I’m.in NY.
Mainly it’s rubythroats here.
But we’ve had some oddballs the past few years that just don’t look...right.
And they are very mindful of windows and cameras.
So trying to get pictures, you get a colored streak on the image.
Still wonder what that one was, I swear it looked yellow and had a largish splayed tail.
Which doesn’t match anything normal to NY.
You may have a wanderer. How fun!
Not sure what it could be.
A picture is a great help.
