TULSA'S KAY AND JAY NEWS AND COMPARATIVE NEST TIMING


Hurrah! News from Tulsa Hawkwatcher and photographer Cheryl Cavert on Kay and Jay of the KJRH Tower nest!


Hi Donna,

As I was driving home yesterday around 4:15 pm, I noticed a hawk-like shape on Jay's favorite high perching pole at the KJRH Tower in Tulsa. I parked and took a few pictures to look at later on the computer - as with the gun-metal grey skies, I could not tell for sure if it was Jay or not. It looked like it was probably Jay and after watching him preen for a couple of minutes, I decided to park a couple of blocks away to the north, a position that provides a good view of the tower without straining the neck!


As I drove to my new position, I could see another possible hawk-like bird circling in closer from the west. I quickly parked and hopped out with my camera and binoculars - and yes, it is definitely a red tail hawk. She circled closer then landed on the KJRH nesting platform. Jay glanced up and also took off from his slightly lower perch, circling around to also land on the nesting platform.

I could see their heads bobbing up and down occasionally like they were engaged in some nest keeping duties. I went back to the south base of the tower and as I arrived, Jay prepared to leave, circling off the northwest towards the Arkansas River. After a couple more minutes of nest duties, Kay also flew off, soaring to the northwest into the treeline Jay disappeared into.

The area in Riverparks (southwest of the KJRH tower) the recent observations of Jay occurred (ie. Jay riding the Prairie Wolves), is now under heavy daily construction. In the past couple of weeks tree workers have also done a bit of tree trimming, including trees I have seen the RTs perched in at various times, as well as removal of dead trees and stumps. However, the big one I have seen a RT and a bald eagle perched on at different times is still standing near the edge of the river bank. So maybe Kay and Jay are enjoying Riverparks a little further north where it is a bit quieter right now.


I will keep looking for further nest/courtship behavior as well as photographing whatever local urban hawks I come across, hoping to spot Thunder!

Go get 'em Cheryl! It's very exciting to see Kay and Jay at the nest possibly considering just what might need fixing up for this season. Thank you for you sightings and photos. Hawk Season is beginning earlier this year now that we know this pair.

I began to wonder just how much earlier and emailed Catbird, of the Tulsa Forum for the relevant dates for Kay and Jay from last season so I could compare them with those of Pale Male and Lola and that of Isolde and Tristan of the Cathedral at St. John the Divine.

Here is a portion with some of my thoughts on the matter from my email.

" As to early... Well, I'm thinking that in Tulsa, you'd need to get your babies out of the nest and well along before it gets too hot and the prey base suffers.

What Kay and Jay are probably doing at the moment is adding to the nest which can go on for a bit. Also Jay has to present at least two nest sites to Kay so she can have a choice. Lets hope she chooses the TV tower!


Some believe that nesting in RTs, cycles with the birth of prey litters. I don't know when there are major births of rabbits, squirrels, voles, etc. in Oklahoma but I'm betting it's before the grass burns off in summer. Pigeons and rats reproduce whenever there is enough food, though in cold climes in winter the young don't always make it."

And here are the stats that Catbird sent back--

Donna,

Both eggs had been laid by March 3 (Thunder's egg laid first, earlier), and Thunder hatched March 31, and Thunder fledged on May 24th.

Catbird

Looking back at my notes and at the "History of the Fifth Avenue Red-tailed Hawks as of 2/23/05 For the Cult of the Pale Male" by James Lewis, I'd say that Kay and Jay are two weeks if not more, ahead of Pale Male and Lola on Fifth Avenue and about a month ahead of the St. John the Divine Cathedral nest.

For Cheryl and the other Tulsa Hawkwatchers, keep an eye peeled for the bringing of twigs. That will become more and more frequent as time goes by. I'd be interested to know if Kay also brings twigs to the nest. Pale Male tends to bring the lion's share of twigs to 927 Fifth Avenue but Lola is the one who tends to strip the bark and gather dried grasses for the bowl itself.

