Frequent contributor Mai Stewart has some questions--
Hi Donna --

Saw your posting today. Even tho the Houston St. male RT isn't there, the female must be around -- so wouldn't she be able to provide for H2 & H3 in East River Park?

It just seems to me that they need to be released asap -- even tho they're not bonding to a human, their current situation very different from their real life.

Has H1 been successfully adopted by the Triboro family? I didn't know this was possible -- I thought RTs always defended their territories, including from other RTs. This is very interesting, if it's happening successfully (the adoption, I mean).

And great pix of Thunder, I've loved watching him on the webcam (when he's around).

Best,

Mai

Hi Mai, good to hear from you.
As you can see from the photos, the Triborough Bridge pair are caring for Hous as if he were one of their own.

Fascinatingly, as it turns out, if a Red-tail youngster shows up in a pair's territory and she's near the age of their own, they'll foster her. Whether they know the difference or don't care even if they do, is unknown. Sometimes orphaned eyasses are even added to existing clutches on the nest and all goes well,


That said, we watched closely after the release at the beginning to make sure this wasn't going to be the one exception in anyone's experience in which an eyass wasn't accepted.

As to a female taking care of two fledglings in the absence of the male, I'm supposing that if the tiercel went missing that the mom left with two fledglings on the spot would do her best to raise both fledglings and could be successful barring all the mishaps that befall any fledgling even in the best of circumstances.

I haven't been apprised of the particular details concerning the release of H2 and H3, but I'll ask.

One thing I would be concerned about in this case though, is that no one knows as yet if the infection that downed the tiercel is communicable. If it is, the female may have it as well. Perhaps her body is fighting the infection better but she'd be put at risk of being downed herself with the stress of caring for two fledglings on her own right now. Or it might even be possible that she could infect H2 and H3 with it if she were hunting for them. It would be great to be able to discount that scenario and the cultures should be ready soon that will provide the necessary information to do that or not depending on the results.

But like everyone I'm hoping for what's best for the Houston fledges and I'm hoping that going back to their family will be the action deemed best.



The thirsty Houston Tiercel looks long and fixedly at the water in the river before his trip to the vet.

I received the following from "Concerned Urban Park Ranger" in the comments section. As others who don't read the comments might be thinking some of the same things, I've moved it to the main page for my response, which follows C.U.P.R's comments.


a concerned urban park ranger said...
First, allow me state that I know you had the kindest intentions and were not malicious in any manner. I do not doubt for one second that you are always looking out for the best for any animal in need. With the animal's best interests in mind, I know you will appreciate this advice...



Standard protocol among hawk-watchers should not include handling an animal that you've never handled before in your life. Although you may have been told over the phone how to do it, and it may have seemed simple enough, you could have seriously injured the bird or it could have seriously hurt you, end of story. I know that Adam and Bobby would agree on this. So, while it did turn out well in the end, it was a risk that probably should not have been taken no matter how dire the situation seemed to be at the time. In short, you could have mishandled the bird and injured or killed it.


Another thing to note is that you probably should not be grabbing federally-protected birds and hopping into cabs as park rangers approach you. That may be bordering on illegal activity, I am not exactly sure. If that bird died in your possession you could have theoretically been charged with a federal crime, although the judge would have likely tossed it out immediately since you were acting out of good faith. But, all legalities aside, just please note that we are all on the same side, all concerned about the welfare of animals. I was a bit disheartened to read that part of your story. While there are not many urban park rangers in the city, we have all been trained and handled raptors at one time or another, so please do not hesitate to call 311 and reach out to us. It is a part of our job, we are legally allowed to handle them, so you really should defer to us, Animal Care & Control, or the ASPCA. We all work almost exclusively with the Horvaths, so there should be no concerns.

In closing, as a hawk lover myself, I am happy the rescue went well. Congratulations as I am sure it was quite the adventure! I know it is the dream of many a hawk-watcher to handle one of these amazing creatures in a time of need, but in the future, I think it would be in the best interest of the health and well-being of the hawk to let those trained and experienced handle it. If a hawk is about to be run over by a car, by all means move it off the road, but if it is in a controlled environment and has not moved in some time, there is no harm in keeping an eye on it and calling the appropriate authorities who would arrive there quickly. I know that you did talk with the Horvaths, so perhaps you just did not know you could have reached out to us as well. Consider this a formal introduction! We are here to help and any injured hawk will be taken care of properly. The last thing that I want to happen is for a hawk to be hurt further or die from unnecessarily induced stress.


All warnings and advice aside, thanks again for caring so much about these magnificent creatures. It is hard to imagine where hawks would be without folks like you. With cooperation, we can continue to do our best to ensure a healthy future for any and every raptor. Take care.

