The Piggley Wiggley Red-tails and Jane and Rock Bald Eagle


It all started in the Piggley Wiggley parking lot.
For those not familiar with Piggley Wiggleys, they're a chain of grocery stores. I'd gone in, gotten some groceries, including some frozen items, when my cell rang as I was crawling into the car and I began having a heated discussion.
Suddenly a Red-tail winged through the parking lot heading west. I thought, "Hmmm, where is he going?", while massaging my neck from the whiplash of jerking around to see whether that really was a Red-tailed Hawk. My discussion had degraded by then into the fact I should be heading west on Park View Drive for some shots of the foliage.

West? Hmmm, that's the direction the Red-tail went. It's quite cool outside-- the groceries can live through a few minutes before being put away, right?

I head west.


Scanning the treeline far, far across a very large field, I spy them. And it's a pair! Why are they here in particular?


Then I realize there is a combine clearing the corn field on my side. RODENTS! As a field gets cleared eventually the rodents get spooked and make a break for it and that is where the Red-tails come in.

The male takes off.

Landing in a nearly naked tree a couple of trees over from his mate, north, and looks fixedly into the far field.
About then a station wagon pulls up beside me. A voice says, "What are you looking at?" I turn around and there is a very large friendly man sitting in said station wagon. It turns out that he's a painter. The kind that does bridges, and all sorts of outdoorsy kinds of things that raptors hang out on. He begins to tell me about the falcons in Milwaukee and that leads to the pair of Eagles that nest in Janesville, the next town to the south.
"WHAT?", I squeak, there was an eagle's nest just a few miles away and I missed the whole thing? "Where?"
Then, John and I, we're on a first name basis by then, begin the dance of---"Well just go down to such and such Lumber Yard..."
"Wait, wait, I'm from out of town..." To make a long story short, he volunteers to take me to where the eagles hang out in Janesville by the Rock River, right that minute. (Now there's a real temptation, but I've got all those perishables in the car...)
John turns out to be a very nice man, all 6 feet 9inches of him--he'll wait while I go home and throw the groceries into the fridge and freezer and then he'll show me the way.
I do it and we're off!

And there they are just like he said they'd be. That's Jane on the bottom, named for the town of Janesville and Rock, as it is the Rock River they nest by, on the top.


About then, John, he's the human, remember, gets a call from a friend with car trouble and has to go. But he also says he knows where some Screech Owls roost, I should call him, and then he's gone.
Wow, John is turning into the gold mine of Wisconsin raptor finding help.
By this time Rock has headed out to his usual evening roost tree but I stick with Jane.
Jane is looking down rather fixedly at a group of Geese that are swimming by. I wonder if an Eagle can take on Canada Geese? Most likely as they've been known to go for swans in the air anyway.



Jane then stares at me. Thank goodness, finally some human habituated birds, bless 'em. She at least doesn't mind the scope. Whether Rock minded or not I'm not sure as John says he often goes to the other tree about this time in the evening.


And that's when I realize I can't read an Eagle's face. My face experience with Red-tails doesn't cross over at all, at least not yet, with an Eagle's face. I'd have been able to tell whether it was the scope or just time to move perches were it a Red-tail. Drat.

I then have another thought. To me, an Eagle's face always seems to be expressing fierceness, with a good helping of grumpy thrown in. I'm going to have to work on it.
I realize it is beginning to get dark and this is a rather deserted section of town down here by the lumber yard.
I then see this "thing" at the base of Jane's tree. What it that?

Well? What do you think it is? It's hard to judge the size from across the river, but somehow it seems to be almost human sized. A giant stuffed seal who wears a hat? A bizarro disguise for duck hunting?
Jane is giving me the eye in a way that tells me she's about had enough of me. Or is that just the "grumpy" I see in Eagle faces. At any rate, it is time for me to head out. I'll definitely be making some more visits to the eagles before they take off for the winter. Maybe I'll even be able to see "cheerful" in their faces before they leave.
This is where I had placed the photos for Cheryl Cavert's of Tulsa's update for this evening. Blogger ate them. Not that blogger has eaten he's now become tired... so more from Cheryl in the next post.

Kay and Jay Red-tail's Neighbors and Do Ravens Kill Pigeons-A comment


Photograph by Cheryl Cavert

What a beautiful fledgling sitting at his ease, with one foot tucked. Up first today, another installment of Cheryl Cavert's Red-tail Round up from Tulsa--

Donegal,

It seems Kay and Jay's RT hawk neighbors all had more successful nests then they did this spring. Immediately to their east, the 36th&Lewis pair had two fledglings, as well as RanchAcres and Langenheim. The 51st&Peoria pair to the south had one juvie.
I've attached a few photos of one of the RanchAcres juvies.


One evening while trying to eat its share of a rabbit (the back half), a mockingbird harassed it almost nonstop for 20 minutes. One photo shows how close the mockingbird was getting!!!
Next - tales of the Langenheim juvie!

