Good Morning Everyone!

Oh, one half of the sky is blue with cottonball-like clouds. The other side is a solid mass of heavy grey clouds. It is 22 C and more rain forecast for 1700. The Crows are already in the bird bath eating their ‘sandwiches’ and peanuts. Given a chance tens of sparrows gather in there after they have left. The squirrels are running about and the birds are flitting in and out. Dyson came to drink out of the bird bath yesterday and all the rabbits have been here. The weather is hot for here and having water out for the animals is, hopefully, helping them to cool down. It is so reassuring – just like when we check on the streaming cams and everyone is home!

The three young Crows are constantly with one another. Their flying is improving. The bird bath water is in constant change for one reason – everything is washed by the Covids. I wonder if it was to soften the shell of the peanut??

One of the fledgling Blue Jays waited its turn until the Crow departed.

This Blue Jay is yelling at Dyson! The squirrels do not wait in line – they just go and grab the peanuts. It is too funny. The juveniles are just getting their crests.

Poor Junior. He is moulting. If you see a Cardinal or Blue Jay looking scarce on top, they are not ill, just replacing their feathers.

Hello Dyson. Thank goodness the new bird bath is heavy enough that Dyson doesn’t go flying when he jumps up for a drink.

Adorable Hedwig. He spent about an hour eating the spilt seeds under the feeder. Hedwig was discovered under the Peony bush. He was such a wee rabbit. He never left the garden but ate the seeds as the birds flitted around him. He is never frightened by them. His burrow is somewhere else now but you can always count on his arrival around 1730 rain or shine, winter or summer. He’s an Eastern Cottontail.

Olsen really seems to have outdone himself on Sunday. As I begin to write this, there are two partial fish sitting on the nest. The chatters have been keeping close tabs and ‘H’ provided detailed time stamps. These are invaluable for viewers coming on line. Much appreciated. By 0900, Olsen had delivered 8 fish of varying sizes. Everyone was chock full of fish. It appears that there was some nibbling on the old fish (gosh they must be like dried fish now!) with another fish delivery at 18:33.

Soo has done a fabulous job keeping the chicks shaded. It is currently 37 C but rose to 40. Or 98.6 F to 104 F.

The nest still has horrific temperatures tomorrow. They seem to just keep adding on an additional day of heat. When did I ever believe I would say that 34 C was a welcome drop in temperature? The night will be welcome cooling off periods. The Osprey parents are doing the best they can and thank goodness those two chicks are feathered nicely this year.

Send positive thoughts, please. Soo and Olsen deserve success. In 2020 they lost a chick and one fell out of the nest and in 2021 the three died in the heat dome that stayed over the area. This year we have had one fall over the nest so let us keep fingers crossed. I think Soo and Olsen will succeed this year.

It is now Monday morning and Olsen has already brought at least five fish according to the chatters and here he is at 0656 feeding his babies fish number six!

I do not know if you have read the history of this nest but it is one of those great cooperative measures. FortisBC worked with the Town of Osoyoos put up a separate de-commissioned hydro pole for the Osprey and also donated the funds for the camera – the nest and streaming cam you are watching. They were proactive – indeed, it is in their best interests not to have the local power knocked out but, grateful, so grateful.

It is cooler at the Fortis Exshaw Nest in Canmore, Alberta. Mum and the trio are doing very well it seems.

Because it is in the same heat warning area, I have been checking on and off at the McEuen Park Osprey platform in Coeur d’ Alene, Idaho.

There were two of the fledglings on the nest when I popped in.

With all the heat warnings, it is nice to have something to laugh at and it is provided by Bukacek and the adult only nest. You might well remember that Bukacek had built a second nest for him and Betty. Having four large White storklets on the natal nest gets a little crowded. Now that the storklets are flying – they have taken over the new nest! Bukacek will have to build another!!!!!! Betty meanwhile lures them back to their own nest with food. Perfect. Ooops….they ate and left. Oh, goodness.

Beautiful Betty.

There has been some concern about a blood spot near the wing of SE30 on the Sydney Sea Eagles nest. What was the cause? Often the eaglets get fish blood or bird parts on their body but this does not seem to be that. It looks instead as if some feathers have clumped together either with fish juice or ps and they were, perhaps, pulling and it annoyed the eaglet who pulled them out and left a small bloody spot. The eaglet appears to be fine.

You can clearly see the spot on the right wing- and that enormous crop of SE29’s. 30 is eating well. No worries. Lady sometimes feeds it so much that 29 gets itself in a little knot. With the amount of prey coming on the nest there is no need for food competition – and even with feedings spreading a bit, everything should be fine. The eaglets are getting older. Getting ready to get some really itchy pin feathers soon. As long as food continues and Lady keeps up her remarkable feeding schedule..these two are going to grow and fledge.

There will not be any ringing or DNA tests unless one or both wind up in rehab after fledge. But I might be already inclined to guess that we have a really big sister in 29 and a little brother in 30.

We can always use good news in our lives. Here is another story of an eagle rescue that will warm your hearts! Thanks, ‘L’, much appreciated.

Our beautiful Victor. I love this photo of him standing on a low perch. You are progressing, Victor. Keep up the good work!

Since the rescue of Victor, some of us have been more than perplexed about where the zinc came from that poisoned his body. I have rattled my brain with several of you – flakes coming off of anything galvanized, warnings on garden hoses about zinc, the shale in the area contains zinc, etc. I really do not think our dear Victor sat and ate pennies knowingly. ‘C’ sent me the findings of a study by a Brazilian researcher. It has been translated by Google from the Portugese. If you are interested in how Victor might have gotten the zinc and how our contamination of the planet spreads to birds 10,000 miles away even…have a read.

Thank you, ‘C’. Much appreciated.

