Pretty!

  Shaky, are you going to have the cam on night roam soon? 

!!! Juvenile still on site
September 05, 2013 - Toronto - Canada Square Building - Yonge and Eglinton

Marion Nash Reports:

I was out on Thursday 5th September and as always glanced up at the Rio-Can building and found a large *lump* on one of the uprights on the top floor west end of the building. I had no binoculars with me but had a suspicion it was one of the juvenile females. I finally walked to a spot from which I could see her chest and it was definitely a juvie female. Not sure which one. Anyway she flew away and I was on my way home when she re-appeared much lower down on the building. I was on the north side of Eglinton and almost under her and I waited and watched. Wily bird! She flew south along the west side of Canada Square and around the south end to Yonge Street. I waited and sure enough she flushed the pigeon flock from the building south of the CIBC building and chased them across the intersection. The pigeons at the intersection have learnt their lessons well and now fly quite low to avoid becoming peregrine dinners!

She flew back onto the Rio Can building and sat for a bit then chased another pigeon in front of the building towards Duplex Ave but went over the roof of the gold building on the corner and disappeared from view. At the same another peregrine came from the east, struggling against the wind and perched on Rio-Can. I am not sure whether this was the adult male or the juvie male. From what I could see I think juvie male but am open to correction.

At least one juvie still in the area. I am wondering if this might be Imagine as she was the largest at banding time.

May as well point your finger at the guy and say "No No!"   

 

RM & T at home today, by nycbird!!     Thanks

I'd like to think this is Beauty & DC flying together but it's probably bugs!

Indy Froona nesting in Wisconsin!!     Lots of pics and story!

She caught a juvie gull!

I had the honor of meeting her when I was there. Yes, a very sweet woman. So sorry to hear of her passing!!

Hope your doing well Helen and have a very HAPPY BIRTHDAY!!

Sick humans!!    Can't even imagine the suffering they went through!!

  Hi Donna 

That would be "Shaky2 LOL  Hi Nora!! 

Interesting.  Like with dogs, they go on sight besides smell.  I had an Old English Sheepdog clipped down and the neighbor dog always loved playing with her.  The cat liked her.  The cat ran and hid when we first came home and the neighbor's dog growled at her until they got close to each other.  A neighbor up the street here raised cockatiels and they definitely knew if a person was "their person" or someone they knew.  I agree on the peregrines as far as vocalizations also.  Interesting Shaky!

You referred to Donna as Shaky. You made her dream come true.

   LOL Shaky the 1st!

Seems the juvies stop there on their way out!! Nice, thanks Lisa!!!!

[contemplating how PFs recognize their mates]

Noticing nuances: contemplating how PFs recognize their mates

A couple albums ago during a discussion about Mo and his progression from his injury and in re-bonding with Mystic, a question was posed as to whether or not Mo’s stained feathers on his wing may have had something to do with Mystic’s rejection of him post-release. Although we’re not aware of any specific research about this possibility, we’d like to address this query in terms of what we’ve observed and understand about a peregrine’s recognition of one another.

We’ve seen peregrines posture and vocalize in response to an intruding peregrine that we spot only because we see the peregrine looking up and the intruder is high enough to be a speck in the sky to us. Just as we as human observers notice patterns and colors for bird identification yet can learn to pay attention to subtleties of flight (including: the “Beethoven’s 5th� flap, flap, glide pattern of redtailed hawks; the “on a mission� direct line flight of merlins; the “fingers� noticeable at the ends of an eagle’s wing tips as the eagle soars; the “V�-shaped/dihedral pattern and tilting in the wind flight of turkey vultures; the faster flaps of accipitors like cooper’s hawks and sharp-shinned hawks; and the cupped winged soaring of red-shouldered hawks, etc…) peregrines are thought to be tuned into subtle nuances of their mate so that they can recognize them in flight at a distance. We have to believe that their detection skills are so much more refined than those of the best of human observers, in addition to having exceedingly better eyesight than us. So, whereas we can learn to tell one raptor from another by their flight, it seems that peregrines can recognize individual peregrines by their subtle differences in flight.

Further, we have learned to recognize intruders even when their markings are similar and the leg bands either can’t be seen or the bird is un-banded because an intruding peregrine shows different patterns than resident birds. The standard perches chosen may be different and/or a new bird acts unfamiliar with the set-up of the site or surroundings and may try to perch where there is an inadequate ledge for perching. Again, if we can notice such differences one can only imagine how obvious it is to a peregrine who gauges so much about his or her survival and reproduction on the recognition of a mate versus a threat to the territory.

We did have an interesting experience at the Tower East site in 2010 that we posted about back then on CMNH. The resident female at the time (Diana) went to a rooftop and bathed out of view of the resident male (Stator). When she flew back toward the nest building all wet Stator began to attack her, first in the air and then by buzzing her as she was perched. She reacted and vocalized, but Diana had to endure his aggression for several passes before it seemed to “click� to Stator that it was her. We’re including some shots of this sequence in the album—you can see that Diana looked markedly different when wet (much darker with feathers sleeked to her body). Yet it didn’t take her drying off for Stator to start to recognize her. We assumed that there was some other recognizable feature and/or their verbal or nonverbal communication with one another. Diana did vocalize as Stator dove at her, and research indicates that other species of birds recognize one another through their individualized “voice� even when they seem to making the same sound.

Another experience that seems related is represented by several years ago when we attended a banding in Toledo where Stryker was the resident female. Stryker had a distinguishing mark over her right eye where a battle wound healed, but left a pigment-less white patch of feathers over her eye. From what we heard, Stryker got into the battle, but retained her site and the same mate (Angus), from that point on being easily identified by observers by the white streak over her eye. There were no reports of any alterations of the relationship among the pair, so there was no indication that the physical change impacted their interactions (although it’s not clear how closely monitored this pair was and we were too distant for regular trips to that site).

Once again, we welcome any data or research that adds to this discussion, but based on what we have seen and know to be true we believe that peregrines use a variety of factors to determine the identity of another peregrine including, but not limited to: flight style, markings, habits/patterns of perching and posturing, and vocalizations and/or “voice� fluctuations. We would suspect that even if Mystic were initially thrown off by Mo’s stained wing she would recognize him in other ways (much as Stator did with Diana even before she dried off from her bath, or as Angus seemed to recognize Stryker following her feather variation above her eye).


In a comment on FB they mentioned DC swooping on Beauty:  Chad Steele Dot Ca And Stator appear to have something in common! Males don't physically tackle females.. like females will males, but they swoop and harrass them...Dot Ca shows us that!!

Wilmington Falcons
I received some sad news about "White" from Craig Koppie today...

"Sorry to have to report that one of the 2013 Wilmington juveniles was found dead on September 4, 2013 in Pennsylvania. He was recovered at the Lehigh Valley International Airport near Allentown apparently struck by an aircraft, possibly around 8 a.m. A straight line distance between Wilmington and the airport is 65.71 miles. I am sure he traveled many more miles since leaving Wilmington to this final destination point."

Hi there. We don't have any major updates, we just wanted to break the silence and calm any nerves concerning dad peregrine. He's doing just fine. His injury will prevent him from returning to the wild, unfortunately. He's still with the rehabilitator and we are in the process of selecting a permanent institution in which he will become an education bird!
