On the photos thread I had posted some baby pictures of Thunder and while myopically peering at them, it looked to me like her eyes were blue? So I asked Donna about redtails and baby blues.

She wrote: "Yup, a very deep blue which often looks black in photos because of the light, then the eyes, usually by fledging time, lighten to a paler blue, which goes to yellow gold, then deep gold and by the time they're four their eyes are completely brown. So to "age" a redtail: A one year old has a brown tail, a two year old gets a red tail, then you can tell a three and four year old (kind of) by eye color."

bobdmac: On redtail males smaller/female larger issue: Professor John Blakeman weighs in on the subject on Donna's blog site (http://palemaleirregulars.blogspot.com/), and writes: "But the fact remains that the smaller male must still feed his larger mate and any number of newly-hatched eyasses for the first two weeks or so after hatching. During that time, the female must remain on the nest and keep her hatchlings warm and dry. The male has to feed that entire family, but he's smaller and more limited in what he can capture and bring up to the nest. This doesn't seem to be a survival advantage for any party.'Tis yet an unsolved biological quandary, at least for me." and the ongoing discussion goes on with Donna weighing in too. Too long to post here, but interesting. It reminds me why I think the best scientists know that they do not know everything or maybe even much. :-) Learning, learning, learning.

Me. Again.
Donna has just posted a report on the Rochester peregrine falcons that you might find fun --

http://palemaleirregulars.blogspot.com/

It also includes some links to more photos of the Rochester peregrine eyasses.

I checked in on the Waukegan falcons a little bit ago & got a great screen capture of the five babies.  Just had to share, they are soooo cute.  Sunday afternon nap.  Usually I would edit just the pic, but I thought I would leave the browser showing so you can see the link to the website also.

I love this nest box and the view is spectacular, for this falcon family, Mama's feeding them now :)

Weeyin: Let me add my thanks for this website. The sound just makes it so much more intimate. Looks like one of the four eggs didn't hatch.  Also, I wonder what that nesting material is. I'm assuming it was put there by the folks who constructed the platform. It seems to be made of rather loose, shredded matter, something like rubber? I see when an adult settles in to brood the babies, he/she sort of digs down into the floor material. Anyway, thanks, I love it!

Love all the updates on the other cams. Here's an interesting report on the San Jose crew, which includes the mom (Clara) driving off a red tail hawk!

Hello All,

It was fantastic to meet so many folks on the garage.  I finally got to put
faces and
personalities  to emails.

We arrived around noon and got to see Clara return with a Pigeon. She was
plucking like
crazy and seemed to want to have a few bites before dealing with the youngsters.
Apparently this was not in Mercury's plan. He took off and flew to the top of
City Hall, and
landing,  on top of some Satellite thing.  He began wailing  g for Clara.  Clara
flew to the
East Side the roof and he flew/jumped down  to  meet her.

Evette and a bunch of us took off on a little field trip to the East side of the
City Hall and
we got the joy of watching Clara Chase off a Red Tailed Hawk.  Man is she fast
and wow
does she have some amazing vision. Met Mark (?) and another woman.

Went back to the Garage via the MLk library were we checked out the Photo
Exhibit. If you
have not been I highly encourage you to go. It is on the 4th floor.  Fantastic
Photos.

Just prior to leaving the Garage we watched Clara escort Mercury back to the
nest. Very
touching.  That little guy seems to be doing quite well now.


A few things impress me about these birds.

(1) the height at which they fly until you see I don't think you ever quite get
it. They are
almost specks in the sky.
(2) the speed
(3) How loud they are. You figure were quite a distance down and we could hear
them.
Even in front of the MLK Library the could be heard.

**** Most importantly  I'm impressed by the dedication of the volunteers and
paid staff
who run around ensuring a safe landings and flights and their entire future.


To quote Light Eagle "It is a good day when in the presence of Peregrine."

Take Care,

Corina

Re: Observer catching screen captures of our redtail family flying around the tower at night.

