Chuck Aid raised the question of possible harm to "Flame Owls" in a note to CObirds on September 2.
That note and my response are below. I asked Dr. Brian Linkhart, FLOW expert at Colorado College to weigh in, and his note follows too.
Sept 2: message from Chuck Aid
The increase in recent Flam Owl sightings reinforces my feelings that it would be best not to report some sightings on eBird. Does this look like harassment to anyone else? I would appreciate the perspective of others.
Thanks,
Chuck Aid
Sept 2: reply from Joe Roller
As far as I can tell, the 2019 FLOW reports have not been from a single, certain nesting location,
but have been on roads going SE of Bailey toward Cheesman Lake, a large, vague area. So this seems
different for instance from a Spotted Owl Stake Out nesting site, which would attract many birders to a certain,
exact site, leading to probable harassment.
There is a lot of good Flammulated Owl habitat in those general areas of Jefferson County, so maybe eBird reports are not so bad.
Some very ethical, experienced birders have been among the birders posting this year.
Next, it seems better to me if field trips are made after the breeding season, instead of during it, perhaps minimizing harassment.
Colorado Bird Atlas II notes nesting dates of: May 25 (first occupied nest) to July 23 (last nest with young).
So mid to late August and early September checklists seem less problematic than ones in June and July.
And the ABA code of ethics pertain here, with obvious guidelines like:
a) not playing owl tapes til your batteries run low,
b) trying to get in and out of a small owl's neighborhood without dawdling, gawking, shining lights like Las Vegas
c) or trying for the 80th flash photo til "the crank of dawn".

Sept 23: opinion of Dr,. Brian Linkhart, Professor at Colorado College
Happy to weigh in on this, and I appreciate your contacting me about it, Joe.
Your comments are largely on target, so I'll only state a few additions to incorporate.
First, I'd expand the dates of the nesting season to go to Aug. 1, since we regularly have late nests (certainly this year) that don't fledge young until early August.
Otherwise your mid/late August timeline for conducting field trips is reasonable, as June and July are definitely problematic for conducting playbacks (this can cause females to abandon nests if within 100 m of playbacks, and it's very challenging to know with certainly if one is outside this radius).
Second, I'd limit total playback time to 15 min, as August and September are when males are establishing ownership of breeding territories (before they migrate), and extensive playback use may cause them to abandon their occupancy of the area. Thanks for your efforts to minimize human impacts on owls (and all birds). Any other questions, let me know.
Best,
