This pair Romeo and Juliet have raised several chicks. I contacted the powers to be on the fact that she has not shown up yet and here is the response.
AEF-NEFL If you are interested in the dated nest activity over the past eight seasons, here is the link to the recorded Timeline. This year, Romeo returned earlier than he has in the past (returning on August 27), whereas Juliet's latest return was on September 16. She should be making her "entrance" any day now!
