Osprey Live Chat with Dr. Rob Bierregaard

Tune in on Monday, June 11th, at 4pm ET/ 1pm PT for an Audubon Society live chat about the osprey nest. Dr. Rob Bierregaard will be joining us as he gives us updates on the newest osprey chicks on the Hog Island nest and any other information pertaining to this past bird season!

Make sure to watch live here and submit your questions below!

    Hi! There was a hail storm last week at another nest which was on “pip watch.” Mom Iris protected her eggs, but it made me wonder what would happen if an egg suffered a small crack just days before it was due to hatch. If the chick has already started to breathe in the air sack, could it survive a small break? Thank you!

    Hi Dr B! I’m wondering if and how the very close hatch dates will influence the chicks’ chances for survival. Could you please elaborate on this?

  • Sherrie P

    I was wondering if Bailey heard a recording of her parents calls, would she recognize them, given that there seems to be no interaction of birds with their parents once they fledge?

  • Julia Glueckauf Gray

    I would like to know; some of the behaviors of the chicks are instinctual, but how much is learned by example from parents? One example is their pooping; they seem to automatically know to back up to the side of the nest to shoot. Thank you

  • Marian Swenson

    Last year after the gho captured two of the chicks, Rachel moved closer in to Bailey on her perch. It seemed to me that had a lot to do with her being close enough to fight off the GHO. Do you think that is a learned behavior and do you think she will do the same behavior this year when the chicks get bigger?

    Hello DR B, Iam in Newfoundland where you tagged a mom on Snow’s lane, dow the road from me, know she did make it down south, was wondering if you plan on coming back here and what does the male do now?, he is here working on nest at times, will he try to find new female here, and how will that happen ?, watching the live cam here now at times. Thanks you for all you do!!

    When the ospreys winter in warmer areas, do all the males from northeast US go to the same place(s), and all the females go to a different place(s). I know the pairs do not winter in the same place. Or do they just head south and find out who their “neighbors” are when they stop? Do they tend to go back to the same winter homes? I was thinking of all this as the hurricanes were so violent in the Caribbean, and wondering how the ospreys were affected. Thanks!

    • Cookie Steward

      Great questions. I too was wondering how the hurricanes effected their migrations last year.

  • Suzanne

    Hi Dr. B! Is there a link to the BBC documentary about migration that you were involved with? Would love to watch it! Thank you!

  • Sammie

    Rob, What is your best guess regarding Rachel repeating the adaptive behavior she used to protect Bailey from the GHO attack last year? Do you think she will remember that or will it be done in reaction from a threat? Have you heard of a female osprey doing this before?

  • cmolander

    Thank you for chatting with us and answering our questions, Dr. B. My questions relate to the legs and feet of the osprey.
    Osprey, and other birds, have scales on their legs and feet. Are these scales replaced one at a time, or do they sloth off as a snake’s scaly skin is shed? How often are they shed? What is the significance of these scales to osprey?
    (If you have time) Could you also discuss the talons. As we know, cats stretch and sharpen their claws by scratching to remove the worn claw. How do the osprey sharpen their talons?
    Thank you, AKA MrsMo

  • Cookie Steward

    Hi, I am wondering if Rachel and/or Steve have memories from past years that they have learned from in order to protect their chicks? Will they stay closer and on higher alert after what has happened in the past. And have there been efforts taken to keep the bees/wasps away from the nest this year? Thanks to all for providing us with this platform and to the camera operators and mods.

  • PhilStubington

    Do Ospreys over fall out of the nest or accidentally knock each other out?
    I’ve seen it happen at multiple eagle nests and was wondering if the same happened with Ospreys. If not, do you know why not?

  • Sherri

    I don’t understand why Iris at Hellsgate does not feed chick#3. I don’t think It’s going to make it. Why we she not walk over there and feed her. I know it’s the strongest but, it is hard to watch.

