[obol] no BOOW at Crater Lake

[Alan Contreras]

BOGR is the informal way people refer to Birds of Oregon: a General Reference.

It does sound like a bird, though.  Booted Grouse? Boreal Grosbeak? Bollinger's Grampus (no, sorry, that's a whale.)

>Hi OBOL,
>I found myself at Crater Lake NP Oct 13-15 and made a try for Boreal Owl in 
>the hemlock forests from the 7100 ft rim down to the headquarters area.
>No luck. I played boow toots and other vocs from the new Cornell CD at each 
>of 8 stops in the moonlit predawn and again at about 5 of the same stops at 
>very late twilight and afterward of the same calendar day (Oct 14, 2006). I 
>also played nswo toots at several of these stops. Conditions were ideal, 
>with little wind or automobile noise, and air temp. above 40F. I got two 
>responses, possibly from the same bird. A strong response around 4:50 am 
>consisted of about six piercing whistles, three of which I was able to 
>record. They are very similar to the "Whine-like call" recorded by Kevin 
>Colver in Utah, BLB 28001, which is cut 63 on disc 2 of Cornell's new Voices 
>of North American Owls. The Utah recording and mine are shorter in duration 
>than the Whine on cut 64 of the Cornell set, and the whine pictured as Fig. 
>3B in the print BNA, so I suppose the exact designation of this call remains 
>in doubt. The other response was three fast descending calls, not recorded, 
>which sounded to me more like the ksew calls on cut 64 (NSWO) than the BOOW 
>skiew call on cut 56.

>Although BOGR lists no records as far south in Oregon as Crater Lake, this 
>still seems like good habitat (Mountain Hemlock at 7000' with openings). The 
>south entrance and the road to the rim of Crater Lake are kept open all 
>winter, so I may be back in Feb. or March to listen for singing males.

>Good owling, and thanks to the Broken Top crew for inspiring me to try this.
