Is it possible for any creature to stay on an altostratus cloud without falling down? what are its limits?

I am working on a story. i want to know if is it possible for creatures like snake, eagle, vulture to stay on an altostratus cloud without falling down. if possible the limits on how much force and pressure it can withstand.

Altostratus clouds are mid-level, gray or blue-gray clouds that usually covers the whole sky. The Sun or moon may shine through an altostratus cloud, but will appear watery or fuzzy. If you see altostratus clouds, a storm with continuous rain or snow might be on its way. Occasionally, rain falls from an altostratus cloud. If the rain hits the ground, then the cloud has become a nimbostratus.

Thanks for your answers
