It's still too early to tell if Rosie and Bobby are going to use the new fire escape location for next spring's brood but their activity today was a real eyebrow raiser.
The 'nest' has a lot more material on it since the last time I saw it and Rosie went through great efforts to bring a new and heavy piece to it today. Bobby showed up and help fortify and build up the nest.
Bobby appeared. He is seated on the right:
Rosie working on the nest:
A window washer stepped onto a ledge at the same level as the fire escape but never saw Rosie:
It didn't take long for him to finish up then go back inside.
Rosie flew from the nest and to the railing after a few minutes:
She flew between buildings lining Mercer Street 12 minutes after landing at the base of the water tower:
I found her on a new perch located two blocks further east:
She dove down then came back up with a fascinating piece of metal and spring:
She then hopscotched to a couple of different perches before bringing it to the fire escape:
She brought the material to the nest, set it in place, then went back to the railing.
She panted for a couple of minutes. The piece she had carried must have been pretty heavy and unwieldy for her and tired her out a bit.
She took to the sky again:
Heading southeast again:
She flew back to the fire escape after a couple of minutes:
Bobby flew right after her (he is on the right):
They both worked on the nest for several minutes together:
I hated to do it but I had to leave the two for the day. I left with Bobby still working on the nest material and Rosie preening on the railing:
