New migration update from Rob...Check out the Vulture :lol:


Greetings from an iced-in Charlotte. Typical winter mess down here. Snow then rain, which all froze, so you can ice skate down our street.

All our Ospreys are down in much warmer places and they're all doing fine. I updated all the maps through the end of 2010. Just a couple of months before the adults head north!

There are quick links to the new maps for the youngsters (interesting movements by all, including our S.C. bird, Buck) on the Migration 2010 page:




I've also included links to the newest maps for all the birds (scroll down to the list of all birds with links to maps and bios). Where I have indicated the latest updates, you can click to go to the newest maps.

On a related, but non-Osprey topic:

Some of you may have heard of a satellite-tagged vulture found in Saudi Arabia being "charged" as an Israeli spy. It's true. Happy ending--the vulture was released.




While we've never had an Osprey accused of spying, we did have trouble getting a transmitter back from the Venezuelan military, who thought it was some sort of spy device.

Enjoy and stay warm.

Update from Rob :smile:

Osprey-philes,

I know we're all chomping at the bit, ready to follow our birds north. So far, as of the 28th, none has started moving yet. Any day now! I haven't done the February maps yet because if I don't grade the pile of exams sitting on my desk, my students will lynch me and then there wouldn't be any more maps at all!

Soon,
Rob

Just got this in my alerts didn't know if you have seen it Jazzel I thought it was cool

Each fall, ospreys all along the U.S. East Coast begin a southward migration that can bring them as far south as Venezuela, Brazil, and even Paraguay. They move from fishing hole to fishing hole along…

Kitten, no I didn't see that video, but I do know the migration routes. The video is a bit sophomoric, but great they are bringing attention to Osprey migration :smile:

They left out the Dominican Republic...where many ospreys cross, adult and young, and are shot :cry: They also left out the migration, over the ocean, many young ospreys take.... :cry:
And much more, but good to get the interest :thumbup





If you want to see the fishing hole moves, both during migration, and while still in their nesting area, click on the osprey's map.

Update from Rob (3/26)...any thoughts???

North Fork Bob and Sr. Bones are on their ways north. Sanford may also be moving. Both he and NFBob will text us tomorrow. Bob, by that time could be in Cuba. Our last signal from him was out over the Caribbean.

More news soon!

A very, very interesting update from Rob.

All the adults have been home for a while. Now we have our last bird moving. Buck, born in South Carolina back in '09 is back in the states. His movements are further confirmation that the young birds are an apparently never-ending source of surprises. It looks like he's going to take us on an interesting ride.

http://www.bioweb.uncc.edu/Bierregaard/migration11.htm

Another bit of exciting news is the recent sighting of a satellite tagged Osprey on Martha's Vineyard's south shore. It was on an nest pole (no nest) with another Osprey. It wasn't any of the birds we are currently following, so it has to be an old bird whose radio went dead. Our most likely candidate is Conomo, born in Lobsterville on the Vineyard back in '07. He came back in '09. We lost his signal over in CT sort of all of a sudden, with no further messages. We've got an APB out on him. If he starts showing up somewhere, we might be able to get a spotting scope on him and try to get a reading on his band.

Tagging and map updates from Rob. The adult male he was trying to tag was on the Ayers Island cam nest, he banded the female while he had her. He's going back on 7/12 to put transmitters on two of the juvies.


