One interesting example of source-sink management is the bald eagle. Despite
the fact that it is the US national bird, the US is a sink for this species,
and bald eagles are imported from Canada.
But I know of no neutral ground between the US and Canada!

IN scenarios such as the bald eagle, would it not seem prudent that canada
and the US discuss the animal's status before either one removed it from
the ESA? Is this done currently? Seems like they should!

I have no sources for this, just acounts that I recall reading. I defer to
anyone with detailed knowledge of the issue.
I don't know whether the bald eagle is considered endangered in Canada, but
when I was living in Nova Scotia (until 2000) they were very common on Cape
Breton. I recall that t
I would echo the comments of Mr. Aney. Ironically, the older Subaru's
(i.e., 1987) get better mileage, and have the option of dropping into
4-low, which is lost on newer models which don't even have real 4WD. I
would qualify this statement by saying that I have owned 4 different

Do you have scientific basis that the US is a sink for bald eagles? As I
understand it, with the mountain lions the source-sink dynamics occur on a
much smaller scale than countries. And a sink is really a sink. Like ranches
that literally kill the animals when the intrude, or areas where hunting

I'll back off on this. I have seen photos of dead bald eagles with gunshot
wounds near ranches, but if killing bald eagles is illegal, then I guess it
doesn't happen.

On the issue of cost-effectiveness, and the argument that there are no
