Late Wednesday in Bird World

6 July 2022

The beautiful day gave way to heavy rain and dark grey skies. Manitoba is water logged.

It was fantastic to have the commentary of someone actually watching Idris catch this fish – it took him 5 tries to pull it out. I do wish the cameras gave us a better idea of the size of some of these amazing catches. The ‘girls’ of Dyfi were appreciative of his efforts.

The three females now take up more than half of that big nest. Eating, sleeping, growing, and getting their flying muscles stronger. Sleeping now!

Hi Dad!

Telyn arrives to feed the girls.

One of Wales Osprey couples – Aran and Mrs G. Mrs G is the oldest osprey in the United Kingdom. She is very dark with a large necklace. Dorcha at Loch Arkaig reminds me so much of Mrs G. I love Aran with his penetrating eyes.

Dorcha has, perhaps, even slightly darker markings than Mrs G.

Louis does not fail to deliver the tea time meal to his Loch Arkaig nest – he is an extraordinary fisher.

Speaking of crops – the female osplet at Loch of the Lowes has quite a large one this evening! Blue NC0 looks tired to me this season. I hope these two fledge and give their Mum time to replenish the weight and fat that she has lost caring for them before she leaves on her migration. The females leave about a fortnight before the others. That is, however, an average as nests can vary greatly.

The two chicks at the Mispillion Harbour Osprey nest were happy when a fish arrived too…what is with feeding them when they are resting duckling style??

Wonder what they are looking at?

Neither of the two appear to be overly hungry. Thank goodness. It looks like a teaser.

At the Boathouse on Hog Island, Skiff brought in a really nice fish. Big was full and Middle and Little got a really nice feeding from Dory. This is just wonderful to see!

In Montana, they are ringing/banding all of the Osprey nests. If I recall there are about 200 along the Clark Fork River. Those who make up the Montana Osprey Project will also test the birds for toxin residues that remain in the water and the fish from the mining around Missoula. Here is an article with some images of the events.

How many successful Osprey nests fledge 4 chicks? Maya and Blue 33 did it two years in a row. This year it is a Kielder nest and there is a short but nice article in the BBC celebrating this great achievement – and it is. Some nests do well with 2 but give them 3 chicks and there are often problems. 4 chicks would keep Mum and Dad busy 24/7. Ironically the literature on siblicide notes that the % of events is higher in nests with 3 chicks than with 4.

Two of the fledglings at the West End nest have locked talons and fallen off the nest! I am not 100% sure who the pair were but I think that it is Ahote on the nest and Sky coming in but – without seeing those bands it is so difficult to be certain.

The talon tumble happened yesterday and as far as I know both fledglings are fine – just their pride wounded a little.

The other fledgling can be seen flying in the distance. The one on the nest is alerting.

The one on the nest goes up and lunges forward.

Talons engaged.

They go down and then without having good footing both tumble down the cliff talons engaged with one another.

There is something very strange going on in Mlade Buky. Bukacek is building another nest! The storklets are watching him. This could get interesting. Does anyone know about this behaviour?

There is Bukacek down below the nest. Some of you may remember that the two engineers that set up the camera and saved the storklets last year when Bukacek’s mate died, did sometimes put fish down in that area. I wonder what is going on??

What is a crop? The crop is a muscular pouch. It is part of the bird’s esophagus and is used to store extra food before going being digested. Often birds will eat and eat and eat – because they do not know when they will find more food. Thank goodness that crop is expandable. Vultures and condors are known for filling their stomach and then eating – if there is enough prey – until their crop is entirely full. Some birds that regurgitate food for their young often use the crop to soften it so the wee chicks can eat easier. Hawks, vultures, condors, eagles, falcons – they all have a crop. Pigeons and doves use the crop to produce ‘crop milk’ – pulverized food – that they feed to their babies.

One of Karl II and Kaia’s storklets today with an extended crop.

Do you live in the UK? Near Rutland? ‘L’ just reminded me that the annual Birdfair will take place on the 15, 16, and 17th of July. Here is the information in case you want to attend. Thanks ‘L’! If you do ever find yourself at Rutland, please go on the water tour. You might be lucky enough to see Blue 33 land one of those huge fish he brings to Maya.

This has just been a hop, skip, and a jump to check on our nests. It appears that all of them are doing alright. No strange events – unless I have missed them! In that case, please feel free to let me know.

    Thank you Mary Ann for the updates. Glad that all seems ok here for now and pray it continues to be. I don’t know what is happening at the stork nest but maybe it is a food delivery hopefully.
    Have a great evening and we will be looking forward to your newsletter tommorrow!
    Linda
