Tiny Little, Blue 35 and the fish – and other tales from Ospreyland 13 July 2021

I wanted to yell as loud as I could, ‘Go Tiny Little!’. There was a fish drop at the Foulshaw Moss Nest. Blue 462 had it in its talons.

Oh, what I forgot to tell you was that Tiny Little kept trying to steal that fish from Blue 462. Look at Blue 35 (mum) watching what is going on.

Tiny Tot finds the tail of the fish between Blue 462’s legs and trys to eat the fish from there! My friend ‘L’ says that Tiny Little is a ‘hoot’ – he is!

Tiny Little bothered his big sister so much that she moved the fish to the other side of the nest! But Tiny Little did not give up. He was more determined to try and distract Big Sister and grab that fish. Look how mum is watching everything that is going on. Tiny almost gets that fish a few times but he is not fully confident nor aggressive yet.

It must have been uncomfortable for Blue 462 to have Tiny right up there by his face. That is probably the point. At one point it looked like Tiny Little tried to grab the fish out of 462’s beak as he was pulling it off the bone.

Tiny Little pleads with mum to do something about that fish because he wants some of it and Blue 462 won’t share! Now Tiny Little didn’t do this just once, he went to speak to mum several times. There was, of course, no mention of Tiny Little finding that entire fish and not sharing it with anyone earlier!!!!!!

Blue 35 watched everything. What a smart mum she is! She waited and checked and then waited and when Blue 35 felt that Big Sis had enough fish, she walked over, took it, and flew away with it.

Here she is moving in to take it from Blue 462’s talons.

She pulls it over and once she has that fish secured she flies off the nest.

Why did she take my fish? says Blue 462. Tiny Tot is bewildered. He figures that is it for his bedtime dinner. Even Big Sis can’t figure it out. They stand there staring into space wondering what just happened.

Ah, Blue 35 wanted Big Sister off the nest. She took the fish and when the older sibling had left she returned to feed Tiny Little.

Ah, what a good mum Blue 35 is. She makes sure every one of her three babies has some fish.

When Tiny was full and off cleaning his beak, Blue 35 enjoyed a few bites of fish herself before Blue 462 flies in to try and get the precious fish tail! Mom starts feeding 462 again.

Wonder where 464 was? Did White YW give him a fish off camera?

Looks like Tiny Little won’t be sleeping alone tonight. Blue 462 is tired from all that flying! Both of these big babies have full tummies. Time to go to sleep.

As the sun was setting in Wales at the Dyfi Nest, Idris was out on his perch, Telyn was on the nest perch, and both Dysynnis and Ystwyth were on the nest ready for night-night as the train speeds by.

Over in the Clywedog Nest, Seren 5F was feeding Only Bob, Blue 496, his late night snack. He earned it today – he made a proper fledge this morning and he must be awfully tired. Gosh, this kiddo is big. Look at those legs!

As the pink of the sunset was coming over Loch of the Lowes, NC0 was on the nest watching her children, LM 1 and LM 2 as they flew around the loch.

Hopping to North America, Wattsworth and Electra were on the Cowlitz PUD Osprey Nest in Longview making a few nestorations. They lost both their chicks this year. The first to siblicide and the second to heat stroke during the 28 June extreme heat wave that hit the Pacific Northwest.

What will the Ospreys do as our planet heats up?

I don’t know if there are any repercussions on the Ospreys in Alberta from the smoke and fires to the west of them in British Columbia. Let us hope not. Legacy is growing and growing at the Red Deer Nest. It was hard to get a good image of her today but she had just finished a nice breakfast when I took this one.

And the two on the Fortis Exshaw Osprey Nest are progressing nicely as well. They are also growing really well now that the extreme heat is gone.

