Pale Male's Foot, Charlotte Does Air Conditioning, The Tulsa Hawks, and Red-tailed Hawk vs Rattler


Pale Male on occasion will stretch his foot out, turn his talons in, ting, ting, ting, tingggg, and just sit there. It does give a lovely view of his well turned tarsus but still, it can look, well lets face it-- odd. Particularly when compared with the startlingly taloned view of the other foot.

Red-tails have special rules for behavior while on the nest, and I've seen them walk gingerly by the eyasses with their talons all turned under making them rather look like they've lost their toes somewhere. But no, I'm assuming that they're curled under to avoid any unsightly mishaps with sharp objects and the babies.


And now for something completely different, a pair of demonstrative pigeons snuggle on the edge of the Model Boat Pond. Or the Conservatory Waters if you happen to be looking at your Central Park Map. It's just that they never got around to building the Conservatory and they did get around to sailing model boats there.

Some complete with their own grog barrels.


Remember when poor Charlotte double clutched and then spent the hottest part of the summer roasting on the corbel of the Trump Parc with her young? Well, Brett Odom, the man with the view of the 888 7th Avenue nest site, reports that Charlotte was standing, wings spread, breezin' her body, right in front of the air vents enjoying the air conditioning from the room within. No dumb hawk she.

For awhile this was the mystery eyass in Tulsa. Who was she? Where did she come from? Eventually when things were sorted she turned out to be one of the Langenheim Twins. Whose photos I was going to put up for comparison but the computer seems to have momentarily eaten them. Tomorrow is another day.
THE TULSA HAWKS--How many are there?


The local folks first brought together by watching the KJRH nest atop the TV tower on a CAM have now taken to the field as bona fide Hawkwatchers in the flesh. And they are going to town!

Rose Culbreth, discoverer of the Langenhiem Twins, reports hawk watchers popping out of the woodwork in droves along with experienced and budding wildlife photographers.

Jackie Dover has developed into the Map Mavin, and her maps are extremely helpful with new hawks popping out at nearly the rate of the hawkwatchers. Check them out, they're downright nifty.

Hi, Donna:

We had a busy weekend, as you probably know by now. Here is the latest map update on what we're now calling the South Tulsa Map, with two sightings added (Remington Tower--just off the map a tad; and Manion Park).

We have also added two other sightings in North Tulsa, in the general area of the Tulsa Int'l Airport and Mohawk Park. I'm enclosing a new map of this latter area, as it is not included on the original map (now called South Tulsa).

I'm enclosing a new map of this latter area, as it is not included on the original map (now called South Tulsa). And I'm sending another new map, of all the sightings in the entire Greater Tulsa area. One new sighting is noted on this map--near the Tulsa Fairgrounds. At this time, neither of the other two maps --North Tulsa nor South Tulsa--happens to display that particular area. The Greater map will help you out with that one.

And Tulsa Irregular Sally of Ky posted this marvelous link on the Tulsa Hawk Forum from youtube of a Red-tail nabbing a Rattle Snake. It's rather a stunner. The topic came up because one of the Tulsa watchers reported that snake was served up to the eyasses from one of the nests. (I wonder if they thought "it tasted just like chicken" too?)

Monday Miscellany: Looking at the Little Things--Buster, Chewy, the Energizer Chickadee and More


This is Buster (aka Trib from the Triborough Nest) of Astoria Park. Now that you know who he is what is the next thing you look for having to do with a fledgling? His crop. Yes, he's eaten. Whew. That's a relief. And no matter how many times I've seen a full crop, I'm always delighted to see the next one as I then know no one is going hungry.

This is Chewy the Wisconsin Chipmunk. Wait a minute why does his back have a part down the middle? Because he's wet. It's been raining and unlike squirrels who use their tails as umbrellas, a Chipmunk tail just doesn't do the trick.