Greetings,
It has been a very hectic spring. Selling our house in
Charlotte, finishing up at UNC-Charlotte after 15 years, house
hunting in the Philadelphia 'burbs, and a trip north to tag new
Ospreys has left little time to do much else but breath. Hence the
long silence from Map Central on what our Ospreys have been up to.
When last I updated you, all our adult males had returned to
their nesting areas and Buck was up in New Hampshire. Buck has been
almost constantly on the move between Virginia and New Hampshire. I
haven't calculated how many miles he has covered yet, but I believe
it will be well in excess of 4,000 miles since he made landfall at
Cape Fear, NC, back in late April. He has now been in 17 states, only
missing Vermont, Rhode Island, and Maine east of the Appalachians. He
keeps trying to get back home, heading southwest from wherever he has
been, but when he gets to Virginia or NC he turns around and goes
back northeast. Most strange.
My trapping trip in May was disappointing and frustrating to
say the least. With 5 transmitters to deploy, I was only able to tag
2 adult males. I got one in Long Island (neighbor of North Fork Bob),
who was dubbed "Tucker" after his home town of Mattituck, and a male
on Martha's Vineyard, whom we're calling the Katbird. This name plays
on his nesting location on the Chappaquiddick side of Katama Bay.
The trip got off to a great start on Long Island's North
Fork. We caught our target bird there in just a half hour or so and
started to feel cocky about the trip. Then New Hampshire happened.
I have begun a new collaboration with Iain MacLeod of the
Squams Lakes Natural Science Center. New Hampshire hosts a healthy
population of some 60 Osprey pairs. While some of these are found
along New Hampshire's modest coastline, most are scattered about the
state's inland rivers and lakes. Our plan for the first year of this
new study was to tag 2 adult males and 3 juveniles. We want to
compare the hunting behavior of inland birds to those we've tagged
along the New England coast and to add some more juveniles to our now
fairly substantial data base on first migrations.
After the New Hampshire leg of the trapping trip, we have
downsized that plan to probably just tagging 2 juveniles. Tagging
males is never the guaranteed deal is it with juveniles (I'm 31 for
31 trapping post fledging young), and we only had 2 nest that were
accessible (via bucket trucks). As it turned out, the males at both
our target nests did not feel compelled to sit on eggs after we had
trapped their females, so I left New Hampshire 0 for 2 and headed for
Martha's Vineyard, where I planned to tag 2 males.
On the Vineyard I had the luxury of lots of nests to chose
from, so I expected that I wouldn't have any problem getting 2 males.
I still thought that after we tagged a bird at our first nest without
even having to catch the female first. Then I got a serious dose of
humility as we set up at 4 more nests and could not catch another
male. We caught the females at 3 of these nests, but only had one of
the four males even land on the noose trap. Totally frustrating. One
interesting bit of data that we collected in the process was
discovering that the female at the Lake Tashmoo nest where we have
tagged 3 juveniles (Tasha, Belle, and Meadow) is a 15 year old bird
banded as a nestling over in the Westport River colony.
To add to the sad tales, one of the nests in New Hampshire
where we planned to tag young blew down in a violent storm just last
week, and the Katbird's nest failed, most unfortunately because of
our trapping him. This has never happened to me or anyone else who
has tagged adults around their nests. We've had some birds stay away
from their nests for extended periods, but have never seen a bird
react as negatively as the Katbird, who stayed away from the nest for
3 days. The good news is that he's back around the nest with the
female, so if they both make it through their next migration cycle,
they'll be back to breed again next spring.
And then, piling it on, we learned that our Long Island bird
was killed about a month after we tagged him when he flew in front of
a bus.
Wildlife biology is always invasive, and our studies often
stress the animals we are studying. We do everything we can, of
course, to minimize the stress, but cannot avoid it completely. As
sad as it was to see this nest fail, I'm still comfortable that the
knowledge we've gained about Osprey migration and conservation is
worthwhile.
I've moved from Charlotte to the Philadelphia area and will
now have time to update the maps. On the 12th of July I'm heading
north for another trapping safari. We plan to tag 2 juveniles in New
Hampshire and either 2 juveniles or 2 adult males on Martha's
Vineyard.