Hello A.C.U.P.R,

Thank you for your letter. I see your point that standard protocol for Hawk watchers possibly should not include handling wild creatures, though in the case of a fledgling in the middle of a busy city street who won't allow itself to be herded, it could be a tough call. I suspect it comes down to a personal judgement call on the part of the individual person involved as to their capabilities.

Speaking of which, not all Hawkwatchers are created equal, some have more training than others and that too is part of the picture. I trained for seven years as a field biologist. (Though I rarely mention it as someone tooting their own horn about their advanced education on their blog isn't the least bit attractive to my Midwestern soul.) And though I'd never specifically handled a Red-tailed Hawk, I've handled many other wild animals and birds, including a Great Horned Owl and a Mountain Lion that had been nicked by cars but were still reasonably lively though once again I downplayed that with my little aside on the blog. I've banded birds on government projects. I've rehabbed federally protected birds under the licenses of others as a student in Wisconsin.

Speaking of federal law, after the first time I herded a Red-tail fledgling across a street, thank goodness it allowed itself to be herded, I decided to look into the laws concerning federally protected species so I wouldn't be breaking any of them if one day I had to scoop a fledge out of harms way.

Here's what I found out. Part 1. Any citizen may rescue an animal which is in danger.

The tiercel had already had someone throw a stick, not at it but near it, to check if it could fly. What if it had been hit on that occasion or by someone else doing the same thing. It isn't as if I have the physical capabilities or legal authority to stop someone from doing something like that if they decide to be a jerk about it. Any animal in the city who cannot fend for itself is in danger. Besides the tiercel was sitting in the beating sun on a very hot piece of AstroTurf looking longingly at the water beyond the fence. This bird was dehydrating fast. It was mentally altered and decidedly grounded.

Part 2. According to federal law if a citizen does rescue a wild animal, they have the legal responsibility of taking it to a wildlife rehabilitator or vet within 24 hours.

As everyone would probably agree, a bird's condition and what to do about it often comes down to a judgement call by the people on the spot. And I had plenty of time while giving the bird a chance to recover if this were a transient problem to mentally explore the options. I had no concern that I might injure the hawk as I have confidence and a knowledge of my personal abilities, my shortcomings, and over the last four years, nearly daily observation of the species. I had spoken with Adam about the best way to proceed and he had agreed. Besides if I was a dolt and got footed it's my own fault not the hawks.

As to calling the proper authorities, there are many wonderful well trained educated cooperative Urban Park Rangers and folks who work for Animal Control but for some reason sometimes I don't run across those people when there is a problem.

Some examples: Some years ago when I lived in Brooklyn I came across a wounded Mallard hen in the Botanic Gardens. She was actively seeping blood from her neck due to what looked like a wound received from a dog attack. I looked around and saw no ranger. Eventually one appeared on the other side of the lake. I walked around the lake, carrying my tired three-year-old with me, and told him about the hen. He said, "Yes she's been there since this morning." I asked if anyone had been called or if he was going to do anything for her. He said,"No, it's just a duck." I marched back around the lake, wrapped my jacket around the mallard, tucked her under my arm, grabbed my three-year-old's hand, marched us all to the car, and took the hen to the vet.

Also in Prospect Park, I went looking for a ranger when I saw teenagers throwing branches at the swans. His response? A shrug of the shoulders. I went back and yelled at the projectile throwers. Though small, I can sometimes be scary. They left.

And then there was the time that the ranger I found had been a French major in college, could identify every bird in the park, but I strongly suspected had never touched one. She was perfectly nice but really didn't want to start touching them that day either.

Which brings us to Animal Control. Just like most groups of employees, some are terrific and some aren't. According to the report on the pick up of one of the Houston eyasses, a local resident had called 911 over concern for the fledgling as she was having rocks and sticks thrown at her. Animal Control arrived, threw a catch loop onto the fledgling's neck only and dragged her across the ground. (Which we know is improper use of a catch loop. Even with an animal as sturdy as a raccoon the loop is always supposed to be around the neck and at least one appendage to help prevent injury to the animal being saved. I wouldn't say that a catch loop is ever appropriate around the neck of a young raptor.) The fledgling was then put into a wire cage which isn't appropriate for a bird one hopes to release anytime soon as it tends to ruin the flight feathers.


After Adam rescued Houston 3 out of the street and she was taken away from him by a not terribly polite or informed officer, she was dropped off at Animal Control. Therefore instead of Adam being able to pass her directly off to Bobby when he arrived on the scene so he could look her over immediately, they had to spend time going to look for her at Animal Control. Where she was found in a wire cage.

Keep in mind also that when I wrote the blog about the rescue of the Houston tiercel that it was a story, a piece of writing. Some things are kept in and some incidents get edited out and therefore it isn't the full scenario. Plus emphasis may shift to make it more interesting for the reader.

