Hi Nancy :
Can you post a pic on a dark background (same type of shots) but so we can get a clear, more defined pic of just the birdie?
I would have no idea if it is a wren....to me, it is just a bird
Thanks, look forward to those new images. Clear glass is so hard to take a picture of. You could even just use a black shirt or something.....I have done that

as a Simple solution. Bunched it up at the back, or resting against something so the glass item has a black background