Best, Rob

Two updates from Rob

8/28/11


Sorry for the long silence. My life has been totally consumed by moving from Charlotte to the Philadelphia area (Wynnewood). I've barely had time to keep up with our tagged Ospreys, much less post any new maps.
Several of the faithful are starting to rattle my cage, eager for news. With the storm charging up the coast, it seems an appropriate time to take a few minutes off from opening endless boxes of "stuff" (see George Carlin on this) and at least give an update.
The most amazing news is that Buck, our SC youngster from '09 finally found his way back home. It only took him 4 months after hitting the NC coast back in April and about 7500 miles to do it. His maps are pretty unbelievable. (They're pretty much up to date--just missing the last move where he finally made it back to his nest area).
Our 2 young from last year-Thatch (DE) and Belle (Vineyard) are both pretty much settled down in the Amazon. They're on a 8-9 month countdown before their first return trip north next spring.
Our adult males (Bob, Sanford, Katbird, and Sr. Bones) are all hanging around their nests. Only Sr. Bones raised young this year--it was his first successful breeding.
Newly tagged birds are moving around a bit. Saco (female from NH) moved down to NJ after staying very close to home up until she decided to head south. She
got there a couple of days ago. Signals from her are a bit strange and worrisome. We're waiting for the next round of data.
Our 2 Vineyard young from this year, Snowy and Henrietta, are wandering around. Snowy's in western Long Island and Henrietta's bouncing around between Cape Cod and the Vineyard.
So, how will the hurricane affect our birds? Obviously that's a tough one to answer. The good news is that none of the birds, with the exception of Saco, seem to be ready to move south, so we won't have any birds venturing out into the Atlantic and the teeth of the storm. I suspect if it gets really bad, they'll just get down on the ground and tough it out. We may, on the otherhand, find one of our birds far from home. Birders love to go out after big storms like this to look for exotic birds for their state lists.

We'll just have to keep our talons crossed that they all weather the storm.

Stay safe and dry.
ROB


8/29/11

Just testing a new email system (finally forced to abandon good ol' Eudora) to report that our New Hampshire young female, Saco, was doing fine in New Jersey. We had a glitch in downloading the data that made up nervous. By now wherever she is, she must be pretty wet!

Sorry for late posts, I'm documenting my nests…not an easy season

Update from Rob, 10/4/11

I'm out in Duluth at the annual scientific meeting of the Raptor Research Foundation and am way behind on maps, so I thought I'd update everyone on who's moving and who's not.

Henrietta (MVY youngster) is safe and sound in Colombia--our first bird across the Caribbean. Sr. Bones (adult male from Nantucket) has been in Cuba for a while. He was recently joined there by Katbird (adult male from MVY) who may have skipped Florida and done the Carolinas to Bahamas route. Will know more when more data gets in. Buck, our South Carolina teenager, who wandered all over the eastern US in search of his natal territory, spent about 6 weeks there and is now heading south. Last data from him were from Florida, but that was several days ago, so I suspect he may be in Cuba by now.

Saco, our New Hampshire youngster, who was the first to head south, is completely stalled up in West Virginia. Homer did the same thing back in '05 or so--headed south and then turned around and retreated to the mountains, where he stayed until late October. Sanford and North Fork Bob, both adults from Westport River, MA and Long Island, are lingering around their breeding grounds (neither raised young this year). Finally, Snowy, our other Martha's Vineyard juvenile, is still enjoying the good life on Hempstead Bay in western Long Island. Sort of in Great Gatsby country.

Should be able to catch up on all the maps next week!

Rob

Kitten...no bad news :ohyes:

Up date from Rob today


I've updated the maps for 4 of our 8 migrating birds: Saco (NH), Sr. Bones (Nantucket), Henrietta (Vineyard), and Buck (SC). I'll be working on the remaining 4 over the next few days.

Current state of the migration: Henrietta and Sr. Bones are both safe and sound in S.A. Katbird, Snowy, and Buck are all in the D.R. Buck started out across the Caribbean and changed his mind after an hour or so. Maybe he flew into some bad weather. Saco and North Fork Bob are in Cuba, and Sanford is bringing up the rear, somewhere along the northeast coast. (Hope he turned out the lights.)

Update from Rob today. Migration, not easy on our birds, and those that track them

This is a hard time to be playing catch-up on the Osprey maps. Lots going on. Sort of like painting the Golden Gate Bridge. By the time you get to the end it's time to start again.

Sr. Bones is safely back in his mountain hideout in Colombia. I think we lost Henrietta. Still waiting for the next update from her, but it doesn't look good. Quite mysterious, as she was safely across the Caribbean and in an area with very little human presence. Her locations for the past week or so have all been in a very small area--about 1/10 mile across. Hard to figure out what might have happened to her. No people around and it doesn't look like good habitat for Great-horned Owls, so I can't blame them this time.

