First birds are back on the breeding grounds

    
Migration is in full swing. At least five of our seven satellite-tagged birds are on the move and three of our GSM birds are home.

I changed the map for the GSM birds, so only the sprig tracks show. This makes it easy to pick a bird and slide his marker along a track and see what the other birds were doing when that bird was at a certain point on his migration.

This map is a day old (as of the 30th), so things have changed a bit. Donovan is already up in North Carolina. DC birds Ron and Rodney are running neck-and-neck on their race to get back to the Anacostia River. Rodney took the very hard way to get from South America--going over water the whole way to Cuba. We've never had a bird go so far west leaving South America.

Belle is at a very interesting lake in Haiti, called Lake Azuei, or Etang Sumatre. All three times she has migrated north, she has made a detour to get to this lake for a mid-trip top off.

North Fork Bob is in Cuba (we've had new signals from him since this map was made).

Snowy hasn't started migrating yet. This will be his second trip north. These teenagers often "get up" late.

Sr. Bones is probably on his way back to Nantucket. His radio failed last fall just as he arrived at his wintering retreat in the Andes. We suspect he'll be back on his territory soon.

Over in our GSM (cell-tower) birds, we have three birds home. Edwin was the first to make it back to at least the vicinity of his nest on March 26th. He's been in Connecticut, where he spent most of his time after his nest failed last year, since then and hasn't been back to Fishers Island yet.

Quin got back to Tangiers Island on the 27th. Most strangely, he kept right on going and is now up on a lake on the Delmarva Peninsula about 50 miles north of his nest. 

Nick
has been on the western shore of the Chesapeake Bay at the mouth of the Rappahannock River, only 25 miles from his nest on Tangiers Island, but hasn't been over to the island yet.

DJ was in Haiti heading west on the 25th. We hope he'll show up in Florida this week sometime--not too many cell towers in Cuba.

Woody was still in Venezuela on the 28th, which is remarkably late for an adult to still be on his wintering grounds.

No word from Tango or Icarius in so long that it's pretty clear that we lost them.

As always, you can look at the details of all the birds' tracks on Ospreytrax.com.
   

Our new website is on line 


I've seen a steady trickle of new subscribers to these updates, so for those new to this particular corner of the Osprey universe, there is an older site where you can browse 14 years' worth of maps, including the early maps for several of the birds on this site. On the new site you will find a description of the technology of tracking and three master maps that are automatically updated every six hours. One is for the eight adults with satellite tags (PTTs), the second for the eight adults with cell-tower transmitters (GTTs), and the third for our eight juveniles, all of whom are carrying PTTs.
     
     Below each map I've got a summary of who's going where. You can zoom in and out on these maps. Clicking on any path will get the bird's colored dot to that point. Hovering over the dot will identify it, clicking on it will bring up the time and date info. If you slide the dot along the bird's track, all the other birds' dots will move to where they were when your target bird was wherever you have it on its track.
     
     A few individual maps are up. If you see a bird's name underlined in the list beside the interactive maps, it has a map.
 
    Because the maps are automatically updated, you can check in whenever you're curious about what our flock of 24 Ospreys is doing. (No one has ever followed this many Ospreys in the same year.) The best time to check is when cold fronts move in. They usually have strong winds from the north, which is just what our birds want to help them on their way.
      
     The old site will remain active, but only as an archive of our the 2000-2013 (spring) data.
     

    Also, if my email is in your address book, you should change it from rbierreg@uncc.edu to rbierreg@gmail.com.
