A Complete Guide on the Egg-Hatching Process in Birds

by M Asim

Birds are fascinating animals that are also very beautiful. The sight of birds in flight, with their exquisite wings and the freedom they symbolize, never ceases to astound people.

It also comes as no surprise that those who are passionate about birds are fascinated by anything related to the life cycle of birds. Birdwatchers are particularly interested in learning about the incubation and hatching phases of a baby bird’s life.

How long does it take for bird eggs to hatch? The type of bird determines the time window. While the mother keeps the eggs warm, the father searches for nourishment.

Bird Nesting Cycle: Birds nest, lay eggs, hatch

Breeding season brings forth the offspring of over 700 bird species in the nation. While bird nesting cycles may share many similarities, the length of time it takes for bird eggs to hatch differs depending on the kind of bird. Let’s review some information regarding the nesting bird cycle before delving into the different hatching time frames.

Nesting Spot: Every season, both migratory and non-migratory birds locate new nesting sites or use the same ones. Usually, the nesting site is close to a good food source and protected from predators.

Mating Process: During the mating season, male birds display their plumage and energy. The females use singing, beauty, and strength to select their partners. While some birds practice polygyny, others are devoted to their partners.

Constructing Nests: Avian species use a variety of locations to build their nests, including trees, the ground, burrows, garages, and chimneys. A variety of materials, including leaves, fur, thread, dirt, grass, plastic, paper, and more, are used to make the many types of nests.

When the moment comes for copulation, the female ovaries and male testes enlarge. The pigments appear soon after the eggshells begin to form in the first stage of embryonic development.

Laying Eggs: Depending on the kind of bird, the quantity, size, color, and texture of the eggs vary. There are other variables at work as well, including latitude, food, weather, the mother’s age, and the availability of calcium.

Incubation: Keeping the eggs at the proper temperature during this time is crucial. Many bird species have varied starting points for incubation. While some female birds start incubating after every egg is placed, others do so after every bird hatches.

Hatching: Each species of bird has a different hatching time. Eggs hatch in about 10 to 30 days on average. Due to the incubation process, they can hatch at different times or at the same time.

The male birds must bring food to the young birds at feeding time. Precocial birds leave their nests right away in search of food, although some birds remain in the nest. When the time comes for a bird to leave its nest, its young remain near its parent occupants until they are ready to go it alone.

How long do bird eggs take to hatch?

Usually, the incubation period of 10 to 30 days results in the hatching of the bird eggs. Larger birds require more days to hatch than smaller ones, and vice versa. The young birds go through a fledgling stage after they hatch. Additionally, during the incubation period, only one parent—typically the mother—remains with the eggs.

However, if you’re curious about how long does bird eggs take to hatch, let’s go find out.

Ruby-throated hummingbird 

Citrus orchards, scrublands, dry forests, and hedgerows are habitats for the Ruby-throated Hummingbird. During nesting season, the females build their nests on slender, descending tree branches. Usually located 10–40 feet above the ground, the 2” long and 1” deep nests can take up to 10 days to finish.

The clutch size of this bird species is one to three eggs, each of which is 0.3 inches wide and 0.5 to 0.6 inches long. The birds nest for 18–22 days, and it takes them 12–14 days to incubate their eggs. At 0.5g, the hatching white eggs are tiny and light.

Northern Cardinal

Usually found in densely forested areas, Northern cardinals lay their eggs and then eat insects. A few weeks before they build their nests, the male and female birds look for places to nest. They like short branches that are no more than 15 feet above the ground in dense vegetation.

Female northern cardinals usually lay two to five eggs, each measuring between 0.7 and 0.8 inches in width and 0.9 to 1.1 inches in length. The eggs hatch after 11–13 days of nesting, which lasts for 7–13 days. The eggs appear buffy, grayish, or greenish-white throughout incubation, with hints of light gray to brown.

