Update from Rob 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 JAZZEL |

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… 00:00:55 Added on 3/10/11 |

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! http://www.bioweb.uncc.edu/Bierregaard/migration11.htm JAZZEL |

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. Rob JAZZEL |

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! ROB |

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 |

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 |
