Fly Larvae Infestation in Young Red-tailed Hawks' Ears = Veterinary Intervention @ the
Вставка
- Опубліковано 17 тра 2024
- After keen-eyed volunteers noticed an odd movement in the ear of M1 on June 8, veterinarians from the Janet L. Swanson Wildlife Hospital examined the footage and identified the cause as fly larvae in the ear. They noted swelling and that the chick was keeping its third eyelid over its eye, which is a sign of pain. If left untreated, the infection was expected to worsen. M2 also appeared to be exhibiting the same condition. We worked as quickly as possible to arrange a lift to enable a veterinarian to perform an examination of the nestlings and treatment as needed. The exam took place on Sunday, June 11.
That day, Dr. Rolfe Radcliffe from Cornell University’s College of Veterinary Medicine went up in a lift to the nest site with staff from Bird Cams and Cornell Facilities. A brief inspection confirmed that all three young had larvae in their ears.
The young were brought to the Wildlife Hospital where veterinarians noted mild tissue damage and inflammation. Veterinarians removed nearly 50 larvae, cleaned the young hawks’ ears, and provided the young hawks with fluids, antibiotics, and antiparasitic medication. Because the young were still in good health other than mild tissue damage, the prognosis is good.
Big Red, waiting on a nearby building, dove at the team while they returned the nestlings, a behavior that birds use in response to predators at their nest. She then perched on a nearby light tower to oversee the return of the chicks to the nest, and was soon joined by Arthur. Soon after the team descended from the nest, Big Red returned and began feeding the nestlings a chipmunk that Arthur had delivered while they had been away.
The Bird Cams team would like to give a heartfelt thanks to Dr. Radcliffe and Dr. Sara Childs-Sanford at the Janet L. Swanson Wildlife Hospital for their guidance and expert care. The keen observations of hawk cam volunteers “babynurse1” and “keys” raised awareness of the nestlings’ situation, and they were instrumental in collecting valuable video footage of the infestations during late-night cam operations. As always, Rich Barrows, Brian Becker, and Cornell Facilities were excellent partners in efficiently and skillfully getting us to and from the nest. Finally, thanks to the cams community for sharing their observations as well, and to the cam volunteer corps for providing great feedback and engagement with the community during and after the intervention.

A Red-tailed Hawk pair has been nesting above Cornell University’s athletic fields since 2012. They have made use of two different light towers for their nest sites. In 2012, 2015, and 2018-2021 they used a tower near Fernow Hall, and in 2013, 2014, and 2016, they used the tower nearest Weill Hall. We installed cameras at both of these sites to get a better look at the intimate behavior of these well-known birds as they raise their young amid the bustle of a busy campus.

So glad it was caught early! Thanks to viewer & cams 🎉 🥰 Thanks for having us & all you do @Cornell
Hawks Rock! I wish I could raise them without all the BS legal hoops.
Thank you to those that realized the young hawks had ear maggots and the vet and all who assisted helping the young hawks. 🙂
Wow, I am very thankful to the person
who noticed the issue and the medical team, support team. I am also thankful that Big Red didn't hurt anyone
Blessings to all!
Well done, everyone. I've used Capstar to remove fly larvae in Crows and GHO as well as opossums.
I understand why you're hesitant to "let nature take it's course" on these wild kids...but as a rehabber who understands the power of social media as well as the love of hawks, I get why you opted to intervene. I'm so glad you did.
hi leslie ~ why or how would these bebes get maggots in their ears ?
@@colecolettecole I was wondering that too. I don't see any explanation here.
@@colecolettecole flies are drawn to leftover prey, such as squirrel parts, chipmunk parts (even tiny ones). Those flies lay eggs on the leftovers, which hatch into maggots. Maggots look for dark/damp environments to survive. The inside of a bird's ears or nares (nostrils) is a perfect environment for them to thrive in.
Maggots do it because they can. Old long-haired dogs that are outside a lot are also at risk. Keep their behinds trimmed and clean, especially at this time of year.
@@snlself Since birds are carefull to poop to the outside of the nest from a young age, you would think that the parents would be more hygienic in cleaning out the leftover carcasses, and why not eat the fly larvae also? Grubs and worms are a staple of many species. Would wild birds have been able to kill the larvae with these insecticidal greens? So much to learn….
Can you imagine arthur - Damn kids - i brought dinner and damn if they're gone!
Plus “and they didn’t invite me!”