When it comes to Pale Male Jr. and Charlotte, Central Park's Southern hawks, both birds bring twigs regularly.

If you're diligent in watching, you are likely to see Kay and Jay copulating in January. (They make a vocalizationg during the act that sounds remarkably like gulls.) Mark the date as it is usually about a month from our first sighting of Pale Male and Lola copulating to the first egg being laid.

Also keep your eyes on the sky for the courtship display, which will occur before copulation. Jay will do some swooping flights. Then both Kay and Jay will circle, counterclockwise to each other. And as their hormones surge ever stronger usually, first the male will dangle his legs and white thighs and then the female does it. Some birds will then slowly drift down to a perch and copulate.

So much to look forward to! And I know Cheryl will be out there with her camera searching the skies as will other Tulsa watchers. Send us all the news folks, we can't wait!

P.S. At to Thunder, we suspect that in urban areas some juveniles of the previous year do stick around though they are unlikely to be allowed inside their parent's territory during actual breeding season.

Don't despair, during this time of year, we have often seen the bonded pairs flying with other Red-tails high in the sky that we suspect are their young from previous years.

And if there is open territory near that of Kay and Jay's and a handsome male happens along in a year or two to claim it, you never know, the Mom may turn out to be Thunder.

We suspect that Pale Male Jr., Tristan previously of the Cathedral Nest, and the female Intrepid/Caroline of the Riverside nest are either children or grandchildren of Pale Male.

P.P.S. My apologies, due to other responsibilites I'm very behind in responding to email but I'm working on it.

Red-tailed Hawks, Sandhill Cranes, Bluebirds, Oh, and a Cow Part I



I had just come out of the library in Milton, mulling over something mundane, like where I'd left the car or how expensive water is here, when suddenly I hear, "Kheeeeeeee, kheeeeee, keeeee!" Whoa, that's a Red-tail on the warpath. I look up and, yes, there, absolutely, is a Red-tail hot winging it to the north. (The opposite direction to the one above.) I run to the car and dig for binoculars, the camera, anything with magnification.



When I look up again, there are three birds in the sky, very high, circling. More digging. Two look like Red-tails and the other is big, bigger then they are by twice maybe? They go behind the tree. Finally the camera, and I see no birds.



Then an RT comes from the north to south, begins to gain altitude, (photo above), and gone behind a tree again. My next two photos show sky with a very faint totally unfocused bird/blob in the sky. One on the north side of the frame and the other center. ???



Another Kheeeeee! and a Red-tailed hawk goes from south to north.


Then the above bird appears from the NE. Perhaps a large gull, or water bird of some kind, who may or may not have been in on any of this in the first place but is just stumbling through.



And then it goes east.


The next sighting between the trees, may be the original very large bird. Light is gleaming off what might be a white head. She's coming from the south and then circles back toward the south and behind the tree.


A Red-tail comes zooming out of the north and after the large bird with the contrasting head.


Then what looks like possibly two gulls come out of the east. ??? Or a gull and a ?

I finally make it past the offending trees and into someones yard, and nothing. Not a bird in the sky. I look at the times on the photographs. It all took place in under two minutes. No wonder I'm confused.


But that's not all.....


Continue down to Part II. Remember Blogger gets cranky if it feels there are too many photos per post and it was getting very cranky about what has currently become Part II....directly below.

Red-tailed Hawks, Sandhill Cranes, and Bluebirds, Oh, and a Cow


I turn to go, and wait just one minute. In the yard is a tree, a tree with only one limb, alive or dead, a tree that is chock full of cavities! Could there be owls in there? There has to be something, I'm betting. Something or someone who likely comes out at night?

But a friend has asked for me to take a photograph of a particular tree, in prime foliage, with a special shape, out in the country. I've got the directions , but as I'm always getting distracted by the wildlife I'm notorious for "misplacing" myself. I'm going to give it a shot anyway. I head out of town, directions in hand. Guess what?

I follow the directions very carefully, I'm on the right road--eventually, but you know what? There are a whole lot of trees out here and I don't see the "one". I'm just about to turn back...


