Wren Family

Couldn't believe my luck getting the whole family in one shot today! I'd been watching for a while and was about to take the picture, when the second parent arrived :-) I wish I could tell them apart but not sure how easy that is.
They must fledge tomorrow, they are getting sooo big and I'm worried they're going to fall out in their eagerness for food, or even worse, get pushed by their siblings accidentally :-/
Pete has put a trampoline type structure to soften the fall should this scenario occur!!
