Thursday in Bird World

20 February 2025

Good Morning Everyone,

Thank you for being with us today. Many of you are experiencing cold, wintry weather, and I understand that those of you in the southeastern United States are particularly surprised by the chill! While we should be accustomed to the cold here, I must admit that I wish it would go away. We haven’t been able to spend as much time outdoors as we would like. We all need to engage with nature. It is so good for our mental health. Please be careful if it is snowy and there is ice. Nothing is important enough to fall and get injured.

While our friends in the UK hope spring might be just around the corner, we are still in an extreme cold warning on the Canadian Prairies. It is one of the most extended extreme cold spells I can remember in recent history. Thankfully, the triple pane windows also create heat, and ‘The Girls’ can pretend they are outside in the sun. Even the sun warms up the conservatory for about six hours, and then, as the sun begins to lower itself in the west, the cold sets in. They have to come into the main part of the house and not one of the four is happy about that. They love that glass box where it is like they are living outside, but are actually safe inside.

In this extreme cold, I am always fretting about the outdoor animals. One Crow has consistently come to the table feeder to eat nuts from the cylinder. You can see the sparrows all puffed up to keep warm. They love perching on the branches of the lilacs and getting warmth from the sunshine. They will leave the garden early as soon as they begin to go down. By 4:30 things are pretty quiet. I am, however, missing all the beautiful birdsong from the garden. The number of songbirds is in significant decline.

I am so glad that Calico and her kitten Baby Hope are inside and not out with Brock and Star. There appears to be nothing I can do to convince either of them to trust me despite Brock now sitting about 15 cm or 6 inches from me when I take out food. If there is any sudden movement, he is off. I do not want to stress them out, but something will be done come spring – it will be an enclosure with a heat lamp. (Right now, it is too much work and cold to begin dismantling the wood boxes…I wish I had done it earlier.) If Star has kittens, which I fear she might, we will trap them and make sure they have homes.

The mailbox brings me to the topic for this post: Darvic rings. A reader wrote, “I was wondering if you’d heard anything about the banding of the osprey at Abu Dhabi. I saw them being weighed, but they didn’t measure their wings. Yet they put blue bands on one of all of their legs. They put a silver band on the other leg of all of them too. Wouldn’t the blue band be for boys? Why put a blue band on at all?”

Heidi did the video of the ringing of the triplets and I post it again here. https://youtu.be/ki2xKtFBF_Y?

What are Darvic Rings? The Darvic rings are a plastic ring that is fitted to the Osprey’s leg. Normally you can see them from a distance with binoculars or a spotting scope. Different countries use different colours. In the United Kingdom, the bands are blue with white lettering. Scotland places the Darvic ring on the left leg while England and Wales put it on the right. In Spain the Darvic rings are yellow, in Germany they are Black, and in France they are orange. Over time the amount of numbers or letters has changed but there are registries of every bird that is ringed. 

The birds are also fitted with a metal ring. It has a unique number and address and is more durable than the plastic ones which can, after several years, break. 

Birds are ringed before they are 45 days old. The reason for this is so the specially trained banders do not frighten the birds and cause them to fledge prematurely. Also, the leg will have grown to its adult size. This prevents the ring from getting too tight and injuring the bird. Ringing often takes place when the Osprey chicks are in the 30s – such as 36 days old, etc. At the time of banding the chicks are weighed and measured. Indeed, everything about them is measured!

So for the United Arab Emirates where the Abu Dhabi nest is located this is the specific information on ring colour and placement.  Nothing to do with gender:

Title	Colour-ring type	Soort	Colour-ring colour	Colour-ring code	First letter	Last letter	Colour-ring position
Ospreys	Legring : one, coded.	Osprey	Dark Blue [B]	Three alpha-numeric code (3 letters/numbers).	E		Tarsus right.

 There are online lists of the colours of the rings for each country. If you spot a bird with a Darvic ring, there are sites where you should submit that information. It is always good to be able to locate where the birds are and if they are alive.

Few ring the ospreys (or other raptors) in North America which is a real shame. The benefits of ringing the birds – whether they be a raptor or a songbird – are many. Here are only a few articles to help you understand why this process is important.

Checking on some of the nests:

Kistachie National Forest E3: The eaglets are getting frisky and playful. https://youtu.be/yUWLzSliOAA?

Redding Eagles: Will the heat impact any late eggs laid? https://youtu.be/yUWLzSliOAA?

Captiva Eagle Cam: Dasher and Dancer are doing just fine.

Achieva Credit Union Osprey Platforms: No egg yet for Jack and his new mate. The chicks normally hatched the first week in March. It is getting late for a clutch. I worry about the heat of the summer just as I would if there was another clutch at SW Florida.