Sanford (updated today-interesting maps comparing two fall and one spring trip for the same bird) is in Florida, not far from his winter home in the Bahamas. Will he go to Cuba first like last year?

Buck has tried to cross the Caribbean twice but both times has retreated to the D.R. Maybe he ran into bad weather, or maybe he really does have ADHD. He couldn't seem to remember where he was going all summer. Now he gets out over the Caribbean and seemingly asks himself, "Now where was I going?" And then goes back to the D.R.

Bob's still in Cuba, where he spent way too much time at a fish farm, while Saco finally made it to Haiti. Snowy is hanging around a reservoir in the D.R.

Katbird (updated today) is currently out on a nerve-wracking (for us) crossing of the Caribbean. He made it all the way to the British Virgin Islands (farther east than any of our birds have gone in the Caribbean) before turning south. He ran into some bad weather, but seems to have avoided it.

Two updates from Rob 11/1/11

Sad to report that we lost 4 of our 8 migrating birds in the space of about 9 days.

Saco (NH juvenile) and Katbird (MVY adult male) both went down over the Caribbean. Henrietta (MVY juvenile) had safely crossed the Caribbean and was settled down for a while along the shore of the Gulf of Venezuela where Buck spent a lot of time. She then started moving inland and stopped moving in the middle of nowhere. Her loss is hard to figure out. It always might be that she lost the transmitter, but I think that's unlikely. She stopped moving in an area with very little human presence (based on the Google Earth images) and wasn't in a woodlot, so Great-horned Owls are not the likely suspect that they sometimes are. Sanford (adult male from the Westport River in SE MA) stopped moving just east of Orlando. This one's a real mystery. He was flying along heading south at 4 PM on the 23rd and then apparently fell out of the sky. He was cruising along about 25 mph at the time. Then, an hour later, the next location is in the middle of a cattle pasture only 3 miles from the 4 PM location. I can't come up with a scenario that fits the data. We should be able to get this transmitter back, so there may be some clues when we find the transmitter.

Someone needs to tell Mother Nature that we don't need any more "teachable moments" about the dangers of fall migration. We get it.

Of the survivors, Senor Bones is safely nestled into his mountain hideout in Colombia, North-Fork Bob is safely across the Caribbean in Colombia, Buck seems to be enjoying life on Cabo Beata in the D.R. after two aborted crossings of the Caribbean, and Snowy has at least temporarily settled down in the D.R., which makes us nervous, given that all 4 juveniles that tried to overwinter in the D.R. were shot.

Belle and Thatch, our teenagers on their "gap years" down in Amazonian Brazil seem to be fine.

All maps are pretty much up to date


Sanford's body and transmitter have been recovered. Rob wrote 11/5/11.

"One bit of good news after all the bad news of the last couple of weeks is that Sanford's PTT has been recovered. Along with his body. It's being sent to the Audubon Center for Birds of Prey to see what they can tell about what happened. My current best guess is that he was shot."

From Rob today....

Sorry to report that we lost another one of our birds. Buck, our most peripatetic youngster from 2009 (who covered more than 8,000 miles in the eastern US looking for his natal area in South Carolina) either died or dropped his transmitter. Another total bummer, as it would have been SO interesting to see what he did on his second return to the states. He was back in his wintering area from 2009-2011 and everything seemed fine until one day his transmitter just stopped moving. Absolutely know way to know what happened, so we can just be optimists and say he dropped the transmitter. He was in a National Park so perhaps a bit less likely to be shot than in other parts of the country.

On a more cheerful note, Snowy seems to have settled down and is now doing the teen-age Osprey road trip thing, exploring the Venezuelan countryside.

North-Fork Bob surprised us by abandoning his wintering grounds, after only 4 days there, and retreating back down into the Venezuelan lowlands. He's in very strange country, as far as wintering Ospreys go, only about 35 miles from where Snowy has set up shop.

Enjoy the maps and the holiday season!

Rob
