While spring is known for baby birds, many species nest throughout the summer and even into fall.
The baby birds, or “fledglings” once they have feathers, are often found resting on the ground as they learn to fly. While it may appear that the babies are distressed and alone, this is rarely the case.
Fledglings spend days on the ground—sometimes as long as two weeks—and their parents are close by. Only seek help if the bird is injured, or perhaps move it to the shade if it appears overheated in the sun.
Your scent won’t disturb the process.
Otherwise, give it time, and the parents will return to teach their young to take flight.
