Distressing issue….
I have so many stories to tell, so many experiences to share…I can never get around to them all. Here is one more for you. This is a nest that popped up this year on a power pole near a big power plant. In those early days of watching them I thought….my that female has such unusual markings…..such a dark face. And then her mate landed next to her and I thought, how odd….he has very dark markings too! Then suddenly my brain exploded and I understood….this power plant processes coal. This birds are covered in coal dust. I was horrified. If this is what their faces look like, what is happening to their lungs? This coal dust does not wash off in the rain or when they bathe. I have been deeply worried about the two chicks…..but I am relieved to report that they both fledged successfully. So I am hoping they will begin to spend time further away from the coal piles, in safer surroundings. The chicks don’t look as bad as the adults. I hope the power plant removes this nest and this pair will find a better place to nest next year….tho I won’t recognize them probably!
Missing old friend….
I had a very exciting morning today….there is a lovely banded male who nested on a cell tower for the past five years, and sadly his nest was removed and the tower was altered so he could not rebuild there this year. I searched for him and found him a short distance away in other cell tower. He and his mate were there dropping a few sticks. When I visited again, no real progress had been made and the female was gone. I watched the male just sitting there. The next time I visited, there were no ospreys at all. I searched for him at least three times this summer to no avail. I was very fond of this banded male….he also has a brother who is nesting about 8-10 miles away. I knew he had to be around and I also know that ospreys are very philopatric….loyal to their nesting territories. As I headed out this morning I thought, I will do one more search, extending a bit further south. I checked cell towers, transmission towers, a previous nest site of his…and found nothing. I went back to the cell tower where I last saw him…no one there. As I was driving away I saw an osprey flying across the road with a stick….I quickly turned around and got myself focused on the cell tower as he landed….IT WAS HIM! I was so happy! He is alone, but now he is doing some work on building a nest on that cell tower. I don’t know why he didn’t do it earlier….but I wonder if they nested somewhere else and failed. I just don’t know….but finding him again made me very happy. I will recheck to see how the nest is going and I hope his female comes back too. He is a great parent who has fledged chicks every year except this one. It’s funny how attached you can get to these banded birds when you watch them year after year. Gosh, that made my day….
Confirming successful fledging….
Crazy busy weekend….frantically trying to gather data on successful fledging….that means visiting nests and watching for a while to try to account for all chicks right after fledge. It’s not easy, it can be time consuming. Many people don’t understand the value of this info….it determines if a nest is successful or not, it also determines the number of chicks that we record for the overall totals. My mentor, Sergej Postupalsky, wrote a paper about terms and methodology that is still very much a guiding light for me. It’s important that we discern the various causes for failure and what constitutes success. I had a boss that wanted us to consider the number of chicks we banded at 4.5-5 weeks of age as the final number. Sergej strongly disagreed with that since at that age the chicks are only about half way thru their development….and many won’t fledge until they are close to 8 weeks old. There are a lot of losses in those weeks, so an earlier number is falsely exaggerated, and slants the data. So I try very hard to get a number of chicks right before fledging age….and then confirm the number of chicks that we know fledged successfully. That does not mean they flew away….since osprey chicks are dependent upon their parents for food for several weeks or a month post fledge. So we are looking for chicks that have flown, landed safely somewhere and are returning to the nest to be fed. This is not easy. I am working very, VERY hard to get this data. Sometimes I just don’t get back soon enough after fledge to find them all and see that they are being fed. With well over 200 nests now, it’s becoming an impossible task without more help.

What a beauty….
After the rain today I did step out to visit a few nests…

The new male returned….
Yet another interesting day where I don’t get as much done as I planned. I stopped at the single females nest…..no one was there. No one was perched in any of the usual places. I heard nothing, I searched and waited for an hour…..starting to get worried. Then as I was about to leave I saw an osprey on a water tower nearby…..I scope it and it was that handsome new male, eating a fish. Suddenly he chirps and flies towards the nest….but another osprey was flying towards the nest too and they both had a fish. They both landed…..it was Mom and the new male. But no chick. They stood there next to each other….no aggression….and then the male went off to a light pole nearby. Mom waited, looked in all directions…..she did not eat her fish. She kept looking for her daughter. After a few minutes she flew off with the fish towards the lake across the street. She flew a loop and then headed back to the nest, followed be her screaming offspring! She rounded up the kid. Then she started feeding the chick….but before long the chick said, I can do it myself and grabbed the fish from mom. Mom said OK. The chick ate. Mom watched. Then the male came to the nest with his fish! He dropped it and left. The chick looked at it and thought it was a better fish, or at least a bigger fish, and dropped the one she was eating and grabbed the one the male dropped. Then mom took the remains of the chicks fish and they both ate. Wow. So this wonderful new male is still around. He is bringing the fish to the Mom as a courtship offering. But the chick is benefiting. This is only the second time I have seen him, but that means he wasn t just passing thru….he is hanging around. He is a good hunter and always has a large fish. There is no aggression between him and the female. I am feeling kind of hopeful…..that they may be establishing the beginning of some sort of bond, and that if they both survive migration, maybe next year she will have a real mate. If this new male begins to think of this as his territory, he may be willing to fight off the polygynous male down the road. It’s still tenuous….but seeing him bring a fish for the second time certainly is a good sign. And little miss muffet is also doing well. Boy that was fun to watch