For instance, the park rangers walking along the fence line. To tell the truth on reflection, they had on khakis but I've no idea if they were rangers or just park workers trying to decide if they needed to herbicide the vegetation along the fence as they were both 50 yards away. I was thirsty, hot, and tired. The tiercel was thirsty, hot, tired, and sick. If the workers had called to me I would have stopped, but as they didn't I went about doing what was best for the bird-- getting him off the ground, out of the sun, and to a place of far less stress. I could have approached the folks in khaki and found out if they were rangers or not but that would have taken time and entailed a lengthy explanation about the bird in the box, standing on hot AstroTurf, in the sun. Then there would have been at least another half hour of the poor tiercel inside the plastic box heating up without care or water while we waited for Animal Control.

As I've said, there are many super rangers and city employees that I've worked with and had great experiences with, but one never knows what the luck of the draw will be and therefore I tend to make a judgement on any given day and situation about what the best way to proceed is for the animal concerned.

In short, it was a judgement call and I feel okay about what I decided to do. Particularly, when I spoke to Bobby Horvath later in the day and he told me I'd saved the tiercel's life.

Urban Red-tailed Hawk Update:The Lead Fledge of 114th St., Hous of Astoria Park, and Thunder of Tulsa.


Photo courtesy of the Horvaths
This is the fledgling suffering from lead poisoning that was taken into the Animal Medical Center on Tuesday, the same day that the Houston tiercel went in for treatment. She currently has a paralysed foot and leg. There is some thought that she may be one of the Cathedral fledglings, daughter of Isolde and Norman.

Can anyone recognize her from her belly band?

And an update from Bobby Horvath courtesy of Cathedral Hawkwatcher, Rob Schmunk, http://bloomingdalevillage.blogspot.com/

The fledgling with lead poisoning is a 7 to 8 week old female found at 309 W 114 St. She has no use of her right toes at this time. There's no way to know if it is temporary or permanent damage. It could be an old nest injury, recent trauma based, or neurological damage from the lead poisoning she has as per the blood results.

Bobby

I spoke with Bobby and he said once they've cured her lead poisoning her leg might come back--but that's a "might". It might not as well.

As for the Houston tiercel, because of his high white count and the fact that it will take several days to grow a culture that will tell us what he is actually suffering from, Mr. Houston is currently on an anti-fungal medication in case he has Frounce, and an anti-bacterial in case he's suffering from a bacterial infection. The medication for the tiercel by itself came with a price tag of $90. I'll find out the particulars but in the meantime give some thought to making a small donation towards our urban Red-tails care.

Eleanor Tauber took this luscious photograph in, of course, Strawberry Fields. The last few days we've had so many examples of what can be done when we work together.
IMAGINE all the things we could do and then go out with a few friends and do them.
("It's easy--All you need is love.")


Speaking of luscious photographs, here are four more from Francois Portmann. First off Hous of Astoria Park aka. Houston 1 is attacked by a Blue Jay. Note it isn't Trib who's getting it, now is it?
A clarification for any confusion, as the Triborough pair had lost their second fledge, a female to internal bleeding from hitting the asphalt below the nest, and as Houston 1 was more than ready to be released, he went to foster with the Triborough nest family when their own eyass Trib, for short, went home.


We had just confirmed to everyone's satisfaction that the Houston pair was intact, within their territory, and making morning visits to East River Park, when the male was found grounded. Thereby putting the plan to release H2 and H3 in East River Park where their parents could find them, and under the watchful eyes of the construction workers who'd been watching their parents hunt squirrels daily, on hold.

Gosh, just which eyass would be laying with his tail in the air in a tree?

Yup, that's Hous again. On the top of the diving board of course. It's hot when laying on metal in the sun, waiting for your breakfast to be served-- better to keep your head in the shade.
AN UPDATE FROM EVER FAITHFUL HAWKWATCHER JULES CORKERY--

Hi All
This morning Atlas came to the middle dining platform around 8 am. He didn't have any food but was still there when I left to get to the train at 8:30. The babies came flying in right after - H1 on the top platform railing and Triborough on a lower side diving platform. They didn't beg and stayed where they landed. Houston pooped and preened. I didn't see Triborough do the same but he was preening and looked comfortable and alert. Still skinnier than H1 but practicing jumping and stretching a lot more.

Today, the lifeguard staff showed up for work so there will be more activity in preparation for tomorrow's opening. The pool opens to the public tomorrow - the pool's sessions are usually from 11 - 2 pm and 4 - 7 pm.
Will let you know what I see tomorrow morning.
Hope all is well with you all.

Jules
(Note: the diving area below the structure the fledglings use for breakfast is not filled with water so there isn't a danger of them falling off it and drowning. D.B.)

Little talons pressed into the bark, Hous looks longingly at something.
Trib is around but he's just much stealthier.