Orioles from Baltimore

The Baltimore oriole prefers open areas over dense forests. The female must locate a slender top tree branch on which to construct their nest. With their woven, protruding bottom hanging nests, Baltimore orioles’ nests measure 3″–4″ deep, 3”–4” across, and 2”–3 wide.

This type of bird typically produces clutches of three to seven eggs, each measuring 0.8 to 1.0 inches in length and 0.6 to 0.7 inches in breadth. The 11–14 day period is the same for both nesting and incubation. The eggs are speckled with lavender, black, or brown and are either light gray or bluish-white.

American Goldfinch

Parks, suburbs, and residential areas with natural food supplies are common places to observe American goldfinch populations. The adult birds look for areas where they can see their nests from the ground, which are open nesting places. When completed, the nests measure 2-4.5″ in height and 3″ in diameter. They are compact.

Within a nest are two to seven eggs, measuring 0.6 to 0.7 inches in length and 0.5 inches in width. The eggs have little, pale brown dots on a bright blue-white background. The time it takes for a bird to nest is 11–17 days, and the eggs hatch in 12–14 days.

The American Robin

The American robin favors both wide-open areas and untamed environments. The female birds select the parallel, hidden tree branches as their nesting locations. The finished nest measures 6-8″ in diameter and 3-6″ in height.

The eggs laid by female American robins measure 0.8″ in width and 1.1–1.2″ in length. The females can deposit three to five eggs at a time. The eggs are fleck-free and either sky blue or blue-green. The incubation period for bird eggs is 12-14 days, while the nesting period is 13 days.

Carolina Wren

The Carolina wren can frequently be observed in forested regions, bushes in farmlands, and dilapidated buildings. They like to construct their nests between three and six feet above the ground, frequently in exposed tree cavities, as well as in abandoned boxes, flowerpots, and other discarded human debris. The nests of Carolina wrens, both male and female, can be 3 to 9 inches in length and 3 to 6 inches wide.

This type of bird typically lays three to seven pinkish-white or white-cream eggs with rusty-brown flecks. The Carolina wren has a 10–16 day nesting period and a 12–16 day incubation period.

Downy Woodpecker

The Downy Woodpecker’s natural habitat includes open forests, streams, groves, and suburbs. They like to construct their nests in dead trees, trees afflicted with fungi, or dead sections of living trees. A week or three is needed for the construction of the nest, which is then finished to measure 6–12″ deep and 1–1.5 broad.

The 18–21 nesting cycle produces 3–8 eggs, and it takes 12 days for the females to hatch the bird eggs. The eggs measure 0.8″ in length and 0.6″ in width. They are completely white.

Chickadee with a Black Cap

The Black-capped chickadee chooses to construct its nests in fresh or abandoned tree holes as well as specially designed nest boxes. Usually, there are one to thirteen white eggs with reddish-brown specks on them. The incubation period is 12–13 days, and the nesting period is 12–16 days. The eggs of the black-capped chickadee have dimensions of 0.6″ x 0.5″.

Eastern Bluebird

The nest boxes, artificial nesting places, and natural cavities are preferred by Eastern Bluebirds. While the females construct the nests, the males transport the materials for the nests. Two to seven pale blue eggs are produced throughout the 17–21 day nesting cycle. Incubation lasts 11–19 days on average, and the dimensions of the egg are 0.6–0.8 in width and 0.7–0.9 in length.

Chipping Sparrow 

Nests constructed by Chipping sparrows like Black Sparrow Frost range in height from 3 to 10 feet. While the males work to protect their nests, the females arrange them. When finished, the female builds a nest that is 2.2″ deep and 4.5″ wide, in which she lays two to seven eggs. The eggs are 0.6-0.8″ in length and 0.4-0.6″ in breadth.

This type of bird nests for nine to twelve days, followed by ten to fifteen days of incubation. Eggs are either pale white with black, brown, or purple flecks, or they are light blue in hue.