Sunday night on her website, Donna posted:
"I've sent the night flying question off to John Blakeman for his take. I have seen Red-tails fly in the dark but in my observations their flights were for very specific purposes. For instance changing roost sites if they felt they'd been discovered by someone unknown to them or a quick stealth trip into a nest, seemingly hoping that the move would be undiscerned. But then I've never watched a Red-tail absolutely all night so who knows? I haven't seen them go about lengthy business in the middle of the night. Though I just read an article about species who we'd thought were completely diurnal, which when their current main food source became something that was nocturnal, they became nocturnal as well."

Blakeman is a Professor of Biology at a Ohio university, and a falconer. He is the go-to guy for redtails. He was also part of the team, with Donna, Jeff Kohlbrunner (photographer), the NYC Audubon society, and the co-op building where Pale Male's nest is situated, which made the assessments, recommendations, and changes to Pale Male's nest this January.

Thanks bobdmac for another update on San Jose's falcon family, it's obviously an amazing thing to see first hand as the folks decribe in their awsome post, sound's like they were thrilled to bit's.

Bobdmac, Ahha another falcon chase's a redtail hawk off her territory/boundaries. This is one lucky redtail hawk, who live's to fly the friendly/unfriendly skies again!, though next time redtail may not be so lucky....I'm rooting for them all......Falcon's & Redtail hawk's & their offspring :)

Bville, I'm glad you're enjoying this new falcon family I love watching them & other's too. I did see the unhatch egg still in the scrape, but Mama will not discard the egg until, as only a falcon Mama can tell

She still coninue's to tuck the egg underneath her, along with her wee fuzzy offspring (growin' daily!!) Their (nestbox) scrape is covered with small stones & pebble's, no cozy twig's/branch's for these raptor's. Later on the scrape will be strewn with feather's from their parent's daily hunt's/feeding's, and the scrape look's like a feather mattress....a wee bit of irony for the peregrine's and their offspring's :)

Weeyin', glad you're enjoying the San Jose updates. There's even a woman who flew out from Missouri to watch.

I've been following the falcon cam that you posted, and I've really enjoyed the sound. It really puts you right there, doesn't it?

G' Morning folks. While waiting for cam to become connected again. I'm watching video's of Thunder's family, also I came across this eagle's family nest in Deta, B.C. If you type Delta eagle nest in search & click "Flip the Chick"  it's posted by Hancock Wildlife Fdn., it's another one for my all time favourite's list!! :)

There's a clip of parent who's had enough from one of the eaglet's and it get's time out or chill out. It's very funny & according to the folks blog this is the first time, they've seen anything like it, on any eagle's nest's they've watch!

I can't help myself as I'm watching this parent saying "Enough Already"!!! anyway again I hear my own word's speaking for eagle & eaglet's as they interact with each other. This wee brusier even does a face on, bobbled head talk back to the parent, so funny, so please add you're comments, thought's or word's to what you think? was being said, between this wee eaglet and Mama/Papa? I'd love to read them! :)

Bobdmac..just as well you can't see me now, I'm turning "Green" with envy!! :)

The sound does let us hear the wee peeper's in real time, really nice, though when the back ground noise level get's noisier, I hit the mute button. The osprey camera's in Loch Lowes and Loch Garten, also have sound too, but adult osprey's vocalizing, have a high pitch shrill peep's. Remind's me of the skirl from the bagpipe's, it sound's a wee bit like that to me and it drive's my feline's catty, so while listening to the raptor's peeping and my cat's undecribable havering noise's. It's mute button again! :)

Those of you who are watching the nest cam in Waukegan of the peregrine falcons, all five babies are not there today.  There is a sign in the nest, but I can't read it.  Some of you, please tune in to the site and let me know if you can read what is says. Thanks.

Redfinch, I'm looking at cam now and I see the eyas'es and the sign far wall of nest box, say's The Field Museum-Mid Western Generation? is that the sign/small logo at left corner look's like a picture of the sun's energy?

I can still see the eyas'es one a the very back, with another laying flat near by, also there's another's side profile closer to the camera and the last one is at the back, just below the sign.

I hope that help's :)
