I came down to the brook and then upstream about 75 yards to where I heard Atrornes calls. Scolding birds were in oaks on S face on either side of a shallow recess chuk dub dut vehement on both sides. I tried to see the bird to W (I thought 1 there, 2 E) and that bird retreated to W - then E bird (neither scolding bird seen) started to sing peer ---- I endeavored to follow W bird (silence except for that song at 8:42) I heard Atrornes 25 yds W in brookside trees and saw courtship feeding twice within the minute after 8:45. (to investigate upstream pair) I started up canyon and heard song & scold simultaneously from N slope opposite scene of squabble - then scold from W and a melee involving four birds in low oak brush with vehement scolds but no song. This at 8:49. I proceeded downstream but heard no Atrornes on S side Song from up canyon at 8:55, then silence. The bawdry dispute between those two pairs really occurred on the next hill E of ridge E of plowed field. Vegetation largely Spanish oak, the juniper where present cleared out for most part.
