Thread subject: Migration Routes
Name Date Message
Tiger 07/15/04 03:24 am I am very familar with European migration routes but I do not know much about American ones.

So does anyone know anything about the routes that our feathered friends will take on the long journey south?

I did a Yahoo search for New York osprey migratory routes and the above is what I came up with. I haven't studied it in depth, but if you scroll down there is a chart that shows osprey from Shelter Island, which is Long Island and the route they follow. I am stealing time on this computer this morning! Too much to do! Hope it is informative.
Celeste 07/15/04 05:35 am I was quickly going back to the site and there is a full map of migratory osprey on the East Coast of the US. What I am hoping to do this Fall is to travel as far south as one can go in New Jersey, (Cape May)...New Jersey is next to New York. From what I understand it is THE place to see migration taking place for all birds. From my readings osprey are solitary migrators, however in this spot, they say this is the only place you will see several of them flying together. Let me know how helpful this site was.
Tiger 07/15/04 06:08 am Oh yes they are fascinating. It is clear that the birds have to survive a long journey over water.

Yes ospreys migrate by themselves. They do not even aim for the normal "funnel" points. For example many birds aim to cross the Mediterranean Sea at Straits of Gibraltar. Ospreys do not.
Shelley 07/15/04 08:41 am Hey, Tiger. Have you got your hands yet on a copy of *Winged Migration*? You will LOVE it!!

I just bought myself the DVD. Now, all I have to do is take my newly purchased DVD player out of its box (going on 2 weeks, now...!) and hook it up...and I'll be all set.... ;-)
Tiger 07/15/04 09:09 am No not yet Shelley but I have noted it!
Marie 07/15/04 09:27 am Guess I will check these web sites out after work today. Guess too I will have to do some searching about those Ospreys that move up the west coast in migration and then return southwards in the fall. I know we have a population in Baja California that, rather like the ospreys in Florida, do not migrate. They stay all year round and breed at the same place too. It has been suggested that many of the ospreys on the west coast do migrate to Argentina and Chile
Cecilia 07/15/04 09:44 am From Poole's book:

"Fall recoveries of banded ospreys suggest that they migrate south on a broad front. During September, for example, ospreys from the northeastern US scatter south and west of nesting locations".

"They do not ignore land forms that can help guide and concentrate their movement. They appear regularily along north-south mountain ridges in the eastern US, for instance, and along the peninsulas of Florida".

"Recoveries in the Caribbean suggest that they do not funnel along the chains of smaller Caribbean islands or along the Central South American coast, but instead fly directly across the Caribbean to their South American wintering grounds".

"Observers from tropical regions report that most ospreys reach winter quarters by late November."

On a map he shows that most of the northeastern ospreys end up in the north western regions of South America - very much concentrated on the coast but some head inland to rivers - and in southern Central America where they are joined by ospreys from the midwest and west populations.

There are locations along the east coast that are well know for oprey migration sightings...Cape May, New Jersy for one, where people have seen hundreds of ospreys flying over in "clouds". One of these days we're going to book a B & B for a couple of days during migration and try to see a sight like that :-)

Ivy 07/15/04 10:16 am Living in SE PA puts me in an enviable position of being able to take day trips to two of the East Coast fall bird migration hot spots: Cape May in NJ and Hawk Mt in PA. If your special interest is ospreys, the total number sighted during fall migration is almost three times larger in Cape May (1,975 in 2003) than at Hawk Mountain(680). You're not always guaranteed to see record breaking numbers or clouds of migrants at either of these locations as weather conditions are a big factor in determining the migration numbers on a given day. I particularly like Cape May in the fall because of the migrating songbirds and Monarch butterflies, which are quite a site if the birds of prey are not putting on impressive displays.

Here are two sites that provide additional info regarding the fall migration:
Cecilia 07/15/04 04:21 pm Thanks Ivy...I'll keep those sites for our future trip !
Shelley 07/15/04 07:50 pm Thanks for those links, Ivy! You are so lucky to live close enough to visit those places regularly!!
Marie 07/15/04 08:52 pm Thanks Ivy...I have heard of both those places before and have thought how awe inspiring those places would be to visit and watch all the RAPTORS passing through on migration. Your numbers of osprey are huge. We may see a dozen or so. We do have a place here in Victoria where hundreds of Turkey Vultures 'KETTLE', and other Raptors. 'Kettling' is where the birds use the warm thermals off the land to circle higher and higher to gain altitude and then drift across the Straits of Juan de Fuca.) This is an expance of water that connects us to the coast of Washington. Here the migrant raptors drift/fly their way southward through Washington, Oregon, California, Mexico and onward to Central and South America. When I have watched this great movement I have seen raptors turn back to our coastline, even when half way across the water if the weather isn't just PERFECT for their migration. Amazing stuff. Thank you to all who have posted web sites to get info on MIGRATION.
Marie 07/16/04 01:34 am I was unable to find much info tonight on West Coast migration routes for ospreys. Much more research has been carried out in the East. It seems there are three distinct populations of Non-migratory Ospreys. One can find ospreys that reside all year round in southern Florida, Baja California and the Pacific Coast of Mexico. For those ospreys that do migrate it is a differnt story of survival. Despite the ban of DDT in the USA in 1972 it is STILL USED in South Central America. This info is alarming for many of our ospreys migrate to those areas. Ospreys breeding in North America and Alaska fly south in the fall to their wintering grounds. Their routes are often fraught with danger. Once they arrive at their wintering grounds they then have difficulties with habitat loss. Deforestation, slash and burn causes land erosion. The run off 'muddies' the waters/streams/lakes where ospreys feed making it difficult for fishing. DDT contaminates other food sources that they may feed upon, so it is amazing that these magnificent birds survive at all. Next time we see an osprey glide overhead we need to be so thankful for pioneers like Dennis Puleston. Their vision for a safer environment, free of harmful chemicals and contaminents allow us to watch in wonder at the grace and beauty of this special Raptor. Theirs is a story of a 'come-back' that was almost impossible. I have watched in awe as one or two ride the warm thermals higher and higher in the sky. They fly free and we earthlings can only watch from below, but, if we are willing we can allow our hearts to soar with them on a wing and a prayer.
Celeste 07/16/04 04:55 am As I have been "catching" up with our messages and reading how eloquent, insightful, etc, we all are, I was thinking there could be "someone" out there who could compile all of our "input of info, osprey experiences on the "outside", observances of this nest, references, thoughts, questions", and put together a really good book. Hmm, it could be called "The Observers", or "Osprey Guardians", "The Followers", or....!!!!! It has been so nice to have these "daily chats", learning and expressing ourselves to one another, etc!
Celeste 07/16/04 05:12 am Oh and Ivy, thanks so much for that Cape May website. I hope to make a trip down there in the Fall.
