8. Marshall,1938 Otus flammeolus. Whitakers,contin. different place. Same alternation of calls. Seen by flashlight from rear; from front,in direct view,no eyeshine ,just large, dark eyes. At one time, hoot was higher & sounded like different bird.Several times changed to rushing sound,like night-hawk.Another bird present? As usual was in clump conifers encircling Black Oak. Finally shot - #413 male - as sat in crotch in Black Oak. Perhaps hooting occurs later laterin evening after feeding, therefore none heard at first locality! 2 hrs. after dark - about 9:30 Pm June 8 Same place as on 4th.(Above public camp grnd. 1/2 mi.N camp)In sunset light ,heard answer from tree at edge little wet meadow. Called 9-10 times then quiet.Resumed again later then again. In close,open-branched grove yuong cedars,saw ti it flit past - seen in flashlight. Flew swiftly thru trees & out & up at edge clump & swerve back to perch as if had caught am a flying insect. (Large moths & other fly- ing insects* abundant.) Then flew back to inter- interior, stopping instant at two perches,but keeping on the move as if following insect. Hence, explanation of always being high upp Too small & week-footed to catdh mammals,but strong wings te & rapid flight, darting flight for pursuing insects. Walked 200 yd. to stream where seen on 4th.Another there .Couldn't approach - didn't give double call,so couldn't tell if same bird. Went back & found lst. in c elump dense, streamside clump where seen on 4th and only 25 yd from meadow.Same 4-syll. call as the bird seen there on 4th. Two within 200 yd. Bright , clear;gibbous moon; calm. June 10 Same locality 1 1/8 mi. S camp on 5500 ft. contour, as on June third. Cloudy, dark evening.Still very light al- though a very cloudy day.One called 75 yd. S stream ( first stream S south bend in highway between camp & Sequoia ranger station).
