, feathers or fine grasses are frequently used to coat the inside.

How long does it take for sparrow eggs to hatch?

On average, 12 to 13 days are necessary for egg incubation. However, the period can vary in the case of different sparrows. Let’s find out the hatching and other related information for chipping sparrows.

Chipping sparrows build nests 3-10 feet off the ground. The female sparrows will develop and organize the nest during the nesting phase. Then, males will try to encircle the female and protect the nest. The finished nest will be 2.2″ deep and 4.5″ broad, with the female laying 2-7 eggs. The eggs are 0.6-0.8″ in length and 0.4-0.6″ in breadth.

This bird species’ nesting season lasts 10 to 12 days. However, the incubation period will require around 10 to 15 additional days. Light blue or pale white eggs and brown spots are typical for the eggs of chipping sparrows.

If the weather condition isn’t suitable, female birds might take additional time to lay eggs and start the incubation period. Next, we’ll learn how and when the young sparrows leave their nest.

How many Eggs do Sparrows lay?

Before answering that, note that there are different types of sparrows. In addition, not all sparrows will lay the same amount of eggs. For example, a house sparrow usually lays around 4 to 5 eggs. On the other hand, a chestnut sparrow will only limit the number from 3 to 4. Also, a Eurasian tree sparrow will lay around six eggs.

The average clutch size of a female house sparrow is five eggs. However, investigations on nesting house sparrows have discovered that clutch sizes can range from one to eight eggs.

The eggs are speckled with brown and range in color from white to dull brown. The female incubates the eggs for the most part. But, the male may raise his egg sitting close to 50% of the time near the end of incubation.The incubation period for House Sparrows is approximately 12 days. However, you can expect the young birds to leave the nest after more than two weeks. Both sexes feed the young sparrows. After flying the coop, the male continues to provide the fledglings, while the female starts the next brood.

These eggs are usually small, at around 0.5 to 0.7 inches. However, the color can vary from white, green, and brown. Note that the white eggs might have brown spots at times. Now, let’s talk about the eggs of song sparrows. The song sparrow eggs are usually brown. However, the width is around 0.7 inches, along with a length of 0.9 inches.

Overall, the chestnut sparrow eggs are spherical and might have white or green spots and general brown color. There’s another type of sparrow, which is the black-chinned sparrow. These sparrows have a bluish color with green spots around the egg. The width of the eggs is 0.6 inches, and the length is around 0.4 inches only. The clutch will be about two to five eggs and the incubation period is roughly 13 days.

When do Sparrows leave the nest?

The young sparrows are completely naked and have glowing pink skin as they emerge from their eggs. Unfortunately, most newborn chicks are helpless and clumsy. The young sparrows can’t open their eyes for the first few days.

When these chicks are at least a week old or a bit more, they can regulate their body temperature independently for the first time. Both parents are equally responsible for rearing and feeding their young sparrows. Before the young sparrows are prepared to leave their nests, they fledge for about 17 to 18 days.

When they first arrive in the nesting, the chicks are fed mostly invertebrate larvae and caterpillars. Afterward, nestlings eat insects like butterflies, fleas, wasps, and locusts. When insects are scarce, they feed on vegetables and fruit seeds in the winter. But when it gets older, the sparrow eats many more seeds, grains, and veggies.

How Long Do Sparrows Live?

On average, a house sparrow’s lifespan is 2 to 5 years in the wild. However, some individual birds might also live for more than 6 years. According to experts, the oldest recorded age for a house sparrow is about 15 and 3 months. Now, let’s compare this with the life expectancy of another type of sparrow, called the tree sparrow.

The maximum lifespan of a tree sparrow is around 7 to 8 years only in the wild. However, in captivity, this bird species might live for 10 to 12 years or even more.

How many times a year do sparrows lay eggs?

House sparrows usually lay eggs 2 to 5 times a year. Therefore, most of the sparrows will lay eggs from April to August. However, laying eggs isn’t uncommon from the early spring to summer. Also, chipping sparrows are seen to lay eggs in the winter. So, we can say that a sparrow will lay eggs three times a year on average. However, weather conditions, mating compliance, and other factors can affect the frequency.

Note that sparrows will lay the most eggs during the spring and summer. It’s because the weather conditions are pretty suitable at that time. Also, mating is more accessible as the females and males work together during the summer.It’s fascinating that male sparrows are protective of females. While a female builds the nest, the male will protect his mating partner. In this way, their nesting becomes successful.

Overall, if conditions are viable, sparrows can lay or hatch eggs multiple times a year. Of course, different sparrows have different egg-laying frequencies. But, most of the species lay eggs at least three times a year.

Do Sparrows Migrate?

Every year, around October and November, house sparrows start migrating to other regions. The primary reason behind this is the cold weather that arrives during winter. Also, the food availability decreases as the leaves of trees fall off and insects become scarce.

So, these birds fly to warmer regions where they can find enough food to survive the winter. In most cases, they don’t travel alone but in groups. Once they arrive at their destination, they form flocks with other sparrows and spend the winter together.

Meanwhile, tree sparrows don’t migrate but stay in their habitat all year. That’s because this bird can withstand harsh conditions and find enough food to survive even in winter.

Other sparrow species, such as the white-throated sparrow, engage in “partial migration.” It means that only some flock members migrate to other regions while the others stay back. The reason for partial migration is still unknown, but experts believe that it has something to do with the age and health of these birds.
