Tag Archives: St Petersburg FL Osprey nest

Every year we stop and think about the women who gave us life and mentored us to become independent adults. I want to stop for a moment and consider a few of the bird mothers. Last year I was able to single out one bird that seemed to give it her all and that was Big Red, the Red tailed-hawk whose nest is on the Cornell Campus. This year I have a few more to add. I am certain that you have your own list as well.

In studying the social behaviour of birds, one of the things that has astonished me is how complicated the lives of our feathered friends are and how the behaviour of humans has impacted their lives.

The birds are not listed in any particular order – I could not, for the life of me, rank them. They have struggled against the greatest odds sometime. The first bird mentioned does not have a happy ending and this is a warning about that. If you would prefer to skip this mom, then please scroll down to Big Red.

The first female on my list is Milda. Milda is a White-tailed Eagle. She worked with her long time mate, Raimis, and rebuilt their nest near Durbe, Latvia. She laid her eggs on March 12, 15, and 21. The last time that Raimis was seen was the 27th of March. Milda incubated her eggs and stayed on her nest, despite several intruders, for eight days without eating. Then on two occasions, she had to leave the nest to try and find food and was off her eggs for periods nearing five hours at a time. It is not clear how successful she was in hunting. A male WTE appeared and tried to help incubate. By some miracle two of the three eggs hatched on the 21 and 24th of April. The people of Latvia and those who adore Milda were overcome with emotion. But that joy was short lived. It was pretty clear that Milda was almost starving to death. She had completely depleted her bodily resources. The male brought a crow to the nest and the eaglets were fed and then he took it away. It was very cold and Milda had to eat. She had to leave the nest to find food. She was desperate. If she did not survive neither would her eaglets. It is like the instructions when you fly on a plane: put your own oxygen mask on first before you help your children. Did Milda know that her eaglets would freeze? was this a form of euthanasia? did Milda think the male would incubate the eaglets while she found food? In all of this, there was also an intruder. Milda’s eaglets slowly froze to death. Later that day she consumed them.

Cannibalism in eagles is a new area of study with the growing number of streaming cameras. In 2002, a group of wildlife biologists in Virginia were stunned when they observed a male eagle killing his eaglets alive and eating them. More reports of similar behaviour came in leading researchers to believe that the behaviour may be more common that believed particularly in times of food shortage.

Milda was a very devoted and dedicated single mother. The circumstances were dire. She could not help her babies if she could not feed herself and she was starving. We have watched birds mourn their dead. It is beyond my comprehension to understand how difficult all of this was for Milda. The lack of a partner and the inability of a female parent to provide enough food for their eaglet also happened at another nest in Latvia. That was the nest of Spilve whose beautiful eaglet, Klints, perished from starvation. Spilve mourned the death of her Klints. This year, she refused to use the nest that Klints’s body has become a part of. Instead, her and her new mate went to another.

I am really aware of the dedication that the Latvians have for their wildlife. What has caused a drop in prey? has it always been this difficult? and would it be possible to stock artificial ponds for these large raptors? Those are just three of my questions.

My second bird mother of the year will always be first in my heart- Big Red whose territory is on the Cornell Campus.

Big Red hatched near Brooktondale, New York in 2003. She was banded on 20 October 2003 in Brooktondale. She is eighteen years old. The exact history of her mates and the number of eyasses she has raised to fledge will never be known. She was known to have a nest in 2010 on the Cornell Campus and two years later cameras were installed. Her mate at the time was Ezra. Ezra was killed in 2017. It is the only year that she did not have a clutch. She bonded with her current mate, Arthur, that same year. It is entirely possible that Big Red has fledged no less than 35 eyasses. This year she has another clutch of three. Big Red is a devoted mother. By the fall she is already selecting which light tower to use as a nest and is working with Arthur then and to a greater degree in February to ready the nest for the upcoming breeding season. She has been encrusted in snow more times than I want to remember and soaked to the bones. She has been blown off the nest! Still she works and keeps those kiddos of hers full to the brim. As someone recently said, ‘No one leaves Big Red’s table hungry.’ And when her eyasses fledge she will spend days with them in family hunting expeditions so that they are as prepared as she can make them for the outside world.

Today, she was soaked to the bone and cold – even the babies are a wee bit ‘wet’. Those heavy raindrops wanted nothing more than to turn into icy slush. She fed her three little ones as quickly as she could so they would not get wet and catch a chill. Just look at the love in those eyes! Being a mom is what it is all about for Big Red.

Unlike Milda, Big Red has a devoted mate, Arthur, who is busy filling the pantry providing food for Big Red and the Ks as well as security for the territory. Arthur also gives Big Red much needed relief breaks despite the fact that she prefers to look after the little ones almost 100% of the time! Her territory is also prey plentiful.

Big Red will always be at the top of my list. She is just simply amazing.