These beautiful and amazing birds have real-life guardian angels. Thanks to our Cornell Hawks community, the vets, and the very brave people who went up to the nest to retrieve and return the chicks. What a joy!!
Thank you to all involved for all you do for our beloved hawk family and for sharing this video with us. 🪶❤❤❤
Indeed! 🙏👏💚🩵
Thanks to the Viewers, Vets and Crew! Great Job! ❤
Thank you to everyone who helped these three! So glad to hear that they're going to be alright.
Wow, amazing video. We’ve all been waiting for this one.
IMMENSE GRATITUDE to the hawk-eyed babynurse1 and keys, and every other person involved from the ground crew, to the vets, to the bogs. These are some very lucky little big birdies.
A huge Thank you to all involved in examining and treating these precious young Red Tailed Hawks! Big Red and Arthur are such good parents! I liked Dr Radcliffe's thouhts on what Big Red and Arthur were thinking. Thank you for all that you do for these majestic Red Tailed Hawks! 🌷💞
I do applaud the person who knew that there was something wrong with the Hawklets and felt that the Vet team needed to come and help. MAN!! I’m so very pleased it’s the team for going to the nest and helping out the Hawklets and it looked like mom and dad knew that the babies were being helped and the concern I had was that the two adult Hawks wouldn’t come back to the nest after the Vet team was there but I think the adult Hawks knew the Hawklets were getting help.❤️🙏👏🏻👏🏻. You humans are super awesome and very much appreciated.🙏👏🏻👏🏻👏🏻. There aren’t too manyEagles nest people go to the nest to help babies Eaglets when it is needed except for SWFL Eagles. Now these Hawklets have a definite fighting chance to live and fledge when it’s time. God bless you all so much and the person who saw the problem too. You all have my utmost respect. Hugs love and blessings to you humans and to this Hawk family too. Sue M. (Clearwater, Florida)👏🏻👏🏻👏🏻🙏❤️🥰👍🏻👍🏻🌟🫶🏻❌⭕️❌⭕️
Imagine the wonderful tales these young hawks will have to tell about the time they were abducted by aliens...
Many thanks to everyone for the excellent observance, quick action, and superb video!
Thanks for taking care of these beautiful birds. Love being able to watch them on the cam. Thank you all who make this possible
🥰
Thank you, thank you, thank you, Thank you, thank you, thank you, Thank you, thank you, thank you, Thank you, thank you, thank you, ❤❤❤
Thank you so much for this intervention as in past years there have been cases where a lack of intervention ended sadly, but the fantastic coordination amongst all involved, the speed with which the vets worked on the chicks and the great footage by Cornell and Karel are very much appreciated.
Thank you so much yet again. I'm sure the chicks are saying thank you too!
Y’all are amazing. Just amazing !!! Thank you for all you do ❤️❤️
Thank you for this fantastic intervention and the public commentary! I'm so glad that the chicks are safe! I learn so much from the cams each year.
Aw! Grateful for keen eyed volunteers and intervention to help our young friends out! 🤗💕
My favorite UA-cam channel, reinforced! The tears are still flowing. Thank you for sharing this. Special thanks to the alert volunteers.
Great job volunteers notice this issue. You probably saved those babies alot of misery or their lives. Thanks to all ,vets that helped them in such a timely manner.
🦜you know, no expert here but I did wonder why one of them seemed tired and not interested in eating much. Thank you volunteer's and those who treated the problem.
Well done to all! With how well your team was able to get the Ms out I am sure both Big Red and Arthur know they were in good hands. How nice of Arthur to bring in a meal for them when they returned!
I bet that felt great to get that out of the ears. What a great job to each and everyone involved
Thanks to everyone involved. Awesome job!
Thank you so much for your due diligence for these wonderful birds. On behalf of followers on another RTH cam we really appreciate your efforts! 😊
I would definitely agree BR has been bringing in more greenery this year and it's interesting to think it could very possibly be for nest hygiene. Such a great nest and experience to observe. Thank you Cornell Hawk Nest Cam ops, BOG's and Vets!
All of you involved in this intervention are Angels. You are Angels!! You are the real Angels. You protect and preserve life, you heal these beautiful creatures. I just love all of you. 😭
You vets were awesome!
Thank you to everyone who helped the M's out! Great job!!
Thanks a lot!!!
Great job.
Be safe, little ones!!
