Baby bird season is incoming and I’d like to remind everyone that birds do not have a significant sense of smell. Bird parents will not reject birdlets because you have handled them.
If you see smol birbs with few or no feathers on the ground, you can safely put them back into their nest, bird parents will still care for them.
If you see smol birbs with some or most feathers on the ground, please leave them there, as bird parents are probably nearby watching and feeding.
