Got a report from our bander Mark Heaton that Velcro a female produced in 2016 at the Yellow Pages nest site in Scarborough has been seen in Royal Oak, Oakland County Michigan on March 12th 2021.
Sadly, I have bad news about the status of the Scarborough nest site as of my visit this afternoon.. Again a big thank you to Petra security for spending the time with me today as we meticulously checked all eight ledges for any evidence of a hatch.
The first clutch of three eggs still remains, still abandoned, and now quite sun-bleached almost pure white and look more like white chicken eggs. And to be very clear,, there are NO chickens here!
As we walked around the entire upper elevation of the building to check each of the eight ledge pockets, there was absolutely no visible evidence or sign of any “recent” peregrine activity,, all lacking the typical body-part remains of left-over prey or any fresh blood staining on any of the upper leading retaining wall ledges or ledge pockets. This along with the fact that there was no evidence of any fresh white-wash tells a story in itself! A strong indication that there has been no “recent” peregrine activity.
As we finally worked our way around to the ledge that has the more recent “second clutch of 4 eggs”, we quite expected to be greeted by at least the resident adult female, (which has been Linn from Rochester NY all these years), who was clearly identified during my last visit via her leg bands,, but sadly did not happen. Never have I NOT been “greeted” by Linn as she is usually VERY AGRESSIVE and always “IN MY FACE” during my visits over the years. Linn is NOT shy to express her displeasure,, and over the past years has become a “FULL CONTACT” gal!!!
Unfortunately, the 4 eggs in this second clutch of eggs remain unattended and have not hatched as of this date. They now remain more than 36 days old it would appear that they too have now been abandoned.
After more than 35 minutes on-site, we did not see a single peregrine! 
I will return one last time next week to re-confirm my observations and conclusion.

At the request of the building management as a result of the recent activity of the grins on their building, I attended the Scarborough nest site to get a better understanding of the happenings and update the management group as to the activity of their resident peregrines. Remembering that my last visit on June 17th confirmed that the first clutch of 3 eggs had failed and that the resident adults had abandoned their first clutch of three eggs.
Well, did we get a surprise when as we entered the upper rooftop walkway, as we were both aggressively persued and stooped by the resident adult female (non-other than Linn - clearly identified by her black-band 91 over V) the long-standing adult female)!!
As we moved around the building checking the 8 nest ledge pockets, I have confirmed that the original first clutch of 3 eggs is still there unattended on the southeast corner ledge.
That said, as we moved around the to the North-east corner column checking each ledge, the intensity of her aggression magnified 10x fold and we now know why! a second clutch of 4 eggs was observed in the nest pocket on the North-east column! *See attached photos.
Given the timing of my last visit on June 17th, (only one set of eggs that failed) and no others on any of the other ledges,,, and in consideration that there are NOW four new eggs on another ledge,, I suspect that they were layed sometime between June 18th and June 22nd,,, with full-time incubation starting around June 23rd. With this in mind,, if they are in fact **fertile and the incubation goes well, we should see a hatch in 33 to 35 days as of June 23rd,,,
Expected hatch around the week of July 26th to July 1st.
** It is important to know, that I did NOT see a resident male during this visit, and still have a question in my mind as to the presence of a resident male on site. If not,, these eggs may not be fertile.
Stay tuned…….
Mark checked on Lyn today and found 3 eggs still on the nest no hatch. He also has not seen a male on site this spring at all and Lyn was not there today and did not fly in to challenge him on the roof. Looks like the nest has failed again this year. It may be that she has no mate this year and the eggs were not fertile. We will pop in to check on her again in a few days.
Mark went to have another look at the nest and there are still 3 eggs no hatch as of yet.
Yes Lyn is still on site however I can’t confirm who the male is yet. There are now 3 eggs and we will be going back soon to check for a hatch.
She’s in great shape. I had been seeing a pair hunting together off and on for a few weeks and wonder if she’s one of the banded birds I had been seeing. I was never able to get a good look at either bird’s band combo, so it’s hard to say. I have a contact with the Michigan DNR that has records of all of the breeding pairs in the area and I was going to check with her to see about your bird.
All raptors we trap and relocate are part of wildlife control operations at Detroit Metropolitan Airport. She was trapped in a swedish goshawk trap and relocated to state land in Chelsea, Michigan. Getting her away from the airport environment is the safest thing for her as well as the aircraft.
Please let me know if you have any other questions. Happy New Year.

A quick update on the Linn at the Scarborough nest site. Incubation continues with her second clutch of 4 eggs.
With some blustery cool winds, (and still some very unreasonable cool temps), Linn was still down hard on incubation duties and her mate was still very much providing air cover during my visit today.
Stay tuned, and we’ll do another check next week to see if there has been a hatch.

Despite the fact that the pairs first clutch of eggs had earlier failed,,, there is no reason to stop trying,, and so it is for the Scarborough Milner nest pair!
Today’s check-in visit yielded some very good news indeed with presence of a second clutch of 4 eggs!!
Yeeee gads …. we’re going to doing fledge watches and bandingss all summer long!!!
Stay tuned, as it would seem that Linn and her mate is not quitters!!
