when do birds eyes open

This is the time of year when birds begin their reproductive cycle in the northern hemisphere. People find eggs, nests, and baby birds and try to help them. Generally, that is not a good idea. Only 10-20% of songbird eggs ever result in an adult bird. The eggs might be infertile, die during incubation due to genetic or environmental causes, or be eaten by predators. Weather might blow the nest out of the tree or the young might starve. When young birds leave the nest they cannot fly and are still dependent on their parents and the risk of death from predators and weather is amplified.

During the first five days after hatching, baby birds are blind, naked, helpless and cannot maintain a steady warm body temperature. During the next five days or so their eyes open, they develop thermoregulation, and grow some feathers. At about 10 days of age they leave the nest. They are now fledglings. Here’s something that most people don’t realize: the young jump from the nest, unable to fly, and for the next ten days or so are fed by their parents. Unfortunately this stage is when they are most likely to be seen and found by humans.

Humans, being the empathetic creatures they are, feel sorry for this poor bird that “fell from its nest” and try to “rescue” it. Don’t do it. The parents may not be seen but they are there, taking care of their offspring until the young can fly. If you take the bird away, you badly disturb the bird family and you are unlikely to take care of the bird as well as the parents can. And don’t try to return it to the nest. Leave it alone. Repeat: leave it alone.

Occasionally, a young helpless bird falls or is knocked from its nest or a tree trimmer trims the wrong branch and the whole nest comes down. It this case, the babies or eggs will not survive. So what do you do? Well, if you have a bird rehab center in your area, call them. They have the skills and dedication to take care of the birds. But don’t just pick up the bird or egg and take it to a vet or wildlife official or nearest biology department because it is unlikely that they will have the time or resources to devote to hatching an egg and/or raising a baby songbird.

You can try to raise the egg or young yourself, but there are three important caveats here:

Sure, it’s difficult to leave a baby bird alone when you see it on the ground. But this is how nature has operated for millions of years; human interference rarely helps. So leave the bird be unless you are absolutely certain the bird is abandoned and in trouble and you have a place to bring it for experienced care.

Of course, it’s hard to leave a baby bird on the ground unattended. However, for millions of years, nature has functioned in this way, and human intervention rarely helps. Thus, unless you are positive that the bird is lost and in danger and you have a location where it can receive professional care, leave it alone.

Occasionally, a tree trimmer will cut the wrong branch and the entire nest will collapse, or a young, defenseless bird will fall or be knocked from its nest. It this case, the babies or eggs will not survive. What should you do then? Well, give the bird rehabilitation center in your area a call. They are capable and committed to caring for the birds. It is unlikely that a veterinarian, wildlife official, or the closest biology department will have the time or resources to dedicate to hatching an egg and/or raising a baby songbird, so don’t just pick up the bird or egg and take it to them.

Since humans are compassionate beings, they attempt to “rescue” this unfortunate bird that “fell from its nest” out of sympathy. Don’t do it. Even though they cannot be seen, the parents are present and caring for their children until they are old enough to fly. Removing the bird will negatively impact the bird family, and you won’t be able to care for it as well as the parents can. And don’t try to return it to the nest. Leave it alone. Repeat: leave it alone.

Although you can attempt to raise the egg or young yourself, there are three crucial things to keep in mind:

The first five days following hatching are a time of blindness, nudity, helplessness, and inability to maintain a constant body temperature. For the next five days or so, their eyes open, they learn to regulate their body temperature, and they begin to grow feathers. At about 10 days of age they leave the nest. They are now fledglings. Most people are unaware of this, but the young leap from the nest, unable to fly, and are fed by their parents for the next ten or so days. Unfortunately, this is the stage at which humans are most likely to see and find them.

Most nest-dwelling birds hatch with their eyes closed. After hatching, they are largely immobile and depend on their mother for assistance with most activities, including feeding. They need a nest and the company of other chicks to stay warm because they are bare except for a thin layer of down. After hatching, precocial chicks usually open their eyes within a few hours. They are highly vulnerable to predation at this early stage of their lives because they are ground-dwellers.

The chick’s instincts will start to work once its eyes open. He’ll react to visual stimuli with flinching and cowering, and he’ll start experimenting with using his wings for balance when he walks around. After week two, when it has grown all of its feathers, the chick will use his beak to preen itself on instinct.

The rate at which young birds develop varies depending on the species and habitat of the bird. Precocial birds, like ducks and quail, for instance, have a high degree of independence from birth. They usually live on the ground and are not protected by a nest. These birds are born with open eyes and full vision. Alternative birds develop more slowly and are usually born in nests with their eyes closed.

A young bird’s eyes may open on days three or four of its life. Even though they hatched at the same time in the same nest, some chicks may take a little longer than others to open their eyes. The chick may be opening its eyes, but its visibility is still limited.

Usually, by the time the bird reaches day six of its life, its eyes will be completely open and developed. This is a significant turning point in a baby bird’s life since vision creates an entirely new universe of opportunities. Now that he has vision, he can investigate his surroundings and lay the groundwork for future growth.


How can you tell how old a baby bird is?

By observing the bird’s physical characteristics and behaviors, you may be able to estimate its age. For example, if the bird is covered in down feathers but doesn’t yet have many adult feathers, it is likely quite young. If the bird is starting to develop feathers on its wings, it may be a few weeks old.

What does a 3 day old bird look like?

Nestling (3-12 days old) A nestling will have open eyes and pin-like feathers sticking out over most of its body. A baby bird at this stage will have a small amount of head and neck control. If found on the ground, a nestling should be returned to the nest.

How long do baby birds stay with their mother?

After 2 or 3 weeks, most songbirds are usually ready to leave the nest. Other birds, such as raptors, may stay in the nest for as long as 8 to 10 weeks. In contrast, precocial birds spend hardly any time in the nest and are often seen wandering in search of food alongside their parents only hours after hatching.

When can baby birds fly?

Most baby birds stay in the nest for at least 10 days in the nest before flying off on their own. For birds like Baltimore orioles, bluebirds and rose-breasted grosbeaks, this happens typically between two and three weeks old. Some big birds, like owls, hawks and eagles, develop much more slowly.