Now check his cheeks. For those who haven't seen many Chipmunks, they have internal pouches to stash food. They are short of wearing apparel sporting pockets. They then carry the seeds to their burrow and store it for the long deep snowed in winters of Wisconsin. Speaking of which, just where is Chewy's hole these days? Off I go to investigate. Both Chewy and the backyard shrews prefer burrows under the edges of concrete or asphalt in wet weather.


After scrutinizing all the available hard edges, I come across the entrance to Chewy's burrow. It leads under the driveway. I know it's Chewy's and not the Shrew family's due to size. See Sharpie for comparison.


This is parsley. Just garden variety parsley, which is beginning to blossom. Look closely. There are literally hundreds of beautiful tiny flowers opening up to the sun.

And remember the Energizer fledgling Black-capped Chickadee? Where are his eyes? See them? They're black like his cap. Therefore a predator can't tell where he's looking nor does a contrasting gleam give him away as easily, that he is a creature at all.

But look what happens when he sleeps. His eyelids match the sides of his head so that one does not notice so easily that he is asleep. He could still have his black eyes open and we'd not see them due to his cap.

Ah, and the roadsides are full of the Chicory that's in bloom. Blue flowers are not all that common if you give it some thought. And this, no less a beauty, because the species itself is common.

Remember the post about the squirrels disagreeing as to which of them should have the one dry spot on a tree during the torrential rain storm? And is was coming down in buckets. There was a request to see the photos once I could bring them up. Now keep in mind these aren't beauty shots, these photographs were taken spur of the moment to document the squirrels behavior through a wet window.
The clouds were dark, but then they'd been dark for hours. The air went from no raindrops to bejillion per second in the blink of any eye. With tremendous winds to boot. The two squirrels were both taken unaware, and both taking into account the wind that was blowing sheets of rain, both bombed over to exactly the same tree and the same spot. It turned out to be the only place in the area in which the trunk was dry. There was a squirrel scuffle--

And the squirrel on the left was chased off the dry area and to the side where she was getting somewhat wet. Not as wet as if she were on the opposite side which was being saturated mightily but she's definitely getting wet on her left side.

While the squirrel in the dry spot is hunkering down and thinking about his own business, the squirrel on the left, who's getting wet, is creeping her way up the trunk towards the advantage of --THE HIGH GROUND. The place to be in any battle, just look in any book about military strategy.

She then is able to turn the tables but she doesn't press her advantage. She's willing to share and as she's in the power position, bottom squirrel decides that he won't push the issue either. Both squirrels ride out the storm keeping a close eye on each other. But at least it's a dry eye.

Ever notice how many shades of green there are?

And this is the Mad Monarch. He was flying about FAST! This way and that over the Milkweed patch. Back and forth, up and down. I'm not sure what he was about, but anthropomorphically speaking, he looked to be celebrating something terrific.

How do you tell a Turkey Vulture from a Black Vulture or perhaps even other large species?
The first thing after the wings is a quick look to see if the head is red. It can often still be seen even if they are extremely high in the sky.
What might this one be up to?

He gains altitude through taking several circles each one higher than the previous ones.

And before too terribly long, he's reached the height of the top of the electrical pole.

Where he glides in and makes a rather clever landing for such a heavy bodied bird. If they've just eaten their fill, Turkey Vultures absolutely must have some wind to work with or they will remain grounded until one appears.
I waited and watched for another half hour though virtually nothing seemed to be happening. And that's how I found out that the vultures don't roost on the tower at night but rather sail over to the trees to take their rest.
Keep watching-- even the littlest things.
You never now what you'll find there.

TALKIN' TURKEY, VULTURES THAT IS, AND OTHER PRICKLY SUPJECTS


It's been a year, if not two, since I've checked in on the York, PA, Turkey Vultures. This power tower is on top of a hill. On top of a hill that overlooks a landfill, woods, yards, a major highway and farms. The possibility for a buffet for vultures are nearly endless.


It's late in the day, so one would assume that these fellows have eaten and are now doing the very necessary preening that all birds do. But perhaps even more necessary for vultures as dinner remnants are even more likely to carry "passengers" of various kinds than a more usual dinner for birds.