Parental care….
I have been SO busy that I have been saving up a bunch of posts that I wanted to share with you all. These days, when chicks are fledging, are among the most important and I have to devote myself to watching them and gathering the data before we run out of time. So answering emails and writing posts have sort of taken a back seat….and I am working long hours during super hot weather….and well, one person can only do so much. So my focus has been on fieldwork, collecting the data.
Fledge at the Arb!
The first Arb chick fledged today! At a little after 8 am she took off….first photo….and she returned at about 10:47….i think at first she tried to land on the camera cause mom and the remaining chick were looking up and the whole camera shook. But then she tried again and landed in the middle of the nest between the other chick and mom. Boom! Successful fledge! Thanks to Meg for alerting me as I was out in the field….but I had been seeing the signs of imminent fledging for a few days so had her alerted. I cant sit in front of a screen that much…and I watched all morning before I had to hit to road to check many other nests….so there ya go folks…..one more to go! Any day now! But now we have to tell them apart…..

All present and accounted for!
I was out the door again before 6 am….and checked some different nests on my way back to the one where two chicks fledged and disappeared yesterday. When I first arrived

Trials and tribulations….
Another 12 hour day in the field. I left home at 5:45 to check a bunch of nests for fledging before it got too hot. That was the plan anyway. I had heard from one of the monitors that her nest had a chick doing a lot of flapping and getting some loft. I know that usually means they might fledge in a day or two. She was unable to revisit today, so I went to check on those chicks. I stopped at a few other nests along the way.

An important fledge!
So much has happened this week….I think I will start with today tho…..SO much fledging going on. I went to check on the single mom and her chick yesterday. It’s a female chick and she has been laying low a lot , but yesterday while I was talking to someone she got up and hovered above the nest!!!! Mom came flying back to the nest and the chick settled down. So I headed straight over there this morning and yes our little darling fledged…..flying some beautiful loops, solid landings, always returning to the nest. Mom was perched outside the nest to give her plenty of room for takes offs and landings. So once again this amazing female has pulled off fledging a chick all alone. The sad part is that that magnificent male that I watched bring a huge fish, and hang out on the nest the entire time mom was feeding the chick….has not returned. I have been there several times and so has the monitor, Vicky, and we have not seen him. I will keep hoping for her to attract a great mate who will take good care of her in the future. Maybe that gentleman has his foot in the door….
Meanwhile, this chick has made it to an important milestone and I am gonna celebrate tonight!Sunday, July 19, 2026
New male????
Well, each day is more interesting than the last! This morning I headed out to check on the single female who is raising the chick alone….with the polygynous banded male only showing up occasionally. I first stopped at his main nest, where there is a female and one chick. As I arrived in the area, I saw an osprey fishing in the lake and I stopped and grabbed my binos to look and it was the female! Hmmmmm. I went to the nest and the chick was alone, and the female arrived very quickly with a large bullhead. Where is the male? So I ran down the road to the other nest and found the female with her chick. I was taking some photos when she started food begging. A male flew in and dropped the tail end of a small fish….hardly a meal….and immediately flew off. Was that the banded polygynous male? I dont know. Mom ate a few bites and then let the chick have it to finish. It was gone in no time. Everything was quiet for a while….and then mom started food begging again, much louder and more insistent. I looked around and saw a male with a BIG fish eating on a light pole a short distance away so I zeroed in on him with my scope….oh my….it was an unbanded male! NOT the polygynous banded male. The female kept hollering and he just kept eating….but he would stop and look over the the female and chick. And then he pooped and that often signals an osprey about to take flight so I got the scope back on the nest, got my phone up to the scope and he came and delivered the fish!!!! Mom grabbed it aggressively and immediately turned her back and mantled over the fish….defensive, and with her back turned to the male she fed the chick…..for a LONG time. And the male remained on the nest the whole time. She did not shoo him away. I took a lot of pictures so I could document his dorsal feather pattern for future identification. When the fish was gone….the chick turned and started to walk over towards him and he flew off. Didn’t want to have anything to do with the chick….he knows it’s not his. But he may have decided to help this damsel in distress as a way to secure this territory for next year. He is a handsome fella. And a generous osprey….and I will also say, a smart osprey. So I had seen a male perched very far away on a water tower a few weeks ago, and that may have been him….and somehow he has worked his way in to her life. Me and the other monitor on this nest have not seen anything like this before tho….and I don’t know if the first male who dropped the tiny fish was him or the banded male. Aint osprey life interesting? I just want to be there all the time now, watching to see how often he is there. Did something happen to the other male to allow this opening? The other female was fishing for her chick today. I have so many questions….but it’s definitely a positive development! Here are a bunch of photos!