And here we have it. A juvenile Red-tail looking Cheryl straight in the eye. Or straight into her eye through the camera, likely. I suspect it looks odd to them because they'll look at it for quite some time.

How close is that Mockingbird getting? There is definite contact being made. Enough in fact for the Mocker to scrunch the young hawk's feathers with his feet. Some of the species of the common smaller attack birds, such as Mockingbirds and Catbirds, seem to know a juvenile hawk from a more experienced mature one and take advantage of the information.

The juvenile takes to eating again. On this pass over it looks almost as if the Mockingbird is checking out what the hawk is eating--just in case.

Next--A contribution from Thunder, an Ontario observer, to the discussion surrounding,
Is Samantha Raven Actually Killing Pigeons?
I'm in northern Ontario. Well, last Friday, October 23rd, I witnessed a raven kill a pigeon. I work in a building, and as I was leaving for my lunch, a pigeon was feasting on little bits on the ground. A raven about 2 1/2 feet tall dive bombed directly into that pigeon and drove its beak clean into it. Poor little fellow never saw it coming. The Raven then decided to eat it, freaking out kids passing by.


Hi Thunder,

Thank you for sending in your observation. The plot thickens.


I’ve got some questions I was hoping you could help me with. You very well may not know many of the details I’m asking after as I realize you were attempting to get some lunch yourself, but any details you remember would be great.

Did you happen to see where exactly on the pigeon the predators beak entered for the kill strike?

Was it a clean kill, as in the pigeon died immediately or close to it?

Was the pigeon foraging on a sidewalk?

How busy was the area when the strike was made when it comes to people and or vehicles?

Did you see the Raven leave? Was she finished eating or did she flush off due to a disturbance and if so, did she take the pigeon with her?

Thank you!

RED-TAILED HAWK UPDATE: Tulsa Hawks-Kay and Jay, Plus Hawk Hill and Citizen Science

An update on the Tulsa KJRH TV Hawks, Kay (left)and Jay (right) from Tulsa Hawkwatcher Cheryl Cavert --

Hi Donegal,
I recently read where you were asking about an update on the Tulsa hawks. I have been meaning to send some photos on to you all summer - but with your summer activities and blogger problems, and my summer activities and computer problems, time has gotten away from me.


I regularly see Kay and/or Jay perched on the KJRH nesting tower. Late in the summer evenings, they were often perched together on the goldenrod (sticks out to the east, just slightly below nest level). I've attached a couple of photos from an evening in August.


Photograph by Cheryl Cavert
- the lighting is not very helpful picking up fine details - but the second photo shows how well balanced Jay is as he stretches - never even wobbled!


Photograph by Cheryl Cavert
Kay was perched on the goldenrod on October 16th on a beautiful sunny afternoon - not something we have had much of lately in Tulsa. Later that evening, I spotted her on a lower perch on the tower, Jay flew by and she flew off after him. I saw Kay again this evening, sitting on a pole next to the KJRH hawk cam, helping the hawk cam watch the evening traffic.
I will send on additional updates of Kay and Jay's neighbors. I have had some delightful hawk encounters this summer - especially with some of the juveniles!


All my best -
Cheryl (aka catgirl of the Tulsa KJRH hawk forum)

It's grand to hear how Kay and Jay are doing. Thank you, Cheryl.

AND FROM ROBIN OF ILLINOIS FOR ALL YOU HAWKWATCHING CITIZEN SCIENTISTS OUT THERE--
http://www.dailykos.com/story/2009/10/25/793980/-Dawn-Chorus-Birdblog:-Citizen-Science-Rules!-

"GGRO and Citizen Science: Beautiful diary. I can imagine how much patience it took to get these amazing photos. By coincidence, I recently visited my daughter in San Francisco, and got to accompany her and her boyfriend Walter Kitundu hiking in the Marin Headlands and visiting Hawk Hill, where Walter volunteers as a bander.

The day we visited, the weather was perfect, and the view was spectacular, but the day before, Walter had spent a miserable day huddled in the blind in the fog without any birds. ( Walter's blog isBird Light Wind on Linaetus blogroll, and has Walter's bird photographs. )


GGRO is doing important work, tracking and documenting these beautiful birds, and educating the public about raptors. Here in Texas, since I retired as a public school science teacher, until I discovered citizen science, I missed the field studies I used to do with my students. Citizen science has provided a way to stay connected and make a contribution to science.

Project Feeder Watch last winter had us watching goldfinches. I also monitor rainfall with our backyard rain gauge for the Community Cooperative Rain and Hail Study, and get to see my data posted on the daily on-line map, and linked on the NOAA website.

I just discovered the National Phenology Network, which monitors seasonal changes in indicator plant species- one way to study the effects of climate change. I highly recommend these and other citizen science projects, especially for teachers who are looking for ways to get students involved in the exciting process of doing real science."
