Beaking and hurricanes…and other news in Bird World on Wednesday

28 September 2022

Good Morning Everyone,

My thoughts are with everyone and anything that is in the path of Hurricane Ian. So many of you live in this area and my thoughts are with you and your families and our beloved birds and their nests.

This is the latest image of the eye as it moves. The wind at Captiva is currently 94 kph (or 55 mph). All of the streaming cams are down at Captiva and SWFlorida. The eye of the storm at 12:43 is moving towards Captiva/Sanibel.

Making News:

I started writing this blog on Tuesday so you will also be getting some hurricane news here (as well as above). Here is the news on Hurricane Ian. As I write this, the eye is approximately two hours from making landfall which could make landfall at around 1400 and that hit could come at Sanibel/Captiva. This is live coverage. NOAA is the only institution that can declare landfall and where/when. It looks like this huge and strong hurricane will impact all of our beloved nests. We will be so glad to see them when this is over.

This streaming station was working. If it should go out, check on YouTube for others that are covering this massive hurricane.

Farnley, a female fledgling of 2022, is making news as she continues to work her way south in the UK while she is thinking about migration. I note that in the long list of beautiful images of this juvenile, towards the bottom is an image of her catching a good sized fish. Most of the fledglings will never have caught a fish before they leave the nest for their journey to their winter home. We worry that they cannot do it. Well, if Farnley can so can the rest of them we hope!

Update on 1B3/Farnley | Kielder Ospreys (wpcomstaging.com)

It is now 2136 on the Canadian Prairies on Tuesday. This is the current satellite map and the cone showing the wind strength of Hurricane Ian as he moves towards making landfall near Tampa/Fort Myers as a category 4 hurricane.

At 22:25 Tuesday evening, the eye of Hurricane Ian was 100 miles from the Captiva Osprey nest.

Rita came in to check the status of her nest at 0845 this morning.

The platform at Captiva Ospreys was rocking and rolling with heavy rain drops (or hail) when it quit working around 0335. The Southwest Florida Bald Eagle cam is down and this is the view at Northeast Florida and the nest of Gabby and Samson.

Nest News:

Well, it has started – the beaking. It was Middle Bob giving Big Bob quite the headache. Little Bob looked the other way and ignored it. The behaviour, as predicted, began when Big Bob went into the reptilian phase.

Big Bob is miserable with all the itching from feathers growing in. It is Day 9 and this behaviour is pretty much right on schedule – it began yesterday. It is about nest dominance. I have included tonnes of screen captures because I have yet to import my little video programme I use. I hope you don’t mind. Some of the physical gestures and looks are quite interesting.

You have to feel sorry for Big Bob. Just look at him. You can really see how the soft down is leaving Big Bob’s body and being replaced by feathers. We saw this yesterday clearly happening. There is sweet Little Bob with its soft down. Each osplet still has their egg tooth.

The down from the back of Big Bob’s head is almost entirely gone. There are a few whisps of dandelions and a bunch of dandelions on top of his head.

Now you can see the back of Big Bob’s head. Slick and oily black. This will become magnificent coppery coloured feathers.

It all began with Big Bob hammering Middle Bob as Little Bob looks on.

And then Middle Bob got fed up and when Big Bob turned around, he gave it to him. These two would have a ‘draw’ if they were in a boxing ring. Meanwhile, Little Bob is on the other side of Middle Bob looking in the opposite direction.

I did say evenly matched but Middle sure did give Big a thrashing.

The Middle Bob moved over and Big Bob beaked Little Bob just because he was in the wrong place at that moment.

And then Mum finally sat down on all of them. Thankfully Little Bob did not get too much of a thrashing from Big. The beaking stops when dominance is established and normally by 28 days. Of course, siblings can be killed. The dominant bird normally gets fed first and will eat til it is full then the others can have their fish. If the deliveries fall short, which they have certainly done, then there can be death. I do not believe that is going to happen on this nest unless there is a sudden and long lack of fish deliveries. It will be an interesting outcome because Middle Bob is very strong. Let us hope Little Bob keeps getting lots of fish! He needs to grow. Middle Bob will get really cranky when his feathers really change which could be tomorrow late or the next day. Nothing like two itchy rivals in a nest!

