You must have come across a female bird looking after its brood in a nest at some point.Did that ever make you wonder why parent birds did so and how long it took baby birds to fledge? Well, while some birds hardly take a few days, some other species can take three weeks to fledge!Birds are rather fascinating creatures and their beauty and grace are second to none. In fact, studies and observations have also shown that their ways around the world are just as interesting as their feather patterns. Baby birds, after they are born, are taken care of by their parents in a rather adorable fashion and we have some fledging facts for you ahead. Make sure to keep reading!If you enjoyed this article, why not also check out how long do birds live and are birds cold-blooded.Do baby birds leave the nest at night?Baby birds, also known as nestlings or fledglings, rarely leave their nests at night. This is because young birds do not have the flight feathers that would allow them to fly out of a sticky situation. The nighttime also brings some predators along with it in the form of owls and other predatory animals. Hence, these helpless babies would end up in more of a vulnerable situation if they were to leave the nest before their bodies had developed.Chicks have a lower chance of survival if they choose to leave the nest early, and hence, they choose to stay in their parents’ territory and feed through them. This protects them from some danger, and also opens them to a different array of dangers at the same time. Predators of the night, however, are more dangerous for fledglings since most baby birds do not have the eyes that would enable night vision. Therefore, nightly adventures are hardly a good idea for young birds or chicks.How long does it take for baby birds to fly?The nesting period is different for different species of birds and is highly dependent on the nature of the nest that parent birds build. A nestling born in an open nest is often urged to leave its home early since the parents are mostly anxious about the safety of the young brood. Nestlings born in a concealed or hidden nest, on the other hand, only leave their nest after a couple of weeks after they hatch out of the eggs. This allows the nestlings to be able to develop completely so that they can fly away instead of having to tread the ground in dangerous areas while they are too young for such endeavors.Understandably, young birds feel safer when they are in their nests. Parents raise their young brood rather closely and give them ample food. Hence, it is natural that the fledglings would be unsure of ‘fledging’ and consequently leaving their parental home. However, this process is of taking the charge of feeding themselves and starting their own life from scratch is just as important for birds, as it is for human beings!How do birds know the right time to fledge?Parents build nests during the nesting season and prepare for eggs to be laid by the female bird. Once eggs have been laid and the incubation period has passed, hatching occurs. Understandably, hatching refers to the act of baby birds emerging from their respective eggs and being introduced to life on planet earth. However, the life cycle of a young bird gets much more complicated and elaborate after hatching. After a young bird has hatched out of its egg, the male and female birds go through another process of incubation since altricial birds are born blind and featherless. Hence, the parents incubate their newborns and feed them till they have learned to manage their own body temperatures. Fledging and its timing varies largely between the different species of birds and the nest in which the baby bird is born. In the case of songbirds, parents kick their baby birds out of the nest way before they learn to fly. Flight feathers, in the case of songbirds, develop in about three weeks of them being born. Blackbirds, on the other hand, can fledge at the age of around 13 days. This period of around 13-14 days gives them enough time for the development of flight feathers - which is the first and most major indication of a baby bird being ready for taking flight.On the other hand, precocial birds such as ducks and geese are born with some feathers and since they do not fly, they can leave their nests almost immediately after the chicks hatch out of their respective eggs. Hence, they do not need much help from the adult ducks or geese of the family in terms of feeding or survival.Institutions such as the Cornell Lab of Ornithology observe that parents of different species of birds have different instincts as they let their chicks leave the nests. These instincts can be based on if a predator is nearby, or the understanding of whether or not the baby has developed wings for flying away. Fledging and how soon or late it takes place is, therefore, a largely subjective matter.Which birds fledge later than others?Some male and female birds build their nests on the ground or conceal them in a cavity. In such cases, the nest is protected from predators for at least a few weeks and hence, the adult birds can concentrate on the food that they give to their brood instead of worrying about their safety. Such parent birds also do not show the tendency of kicking their chicks out of the nest before the wing feathers have grown completely and feed them whole-heartedly.However, a young bird born to parents that built their nest in a rather open and unguarded area is likely to be kicked out within a week of being born. This is because each species has its own traits but the one trait that remains constant is parent birds wanting their babies to not become food for any predators.Why do birds leave the nest before they can fly?Some baby birds are urged to leave their nests within a few days of being born. This is because there are many species of birds that focus on emptying the nest after the first brood is born. The first brood needs to find its own tree to inhabit and figure out what it can eat since the nesting parents would already be preparing for the second brood at that point.Another reason for baby birds having to leave their parental homes soon is that after the first few days have passed and enough food has been given, each baby bird starts to become noisy. This opens up the possibility of a predator finding the nest and destroying it completely.How do young birds know when to leave the nest?Altricial and precocial birds have their own instincts when it comes to the time around which the young ones should fledge. While some nestlings leave within a few days of being born, others run the risk of getting injured or even killed if they are not kept warm by the parents during the first few days.These instincts are mostly based on the development of flight feathers and whether or not the bird is ready to find its own food.Did You Know…Mother birds sleep in the nest with their babies to make sure they are protected and warm during the night.Baby birds never leave the nest at night since they don’t have night vision.Young birds leave the nest when they start developing flight feathers.It takes at least a few weeks for baby birds to fly independently.Some birds fledge later than the others since each bird species is different and the rate at which their feathers grow also varies greatly.Here at Kidadl, we have carefully created lots of interesting family-friendly facts for everyone to enjoy!
