Tropical Storms, Hurricanes, rising water temperatures all impact our beloved birds

Is there anyone who is not aware of extreme heat that is in the Pacific Northwest? or the fact that the rivers and creeks are drying up? and the temperature of the water is getting hotter?

The Montana Osprey Project has just posted the following:

“In order to reduce the stress and disturbance on these fish, Montana Fish, Wildlife and Parks has placed fishing restrictions on many rivers in Montana, including parts of the Clark Fork River, Big Hole River, Gallatin River, Madison River, Beaverhead River, Jefferson River, Ruby River and others. The trout populations in parts of the Clark Fork River (and other rivers) have dropped to fractions of their former sizes. The low water and warming temperatures are suspected to play a big role in these population declines.”

The river temperatures in Montana are at 75 degrees F. The authors of the FB Montana Osprey Project posting state that they will “not immediately kill the trout” but a long exposure could kill up to 50% of the fish. That is why they took such drastic actions. Those warm waters impact all the fish that the Ospreys consume including the grand dame, Iris. The authors say that they will follow up with a report on what they believe declining fish numbers due to heat will have on the Osprey populations.

There has been much discussion about the impact of weather systems on our birds and all of us are watching Elsa. My inbox has been full of queries – for which I am very grateful. It shows the love and concern we all have for these gorgeous fish hawks (and the other birds).

I wanted to find out what had happened to the birds on the island in the Caribbean where my son lives – Grenada. The year before he moved to Grenada, 2004, there were two hurricanes that hit the island directly, Ivan and Emily. Each struck the island. Ivan was slow and deadly churning over the islands of the Atlantic for twenty-three days. Ivan was enormous sustaining winds of 165 mph or 270 kph. It was the strongest hurricane of the 2004 season and destroyed the growing economy of Grenada. The palm trees lining one of the most beautiful beaches in the world with its pure white sand, Grand Anse, were uprooted. Most houses lost their roofs. An old timer told me that they called the hurricane ‘Ivan Rufus’. People were in their houses and the roofs went spinning off. Centuries old nutmeg trees were destroyed along with much of the bird populations and their source of food. The worst hit were the birds that feed on nectar, fruit, and seeds. Nests in the forest were destroyed and breeding was delayed.

There is a really good article that my son sent me today that is called, “The effects of hurricanes on birds, with special reference to Caribbean Islands” by J.W. Wiley and J. M. Wunderle. It was printed in Bird Conservation International. While the article does deal with the Caribbean, it brings much insight to what could happen along the US Southern Coast.

Elsa is predicted to stay as a Tropical Storm so, as you do read the pages, please keep that in mind. There is nothing pointing to Elsa gaining strength to become a hurricane. Tiny Tot should weather the storm fine. She will be soaked and that nest could be missing some twigs but it should also have been built using hurricane standard methods. Still, all of us will keep watch and send warm wishes that all of the birds and wildlife are not impacted.

I am attaching the article here if any of you are interested. The same information could be applied to areas hit by hurricanes in the US.

At 4:55:17, Jack delivered Tiny Tot a really nice fish! Thank you, dad.

It looks like Mrs G gave up on Aran and went and got her own fish today!

At the Lyn Clywedog Nest, Seren has decided for their great Big Bob to see if he can begin self feeding. That is a really nice fish that Dylan brought in. Like all moms, Seren will give in and help Only Bob but he is giving it a good go before asking for help.

There is an easy way to deal with the rising temperatures, the droughts, and the declining fish stocks for the birds that rely solely on fish stocks for food. The first is for humans to take responsibility for climate change. Then build fish farms for these birds – not for humans, for the birds. When the Ospreys migrate to places in the northern part of South America, such as Columbia, they are often shot for stealing from the farms. So we know that they will get fish out of tanks – so build them if they are needed and put some enthusiasm behind the word ‘Conservation’.

That’s it for a hot Sunday in Canada. I do not know where the birds are that generally hang out in my garden but they are still not arriving and it is nearly 7pm. There is lots of water and food. Hopefully they will come soon.

Take care everyone. Thanks for joining me. Continue to monitor Elsa as she moves towards Florida. Stay safe Tiny Tot!

Happy Saturday in Bird World

It might be hot and windy but Jack has delivered one big fish and another piece onto the Achieva Osprey nest this morning. Thank you, Jack! All is well on that nest! Tiny Tot still had his crop from yesterdays big feed when a big fish arrived at 7:16:50. Despite the fact that he was right there when that whopper landed, Diane pulled the fish around to feed the bigger ones first. She knows what she is doing. Feeding them first kept peace on the nest and she knew there would be enough left for her and Tiny.

Tiny Tot remained in his position when the fish arrived while the older sibs ate their breakfast. Without calling attention to himself, he pivots so that he can eat when they are finished. Very smart.

