Mr 79, the 23 year old Osprey...

Some news about our friend Mr 79, who has nested on the arboretum cam nest for years. He disappeared from that nest last Monday. Today I was out checking nests and saw an osprey sitting on the side of the road...it was 79. I approached with a towel in hopes of capturing him but he flew off. He flew fine, wings are fine. He kept  landing on mailboxes, garbage cans etc...and everytime I tried to get close he flew. He finally made some loops and got higher in the air and soared off over Lake Minnetonka and I lost him. I do not think he is doing well, but he is fully flighted so he can't be caught. Maybe this is the way old birds fail. I hope he is just having a bad day. Somehow he wanted me to find him I think.  Send him good thoughts...and let me know if you see him.
Thanks to all the people who tried to help, bringing boxes, taking photos of his band. I feel sad. I want him to be OK.

Osprey deterrent?

So many little dramas going on...I thought this one might make you chuckle, as it did me. A pair of Ospreys built a nest on a large radio tower last year...the company tore the nest down this winter. (You are supposed to have a permit from the state to do this). The birds started rebuilding, so the company went back up there and removed the sticks again and put a fake owl there. Now the Ospreys have a nest halfway built, incorporating the owl! HA HA. People think these birds are stupid...they do know the difference between a real owl and a plastic one. And they can be stubborn!

A new longevity record for us...

I am happy to report that our old friend Mr 79 is back on the cam nest at the Arboretum. I saw him last evening but wanted to confirm the band in better light. He has set a new longevity record at 23 years of age. He seems very hungry and his mate, 3S was being a little aggressive towards him for not sharing. That will change. I think she has been quite stressed having to defend this territory alone and now 79 will chase away those males and things will be easier for her. Welcome back 79!

Wood ticks and eggs!

It's been quite a crazy few days. I could write volumes but will have to condense it here. After several days of field work, a car breakdown (check engine light on) and an expensive repair, many nests have been visited...and some I still haven't gotten to for the first time. Lots of bands have been read, still many more to read. I like to get as many read before incubation as possible since once they start sitting, you can wait a looooooooong time to see legs. But with so many nests, it's just not possible to read them all during this short window before eggs are laid. I keep plugging away at it. I always say, read bands early and read them often. SO much is revealed by the changes in banded birds on a nest and by who is copulating with whom and who is visiting who! The wood ticks are out...oh my. And we do have our first eggs laid!  I have seen some of my old friends and sadly, some seem to have not survived migration. Our oldest male this year is our 22 year old and he has been waiting for his old partner for weeks. He connected with a few other females during that time, even ones that belonged on other nests. We were about to give up, and then his long time mate finally showed up! This marks their 14th year together!!! Fantastic. Break out the champagne! I have seen a great deal of chaos at a variety of nests, with too many Ospreys flying around. I observed a nest yesterday with two males doing elaborate and very vocal sky dances to impress the lady on the nest. I have watched many nests where a third osprey tried to land on the nest only to be chest butted off, or snapped at. At some other nests I have identified the same two Ospreys meditating in perfect peace as they restore their energies and prepare for what's to come. We have one nest that was taken over by....geese. There are some nests where I still have only seen a single bird, and too many nests that were removed, probably without permits. I have barely begun to put a dent in the work ahead. Much of it is a pleasure, some of it is frustrating. Waiting for two hours for a female to show me her leg bands...and getting no info! AHHHHH. I have to say once again, all my years of work and talking to people have created an amazing network of informants. So many wonderful people drop me a note with some valuable tidbit...so many regular committed volunteer monitors have been exchanging emails, full of conversations about behaviors, observations, questions. So many new volunteers this year are diving in whole hog, buying scopes, visiting their nests several times a week. Wow! And my experienced volunteers are so deeply valued, with all their knowledge about behaviors, band reading and what we call "fanatical patience"...a term stolen from my meditation teacher. It's required to do this work of collecting data and reading bands. Since it is National Volunteer Appreciation week, I extend a deep and heartfelt thanks to all of you who help me watch over these nests. Your efforts are so valued. 

 I am sure more birds will lay eggs soon, and new nests will begin to pop up. Please report any observations of Ospreys carrying sticks, building nests or just hanging out in a new spot. And a special thanks to Clarence and Gladys Osprey, who sent me a gas gift card today. I will be using it to come visit you very soon! So glad you made it back!

Arboretum nest cam

Well,well,well, For those who like a little soap opera action, the male on the Arbortum cam this morning (the day after the post below) is Z3...yes, it's Z2's brother, who was on the nest yesterday. I have screen shots of both bands. Both males have brought a fish for 3S too so we will see how the game of musical nests ends. Stay tuned! This fellow is working on the nest, digging a cup for the eggs, tho I have not seen a successful copulation yet.


We finally have a pair back on the nest at the Arboretum with the live cam. The female is the same one as last year, 3S. She is 5 years old this year. The male from past years, 79, has not been seen. He would be 23 years old this year if he returns. The oldest banded osprey documented in this study so far has been 22 years old. 79 has always been a late return in the spring so it's possible he may still show up. Meanwhile, another new young male has shown up. He is Z2, a three year old. He has been bringing 3S fish so perhaps he will be her new mate. Time will tell.

Wow...here they are!

As I predicted, the southerly winds have brought a boatload of Ospreys into town. Holy smokes. I was out all day trying to read bands and see what's happening. Some drama at some nests, with 5-6 Ospreys flying at onetime...territorial battles...and some birds on the wrong nests, some new mates. We will see what happens when the music stops and everyone has to sit. The wind gusting at 38 mph made band reading difficult ...the scope jiggling like crazy and birds having trouble hanging on to the nest and their fish. One female dropped her fish while trying to battle her way back to her nest. I watched one male land on his nest where a female was waiting...tho not his female of past years. He had a fish and she wanted it, but he was acting defensive, as I described in an earlier post. He was hanging his head, back turned to her, shaking his wings...and she kept jumping at him. Trying to scare him off? She finally bumped him off the nest. Ain't gonna get the fish that way honey. I was laughing out loud as I observed this little drama. He came back with the fish and she did it again, all the while food begging very loudly. Funny. Don't know how that one ended! Time will tell. Some nests are occupied by the regulars and things seem peaceful. I have a lot of bands to read and many more nests to visit. 125 miles today and 20 nests. I ran into one of my new volunteers out there today...great to have a face to go with the name. It's wonderful to meet the people who share this interest and passion. Thanks to you all for helping me watch over these nests!

More Ospreys...

Seems like the Ospreys are starting to arrive in the metro now in greater numbers. I visited 19 nests and found birds on seven of them. I have read about nine bands so far. And one male had his band read twice today on two different nests (as I did last Sunday also). I watched some drama at one nest with two Bald Eagles and two Ospreys chasing each other around. This is not uncommon this time of year, but always interesting to watch how aggressive the Ospreys can be when they feel threatened. Always interesting to hear that vocalization that means "oh no a Bald Eagle". Some males were working hard on the nest, bringing sticks endlessly, digging a cup for the eggs, some are still looking around for a female, doing the courtship dance in the sky with a fish. Some pairs are clearly old mated pairs, so comfortable together...but some show behaviors that indicate it might be a new partner. Males can become defensive, turning their back to a female, hanging their heads and sometimes spreading their wings a little bit and shaking them. The females seem to hold some power...is he good enough for me? There are just so many fascinating behaviors to observe!
