I cannot see anything that stands out with regards to the coloration you mentioned. Looks like mine.
I will ask, do you think she was stuck where she is in the photo?
I only ask cause today I had one in an almost identical spot, I thought he was maybe dead, but moreso I thought he was stuck in between these two small branches. No arms to fight his way out and I thought he was not doing good. I grabbed tweezers and separated the two sides enough and sure enough he took off!
So maybe in your case she just landed there, but perhaps she got stuck in between there? Just throwing it out there. My situation was darn near identical only it was an even tighter squeeze and I thought for sure had i not helped my horse he would not have survived. Sorry for the loss.
