Animal Planet on...a make over for a Trumpeter Swans habitat...before was the story of the Mormon's on PBS...and before The Matrix at the Down where I had spagetti...I dont know what's happened to my blogger spell checker!!...used to work...must have clicked something!..
The Wildabeast migration might be getting messed up by global warming...brb...Gnus they're called...and ten thousand...about one per cent of the population...didn't make it across the river...picked the wrong spot was one guess...the other that the river was unusually high because of heavy rains...they're waiting and hesitating to cross was on the Animal Planet show...
The migrations are kinda like the Pyramids...the Pyramids like clocks and geodisic markers...show the orientation of the Earth...any change and the Pyramids would be out of orientation..likewise with the migrations...if things get out of wack they'll alter...though I think migrations in the first place were caused by climate change...??...brb...

An example is the migration of continental populations of Swainson's Thrush, which fly far east across North America before turning south via Florida to reach northern South America; this route is believed to be the consequence of a range expansion that occurred about 10,000 years ago.

Well...I'm collecting that ten thousand year date...brb...well...Grey Whales have been around for thirty million years..and the California Greys...my next Seven Wonder!...have the longest mammal migration...would like to know how long ago it started...brb...here's a list of the different whales and they're migrations...http://www.whaleroute.com/migrate/
a guess would be that they have been doing this for thirty million years!!...going from the cold poles where they eat to the warm tropics where they breed...brb...this site explaing that the Bearing Sea a few thousand years ago was ice locked...and didn't pemit the whales to go where they go now...other animals too change where they went....and suggest they adapt their migration readily to changing conditions...
which makes sense...and hopeful news...
the "wonder" of the whales is that they're still around...having been brought back from near extinction...an Atlantic version did go extinct...and the West Pacific that migrate along the Asian coast are only a hunderd or so...
