Uit New Jersey ook geen leuk nieuws. Eentje overleden na de eerste vlucht en eentje op straat terecht gekomen en naar de opvang gebracht. Inmiddels weer terug op het dak. Hoop dat de andere twee het verder redden.
July 6, 2009
We have some good news to report. Local nest watcher Bonnie T. was out on Saturday, July 4, and recorded her observations:
"I was so glad to see the third fledgling get a food drop by both adults just over the scrape this morning around 10 AM. I was about to give up on seeing anything when I heard the kakking of a young one who wanted brunch. He was flying very well between the terraces on top of the building. And I do believe he was perched on the NE top pillar just prior to the food drop."
These observations indicate this young peregrine, the male of the brood, has indeed fledged successfully. One of the females (A/12) died after fledging last week, and the other female (A/11) ended up on the street. She was treated at The Raptor Trust and will be released back on the roof this afternoon. We are certainly hoping the remaining two will take their time before trying to fly in the canyons between the buildings!

We apologize for the recent video outage. After checking all the controls on our end and finding nothing wrong, we determined it was on Verizon's end, and -finally- it was restored. In the down time, we lost some good viewing opportunities of the young on the roof.
We have this news from nest watcher Bonnie T.:
"I went down on Sat. and Sun, June 27 and 28, and was treated to eyases bouncing and sleeping on the ledge. Both parents are keeping a close eye on the young. They position themselves east and west or in the middle depending on where the eyases are."
We have other observations from Michael G. from Sunday, June 28, street-side at Hudson and Columbus Avenue:
Around 9:58-10:10 AM, observed both adults soaring over 101 Hudson & adjacent buildings. They made several fly-overs of 3 eyases on rooftop (whose begging cries were clearly heard).
10:02 AM, saw a possible aerial prey transfer between adults. Both birds were flying towards each other (1 from PATH building, 1 from 101 Hudson and vocalizing). They appeared to make brief contact, then separated. 1 adult flew back to 101 Hudson and appeared to land near nestbox. The other adult circled near 101 Hudson before making its way back towards the PATH building.
10:13-10:25 AM, saw 2 eyases sitting on the ledge stretching their wings and flapping, with both adults perched nearby (1 on the ledge between 2 eyases, the other on the corner parapet near nestbox).
10:30-11:15 AM, adults made occasional circles over 101 Hudson and PATH building. At 11:20 AM an adult flew N from corner parapet near nestbox and launched attack on pigeon. Both birds disappeared over a building. Adult re-appeared a minute, flying leisurely SE over to PATH building, but did not appear to be carrying prey, so no evidence of a kill from this attack.
11:15-11:45 AM, observed 1 eyas perched on the ledge next to nestbox. Eyas defecated once and did some wing and tail stretching but otherwise remained in place.
These observations are evidence of the young getting very ready to fledge. Just two days later, on Tuesday, June 30, one of the young did take flight. For all the reasons that flight is precarious for young birds, and primarily inexperience, he collided with a building just a block away, and was found dead. Yesterday, July 1, a second bird took its first flight from the rooftop, faring a little better but did end up on the ground. Fortunately, the bird was picked up and one of the engineers at Mack-Cali transported it to our staff, who got it to The Raptor Trust last night. We'll provide updates when we know this bird's condition, but we do hope to get him back to his parents as soon as possible.
We suspect the remaining eyas is the female of the brood, mainly because females tend to fledge 3-7 days after males. When we can confirm who's who, we'll report it here. We certainly hope to have better reports soon.
Peregrines in urban areas do face many hazards, but they are just different hazards than those in more remote situations. One of the benefits to city living is a lack of predators on the young birds. One of the trade-offs, though, is the young birds have to learn quickly how to negotiate the man-made cliff environment. We'll keep our fingers crossed. We thank all who are watching out for these birds.

Nee, ze heeft waarschijnlijk een prooi op, die beschoten is geweest.Barbara schreef:Dus ze is waarschijnlijk gewond geraakt omdat er eerst op haar geschoten is?Heb ik dat goed begrepen?
Dit lees ik in eerder verhaal op die site.
De hagel kan via natuurlijke weg eruit komen, maar als dat niet gebeurd kan de valk ook een (lood-)vergiftiging oplopen.
@Roosje: ik wist niet dat er ook een filmpje op stond, zal zo eens kijken.
