Wild NYC, More on Do Redtails Grab Dogs from John Blakeman, and Hawkwatching Bill at Police Plaza Passes Along a Hawk Sighting


Here are a couple more photos from The Wild NYC Symposium. Here's Abby from the Tenafly Nature Center talking about and holding a Red-tailed Hawk. Also let me point out, the wonderful woman who pulled the whole symposium together to the delight of so many, Myisha Priest, sitting on this end of the sofa wearing the white earrings. It was a very special event for all involved.

And here is the discussion involving owls, with a Barred Owl on the fist. There really is something about a raptor, as the room was packed, outside the windows was packed with a changing parade of excited viewers, and there was no one who saw the birds who didn't have a little catch in their breath, or at least a small quickening of their heart when they laid eyes on the raptor visitors.

Unfortunately I don't have any photographs taken inside the theatre during the speaker's talks and the lively discussion that followed. I was one of the speakers on the stage. Somehow I thought that me sitting up there popping off flash photos would be more than a little distracting.

Speakers included myself
, Meredith Comi of The NY/NJ Baykeepers, and Leslie Day author of "Field Guide to the Natural World of New York City".

Did you know that one single mature oyster purifies 50 GALLONS of water a day? I didn't either. Boy, do we need more oysters in the world and that's what the Baykeepers are up to.

NEXT UP--MORE DEBUNKING OF THE URBAN LEGEND THAT RED-TAILS GRAB DOGS AND CARRY THEM AWAY ,

The other day, I heard a women say that neighbors in her area have problems with Red-tails grabbing their dogs and carrying them away. Also that Red-tails, even those in captivity, don't know one person from another.

Donna,

The lady, shall I say judiciously, is in error. (Well, she's ignorant on the matter.)

No, red-tails NEVER attack pet dogs of any kind, from the smallest little pooch breed on up to the largest wolf-like types. They certainly don't fly off with them, even if they come across a dead one. All dogs are too heavy.

Red-tails are just plainly too smart to attack such an animal.

And yes, my red-tail sure knows people. All falconers know this with their birds.

Interestingly, a red-tail, if it wanted to, could attack a small dog and kill it. But they just don't do this, at least in urban areas with human pets.

But here in northern Ohio, one of my apprentice falconers (now a master falconer) watched a wild haggard formel drop down onto a sleeping gray fox, sinking its talons through the eye sockets and killing the animal. It did this after studying the sleeping animal for some time, calculating how to quickly dispatch the fox.

John,

Thank you.. Which of course leads to more questions. :-)

Did the Red-tail eat the fox?
Or was it a dispatching of competition kill?
Or perhaps are they wired, when opportunity presents itself, to kill predators that would kill fledglings?
Or do we know at all?

Best,
Donna

Donna,

The haggard's kill of the sleeping fox was an atypical aberration, for sure. The bird spent a good time surmising the sleeping fox and calculating just how it could easily dispatch the mammal.

But exactly why it undertook this excursion into severe confrontation, albeit on the hawk's, not the fox's terms, is unknown. I don't think that protection of young or anything of the sort was a motivation. I do know this. Red-tails are drawn to fur of any kind, for which they have a strong experiential attachment to the flesh beneath. I would imagine that the sitting haggard saw the lush fur of the sleeping fox and that prompted a killing calculation. The bird may well have killed other smaller mammals it caught sleeping or resting.

We falconers (who see this more closely than anyone) know that experienced red-tails know to kill by sinking talons into the crania of their larger prey, often through the eye sockets. This old hawk would have been expert in the matter.

We don't know if the bird ever came back and fed upon the carcass. It may well have.

Sincerely,

John A. Blakeman

Thanks John. Very perceptive. We do know that experienced Red-tails are quite willing to bide their time for the right moment.

Speaking of the Red-tail and the fox, one thing just occurred to me which hadn't previously. As we know that Red-tails can tell individual people apart given opportunity, perhaps they can tell other individual animals apart as well. Perhaps the hawk had something personal against that particular fox? Maybe it isn't as crazy as it sounds.

A while back on the blog, some of you may remember, I was called by a friend about a Red-tailed Hawk feeding on a fresh road-killed skunk. I wasn't far away and made it to the spot in a few minutes. The Red-tailed Hawk, not being able to take the heavy skunk into a tree, had been flushed by a fox who proceeded to pick up the skunk, run across the road with it, and disappear into the woods.

Fox are opportunistic and I wonder if it's possible that a particular fox might make a habit, given opportunity, of boosting the prey of the raptors in her territory. Which might cause an experienced very bright individual hawk to make an opportunistic attack on that particular sleeping fox.


From Bill down at 1 Police Plaza who sent in a Red-tail sighting a while back--

Haven’t written to you in some time as I have yet to spot another hawk down here at 1 Police Plaza.

However my buddy just took these photo’s on Ovington Avenue in Bayridge, Brooklyn. Thought you might like them. Evidently the pigeon got away!


Thanks Bill. Your buddy caught a moment that doesn't happen very often and he was ready with his camera besides. Those are great reflexes!

If you look at the photo above it appears as if the pigeon is actually banking toward the Red-tailed Hawk who is perched on the chain link fence.


Did the pigeon fly right into him? Did the wing go out to bar a get away? However it was managed the hawk may have one foot on the pigeon, who no doubt, is attempting to get away.

