I’m shaking my tail feathers

And: Bats

Sat in the house (two before the current – about 500 yards away)

I’m in my chair, fireplace mirror to the left, I can see a bat flying up and down the stairs, to the right. Bunny Man doesn’t believe me. Max, the GSD, starts barking.

A BAT!  Bunnyman caught it in a colander with newspaper and released it

I will  go with Dan. Crazy frog

Not sure about posting D

Don’t want @Hunnybunny shaking a tail feather and doing her knee in again.  Not if she has already done  that with Agadoo and the birdie song

Think I’ve been poking too many bears this week.

Anyway C is for Convoy and since Rubber Duck gets a mention I think I know what you have lined up for D.

Can’t wait until D

@BrianN   B is for birdie song (shall I, any more shenanigans and I will)