For whatever reason, an American Crow is on a shorter structure of a different power line and is raising Crow Cain. I am also hearing a Catbird scolding and for a few moments I thought I heard what might have been Red-tail begging, but it was too short lived to track it down in the dense trees and understory in the direction the sound was coming from.


Whatever is going on has attracted the interest of a number of the vultures. I'm not sure if they've a vested interest as in possible "food", or whether it's more like watching a little news or a TV drama before going to sleep for the night.
Here's a juvenile Turkey Vulture who doesn't seem all that interested in the drama concerning the Crow and Catbird and is beginning to get that young bird drowsy look. She of course is not only missing the red head of a mature vulture, but she's also without the yellowish knobbly irregularities of facial skin so common in Turkey Vulture adults.
Ah, the group is watching a truck head up the hill toward the landfill. Perhaps they're wondering as I am what a truck is doing going up there on a Sunday, later in the day? Does someone actually have Sunday garbage pickup in the Little Bible Belt of Pennsylvania or is something being disposed of discretely? Only the vultures know for sure. And perhaps not even them.
Because, after all the looking, one vulture takes off and starts circling toward the land fill. She's doing the lazy circles so common in vulture sky travel...
...but she's definitely heading for the truck and the landfill. (In reality I didn't see the aberration in the wing that seems apparent in the photo. I think it's an aberration in the photography process as opposed to the bird.)
Eventually some 10 or more vultures take off and join a kettle that raises them into the 94 degree heavily humid air and then they drift over towards the dump. The truck is leaving now so they are unlikely to be disturbed at their meal, whatever it turns out to be.
So some of nature's number one clean up crews goes into action, the others preen and as it gets closer to bed time, some drift into the trees in the opposite direction. I'd thought that perhaps they'd roost for the night on the tower, but there seems to be a definite migration towards the woods. Perhaps they lay themselves open to some kind of predator if they remain in the very open struts of the tower. Though I do wonder who eats vultures? Or perhaps it's the thunder storm that is about to blow in. Foliage does give some cover after all from the rain. I suppose one does lay one's self open to lightning strikes as well, up there on that nice metal tower on top of the hill.
It's a rather prickly business being a carrion eater in the modern world. Many humans are so distanced from nature that they aren't familiar with the importance of what these birds do. In fact some people find them not at all attractive with nasty dining habits.
Not a bit of it, they are specially evolved to fill the necessary niche of garbage disposers. Their heads are free of feathers because skin doesn't catch and keep as much bacteria as feathers are likely to do.
They're rather heavy clunky fliers but it isn't as if they've got to out fly their lunches, now do they? What those big clunky wings do give them though is plenty of surface area to mantle with. Thus preserving their personal portion of the food.
The list does go on as these birds are quite specialized to succeed in the world of left overs. I was thinking a good bit about specialization today.


The Thistle has developed rather substantial prickers to protect it's seeds so that they're still there on the seed head and ready to float high on the wind come maturation time. Though they don't protect them all, for small birds do find ways of harvesting them for food.


No these aren't our indigenous raspberries. These are an exotic called Wineberries though I would assume closely related to our raspberries. Note the stems. Every possible place on a stem for a sticker, has one. Now berries are supposed to be an evolutionary advantage because mobile creatures eat them and disperse the seeds to a larger area. So why all the stem defense? Is it possibly to protect the canes, which produce berries for a number of years before giving way to new growth? The berries don't have prickers.

Now in some species of raspberry type berries, in Wineberries in particular, the very ripe fruit commonly falls off the stem and tends to break into individual fruit enclosed seeds. Whereas in Red Raspberries the over ripe fruit often stays on the stems and dries. Are these berries specific to particular eaters? And as the Wineberries evolved in a different ecosystem entirely are their berries particular to an eater that isn't even in this ecosystem? Possibly, but there seem to be more than enough dispersers of their seeds to allow them to thrive without cultivation.

As you yourselves know, for the curious-- there are so many questions and so little time.
