They are both part of what an animal does during the cold season. I believe there is a third, where the animals don't do anything and live throughout winter, so they're both what an animal does in the cold season. Hope this helped.
An antonym for migration is immobility.
No. To migrate is to move. Hibernation is to sleep through the winter months.
hibernation
animals do both
The nouns in the sentence are hibernation and migration, compound object of the preposition 'by'.
migration and hibernation

Ther are not the same obvious and I 'am a kid.
Hibernation is remaining dormant in the same ecosystem. Migration is travelling to a differnet ecosystem. These are usually caused in the winter because of the drop in the climate's temperature.
phiysical because it helps it
do you mean migration?? And if so migration is moving to a different area birds migrate south for warmer weather in the winter months. Hibernation is what bears do, they just sleep all winter.
Estivation - a state of dormancy similar to hibernation, except it is used in the summer ...
