Thread subject: Migration Update
Name Date Message
karen 08/29/05 10:08 am Greetings,
Migration is happening. One of our birds is on the move.
Check out the new maps for Homer and Conanicus at:

is still hanging around his home turf.)

FOB Webmaster 08/29/05 10:31 am How interesting that Homer went west to the MD mountains, away from the Bay.
Marie 08/29/05 11:44 am It is so interesting to see these birds move south on these maps. Certainly great fliers when the weather is to their advantage. Perhaps hugging a ridge of mountains protects them from some nasty weather, however I wonder if the lakes, river, and streams are shallow enough for fishing. Mountainous lakes are often quite deep.Hopefully this bird will find everything it needs.
FOB Webmaster 08/29/05 11:57 am He's close to Harpers Ferry National Park, and the Potomac River there is pretty shallow, so he could find some fishing there.
Mickey 08/29/05 12:03 pm maybe he senses Katrina and is getting out of dodge fast.
Anne 08/29/05 01:02 pm Dont raptors choose to fly along ridges because of the thermals and updraughts? It is interesting that most ospreys passing through the north of England are seen over the hills rather than at the coast.

I have just been up Ribble Valley into the Bowland Fells to see a beautiful 1st winter grey phalorope on a tiny pool in a farmers field.( It will be migrating from Greenland/Canada down to the west African coastline.) The farmer says he has seen 10 ospreys going over his land in the last two weeks alone. They will be Scottish birds going south.
karen 08/29/05 01:27 pm i think that I remember that the osprey does not use the thermals on migration because unlike most raptors the osprey stops on its way south and will eat and rest several times on its trip.
FOB Webmaster 08/29/05 01:34 pm Yes, that's what I've read -- the osprey is a much stronger flyer than other raptors, so it doesn't have to rely on thermals. And that's also why it can fly over deserts and large bodies of water when other raptors can't.
Cecilia 08/29/05 02:06 pm Thanks for continuing to post these updates Karen...I always forget to check on Bierregaard's site until you remind us with his emails.