My reward….and a thanks
I had a fun morning…..this past ten days have been a struggle with the heat, smoke and so many nests….and today was my reward. The ospreys always do reward people who watch them a lot. I got up at 4:30 am to head out to check nests before it becomes too unpleasant….I had a long drive this morning but got to the first nest about 6:30 am. I hiked out to the nest in a beautiful park….no other people around. So quiet and peaceful. I got to the nest and immediately saw two chicks standing up, and Mom on the upper perch. I set up the scope and could see the third chick laying low in the nest. One chick began hopping and flapping…..and I thought, oh, this one might fledge this weekend. As I continued to watch and this chick was really working hard, flying from one side of the nest to the other. The other chick layed down too to stay out of the way….and I thought, I can’t leave, this one may fledge any minute! Then he stopped and stood on the edge of the nest for a while looking around, thinking….and then off he went! Flying loops all around the area. Of course I didn’t have my phone up to the scope when he did take off and I first I just kept my eyes on him. As I teach the monitors..if they fledge don’t take your eyes off the chick until it lands somewhere! And I keep watching, my heart racing….and as he headed back to the nest I quickly got my phone up as the other two chicks stood up to watch….and I got his landing! I was jumping up and down and yelling woo hoo! There wasn’t anyone around to tell!
It was so much fun to watch and for him to make it back to the nest made it a successful fledge. This is a very fun nest to watch and I have to also acknowledge one of the people who made this possible. This nest is a very old pole that was put up way back in the early days of the reintroduction…but it was never used. So after some discussions about why, Larry, a seasonal employee at this park, cleared away all the trees that had grown up around the Nestpole and he filled the nestbox with sticks, added a big perch for the adults…and then voila, we had ospreys there! The first year it was a male with a silver banded female who turned out to be too young to breed, so they were just housekeepers the first year. The following year she returned but she was displaced by another female. So…..that silver banded female moved and she is the one you all have heard about who is the single mom raising a chick alone after mating with a polygynous male. Anyway, these two unbanded ospreys have now been there for six years and have successfully fledged three chicks every year!!! SO thanks to Larry for all his efforts!

Smoke…..
Things started to feel apocalyptic this morning! In addition to this horrible heat wave, we were stewing in a thick smoke from the wildfires up north. I had an early medical appmt and then I just had to recheck a couple of nests. I returned to the nest where one chick had fledged yesterday, and found all three had fledged. Both parents, the 19 year olds, were close by…the male perched in a tree near a fledged chick who went to the same tree that yesterday’s fledge landed on. And another chick was flying around, flapping too much, disappearing behind trees and he finally returned to the nest and picked up a fish and ate. I tried to keep my eyes on all of them, but I did not see three chicks at once. I waited for 90 minutes, but the smoke and heat were too much for me. I got a few photos of the last chick to fledge, and the other one eating and Dad in a tree. Terrible photos, but that’s what it looked like….gray, smoky, weird.

More fledging!
Another stinkin hot day….mid 90s, hi dewpoint. But I went out again before 7 …..I visited a lot of nests, and found a few more chicks that have fledged! One of the nests I visited is the one with two 19 year old adults and three chicks. I discovered one chick fledged and perched across the street from the nest on the tip top of a pine tree! Woo hoo! And the endearing part was that Momma was perched at the tip top of another pine tree just a short distance away. Not one of her usual perches, so it was clear what she was doing…staying close. Then she flew over to a very high perch in a semi dead tree that the adults often use to watch over the whole domain….where she could see the fledged chick and the two remaining on the nest. At one point an intruder was wafting around and Mom gave a chirping call and in very short order Dad appeared on the nest. The intruder flew over and he escorted him away. Such awesome parents.

First Fledge!
Fledging season has officially begun! I found the first chick fledged from its nest on a cell tower. He was perched below the top of the tower, below the nest. But he also flew to the other side of the tower, so flight is good and landings were successful. His sibling remained in the nest with mom this morning. I watched for quite a while but on this stinking hot day, I knew I had more nests I had to check today, and he might sit there for a while! He kept looking up at the nest and thinking about how he would get there….gonna have to circle around a few times, but I had faith he could do it. I will recheck tomorrow if I can. This is the nest that I thought would be the first to fly, so this unlocked the fledging window for a bunch of other nests. I checked about three other nests and no one was flying…..few were even flapping ( one chick was). Maybe tomorrow. But this weather….oy vey. It’s miserable out there. I also found yet another new nest…..found one yesterday as well. Careful examination led me to believe that these last two nests are just being built this summer…..no whitewash which would indicate there had been chicks in these nests. I don’t know if they laid eggs or not. So we are up to 30 new nests this year. And those are just the nests I have discovered or been told about…..there may be more. I do not have enough hours in the day or volunteer monitors to follow all these nests. Now that it’s fledging time I have to get to all nests to confirm outcomes….and try to get the final chick counts. A nest is not successful until at least one chick is known to have fledged successfully. And this weather is making it very difficult. I hope the ospreys can handle it better than I can.