Thank you Cornell for taking care of these beautiful hawks . This is my fourth year watching them everyday and it would be a dream come true to do what you all do. Thank you team. 😊😊❤
Wonderful video! Thank you to all involved!!
You all are Heroes! I'm so proud of each of you for helping. Thank you!!
Wonderful team effort!
Thank you so much for helping these beautiful birds that we all love.
I did notice Big Red pecking near the babies' ears.
Well done to everyone!!! 🤗
Amazing feat! I thank you like everyone else for taking on the task and helping them. 💕
Great job to all of you who helped these birds..
What wonderful care for our little brothers. I admire you, thank you.
Thanks heaps to the people who spotted the problem and the ones who fixed it! Hard to imagine a worse feeling than maggots in your ears.
Oh wow! I mostly only watch during the work week, so I completely missed all the drama last Sunday! I'm glad the intervention worked out and turned out to be a good idea, and that the birds are healthy!
Thank You!
The hawks have a very crudely made ‘nest’. It’s hard to see that it offers much protection. They certainly are adorable.
They somehow have nested there for years. There is another one there I believe. Cornell newsletter is good.
Thank you
Thank you guys 👍 ♥♥♥
Kudos to you guys and huge kudos to the keen eyed observer!! ❤❤❤❤
Thank you for taking care of them.
That is one lucky family of birds to have house-call medical care of the highest caliber.
Thank you so much for helping them. ❤
Very Cool vid...I have been following for some time now. Thanx for all you do...
Amazing work!!!
This is amazing to watch, Thank god you were able to help them.
Gotta say these babies are lucky to have you watch over them. Things like this must happens everywhere in the wild but not all of them are this lucky
thank you
This is why it is so important to give donations to the Cornell Cams. without the cams and extra eyes watching them. The outcome would have been different.
Good works everyone😊
Great job, friends, I appreciated it.
Poor things,,,,thank you for helping them
Wonderful work!
Great work to the whole team! Clockwork! 👏👏👏👏👏
😊 excellent work! Thank you from England.
Great job team!
Caring for creation-great job!
Great job everyone 👍
starting a Falconry course in the UK in July. will be amazing experience to learn about a medieval sport. This video was a great learning process
My great grandkids are asking - What caused flies to lay eggs in the young raptors' ears? Are rotting carcasses in the nest a contributing factor? Is maggots in their ears an isolated issue or regular occurrence?
I'm curious as well!
i don’t believe the flies actually laid in the hawks ears, they likely laid eggs on any leftover prey and when the maggots hatch they move and find a wet dark place to thrive, the ears of a nearby bird definitely check both requirements (anyone please feel free to correct me if i’m wrong about anything!)
As for how the flies got there, it'll depend on what kind of flies they were, but the eggs can be laid directly in the ear, or it's possible that a maggot crawled in. Either way, it's a dark moist place that the larvae like.
Praise God for bringing the right conditions and expert people to provide this good, compassionate care!
We would all love to see the maggot removal from the birds. You should make videos of that. Hugely popular and educational.
Is that Mike Fitz commenting? That man is everywhere!!!
I have not checked in on the babes in a few days. I’m glad this was caught early!
Those hawk parents know how to pick good real estate. Free view of all the games! Better than TV for the kids.
Thanks for doing this great work for the birds. The nest should be dusted off with some diatomaceous earth which will kill the bugs and is non toxic for the birds. Use food grade. Maybe some sulfur powder too or special spray? Wildlife has such a tough time to survive. They need all the help we can give. Mostly habitat loss to humans.
Will you explain why they ended up with maggots in their ears? Is it because of the carrion in the nest?
I'm wondering if you treated the nest with anything before putting the kids back...
They treated the birds to prevent re-infection and mentioned Big Red has been cleaning up carcasses (likely the source of parasites - an eaten squirrel's parasites will be dealt with by stomach acid, but leftovers may have wigglies urgently looking for a new home in) and bringing leaves that parasites don't like, that's probably as much intervention as is safe and ethical. Spraying down the nest or similar would risk dosing the birds' insides with poisons as they moved about on it and breathed it in, possibly giving them new problems down the line and weakening their chances of survival in the critical first year.
As for how the flies got there, it'll depend on what kind of flies they were, but the eggs can be laid directly in the ear, or it's possible that a maggot crawled in. Either way, it's a dark moist place that the larvae like. We don't know the species at this point but hope to learn more from working with entomology here at Cornell. Each of the maggots was around 1-1.5cm long, pale white, probably ~3mm in diameter cross-section. Some studies suggest that 100% of nests in this area have blowfly presence.