Tiny Tot is a survivor. He is clever and he keeps his eye on everything that is going on in the nest. Today, there have been no attacks on him. Did the arrival of all that fish yesterday help calm the food competition on the nest?

Tiny eats! At 9:20:03 Tiny Tot looks like he has swallowed a beach ball! Look at that crop. I just think this is the silliest pose I have ever seen in a bird. Tiny is preening his tail.

In the image below you can also get an idea of how much bigger the older sibling is than Tiny. Look at the difference in their wings. Tiny is getting his juvenile feathering on his back and wings. For sure, a total of about 7 full days without food (if you add it all up) stunted his growth. Let’s hope that these good feedings help him get bigger quicker.

Jack is working on more gold stars today. Everyone is looking up as the second food item arrives at 11:10:22. It is hard to tell but it looks like a piece of fish not a whole fish. Once again our little trooper is jolly on the spot.

This time Diane did not move the fish. She kept it by Tiny Tot and started feeding him immediately. The older ones were watching the traffic together.

At some point the older siblings came over to get a few bites. There was no bonking. Tiny had eaten a lot and he quietly turned to the rim of the nest. When they left, he turned back to mom to eat some more. Diane also ate some very good bites but before she finished the last bit, she stretched her neck to Tiny who, at first, refused any more food. In the end, he did eat a little more at 11:46:44 after mom insisting. Here he is full, Diane tidying up the tail, and a very happy nest on a hot, very windy day in St Pete’s.

In other Osprey news, Mrs G has laid her first egg of the 2021 season! Mrs G is the oldest Osprey in the United Kingdom and is the mate of the unringed male known as Aran at the Glaslyn nest in Wales. Congratulations!

And poor Dylan. The weather in the United Kingdom has been strange. It snowed on the Clywedog nest in Wales on the afternoon of 10 April. Here is that beautiful Dylan posing for us.

The mystery at the Loch Arkaig nest continues. Everyone believed that Louis had arrived the other day but it looks like it was a male intruder who is still hanging around the nest. As far as anyone knows, Louis and Aila have not returned. (I erroneously reported Louis had arrived as did everyone else!) The weather and the winds continue to be an issue and this very popular Osprey couple could be waiting it out. Meanwhile, the nice looking male looks like he owns the place.

I really wish Louis and Aila had trackers so we knew they are alright and just progressing slowly. In the satellite image below, we can see Rutland 4K (13) making his way through France on his return trip from Africa. In this 250 kilometre or 155 mile section, Rutland 4K (13) reached heights of 650 metres or 2132 feet above sea level.

These advanced backpack transmitters are amazing. They can tell you where the raptor went for their migration and if they are near to any dangerous issues such as Avian Pox along the coast of Senegal in 2021. They tell us their travel speed, the height, where they are enroute during migration. Researchers can then match this data with wind thermals. We are learning so much!

This is the most recent tracking data on Solly, the female osprey from the Port Lincoln Osprey nest. Solly is 203 days old today and she spent the night up at Eba Anchorage. Ever since she left her natal nest on the barge at Port Lincoln, Solly has been traveling north but she has continually returned, if she went much beyond Perlubie, to either Streaky Bay or Eba Anchorage. Solly has already provided the researchers in Australia with a dirth of material. We know where she spends the night, where she goes to fish, how she responds to crowds on a beach and how far away from her natal nest she went – which changed our understanding of the distance juveniles travel when they leave home.

Switching over to the United States again, it is a beautiful sunny day in Ithaca, New York and our favourite male Red-tail Hawk has been on incubation duty. In fact it is 23 degrees C and no snow in sight! Arthur, you really are a cutie. Look at that gorgeous red tail. Big Red seems to be trusting you more with nest duties.

The little eaglets born on the Minnesota DNR nest are growing. The eldest stretches its neck and watches Nancy, the female, eat the fish tail. Look at that little crop. This nest is doing really well. Everyone has learned how to feed or eat and the supply of food seems just right.

It is a good day just to pop in and check on those Great Horn Owlets, Tiger and Lily. Here is Tiger this morning standing next to Bonnie. How is that for growth? The time passed so quickly from the day the pair of owls decided to take over this Bald Eagle nest for their owlets. That was 1 February. The owlets were born on 7 and 9 March and are now 33 and 31 days old. We will see them climbing all over the nest and upon the branches soon. In a little over two weeks, around 47 days old, the owlets should be trying to fly. That should be around 24-26th of April. They will stay around the nest, improving their flying and hunting skills before dispersing to their own territory.

Thank you so much for joining me today. I hope that your Saturday is as beautiful as it is here on the Canadian prairie – gorgeous blue sky and no wind. Looking forward to 14 Celsius about the time for my walk. Take care everyone. Enjoy your weekend.