  • KD J

    Have there been a nesting pair at the boathouse nest the same time as Rachel and Steve? I don’t understand why it is so close. Is it a frustration nest for Steve?

  • Diana Lambertson

    Dr. Bierregaard Late last nigh Rachel was on high alert giving warning calls Do you think it is possible she remembers the GHO attacks last year and will be extra diligent in protecting her chicks this year?

  • 4meowsmom-MA

    First a big thank you to Dr. B for taking the time to chat with us!
    I would like to know if 3 eggs is an average clutch each year for Ospreys
    and if you see more boy or girl babies being born. Thank you!

  • Diana Lambertson

    Why don’t you Think Dottie and Doug or any other osprey pair used the boathouse nest platform?

  • Carl Williams

    As I recall, a pathogen was transmitted from black flies to the Eaglets at the North Deborah nest, killing them. Are Osprey chicks susceptible to the same thing?

  • palurien

    I have your book, Belle’s Journey, and just want to say I really have enjoyed it.

    About what age do the young chicks stop being aggressive/bonking one another?

  • Matthew Halley

    Hey Rob, is it better to arrive early on the breeding grounds in less than tip-top condition, or to arrive a little late in A+ condition? Is the benefit of arriving early condition-dependent?

    Why has there been so much competition for nests this year? don;t they use the same nest each year?

    Questions from the National Audubon Society FB chat:

    Why would an osprey choose to Nest right next to a main road? Why do some choose to be close to human architecture while others are so sensitive they’ll abandon a nest if people get too close?

    How does an Osprey’s vision differ from that of humans?

  • fluffyspun

    Have any of Steve and Rachel’s older chicks been spotted nesting anywhere?

  • Diana Lambertson

    Has there ever been a trio nest with Osprey?

  • PD

    [from Audubon FB live chat]

    After hurricane Irma – I was sad to see a nearby osprey nest destroyed. I was surprised to see how fast they rebuilt, and had young. Why do they rebuild in the same place rather than move?

  • Anne Hall

    last summer near Blue Hill I watched what appeared to be an osprey fight off two bald eagles high in the sky. it went on for quite a while. there is often an osprey in that area, so might have been a nest as well. do bald eagles often raid osprey nests?

    • BillHistorian

      Osprey are frequent visitors around milton landing on the neponset river …..it’s common to watch little sparrows and the like dive attack on eagles too close to their nesting area…….

  • Diana Lambertson

    is there anyway of knowing the origin of Bailey;s injury? The owl attack the fall after the wasp attack the eagle attack her being injured in transport?

  • PD

    [from Audubon FB live chat]

    What’s the oldest age an Osprey can still lay viable eggs?

  • Anne Hall

    in europe, where I live, people build platforms for storks on which to build their nests. you mentioned ospreys like cell towers – is there any need to build platforms for ospreys or are they doing well enough without?

    • Teanna Byerts

      I’ll add to this by noting a gazillion nesting platforms all around the Chesapeake Bay area, as well as on lakes in southcentral PA (top of the bay). They also seem to love channel markers.I wonder too if they’d be lost without the platforms, but there are sure a lot for them!

  • Diana Lambertson

    Does the male take over care after the chicks fledge?

  • Diana Lambertson

    is there any scientific proof that GHOs can see better in IR lighting?

  • Teanna Byerts

    Ospreys seem to be far more tolerant than eagles… true??? Our local (York COunty PA) eagle nests’ locations are a closely guarded secret, or if known, have borders you can’t cross quite far from the nest. Meanwhile, the osprey nest on Lake Marburg is on a pole on an island… there are markers, but you can kayak fairly close and be outside the buoys. Same on the Chesapeake, you can boat right past most of the nests, or otherwise pass fairly close…compared to eagles anyway. Why such a difference?

    • BillHistorian

      two Eagles are near my boat, moored on the Neponset River, Mass., One eagle will fly off quickly if I am near them, the other will look on as if I am the next door neighbor.
