In the zoo, bears and badgers become sluggish and fit to sleep. The hardest thing is animals that migrate to the south in the fall. Geese, swans, kuliki and ducks are worried, trying to “get together in a pack”. African antelopes rush through the corral and mumble. But this behavior lasts a month and a half, then the animals calm down.
