I think the proper term here is Cumulus erectus

Loooove Northern Flickers! I really need to get a feeder.

There has been a single Pied-billed at one of my local birding spots. We've started referring to him as Philip.

I very seriously started spouting facts about titmice at work after listening to the Science of Birds pod about them. That got a lot of laughs

I can't wait to point them out to non-birding friends and be accused of making up their name 🙃

Indubitably!
