LLW815 1963 Aimophila quinquestrata July 14 saw 1 card Canyon Wren near position #1, along crest of hill over series of rock outcrops. In 3/2 minutes watching a pair - one of birds earlier seen just uphill, led by long gray rectrix - foraging on north hill (south facing) They spent half or more of their time in the small trees (up to 5-6 feet) In "subcanopy" where [illegible] limbs + some foliage. Progress by hopping from branch to branch perching at surrounding foliage. Did not see any captures. Also some time on ground. These birds alternated the 2 substrates, but greater 70% time in shrub layer. Did not restrict to one species of tree & did not only choose legumes. Also forage on fallen dead shrub layer vegetation. 0835 - bird flew from crest to land in top of 40 foot decid gully. Just below landing (only time seen) flight was very floppy. Bird tail at tail cocked [illegible] well above horizontal. Maintained this with feathers fluffed for 30+ sec. Then gradually tail lowered & body smoothed, probably an alarm reaction. 0837 - bird singing from crest. Another just below crest in subcanopy of 8 foot legume. This second bird giving tzeeb, & chug notes while first was singing. Singer left & was followed 30 min later by 2nd bird.
