Thread subject: Our Osprey vs. Hurricane Florida et al
||09/06/04 11:19 am
||I am concerned about the path of the DPOC Osprey as begin their migration I fear for there lives! I do believe that all birds have instinctive knowledge of "things-to-come", such as, these enormous and powerful storms. Will they know that storms are approaching OR will they be surprised? Do any of you have information about this? BTW, thanks so much all of you for jobs well done. I'll contine "watching" the OBS Data base and Message Board, as I have thru 2003/04.

||I have been researching on and off and am continuing to do so about hurricanes and migration. So far nothing I have read indicates that they know about bad weather, though the direction of the winds seem to suggest something. Their instincts direct them and they will find the direction of wind to guide them to their final destinations. However, I also discovered that hurricanes or bad weather in general can "throw a bird off course" and sometimes a bird will end up in areas where that species was never seen before. There were also indications that birds will become tired in heavy winds and perhaps are lucky enough to land on a ship at sea. Raptors like osprey fly mainly over rivers and will fly higher and higher looking for thermals to carry them as far as 250 miles without ever flapping a wing. I found that interesting. Migratory birds do have "resting places" along the way and if the weather is inclement they will use these places. Of course it was mentioned if those resting places no longer existed, (building projects, etc), then the bird can be in trouble. Migration is certainly a mystery, with many theories, and ultimately one of life's miracles. I am continuing to "research" however, I just do a yahoo search typing hurricanes and bird migratoin, migration of osprey and bad weather, whatever I can think of and I am going to continue to look when I have more time.

||I just read some more info that was interesting regarding weather and migration.
A bird who leaves on a clear day and encounters fog will land until it passes, (it will look for anything to land on even a ship).
Most birds do not fly over the Atlantic because of the possibility of hurricanes. Only birds with good fat supplies attempt to fly over the Atlantic. Weaker birds fly along the coast, refusing to go out over the ocean.
The following I "copied"
If normal migration from Canada to Central America takes four weeks, they will continue trying to migrate for four weeks, even if they are going in the wrong direction. If, after four weeks, they are still on land, they will settle down and try to spend the winter. Unfortunately, they usually arrive here before the allotted time for migration has passed, and they usually move on after a few days.
The direction birds fly during migration seems to be determined by a combination of following routes based on past experience and, amazingly, on directions predetermined genetically. It has been shown that most songbirds, which migrate at night, use the North Star and the movement of constellations around it as a navigation tool. A bird may be programmed to fly southeast a certain number of degrees east of a north-south axis. Genes can mutate, however, and errors can occur.
There is a lot to read "out there"!!!

||Thank you so very much for a 'job well done' during your hours of research. Wonderful and intersting information Celeste. It does take a long time to do all this reading and I am most appreciative. I don't always have too much time lately to get involved in all thatt reading. Still trying to find time to finish David Gessner's osprey book. I guess it becomes a juggling act, for I always need to be outside after a 6-8 hr shift at the hospital. Besides I love to be with the eagles/ ospreys or Nature generally if the weather permits. Keep the info' flowing, Celeste and I 'll create new chapters for the Nature Journal.

||I think I remember the same concerns from us 1st timers last year in September. I just have 1 thought on the matter. This bird has survived for thousands + years. Clearly they know something about avoiding or hunkering down if they find themselves in a storm. Im surprised none of you feminists here have said this so let me help youz *wink* Obviously Betty is the smartest. She migrates 1st and earliest to avoid these ugly wind storms :)

||LOL.....ohhhhhhhhh I am so sorry Celeste...Thanks Mickey for alerting me to my error....Guess I just get carried away.......maybe I need to BE carried away. ..;-)
Too much excitement here........LOL
||09/06/04 08:28 pm
||YES Mickey.......we women have something called .... INTUITION! This helps us survive.....longer! As you mentioned...Betty is WOMAN.......AND SHE KNOWS! The girls get going early and play along the way....;-)) Hopefully all our ospreys can read the weather and do infact put down somewhere safe and ride out the storms.

||The question of why the young birds fly in the direction they do is a fascinating one.
In 2002 there was an incredible case of an osprey and honey buzzard (both satelelite tracked) finding themselves flying over the Atlantic about 400 miles west of Portugal.
Remarkably after 60 hours on the wing the young osprey made it back to Portugal. Sadly the honey buzzard did not.
Not sure I ever heard of the osprey again though.
The first two years of an osprey's life is indeed very dangerous.
I guess if any of "our" three make it back to Long Island thery will be fortunate.
None of the young English ospreys expected back in 2004 were sighted as far as I know.
But then as the Welsh osprey story illustrates they do not always behave the way we expect.
I guess there are years of research left and many new text books to write.
Maybe this site should start to write is own!
