The one was determined to eat despite the rain which was falling rather heavily. You can see how wet his tail is and somehow, he has it, somewhat, shielding his head.
This one stayed under the bushes and only his tail became wet which was drying off in the photograph.
And there is the squirrel who wouldn't get wet for anything. Soon as the rain started to fall, he ran under the car and sat on top of the wheel watching the very wet squirrel continuing to eat.
Interesting rodents!