I glance up to the right, and there is a big female Red-tailed Hawk. Alright! I know to drive past her. Somehow it makes them slightly less ready to flee. But I'm on the right hand side of the road, as is the hawk, and there is no place to pull off. I take a couple shots out the passenger window and remember how one of my cousins who was digging for his camera in the glove box got flattened along with his car, literally with some speed demon watching a crop dusting plane, squashed them both.

She's looking off the other way, looking for prey. I'll chance finding a place to turn around and come back as the other side of the road does have a verge in which to pull off. Off I go. I pass three houses close together. Somewhat unusual out here. Likely relatives who all work this farm. Where is she?

Where did the hawk go?


There she is! She switched trees. I look at her and she looks at me. Perhaps slightly annoyed that I've reappeared to possibly bug her.

Alert, she looks farther up the road. And pointedly watches something.

She rouses. A dusty black car pulls up beside me with an older couple inside. The woman says, "Oh, we thought you were having car trouble."
"No, no, very nice of you to stop and check though. I'm taking pictures of the hawk." I point. The hawk is watching us in a rather relaxed way with interest.
The wife says, " We have a lot of hawks around here. There are Whooping Cranes in the field over yonder." The husband rolls his eyes and says, "Sandhills." I nod.
"Thanks, for the tip. I'll get some pictures of them too."
"Thanks again for checking on me"
As they tootle off, I look back up at the hawk.

No more conversation to eavesdrop on she's decided to head off. Drat!

She heads into the trees just as the black car passes the intercepting road. I'm betting that the hawk is very familiar with those people. They only live 25 yards away. And she seemed far more relaxed about me once they were talking to me. I'm betting that the "lots of Hawks around here" are this female, her mate, and their progeny in the correct season. And she recognizes them in much the same way as Pale Male and Lola recognize those they trust too.

I turn to look at the Sandhill Crane Pair. They are really very far away but the male spots that I'm looking at them immediately.

And in the blink of any eye, the female hunkers down behind the edge of a dip. With only her head visible. I take some photos of the foliage and I notice that there is a flock of small birds flitting around. They go to a wire then flutter to the ground and then right back up to a perch. They are quick. I can't seem to get any under magnification. What are they?

It turns out that they are Bluebirds. A small flock of them. I've always wondered why blue and rufous were good colors to be. Seemed to me that you'd stand out all the time and someone would eat you. But at this season the Bluebirds blend in rather well. And as they are teeny predators perhaps the coloring also helps them sneak up on insects

Even the littlest predator can get "that look" of focus so familiar in Red-tails.


Ah yes, and there is the glare. "You know don't you, that you're disturbing the prey? To say nothing of disturbing me."

What's that?



He fixes on it and flit. The game's afoot!


Then it is back up to the hunting perch. Look how blue his back is in that particular light.

I get the eyeball once again.


Back to hunting.




Ah, Tree Red-tail has returned and is checking me out on the way past.

Tree Red-tail just keeps going. Eventually disappearing beyond the field into the far tree line.
Time to get back in the car to make sure I'm back to where I know where I am before dark.

I pull over to check out something in the hedgerow to my left and when I look to the right, there is Bessie, the Holstein, eyeing me. She does have a very nice set of horns which are perfect for Halloween, don't you think?
Did you ever wonder why in a big herd of Holsteins that there will be one or two Jerseys? For the dairy herd uninitiated, that's the reddish one behind Bessie. Also note that Daisy there has just raised her tail. Do you know what that means? Glad I took the shot when I did. At any rate, the reason for the Jerseys in a Holstein herd. Jersey Cows have milk with a very high butter fat content. It's higher than the Holsteins, which makes for more choice milk. So why not have a whole herd of Jerseys. A few farmers do, but a Jersey doesn't give as much milk as a Holstein, so it's a compromise due to economics.


I'm almost back to Milton, in fact far less than a half mile to the house.


I scan the sky and there is yet another Red-tail, circling across the sky.

Coming my way in fact.

With a lovely glide directly above my head.
I head into the house and open the drape....
Guess who?
