Why are the squirrels constantly chattering around my yard?

The babies are teenagers now and are gossiping mercilessly about the ones with less fluffy tails.
At my house, the gentle, pinkish-grey doves keep the squirrels in line with weird intimidation techniques, so they are not as loud.
Except when they taunt the dog.

I need to get out more….

They are talking about you. One of them peeked in the window and saw you naked and now they are all waiting for their chance to see you naked.

New dog or cat in the neighborhood.

They’re nuts.

They’re squriids.

Some female squirrels come into heat this time of year, others in December. Yours are in heat and they are the ones making noise because of all the males who want a piece of the action and won’t leave them alone.
