Puzzled Does anybody know what happened to this cam? I used to watch this nest and forgot all about it. One minute there were 3 chicks and the next there is no cam and no pictures either! Oh My

cam is still down....and her is an update about one nestling that died.

May 9, 2010 Update: Follow-up on nestling death

by Bob Sallinger

Posted on May 9, 2010 at 9:50 AM

For some reason the Raptor Cam feed seems to be down this morning---not sure why that is--I have a call into KGW (9:00 am)

Not surprisingly the death of one of the nestlings has drawn some strong responses. I appreciate everybody's passion for these critters. If you are upset, consider going out and doing something good for the birds in your neighborhood on this sunny Sunday---plant a tree, hang a bird feeder, Audubon has great ideas for how to get started. There are birds all around your neighborhood that are going through a process that is every bit as exciting and challenging as the Raptor Cam Red-tails.

Viewers have raised a number of issues and questions that I will take my best shot a addressing:

1) How do you know it was Trichomoniasis? We don't actually know what caused the nestlings death. I suggested that it might potentially be Trichomoniasis because the way he was holding his mouth open was consistant with what we sometimes see with Trichomoniasis infections. However we also see birds do this for a variety of other reasons as well including injuries, developmental problems, respiratory problems and other types of oral infections. Or it could have been something completely unrelated to the mouth. Without a necropsy (bird autopsy) we will probably never know.

2) If it was Trichomoniasis, won't the other siblings now become infected? If it was Trich, then the other siblings have already been exposed. Given how common Trich is in pigeons and how much of the red-tails diet is composed of pigeons, they have almost certainly already been exposed many times over. Most birds simply fight it off and build-up immunity. We find that birds that develop serious infections usually already had some sort of significant problems at the time they we exposed that suppressed their immune system and allowed the Trich to get a foothold. If the other siblings are healthy, then their risk level really has not changed...and again we don't know that it even was Trich.

3) How is this case different from other situations where Audubon "rescues" birds? There is no perfect clear, bright line that makes right or wrong to assist a wild animal. The rule of thumb however is that we tend to be more likely to interfere in situations where human action directly threatens or injures an animal (for example animals that have been hit by cars, shot, oiled...) and less likely to interfere in situations where injury is the result of natural processes (for example a Cooper's Hawk preying on a Western Tanager, Weather related impacts, nestling competition...) Nestling mortality in most cases is at the far end of that continuum---We know going in that not all nestlings are supposed to survive under natural circumstances. Many birds have large clutches as a survival strategy to compensate for high natural mortality rates during the first year. If a pair of Red-tails has 1-4 young for 10 years and they all survived, they could potentially replace themselves 5-20 times over! Under those circumstances other factors (competition, disease, ect) would eventually bring the populations down.

4) Shouldn't we have at least tried? There will always be different opinions on these types of things---that is fine. However, I think that there is a certain amount of hubris in assuming that we as humans are better equipped than the parents to take care of these types of situations. The relationship between the parent and the chick is the product of millions of years of evolution. Are our incubators, antibiotics and feeding tubes necessarily superior to that warmth, natural immunity and care that the parents are able to provide? Most people who have worked with wild animals will tell you that humans are a very poor substitute for the natural care that a wild parent can provide for its offspring.

5) Does this sort of thing drive-up ratings? It is always good to have a cynic in the audience--they keep you honest. I suspect that if the goal was "high ratings" the thing to do would have been to stage an elaborate rescue and then milk it for everything it was worth.There are plenty of shows on TV and Cable if you want to watch that sort of thing. In my first blog this year, I promised viewers an "unfiltered" view of the birds as they go through their nesting process---that will undoubtedly include aspects that are inspirational and amazing but also things that will make you sad. I can promise that it will always be interesting and real but I cannot guarantee a happy ending. For the record, Audubon does not make anything off of Raptor Cam. I can't speak for KGW and how their advertising works, but I would note that you don't typically find Fortune 500 Companies advertising on the Raptor Cam Page---throughout this season KGW has been using the page for advertisements for the United Way and Tips for Green Living.

6) Does this mean Audubon would never rescue the Red-tails? No. We make decisions based on the circumstances using the the type of criteria that I described above. In prior years we have treated Raptor Cam offspring that have slammed into windows and been hit by cars.

Tomorrow we will get back to tracking the development of the remaining two nestlings.

Enjoy the sunshine!

Bob

The nest had a problem in 2008:

Out Two Will Fledge and One Will Be Left Behind June 1, 2008

The male hawklet is not doing well. He seems to have problems with his beak and his eyes. The lower part of his beak (the lower mandible) is over-grown and juts out beyond the upper part of his beak (upper mandible.) This keeps him from being able to close his beak and makes it very difficult for him to rip and tear his own food.

As a result, he begs almost continuously for food and his parents are still feeding him. Even being fed is difficult for him, with his malformed beak. Mom is very patient with him attempting over and over to put food into his mouth and cleaning his beak for him where food remnants are building-up. She is a good mom!

His eyes appear somewhat cloudy, swollen and crusty, perhaps from some sort of infection. Infections and parasites can cause developmental problems.

At the end of the video, you can see a parent arrive to check on the hawklets.

"We are going to let the two healthy birds fledge without any disruption. If possible, we will grab the third nestling once his siblings are airborne. We will give him an exam and see if there is anything that can be done to fix his ailments. If it is something that is quick and easy, we will put him back out on the ledge to rejoin his family. They will all remain in the area for many weeks following fledging so we would have at least a little time to treat him and still be able to put him back out. If it is something more complicated, we will have to explore other options."

I very much doubt that "quick and easy" will work. Parasitic infections can be treated, but it may be too late to undo the damage. The "other option" is probably humane euthanization.


People who watch wildlife cams must accept the reality that many of the birds will not survive. Many believe wildlife have a carefree life, but now we know better. If all survived, there would not be enough food or habitats for them.

Video: Only Two Redtail Chicks Remain at the Portland Nest

The remaining two nestlings look healthy so far.

6:04 p.m. EDT (I don't know for sure what time that is in Portland) Parent brought what appears to be a grey/white pigeon to nest, both eyases jumped up to parent. Parent de-feathered prey, began to feed eyases, who jumped at parent eagerly to take bites from beak. Both alternatively on haunches or feet, though one seems to stand and walk a bit better than the other. 6:25 p.m. feeding slowing down somewhat. Parent still in nest with prey. All looking around. I will try to post scap later. I am new to hancock.

The cam is up and running. Haven't seen a Retail yet, but they have obviously been working on the nest.

This screenshot was taken about 4:05 PM local time.
