Almost certainly, yes, but please DO NOT touch birds' nests.
It's a metaphor because it likens human parents to bird parents. Birds feather their nests in preparation for their young. The sentence compares humans getting ready for their baby to birds getting ready for their babies.
Yes,they will eat their young
baby birds get adult mites from their parents in the nest
Baby birds are born being able to hear. It is their way of identifying their parents who chirp and make noises at them.
When birds lay eggs they usually sit on them and keep them warm. Just like when a human is pregnant, our baby stays warm inside our body. If we freeze to death outside, our baby would die. If the eggs aren't kept at the temperature of the parents they wont be warm enough and they baby birds will not grow inside.
Make sure the parents keep them incubated. If the parents are terrible parents, or if the egg has no parents, then get a good incubator to keep the at the right temperature.
Yes, it's OK to place a fallen baby bird back in the nest. It's a myth parent birds will kill babies that have human scent on them. The parents will care for it if the baby bird isn't ill. Baby birds often end up out of the nest because parent birds "kick" them out due to illness. Seems cruel, but it's how Mother Nature works.
A baby Brown Falcon eats small rodents, grasshoppers, and birds provided to it by it's parents.
Regurgitated food from their parents, which can consist of worms, insects, etc. Please ignore this answer. It was misread as baby birds. Sorry!
Baby birds do not smell, probably not if you had to handle it. Birds fight to survive, many are tossed out of the nest by siblings or adult males.
birds and mainly baby birds
Of course not. A female human can only get pregnant with a male human's sperm.
