Thanks for saying this Ron;
I have to agree with this thread; I see any person who uses anything from
Nature as a "hunter", including birders. Hunting skills (which I lack to a
degree, including patience) are a prerequisite. I view folks who collect for
the furtherance of scientific inquiry (as is Ron) as responsible people. I
used to net butterflies to ID them, and though my hands were pretty good
then (wire jewelry craftsman), I found I was injuring about 1 out of 10. I
found this irresponsible, and now use the net to catch Deer Flies. (They are
trying to eat me....!)
I have said many times that I do not agree with the collecting/killing of
any living creature unless;
1.) It is for food. I have no quarrel with hunters who are hunting legal
game that have healthy populations *as long as* they are going to eat them.
I decry hunters who go Dove hunting and do not eat the birds, and I know
this goes on.....
2.)It is for the advancement of knowledge (as, it seems, Rons collection
is). I know many collectors keep butterfly collections as others keep a
stamp collection, and this seems a waste to me, and further, a
non-scientific collector would not know whether s/he were collecting a very
rare or endangered species until after identifying it, and many would not
3.) If the creature in question means active (not potential) harm to the
person. Why I use the net on deer flies, and slap mosquitoes.
I like the idea of not using the net, as a pair of good close focussing
binoculars (or even a cheap pair) will get a good ID, without having to
traumatize one of the most delicate critters around.
Fascinating thread, and by the way, I was out in my front yard this AM
(suburban Asheville), and was surprised by a Mourning Cloak flying around
me, and flying off around the house. I more associate them with more wooded
areas. Also found a Painted Lady (the one with 4 spots is American, right?)
dead in the garden center of Wal Mart in Clyde NC (west of Asheville)
