[obol] photo quiz and people on obol

Oregon birders,

This discussion has surprised me. I was even more surprised by who 
started the discussion. I actually have to agree with Mr. Phil Pickering 
on this one where in the past I have found his character towards gull 
identification to be at times (though not all times) overly speculative, 
in the case of Mr. Chris Warren's and Mr. Dave Iron's photo quizzes he 
is dead on.

Whereas I had absolutely no problem at all with the gull (now divulged 
as a THAYER'S) in Chris's initial "Quiz Bird #5," Dave Iron's gull quiz 
of three different individuals includes two birds that, given the single 
photos, are absolutely NOT discernible as non-hybrids.

Additionally, OBOL is a public forum. Chris's Bird Quizzes absolutely 
fall within the very general guidelines for the content of this 
listserv. Mr. Sullivan (and anyone else for that matter) need not 
participate if he wishes not to--in anything suggested by this forum, 
including identify birds from bird photo quizzes. The quizzes need not 
be seen as competitive either. They can be tools for ones own personal 
and private learning--just take a look at the pictures (lots of us do 
this already), make note of the possibility or possibilities that come 
to mind as an answer and keep it to yourself. When the answers are 
posted your learning can then continue. It it pains you so to be wrong, 
then don't participate in the activity--simple enough.

On Frontiers of Bird Identification listserv: Dave is throwing out the 
baby with the bathwater on this opportunity. I subscribe to that list 
and have learned tremendously over the years from the prose and photos 
of its many contributers. It has not been "taken over" by laridophiles, 
though the gull threads are very frequent and often there have been 
herds worths of horse corpses beaten on impossible to identify gull 
photos. If I see "Thayer's," "Kuemlian's," or "Iceland" Gull in the 
subject line I generally delete those messages now. I rarely look at any 
of the posts that have "Western" or "Glaucous-winged" gull in them 
either. But, I do read many others such as those on shorebirds, or 
warblers, or orioles, and more. Don't take Dave's word for it only, try 
it out yourself. Try using www.birdingonthe.net to browse this and many 
other lists including OBOL if you don' have too much free time and don't 
want to fill up your email inbox. I have doing it that way for years. It 
am subscribed to OBOL, but I have set my settings to "no-mail." In this 
way I can send messages to Obol, but do not receive any. I just read 
them on Siler's pages: www.birdingonthe.net. Easy.

Dave Iron's post frustrated me a bit because I found it to include too 
many assumptions on what the audience composed of the subscribers to 
OBOL want from the list. Not everyone is a beginner. Not everyone is an 
expert. Many are expert at some groups of birds and intermediate at 
others. When I was just starting out I wanted the hard quizzes and the 
challenges. My id skill quickly improved under the tutelage of experts 
like Jeff Gilligan, Owen Schmidt, Harry Nehls, and Dave Irons. If this 
had been easier I wouldn't be as good at birding as I am today. Any 
teacher worth her salt will tell you that asking for work on a problem 
for which there is no definite answer is not a waste of teaching. Much 
can be learned.

I consider Dave Irons to be a friend and I have know him and birded with 
him off and on for over twenty years now. We have often agreed on 
opinions at Oregon Birds Records Committee meetings where most of the 
other members have not. In this case though, I just can't sit back and 
let Dave dictate what is or isn't appropriate for OBOL, bird quizzes, or 
birding any more than I can with other members of this forum. I DO 
though welcome and appreciate Dave's thoughts and thank him for sharing 
his opinions.

I would recommend that if people like Chris want higher participation in 
their photos quizzes that they find a web page host where the @ symbol 
does not appear in the web address. You are probably cutting out more 
than half of your potential participants just by dint of having that @ 
symbol in the web address. Try blogger.com. I have used it with success.

Final thought: Why was the Red-throated Loon so easy to identify (it 
wasn't) compared to the gull in quiz 5?

Now, go birding. On Saturday 23 February there were three VIOLET-GREEN 
SWALLOWS flying high over the Mill Ponds in Seaside. Today there were 
SURFBIRDS, BLACK TURNSTONES, AND BLACK OYSTERCATCHERS at Arch Cape, 
Clatsop County.

Shalom,

David