The new male has made a stop at the ledge of the 367 Collins Street scrape. The Mum was kerchuffing and they had a bit of a conversation. She had been looking down at the eggs and, she did not leave right away even if lunch was waiting for her elsewhere.

The Mum has been quite restless. I wonder if we might have eyases for the 29th in Australia?

The Sea Eaglets are a bit worrisome. They are so energetic, jumping and flapping all over that nest. Last year SE28 fludged because of this kind of activity. They sure look like they want to fly but, I have not seen them self-feed properly. Have you? That is what I mean by worrisome.

Look at the height achieved in the last image.

Xavier and Diamond wait with one another. We will be ever so excited – like these two lovely parents – when those eggs hatch.

Thank you so much for being with me today. We are sitting on pins and needles for the hatch at the Melbourne scrape. The Sea Eagles will continue to bounce and flap higher and higher. Let us all hope that the PLo nest is flooded with fish and that things go smoothly there today. Please take care of yourselves. See you soon.

Up Close with Ervie

Port Lincoln gave everyone a real treat today by getting up close and personal with Ervie when he was on the perch.

Alan Poole calls the feet the ‘business end of the osprey.’ You can see the rough sandpaper bottom of the feet that stops the slippery fish from falling off and that reversible toe that swings backwards to hold the fish taut. The hooked talons join the barbs on the bottom of the feet and that amazing reversible toe to give the Osprey or ‘fish eagle’ its advantage when diving for its dinner.

I have never touched an Osprey. Would I like to? Of course, if it didn’t stress them out. If I were to rub the feathers of an osprey, Poole tells me that they would feel oily. The layers of these waterproof feathers really helps this raptor that will be diving (if a male) many times per day during the nesting period to feed his family. Of course, the females fish, too. Some better than their mates.

Ervie has something caught in his beak. It looks like an old piece of fish skin. He has been rooting around in the nest for leftovers ever since Falkey got the breakfast fish. Hopefully that old skin will dislodge.

Ervie’s beautiful juvenile feathers will wear out and will need to be replaced. It is called molting. The osprey has adapted for the feathers to be replaced gradually without disrupting their ability to fly and fish.

As an adult, Ervie will not have that beautiful white tip to his back and wing feathers. The plumage on his head will remain in the same pattern. Sometimes the pattern on the crown of the head is so distinctive that an unringed bird can be identified simply from that formation.

There is Ervie on 4 October. He was only 20 days old. A perfect little reptile waiting for the fish. Ervie was always my focus because he was the third hatch. I believe, however, that is Bazza closest to your screen with Falkey out of view. Ervie loved his fish just like he does now and he always liked to have his breakfast first. He was not shy about getting in the line even if Bazza tried to dissuade him.

Today, however, Falkey seems to be the only one eating. He landed the 06:55 fish. Bazza then found an old piece of fish and Ervie took that (probably what was hanging from his beak). Dad came with another delivery at 09:21 and Falkey got that one, too. This didn’t sit too well with Ervie and it got him a little agitated. Ervie starts fighting with Bazza while Falkey eats away. Both Ervie and Bazza wind up on the deck again. Will this be their time out corner?

Ervie pushes Bazza out of the nest backwards.

These two have been very lucky that they did not go in the water.

Just look at Ervie’s eyes. Bazza may be his sibling, the one who picked on him when he was younger but, I don’t feel any ‘love’ between these two.

By 09:56, some 35 minutes later, both brothers are back on the nest.

Eventually Ervie flies over to the other side of the ropes, Bazza and Falkey are in the nest (surely Falkey cannot eat a third fish), and Mum and Dad are in the shed or man cave. Everyone is screaming at Dad for fish. It reminds me of Emyr Evans saying that Ceri would be screaming her head off at Monty wanting fish and she would be standing on one. Endless pits. These Dads sure need to be fit if they are going to do a good job of providing for these big chicks.

Ervie is no shrinking violet, that is for sure. I am surprised, however, that he struck out at Bazza and didn’t go over and take the fish from Falkey. The day is young. It is not even noon on Sunday 21 November. Lots can still happen. Maybe Ervie will decide to try fishing. Now that would be simply grand.

Thank you so much for joining me. Take care!
