....is a great site [you have to sign-up] for meeting all sorts of experienced birders, who may have an idea for you.
Weirder than anything.
Every time I’ve tried to get a pic, either the rubythroats start a feeder battle, or the oddball notices me trying to focus on him.
Result is the same every time.
This year we’re short a tree.
The hemlock came down during hurc sandy.

Oops.

Not exactly the size you expect when you finally see it sleepily sitting and watching you.

“Medium sized” is roughly crow size to bluejay size.