Kindness is 89 days old. She is on the Glacier Gardens Bald Eagle Nest up in Juneau, Alaska. She has been practicing her standing and is getting really good at it. Kindness is a ‘Northern’ Bald Eagle – not a specific species but because she is higher north in the Northern Hemisphere, she will be heavier and bigger than birds in the southern US. This is called the Bergman Allen Rule. Northern animals are typically heavier and larger than the southerly ones. This is related to the climate and physiological differences and their needs. The female Bald Eagles in the north, like Alaska, weight 4.5-6.35 kg or 10-14 lbs while in Florida the top weight for a female Bald Eagle would be 6.35 kg or 10 lbs. The males in Alaska are 3.62 -4.9 kg or 8-11 lbs while in Florida they are about 2.7 kg or 6 lbs. The average day for fledging at this nest is 89 days. (The average age for Bald Eagle nestlings in the rest of Alaska to fledge is 80 days). So we have some time yet with Kindness! Terrific.

Thank you so much for joining me. It was great fun with Tiny Little today. If you watch that nest check out Tiny Little’s rather ‘fat’ legs. Tiny Little is growing so much now that there is this notion that Tiny Little is a girl. Maybe we will find out one day. Take care everyone.

2 Fledges in Ospreyland — and More and more threats to their health

Let’s start off with the fledges. Wow. They almost happened simultaneously.

Only Bob, Blue 496 at Clywedog, the son of Dylan and Seren fledged at 12:34:54 on 12 July.

And he’s off. He first flight was short but it was a fledge – he went to the camera pole. Congratulations Only Bob!

Dysynni, Blue 490, fledged from the Dyfi nest, the son of Idris and Telyn, at 12:26.

Gorgeous take off! Congratulations.

And now to the serious stuff for the day. It is wonderful to see the birds fledge but we need to take care of them afterwards.

If someone stopped you on the street and asked you to list all of the threats to the well being of our beloved Fish Hawks, what would you say? Think about this and jot down as many issues as you can. You can even use some historic examples because in parts of the world some of those could still be threats.

  • Methamphetamines. The Smithsonian Magazine picked up a story running in several newspapers about a week ago. That article focused on the minute amounts of meth amphetamine that were in the water and that the fish had gotten addicted. The diet of Ospreys is fish. How might this impact the adults and their chicks?
  • Fishing Equipment. Every year adults and chicks alike get tangled in monofilament fishing line. Without doing any research to find the latest examples, there was the incident of the dead Osprey near London, Ontario about a month ago and just a week ago Fortis Alberta was called to the Red Deer Osprey Nest to remove monofilament line around the only surviving chick on that nest. I am going to guess that anyone reading this will have several examples. Then there are the hooks. And hooks attached to monofilament line.

  • Non degradable Baling Twine. The banders who went to Warm Springs, Montana, found four chicks entangled in bailing twine. One had died. It took 20 minutes to remove the twine from another chick. The twine was so tightly wound that it had cut through the skin and had halted the chick’s circulation. As a result the chick was in pain and the leg was very swollen.

  • The impacts of climate change can include a long list of side effects. One of those is heavy winds that can tear down trees and nests.
  • The impacts of climate change can include a warming planet. Everyone witnessed the high temperatures that hit the Pacific Northwest (the US and Canada) recently (June 28). Heat kills Osprey chicks that cannot regulate their own temperature to survive. The heat also causes the fish to go to the bottom of the river or lake so that they are difficult to catch. This causes the birds to become dehydrated and die if there are not sufficient deliveries. You can probably name several nests where you witnessed chicks die due to the heat. Ospreys want open nests or platforms where they can see the environment around them. Because of this the nests are not shaded and the temperature on the nests can be higher than that reported. The sun bears down on the little ones and they die quickly. A good example is the Cowlitz chick. Electra went to get fish despite the fact that the chick had a crop. Temperatures were in excess of 40 degrees C. The mother was only gone from the nest for a few minutes when the chick began calling for her and died of heat stroke. Osprey chicks in British Columbia and in Alberta also suffered death from the high temperatures.
  • Decline in fish stock numbers due to pollution, high temperatures, and drought. The diet of Ospreys is 99% fish and if the fish numbers are low, the Osprey have nothing to eat.
  • Snowpack. Warming temperatures mean that there is less of a snowpack at the top of the mountains. The snowpack will melt faster causing flooding making it difficult for the Osprey males to catch fish when the chicks are hatching.
  • Mine waste and heavy metals. Eric Greene studies the toxic heavy metals in Montana from the old mining sites. He tests for these when Osprey chicks are banded. He has found 30% more arsenic in 2018 than he did when he began his study in 2006. Greene has also found very high mercury levels that result in egg mortality. The rate is up to 50%. Greene also found that the level of mercury in Osprey chicks blood is 100 times higher in the chicks than what is considered a problem for humans. Imagine. In other areas of the Clark Forks River, there is so much dioxins, furans, and PCBs that humans have been told not to eat the fish. The Osprey continue to eat the fish and feed it to their chicks. I do not know if you can open it but here is a report from Montana on the clean up and issues related to heavy metals in the Osprey:

https://hs.umt.edu/osprey/heavyMetalStudies.php

  • Soil Remediation to remove the contaminants from the rivers causes a temporary decline in fish stock.
  • Egg collecting. In the late nineteenth century and early twentieth, the collection of Osprey eggs was very much ‘in vogue’. This caused the numbers of Osprey to decline significantly. There remain some egg thieves today. The eggs of Osprey were considered the most beautiful and were highly prized. A man in the United Kingdom, Mark Gonshaw, was convicted of illegally acquiring eggs of endangered species including eight Osprey eggs in 2011. He had more than 700 eggs in his possession and on 22 December 2011 he was sentenced to prison. You can read about this here: https://focusingonwildlife.com/news/british-egg-collector-sentenced-to-prison-term/
  • Vandalism. A good example is the instance when one or more persons came to the Lyn Brenig Osprey Platform where there was egg/s and cut down the platform with a chainsaw.
  • Shooting. This year it is known that at least two Ospreys were shot over Malta on their return flight from Africa to their breeding grounds in the United Kingdom and Europe.
  • Other Birds of Prey or Animals. Other birds and animals often predate the eggs or take the chicks out of the nest such as the attack on the nest by a Northern Goshawk in Latvia recently. Great Horned Owls are also problematic as are Ravens who love Osprey eggs.
  • Urban Development and loss of forest habitat.
  • Power Lines. Many power companies are now creating artificial platforms so that the birds are not electrocuted on the lines.
  • Pesticides. Ospreys were the first of the large raptors to warm about DDT. Today DDT still exists in the soil of some areas and causes reproductive and thinning of the egg shells.
  • Poor Water Quality. You might recall that there was an enormous spill of toxic material into the water near the Sarasota Osprey nests. Those toxins will spread with the flow of the water.
  • Hypothermia. Hypothermia is believed to be the cause of the deaths of the surviving two osprey chicks at the Urdaibai Biosphere in Spain.
  • Human disturbance. Ospreys are much more tolerant of humans than many of the other large birds of prey. Still humans can come near the nests and frighten the birds causing them to abandon their nests with eggs or chicks.
  • Avian Flu. The impact from this is not clear. I continue to research.
  • Competition within their own species for nests and territories.
  • Competition within their own nest.

You have probably thought of many more ways that these beloved birds are threatened. I would love to hear from you!

I will leave you with a couple of images of Tiny Little taken around 6:15 am Monday 12 July 2021 nest time. Tiny you are not looking so Tiny! No one needs to worry about you and that is fantastic.

Tiny Little seems to really be enjoying himself up on that perch instead of being on the soggy nest this morning. Look at those wings. Tiny Little has grown like a very bad weed in my flowerbed. Unbelievable! Maybe that bander is right and he will be the second to fledge! We wait. This afternoon, Little Bob was getting some bites in between Fledgling Bob, 464 being fed.

Thank you so much for joining me. Stay safe and take care. See you soon.