Presto, chango whatever the technique was on the pigeon's part, it worked, and she's on her way-- though having gotten a little rumpled in the feather department during the process.

Wild NYC Symposium 11/18, Chris Crow Rehydrates Supper, Isolde and Norman Return, Janesville Bald Eagles, and Sally Does TV


Chris the male Crow grabs some pineapple covered in rather dry rice off the goodie stump.


He then flies over to the bird bath and places it in the water to rehydrate. (I love it when Crows "cook"!)

That is the beginning of a long sequence of action, but there is lots of news so instead of waiting another day to put up the news in order to get the whole sequence of photos up tonight, above is the intro to the beginning so you can get the gist. Then we'll do news and you can continue on down for the end. Think of it as a Neil Gaiman novel because most of the beginning will be posted in another blog.

Sometimes stuff happens, the best laid plans...

NOW TO THE NEWS--

First up, a Symposium--WILD NYC, 11/ 18, that's this coming Thursday, for those within reach of the City, from 3:30 to 6:00pm, in the Gallatin's main event space on the first floor of 1 Washington Place, corner of B'way and Washington Place between Waverly and 4th.

Participants who will speak and take part in a panel discussion plus a Q& A with the audience include Linda Couturier, author of The Hopes of Snakes, Meredith Comi who is the director of the NY/NJ Baykeeper's Oyster Restoration Program, yours truly talking about our love affair with Red-tailed hawks, and Chris Nadereski, (who works with Peregrine Falcons and other raptors), will be bringing his birds with him.

NEXT--Word in from Nara M., who's living room abutts a favorite roost fire escape of Isolde and Norman of Morningside Park and the St. John the Divine Nest--

Hi Donna,
Tonight they're back, with a slightly different sleeping arrangement: one is on the railing, like last night, and the other is perched on top of the a.c. unit in the next window over! (it's mounted on the top of the window, so we can just see some tail feathers hanging down). I just went to check what was going on as there's a clacking sound coming from the a.c.--not sure if it's the bird's claws or if the a.c. unit is settling under the weight.

And in from Robin of Illinois, a link to watch long time contributor to the blog, Sally of Kentucky, who does work with Raptor Rehabilitation of Kentucky on a KNET TV news magazine. Sally is in the last news segment of the program.

And from Janesville Eagle Watcher, Beakerless-- just saw the pair of bald eagles at the Racine Street bridge in Janesville. Both were fully mature and one was significantly larger than the other. They were again flying low over the river looking for fish. I haven't seen them through the summer months and was overjoyed to see them back again.

Now to the beginning of the end of Chris Crow, his mate, Carol and their yearling, Junior, who rather hilariously is the spitting image of Chris only he isn't yet full grown.

At 4:28:28, (all times PM) Carol and Junior show up at the bird bath while Chris is over on the goodie stump selecting more pineapple segments. And here we have an excellent photo to go over some of the ways to tell a female crow from a male crow. Junior is on the left and Carol on the right. Compare their beaks.

Even though Junior is still smaller than Carol, for the moment at least, his beak is definitely longer and chunkier than hers.


Also compare the tarsi. Junior appears far more long legged (just like Chris) than does Carol. And it isn't just because Carol appears to be pleasantly plump. (Hey, that Chris really knows how to rehydrate some tasty meals. )

Males also have longer tails though this isn't a good photo for that comparison.


Speaking of Carol and food, she leans down and selects a tidbit that Chris put in the bath earlier.
4:28:40
Chris is over on the stump selecting out more pineapple while Carol and Junior pause for a drink of water.
4:28:48
Crows, who like most birds, are not capable of the sucking action of pigeons and doves, fill their beaks with water and then lean their heads back so it runs down their throats.
4:28:48

Chris continues to go about his business even though he knows I'm there, though in the house a good distance away and behind glass, but Junior and Carol, having heard the camera, are now giving me the crow eyeball.

They don't relent.
4:28:51
4:28:56
4:28:57
Finally Junior takes off and Carol isn't far behind.
4:29:00
Chris carefully watches where they are going.
4:29:04

Still watching.
4:29:05
He makes sure I haven't crossed any boundaries while he was otherwise occupied.
4:29:14

He caws four times, with a little something in his mouth.

4:29:15

Eyeballs me.
4:29:18
And goes back to picking.
4:29:32

Yup I'm still there.
4:29:33

For whatever reason he seems to stare at the bits for several seconds before picking any of them up.
4:29:35
4:29:37

Gulp, and it's nearly gone.
4:29:38

He stares at the pile of food.
4:29:40

Stares some more.
4:29:43
Still staring.
4:29:45

Then picks up a pineapple segment.
4:29:48

4:29:56


4:29:59
A little hard to get down perhaps?

4:30:02 Choosing.


4:30:05 Big bite.

One of the other crows does a fly-by.

4:30:19 And Chris heads for the bird bath with his big bite and puts it in the water.

4:30:22 Tending.

4:30:24 Watching the progress.


4:30:26 He pulls it out and tests it.

4:30:27
Might just be alright.
4:30:28

Is he looking for Carol and Junior?

4:30:41 Back in it goes.
4:30:42 He stares for some seconds.


4:30:47

4:30:48

4:30:50

4:30:51 And he's off.

4:38

5:05 And a snack for later.
