This kitten is crying out for help when it can't find its mother.

Kittens frequently express their emotions verbally when they're upset or lonely. There are a few things you may do to assist a kitten that is calling out for its mother but is unable to locate her:
Look for the Mother: Make every effort to find the mother cat. Reuniting the kitten with its mother is the best course of action, and she might be close by.
Observe from a Distance: Mother cats occasionally let their kittens brief periods of time alone. It's preferable to let the mother cat tend to her kitten if you spot her returning.
Establish a Safe location: Provide the kitten with a warm, safe location if you are unable to locate the mother. Make use of a tiny carrier or box with cozy bedding.
