I wasn't arguing that bald eagle killing doesn't occur Bill - I just was
unaware of it at least on a widespread scale. With legalized hunting or
killing of mountain lions, there are records that can be scientifically
analyzed, at least. I also thought that the scale of source-sink management
was probably more effective on a smaller scale than countrywide. And the
fact that some people on the list have mentioned that in some states bald
eagles are abundant while others they are not seems to indicate that we
can't really say all of the US is a sink. Even within a state, I'm sure it
varies. The mt lion management dealt with within-state management like one
rancher may create a sink whereas Big Bend NP may be a source. Though
another study seemed to indicate that really Mexicos del Carmen is truly the
source... It's an interesting and complex topic.

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.

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 is
more active. I don't know of any active killing of bald eagles and such a
thing is prohibited, no? Just because we may not be a source does not
necessarily mean we're a sink. The bald eagles are on the rise in the US
aren't they? I also thought they WERE removed from the ESA, weren't they??
