They're called birds.
baby birds do :)
Baby birds mostly fledge or leave the nest in mid/late Summer.
The entire process from the time the mother bird lays the eggs until the baby birds leave the nest varies depending on the species of bird. Some birds like hawks and herons keep the babies around longer than other birds like hummingbirds.
I wouldn't. If the nest is moved, and with human scent on it, the mother bird will usually abandon it. Leave it be until the baby birds are kicked out to fly on their own. Then it can be removed.
Birds typically leave the nest when they are fully grown and able to fly, which can vary depending on the species.
Most birds look very like their parents by the time they leave the nest.
Magpies and woodpeckers.
The siblings in a birds nest are called a brood, and when a bird sits on her nest it is called brooding.
The best thing to do is leave it alone. Dont take a risk to harm the bird to kill the ants. The mom or the baby bird will figure out what to do. Ants might even be food for the baby bird.
Te specific study of the birds nest is calle "ornithology".
no they feed it to the others
