[obol] Frigatebird reports

[Alan Contreras]

I think Peter's thought has considerable merit.  Right now is probably the
single largest compressed unidirectional movement of large waterbirds of the
entire year, and for many species includes the Columbia River.  Anything
that lives by klepting might well follow such a movement.

"Every time I hear a political speech or I read those of our leaders, I am
horrified at having, for years, heard nothing which sounded human.  It is
always the same words telling the same lies. And the fact that men accept
this, that the people's anger has not destroyed these hollow clowns, strikes
me as proof that men attribute no importance to the way they are governed;
that they gamble--yes, gamble--with a whole part of their life and their
so-called 'vital interests'."

Albert Camus, 1937