Aww thank you so much for protecting and keeping these little red beauties healthy! Hopefully Big Red doesn’t have anything in her ears. Will any of these parasites be in the nest between the wigs? Hope not. Maybe they want to clean the nest and add new twigs when they fly off for the summer. ❤❤❤❤❤
The flies are able to enter the ears of the chicks because there are no feathers to block them.
So happy it was a success!
Wonderful job everyone 👏 ❤
Were they banded when taken out of the nest?
I’ve seen Angel, the leucistic red tail hawk, bringing a lot of pine sprigs to the nest this spring. It makes sense now!
Thank you so much for helping them. I always thought there wouldn't be rescues unless the problem was man-made but this is great! I must not have checked the cam that day as I never saw them missing.
We made the decision to intervene based on the recommendations from wildlife vets and the availability of the right resources in the right time window to intervene safely and with a minimum of risk to the chicks.
@@CornellBirdCams So very glad that you did. Love these birds.
What an amazing bunch of people.
I'm sorry if I missed it, but were there any more maggots in the nest? We're you able to clean some of it out without disturbing the nest? Or is that something the momma will naturally do throughout this process?
The nest wasn't overflowing with maggots-As for how the flies got there, it'll depend on what kind of flies they were, but the eggs can be laid directly in the ear, or it's possible that a maggot crawled in. Some studies have suggested that 100% of red-tailed nests in this area are affected by blowflies.
@@CornellBirdCams Thank you so much for taking the time to answer.
Good job! I'm sure the babies are much more comfortable. ❤
could someone explain why this was happening? i saw many nests over afew years now but i never ever saw or hear that hawklets got maggots in there ear. Here it was all 3 having it! Thats sound pretty uncommon to me. Last year the same nest had not one hawklets with that issuse.
Oh and i would like to know how big were the maggots, how long they were there? what kind of maggots? and so on.

Any idea how this happens?
Hello, I was wondering how you knew the babies had the maggots in their ears that required this intervention? Great job by everyone involved! Well done! I’m just curious how you became aware that the poor babies had the maggots? ❤
Sharp eyed cam viewers noticed. More info in the description box
Beautiful
Ewww! Maggots! Not even baby hawks are safe! Good work, team.
OMG! This is awful! Thank you to the Dr., his crew, the volunteers, and everyone else involved in diagnosing and treating these beautiful hawklets.👏👏👏❤️❤️❤️. It's wonderful that they were treated and returned to the nest.
This is all new to me, so I have questions. Was the prey that was brought in infested with maggots?
I can believe Joe Rogan took bird ear dewormer for COVID-19. 😏😂
I see the hawks standing on grates and see all ants or bugs in nest, I never saw them stand on grates before, guessing another bug infestation? Can you check nest for bugs and that hawks ok? Thank you so much for all you do!
As they get older they venture out onto the grates and around the nest site. Thanks!
I love that Arthur brought some leaves--maybe the get the smell of the humans off the chicks! :)
How do maggots get into bird's ears?
awesome
Yes a great job. I don't understand: isn't the entire nest filled with maggots? Why will the birds not become reinfected?
As for how the flies got there, it'll depend on what kind of flies they were, but the eggs can be laid directly in the ear, or it's possible that a maggot crawled in. Either way, it's a dark moist place that the larvae like. We don't know the species at this point but hope to learn more from working with entomology here at Cornell. Each of the maggots was around 1-1.5cm long, pale white, probably ~3mm in diameter cross-section. Some studies suggest that 100% of nests in this area have blowfly presence. Once the chicks' ears are feathered (which they just about are), they are no longer at risk.
Could sleeping on the leftovers be a contributing factor to having maggots in their ears? Or are there flies that like to lay eggs in birds’ ears?

Did they treated the nest?
No, the nest appeared to be ok.
Thanks 😃🙏☯️🙏
what species of maggot?
Not sure yet.
I have noticed over the years of watching birds that come to my yard that they take beak fulls of certain herbs that I consider insecticidal. I always figured they knew which to take but I don't know how they know. Just thought it a magical moment.
I have seen Bald Eagles, like one in Florida bring sprigs of evergreen to the nest. They obviously know what they’re doing!
@@spnkysy791 I wonder if anyone has ever done research on the "greens" brought to the nests to study what compounds the birds are searching for.
Wow !