My third female is Diane at the Achieva Osprey Nest in St Petersburg, Florida. I am including Diane in my list for one single reason. This year her three eggs hatched and she had three osplets to raise. At the time the three were born (5th and 7th of March), there was plenty of prey on the nest. However, a week later the fish deliveries became irregular causing food insecurity on the nest. It was unclear whether or not the third hatch would survive. There would be days of plenty and then hardly any fish. If the babies didn’t eat neither did Diane. Many suspected that Jack, her mate, might have another nest. Diane began to go fishing supplementing the fish that were brought onto the nest and that is why I am including her. When she was able she would leave the nest and bring in huge catfish to feed her babies and herself. She was a selfless mom. The two older siblings and in particular, the second hatch, demanded more and more food. For days in a row the third hatch had no food. Even Diane acted on several occasions like the little one would not live. Then something happened. The food became more plentiful and she paid particular attention so that the third hatch was full. I call him Tiny Tot. This year Diane will fledge three – . Tiny Tot is the only one left to fledge and his feather growth is behind. And that is OK. Tiny Tot is simply a delight.

In the image below Tiny Tot sits in the middle of the nest with its full crop and its ever growing wings. At one time no one believed #3 would survive and most thought it would be stunted but Tiny is filling out all over. Diane makes sure that sibling #2 standing on the rim of the nest at the back does not eat all of the fish that comes on the nest. I have to give her like 5 gold stars for stepping in and making sure that the food is shared between these two. No one is left out.

Diane is on the nest with Tiny. They are both waiting for an incoming fish.

Tiny Tot can self-feed. He was the first of the three to do so. To survive he found fish bones with a little flesh on them and ate it. Diane does love to feed him, tho.

As the sun goes down, Diane and her two little ones are full. Tiny is actually full to the brim. You can see that glimmer of the sun on his big crop.

Another bird mom that has touched my heart in a way that I cannot quite put my finger on is Eve, the mate of Eerik, whose nest is in the Matsalu National Park in Estonia. It is so cold in Estonia that the geese had to stop their northern migration. Eve is a huge White-tailed Eagle – she almost looks ‘wooly’ because her plumage is so thick to keep her warm. She is the most gentle of mothers with her two little eaglets.

Eve does not have the prey problem that Milda had in Latvia. There are plenty of fish and other birds that Eerik brings to the nest. Eve carefully conceals them and keeps them fresh in the straw around the rim of the nest-like an old fashioned ‘ice box’. What they have had to contend with are intruders and lingering cold weather to the extreme. It is especially important because the eaglets cannot thermoregulate their temperature. They depend on Eve and Eerik for everything. Many mornings Eve has woken up to be completely covered in a cold frost. I am really looking forward to these two growing up. Look at the little one put its wing around its big sib. This is such a peaceful nest. Eve keeps everything under control.

There are so many bird mothers whose lives need celebrating if for nothing else than they successfully raised their clutches. It is not easy. Humans have impacted their lives in so many ways it would take an entire blog to list them but climate change and its impact on prey, loss of habitat, plastic in the oceans, toxins, etc come to the top. I cannot even begin to create a list of all of those. If I continued to include images and write ups for the mothers, the blog could easily include Harriet at the Bald Eagle Nest in SW Florida in Fort Myers. She is just an amazing mother to E17 and E18. Those kiddos are well equipped to take on the world. Then there is Anna, the first time Bald Eagle mother, who had to learn along with her eaglet how to feed her baby properly. Kisatchie has thrived and is now branching on his nest tree in the Kisatchie National Forest. On the Mississippi River, the nest of Starr and the Valors was destroyed last year by the winds. Starr had to work with Valor I and II to build a new nest for the 2021 season. They built an amazing nest and now have three growing eaglets. Or what about the female at Duke Farms who spent the entire incubation period encased in snow? Her two eaglets are now branching. Diamond, the Peregrine Falcon, in Orange, Australia still has her seven month old fledgling living in her scrape box. Her patience is amazing and her and Xavier have raised a formidable falcon! What about the Osprey females who lay eggs and raise their little ones in nests so full of toys and blankets they often cannot even find the chicks. This year, Harriet at the Dahlgren Nest, lost one of her eggs in Jack’s deliveries! They probably deserve a medal every day for their good humour. Then there are the ones, driven by their instincts and ‘Mother Nature’ that want to be mothers so badly such as Jackie at Big Bear or Iris at Hellsgate? If certificates were given out, they would all receive them – every single one of them!

Here is Iris bringing in a whopper of a breakfish for herself. Iris is the oldest living osprey in the world – the grand dame of all Ospreys. She has fledged no less than 35-40 osplets – no one really knows for sure, that is just an estimate. Since the death of her trusted mate, Stanley, Iris has returned to her nest every year during breeding season. Her current mate, Louis, has another nest and another mate and Iris is now, by default, a single mother. Her natural instincts bring her back from her 4,000 mile migration to her nest in Missoula, breeding with Louis, and because she is both provider, incubator, and security guard – like Milda and Spilve – her clutches have not been successful. Her last fledge was a single osplet in 2018. Still she is there doing her best!

And Happy Mother’s Day to Maya on the Rutland Mantou Nest whose first osprey egg of the season hatched at 15:23 today, 8 May. You can just see the little one getting out of its shell.

Thank you for joining me today to appreciate the difficult circumstances each of our bird mothers face. There is a story for each of them! They are all much loved.
