Bluebird (blue corolla) with beautiful cobalt blue plumage and a distinctive crest – they are the most colorful of all corvids and one of the most recognizable birds in North America.
Like all corvids, blue jays are intelligent and resourceful, but what about little blue jays? Here’s a guide to everything you need to know about little blue jays!
What do juvenile blue jays look like?
Baby bluebirds are tiny when they hatch and are mainly gray with tinges of yellow and pink. They are blind with their eyes closed and may be covered in nude patches without feathers.
when hatching
Young bluebirds hatch mostly feathered, but may have bare, featherless patches. They are mainly gray with pink/yellow feathers underneath. For the first 4 to 5 days, their eyes are closed and will not open.
Although baby bluejays only wriggle on their first day, they can move around the nest by the second day. Newly hatched bluebird larvae are small, only about 50 mm long.

growth and development
Bluebirds grow rapidly during the first five days of life, and their plumage visibly darkens to an olive color. The blue feathers don’t start to grow until around day 14 and continue until around day 20, when the jays flake their feathers.
Development of the full blue plumage is not complete until another month or so after eclosion. However, juvenile bluebirds are relatively easy to identify by their blue-gray plumage and buff, fluffy plumage.

How big is the little blue bird?
Young bluebirds weigh about 5.5 grams when hatched and are only 51 millimeters long. By the fifth day, bluebirds had weighed about 20 to 28 grams and were about 76 mm long.
Why have you never seen the little blue bird?
Young bluebirds do not leave the nest for 17 to 22 days, but are flightless for a week or so after eclosion.
Once fully fledged, chicks remain close to their parents. Parents often move away from the nest while staying within the foliage range deep in the treetops.
Blue jay juveniles are vulnerable and easy to spot if they are wandering around on the ground. However, if you spot one, its parents are probably watching it (and you!) from their treetop perch, so think twice before touching or moving it.

What is the name of the little blue bird?
Baby bluebirds don’t have specific names. After hatching, young bluebirds are called fledglings. Then, when they spend all their time in the nest, they develop into fledglings. Eventually, baby bluejays become fledglings, juveniles, and adults.
What do little bluebirds eat?
Young bluebirds eat anything their parents bring to them, including insects, berries, seeds, and grains. While bluejays also eat the meat of small animals and other birds, young birds are less likely to digest this meat. Soft food is preferred.
In the first few days after hatching, the male provides the vast majority of food, but if food is scarce, the female will join in. Then, after a few days, the female usually joins the male in foraging for more feed for the hungry chicks.
After that, the males usually feed the chicks as well, but the females have been observed reaching into the chicks’ beaks and redistributing the food.

Do both parents feed baby bluebirds?
During the first few days after hatching, the male is responsible for most of the foraging and feeding of the chicks. However, females will often forcibly redistribute food by reaching into the chicks’ beaks.
The females usually join the males after about 4 to 5 days. Both birds feed the chicks as the birds approach the wing. Parental feeding continues for one to two weeks after the bluebird chicks have fledged.
What do blue jay eggs look like?
Blue Jay eggs typically measure 28mm x 20mm and are predominantly ovoid. Colors range from shades of blue to green, olive, and light brown.
They have brown spots or spots, mainly towards the larger end. So while blue jay eggs look similar to those of most corvids, they vary widely, especially in color and shape.

How long does it take blue jay eggs to hatch?
Blue jay eggs are about 17 to 18 days before they hatch.
How many children does a blue jay have?
Female bluebirds usually lay 2 to 7 eggs, but 4 to 5 are more common. Very few chicks survive to adulthood.
When Do Bluebirds Lay Eggs?
Bluebirds lay eggs almost exclusively in March, April and May.
Spawning in May usually only occurs in the north, or when it is particularly cold. In the South, spawning may begin as early as early March, but rarely earlier.
- Michigan: Early May
- Minnesota: End of April
- Kentucky and Kansas: mid-April
- Arkansas: End of March
- Florida: Early March

How do bluebirds feed their chicks?
Presumably, blue jay parents regurgitate some of the harder food into the chicks’ beaks, but may feed most of the food entirely to the chicks. Larger pieces of food will shred before feeding.
Young bluebirds feed on berries, insects and seeds. Insects are ideal because they are soft and rich in protein and fat.
How long do baby bluebirds stay with their parents?
In most cases, bluebirds fled after only 17 to 21 days after hatching, but they stay very close to the nest (usually around 25 meters) for another 2 to 3 weeks.
After that, young bluebirds typically remain within the family unit for another 2 to 3 months, at which point they have grown most of their adult feathers and fly off to establish independent territories. Young bluebirds often harass their parents for food well into the summer.

Does Bluebird have a helper?
Helpers are unpaired birds that help a pair with everything from nest building and hatching to brooding and feeding.
Bluebirds sometimes have nesting helpers, although this is much rarer than in other corvids such as crows.
Bluebird helpers have been observed helping with nest building and feeding young. It’s unclear if they’re related to the pair (like last year’s Young), or if they’re not.
Expert Q&A
question
When Are Baby Bluebirds Most Vulnerable To Cats?
The BirdFact team
In general, baby bluebirds are most likely to be predated by cats while they are in the nest – especially around the edges of the nest, and in the first few days after they leave the nest.
Bluebirds are very aggressive when defending their nests, which often scares off predators. With cats, similar to other predators, parents will usually mob the cat to try to scare it away and protect their young.

I am broadly interested in how human activities influence the ability of wildlife to persist in the modified environments that we create.
Specifically, my research investigates how the configuration and composition of landscapes influence the movement and population dynamics of forest birds. Both natural and human-derived fragmenting of habitat can influence where birds settle, how they access the resources they need to survive and reproduce, and these factors in turn affect population demographics. Most recently, I have been studying the ability of individuals to move through and utilize forested areas which have been modified through timber harvest as they seek out resources for the breeding and postfledging phases. As well I am working in collaboration with Parks Canada scientists to examine in the influence of high density moose populations on forest bird communities in Gros Morne National Park. Many of my projects are conducted in collaboration or consultation with representatives of industry and government agencies, seeking to improve the management and sustainability of natural resource extraction.
