Fall 2012 - Rammie found a cell tower in a most unlikely place on the Guajira Peninsula in northeastern Colombia in March and uploaded some data, so we know where he wintered, but not how he got there. The white arrows show the most likely route. We'll find out when he gets home and has more time to dump data to us.
20-22 Sep 2012 - Rammie (purple R) started migrating a day after his neighbor, Bridger (salmon B), but had caught up to him by midday on the 22nd.
9-12 June 2012 - "Rammie" (who nests near Big Ram Island) joined our flock on 9 June. As of the 11th he was feeding one youngster.
9-12 June 2012 - [Same text here on Bridger's page] Here are the points for both Rammie and his neighbor, Bridger, during the first 3 days after they got their high-tech backpacks. Note that Rammie was also out after some pogies. While they agreed that fishing for menhaden was an option, what is most striking about this map is how different their fishing behavior is.
     This is why we're tagging adult males. The GPS transmitters, and especially the new "cell-tower" transmitters, provide a remarkably detailed picture of how these birds are using the environment.
     This is just what we have seen when we followed neighboring Ospreys from the Westport River colony in years past--just like human fisherpeople, each Osprey has its favorite fishing holes.
     Rammie is apparently working the herring run on the headwaters of the East Branch, while Bridger is hugging the coast.

For the rest of the summer, I'll map both birds together and put all the maps on Bridger's page.]
OK, Rammie gets his own set of maps from now. Here's the start of his travels--476 miles (766 km) in the first 2.5 days of travel.
     He's an adult that we haven't followed before, so we have no idea where he's going. He does, of course, although he has no idea exactly how he's going to get there. We know from following other adults over a series of years that each year's path can be very different, although they always end up at the same spot.
22 Sep 2012 - Rammie crossed Chesapeake Bay around 1 PM on the 22nd. I've picked out hourly locations and connected them to see how the track we would have seen from a satellite, rather than a cell-tower based PTT. In this case, we see some "wiggle" as Rammie's drifting a bit to either side of the hourly track, suggesting he may be using thermals.
     Because we get our data from text messages (like the parents of most teenagers), we need to have the birds close to a tower around midday, when they transmitters are programmed to dump data. If the birds are out over the water, or in some remote location, we may miss several days' transmissions. The GPS units do keep all the data, so the next time we hear from the birds, we'll get all the gaps filled in.
     We're currently in the 4th day of cell tower silence. Both birds are presumably quite a ways south of where they were on the 22nd.
Fall 2012 - Rammie got to South America flying under our radar. Somehow he made it all the way to Venezuela without being near a cell tower around mid-day, which is when his transmitter is programmed to text home. The white arrows indicate the most likely route he took. The one thing we do know is that he did not follow the orange line from his last location up in Virginia down to his wintering grounds in Venezuela.
Winter 2012-13 - Our data for Rammie's winter activity begins in early Feb. From that time until he left on 15 March, his core area was a remarkably small 0.25 square miles! Amazingly, it's not even
15-17 Mar 2013 - Here's Rammie's track through northwestern Venezuela. So what's up with the zig-zagging? This is a more mountainous part of the country than it appears on this map. Scroll down...
(I marked the small reservoir where Homer, one of our Martha's Vineyard juveniles, spent two winters.)
15-17 Mar 2013 - Here's a rough track of Rammie's movement on the 15th -17th. Looks like he doesn't dodge all the mountains in his way, but it also looks like there's no way to avoid them all.