Title: “Not even the “end of the world” is free from human-caused pollution”

Animals that live in the waters of the Kerguelen archipelago, 3,000 km from the nearest inhabited region, are contaminated by metals such as cadmium and mercury.

Not even the “end of the world” is free from the pollution generated by humanity. Located in the south of the Indian Ocean, 3,300 km from Madagascar, the nearest inhabited region, the Kerguelen archipelago, formed by about 300 islands and islets, is contaminated by metals such as cadmium and mercury, copper and zinc. The observation is made by Brazilian researcher Caio Vinicius Cipro, a postdoctoral fellow at the Oceanographic Institute of the University of São Paulo (IO-USP), in two studies he carried out at the University of La Rochelle, in France, in partnership with scientists there.

Of volcanic origin, Kerguelen is 4 thousand kilometers south of India and 2 thousand kilometers north of Antarctica. The archipelago belongs to that country and is administratively part of the French Southern and Antarctic Lands (TAAF). There is currently a scientific station and structures associated with it. “There is also fishing activity due to France’s exclusive economic exploitation zone”, says Cipro. “Biologically, there are countless species of birds and marine mammals that have established colonies on the island and many others, in addition to significant amounts of fish and invertebrates thanks to the high primary productivity of local food. There are also several species introduced by humans, such as mice and reindeer, and some plants.”

He says that the idea for the study came during a period when he worked as a guest researcher at the University of La Rochelle. “My supervisor at the time, Professor Paco Bustamante, had told me about a dataset he had obtained years before, which he began working on during his own doctorate, and whose publication he never had time to pursue,” he says. “I volunteered to carry out the task and write the publication.”

Cipro then went on to study the occurrence of four chemical elements (cadmium, copper, mercury, zinc and selenium) in more than 30 species of invertebrates and fish, most of them at a lower trophic level (of the food chain). The objective was to understand how the concentrations of these inorganic pollutants behave at these lower levels that will influence organisms above them in the food chain.

Cipro’s first study was carried out in 2014, shortly after he arrived in France, on samples that had been collected by Bustamante’s team in the southern summers of 1997 and 1998. The Brazilian scientist analyzed metal contamination in a species of bird, the black shearwater petrel (Procellaria aequinoctialis). “We found contamination by cadmium, copper, mercury, selenium and zinc”, he says. “An article about the work was published in 2016 in the scientific journal Polar Biology.”

The second research was carried out in 2018 and yielded another article, published in the same journal. “In this case, we analyzed the levels of contamination of the same metals, with the exception of selenium – there were no conditions at the time to do this with this element in the laboratory at the University of La Rochelle – in 18 species of fish and 11 of invertebrates”, explains Cipro . The result of the work also pointed to the contamination of animals by metals.

According to Cipro, what can be concluded from the results of his research is that in this specific case of Kerguelen, cadmium values ​​varied much more than mercury values ​​(four orders of magnitude against one) and depended more on specificity in food ecology. and in the habitat than at the level of the food chain plain and simple.

In other words, the results of the studies showed that, contrary to what happens in most cases, the concentrations of pollutants found in animals depended little on their position in the food chain, but more on specific mechanisms of physiology and exposure, in such a way that predators from lower trophic levels could be more subject to some contaminants than others from higher positions.

This means, according to Cipro, that work with species of higher trophic level or sentinels needs more in-depth food ecology studies before reaching certain conclusions and that the food chain by itself does not mean much in this environment. “Furthermore, my research provides solid foundations on the exposure to which predators are subject, as in most cases this discussion remained on hypothetical terrain due to lack of field data,” he explains.

The work also showed a possible influence of a local secondary source of contaminants, probably the bird colonies themselves, a hypothesis confirmed in the Antarctic environment during his current research project. Going into more detail, Cipro explains that the analyzed metals have natural sources, but human activity certainly plays a bigger role than them in general. For mercury, for example, current emissions are estimated to be three to five times higher than before the industrial age. This element can reach the Kerguelen archipelago from dumps made by factories located 10,000 kilometers away.

Nevertheless, locally, in addition to bird colonies, some other natural sources may be significant, such as certain rocks and fossil fuels. “In the case of bird colonies, some studies that I proposed suggested and later confirmed their role as a local and relevant source of some elements and also of organic pollutants”, says Cipro. “In Kerguelen, we raised this hypothesis, comparing mussels from inside and outside the Gulf of Morbihan, and it seemed to be confirmed by the results obtained.”

The Dad at the Janakkalan Nest, Red CCL, continues to deliver the fish. The chatters have nicknamed the pair. Boris is the oldest and Titi is the youngest. The fish are so big that they take turns with no need to squabble. Titi is on the left. He has not figured out – yet – to hold the fish down with its talons.

Dad arrives with another fish at 1805. Titi is in the back with the huge crop from eating the fish in the image above. Boris is going to claim this one and Titi is absolutely too full to care! Lovely. Thanks, Dad.

The four Black Storklets on the nest of Karl II and Kaia are really wanting a food delivery. While they wait it is raining – they shake off their feathers, flap about, and jump on and off the perch. Kaia arrives with food at 16:58, the last image.

Just look at this beautiful juvenile Red-tail Hawk, L4. Stunning. L2 and L4 will probably be soaring in the thermals soon and leaving the Campus. Every moment with them is special as it is with Big Red and Arthur.

The latest update on L3 from the Cornell Lab:

L3 is gorgeous. Looking forward to her release when she is all healed.

Thank you so much for joining me today. It is wonderful to have such good news in Bird World. To my knowledge, all of the UK Ospreys have fledged. They will be eating and gaining weight as will their mothers for migration. Soon these flights will be charted. In the meantime continue to enjoy them. The same with the storks! Take care everyone. See you soon!