NCTC: Scout is getting into the action of incubation. Fingers crossed. The couple now have three eggs! https://youtu.be/SsMcuXsNUIE?

Big Bear: Could you ignore Shadow’s charms? https://youtu.be/1ZAaKfrNXoE?

West End: In case you missed it, the first egg of Thunder and Makaio was taken by an opportunistic Raven. https://youtu.be/202j3SgZOwA?

Hilton Head: The two eaglets are doing well!

PA Country Farm: The male, Oliver, is showing signs of having HPAI. Please send your good wishes.

Little Miami Conservancy: The first egg is laid for eagle couple, Bette and Baxter, on Wednesday.

USS Steel: There is a three egg clutch for Irvine and his new mate, Stella, in 2025. She is a young mum, but Irv knows the ropes. It should be an exciting nest to watch this year. https://youtu.be/2mMml-j86cA?

Cornell Red Tail Hawk: Both Big Red and Arthur have been spotted on campus.

Moorings Park: Sally and Harry continue to incubate their three eggs.

Pine Island Ospreys:

Johnson City-ETSU: Eggs on January 23 and 26. Boone and Jolene should be expecting a pip by the end of February! Just think – 8 days.

Royal Albatross Colony: Adorable chick nestles next to its mother. https://youtu.be/Baq1kDo8k7Y?

SW Florida: M15 and F23 come to the nest. https://youtu.be/wFSLKTEhqq4?

NE Florida: For a $5 donation, you can help select one of four names for Beau and Gabby’s only eaglet in 2025.

Dale Hollow: Taylor and Franklin have their first egg.

Friends of South Australia Ospreys are concerned about Marie from Gleesons who has flown far from her nest.

News of new nest platforms comes from Geemeff:

New nest platforms in Utah:

And in the Bronx:

New home for osprey birds being built in Eastchester Bay

There is also a new platform at Granville Island in Vancouver for eagles. It is a galvanized pole erected by one of my former students who was in charge of the rebuilding of the Market area. More information to follow.

There is a new FaceBook group organized by Trudi Kron for the Wolf Bay Osprey platform in Alabama. Here is the link to the group: https://www.facebook.com/groups/1368435824519762

Here is the link for the camera. Sticks are already being delivered! https://youtu.be/3xUG9gpVzlY?

Wildlife is truly under threat. Many of the nature centres and rehabilitation clinics are going to need your support and help. This is one of the latest postings.

Geemeff asks, “Stating the bleeding obvious- pesticides kill! Did we learn nothing from Rachel Carson? Silent Spring was written more than seventy years ago and sadly, not much has changed, if anything, things have got worse.” I agree. Humans have much to clean up and wildlife needs us more now than ever.

One of our next conversations is going to be about where your donation dollars do the most good. Many are abandoning the WWF because of this – and other large organizations where the staff take more of the donations than the wildlife!

.They are not birds, but at this stage, the balance and health of all wildlife has to be of our concern. That includes those adorable little European hedgehogs that populate the gardens. They were of least concern and now their existence is ‘threatened’. Habitat loss and pesticide use. It is a mantra that we are going to hear over and over again this year as animals die because of us. Please help them. No more green beautiful Home and Gardens lawns. Plant for pollinators without using pesticides. Urge your neighbours, your family, and your friends. ——– It looks like it is going to be up to use to take care of the areas around where we live. Imagine the power of the people of the world if we each dedicated our lives to making their lives better. Imagine.

I feel blessed to have so many talented and caring readers, many who are have become friends over the years. One is Juni Li, a New York artist, who has shared a drawing of Iris and Finnegan with us. Just imagine—within six weeks, Iris could be back with us. Wonder who will arrive first: Iris or Finnegan? Wish them good health, favorable winds, bountiful crops – and no interlopers.

I so wish Sum-eh and Antali had been ringed. Without Darvic rings, we will never know them if they return or if someone sees them in another area. We will also not know if they are found dead.

Iris always makes us smile and I hope this next story, sent to us by EJ, will, too.

The Northern Ireland Raptor Study Group Conference is fast approaching. Hopefully they will provide us with archival talks and paper presentations.

Thank you so much for being with us today. Take care. We will see you again on Monday!

Calico is such an intelligent cat, and she is working hard to figure out the best way to provide help for feral cats. I wonder if she remembers living in the cold. She has created a line of five blank note cards on premium card stock with envelopes using my images. Her goal is to sell 500 cards. We have decided to do this directly instead of selling them through shops (who take multiple percentages from 40-60). It will mean more work for all The Girls and us, but in the end, those funds will provide much-needed food and help with spaying and neutering within our community.

I will post a separate page with information on how you can help Calico meet her goal on Monday!