You wouldn't know this hawk was hatched on a TV TOWER or anything, now would you?

Tulsa Hawkwatcher Donna Johnson sent in these captures and an update on the Tulsa Red-tailed Hawk family.

Hello again Donna,
I thought I would send some more pictures of Thunder. Sorry I did not send them sooner. We have had some short visits from Thunder, Kay, and Jay. The local watchers have really had a good time spotting her and relaying details to us about their sightings. They seem to be staying very close to the nest tower.
In the picture of Thunder eating, that's a bird Kay had left in the nest the day before.
Donna J.

Thunder spies something.
Who says day old pigeon isn't tasty!

Urban Hawk Updates: Triborough, St. Johns, New Riverside Pair? Plus the Houston Tiercel


Hous of Astoria Park preens. I love the fact that like most babies with their tender skin, you can see the veins in Hous's eyelids. And because Hous is Hous he goes about preening the way he goes about everything else--with great vigor. Fluff feathers fly.


His attention is caught. He watches something with real focus.
A giant fluff feather blows in. He clamps it in his beak with the longest part coming out the left side of his beak but the wind blows it under his beak...
...and into his right eye. Just his luck.
Ouch! What now? It's not like he can use a talon to get it out.

Then Hous does something I'd never seen a hawk do before. He does a very rapid shake that looks ever so much like the kind done by a wet dog.

It works! And he's back watching squirrels as if nothing had happened. Many things do happen to Hous but he doesn't have time to let any of them bother him. He's an extremely busy bird--so much world, so little time.

A mini-Triborough Update from Astoria Park watcher and educator of the public, Jules Corkery--


This morning Hous was in the trees and Trib was not around. Then at about 8:15 he showed up at the diving or should we say dining platform! Francois showed up in the hopes of seeing breakfast served poolside.
Jules

The Cathedral Report from Hawk Watching Winkie--
Hi Donna,
Quite some story about Mr. Houston. I DO hope that he is doing well. This years is full of twist and turns for ALL! You, too! Your story just shows even more why friendly eyes are SO important. It makes me wonder again what could have possibly become of Tristan. Unfortunately, I was out of NY when he disappeared...not that I could have done much unless I was there at the right time, but I could have tried.
My sightings: Monday one of the juvies was on the Eglise de Notre Dame's roof, about 8PM. It was the slightly larger one, who's belly band looks like a triglyphs. The other juvie's belly band looks like a dart or a delta. I did not see Dart.
Isolde was on a high perch on the scaffolding near the apse and had her eye toward the north. Probably Dart was somewhere close by.Yesterday evening around 7PM, I only found Isolde on the scaffolding. Again almost in the same location as Monday.
Neither of the kids were around, but she was looking down at the other scaffolds and the roofs of the chapels the whole twenty minutes I was there. Lincoln was there later and got some good shots. And Jim, too sighted both of the kids.I think that both red-tail juvies are flying quite well, not just flap hopping.
They seem to wander more along the buildings than in the park. But this year, in addition to the scaffolding around the cathedral there is so much construction going on at the park's new playground and the density of people inside the park is larger, too. I will not be able to make it tonight, but hopefully someone else will see both of the juvies.
Winkie
THE HOUSTON TIERCEL
Today, Wednesday, Bobby Horvath picked up the Houston tiercel from the Animal Medical Center to take him home for rehabilitation. The blood work revealed a high white blood cell count indicative of infection.
No confirmation as yet but Mr. Houston may be suffering from Frounce. A very serious disease that is communicable between Hawks and Pigeons and can lead to death. It is my understanding that it's treated by antibiotics. Mr. Houston, though going for nursing and rehabilitation, is not out of the woods yet by any means.
EVIDENCE OF ANOTHER RED-TAILED HAWK NEST IN MANHATTAN
When I took Mr. Houston over to the Animal Medical Center, there was a certain amount of confusion as coincidentally reception had just had someone else bring in another Red-tail for treatment. I asked where that bird had been picked up but was unable to find out. Bobby Horvath picked up the ball and pursued an answer for us. He left me a message today which said that the second Red-tail of yesterday at the AMC, was a large female Red-tail fledgling picked up at Riverside and 114th St.
This confirms the suspicion that there is indeed another Red-tailed Hawk nest uptown in or near Riverside Park that supports another bonded pair beyond the pair that lost their three eyasses to probable rat poison earlier this season.
This female fledgling is suffering from an injured leg which currently appears paralysed. Her prognosis is not the best but Bobby has taken her into care and will do everything he can to rehabilitate her.
So folks, it's time to go hunting for the mystery pair's nest. If there is one fledgling there may well be more.
And tomorrow, an update from Tulsa Hawk Watcher Donna Johnson, on Thunder the Wonder Red-tail.
