Yesterday at Pitt Peregrine Fledge Watch the weather was beautiful and so were the peregrines.

When we arrived at 4:30pm two juveniles were on the nestrail: the male (Green Boy) and one female (Yellow Girl). Notice their size difference!

We figured out which female was topside by noting Blue tape on the bird in the nestbox. She exercised her wings a lot.

Meanwhile on the nestrail, one of the juvies walked all the way to the right to perch above the nestbox.

The second juvie flapped and ran to the righthand side — using the nestrail like a runway — and was on hand for Ecco’s food delivery. (Notice the excited wings-open on that juvie!)

Down in the nestbox Blue Girl missed out. Her parents were delivering food to the nestrail, not to the nest, so she would come topside.

Blue was still down there when Green Boy came for a visit at 7:25pm and discovered the fun of climbing the snapcam wall.

You’d think he was posing, but no. He’s looking over the nestrail.

This morning Blue was done with feeling left out. At 6:38am she climbed up to the nestrail …

… and now the nest is empty.

Join me at Schenley Plaza today at 11:30am – 12:30am for Pitt Peregrine Fledge Watch. Bring binoculars if you have them. I’ll bring my scope.

Will one of the juvies fly today?

p.s. At 8:10am Ecco came to the nestbox for a respite from the “kids.”

  1. Thank you for this summary of yesterday’s activities- what a great time to be a falcon! Last night after dark I checked the nest to see if Blue was still alone. A sibling ( Yellow?) had come back to the nest to keep her company. ??

    1. Kate,
      This morning I stopped at the boat ramp in Sewickley to see the nest box there. I have been suspecting that there may be a fourth chick and was able to confirm my suspicions. I clearly saw four chicks standing side by side at the edge of the nest box. I posted pictures on ebird.
