to a group of wrens near the tent. She had first heard the wrens at 9:15 and had found them in
a tall pine tree - a pair together there and a lone bird in an oak tree adjacent to the pine. The pair would duet and the other would sing rather independently of the pair. They flew towards the road, crossed the road (a flight of ±100yds) and into large trees (pines and the yellow-leafed tree). At one time the lone bird perched on the top twig of the pine (40 feet) and sang (she doesn't recall the song). After singing it flew back across the road to the big trees 50y of the tent. The junipers were used as landing perches in the longer flights and they did remain long in them. Feeding occurred high in the big yellow trees on the smaller branches at bases of clusters of leaves. Later another pair joined the group in trees 50y of camp - then the party worked rapidly down the canyon west of camp. At this point I arrived - in a few minutes three birds appeared in the trees just west of the tent. I shot one bird which and then collected a pair which were perched together.
The warning note is a slit-slaw given rapidly. This heard after I shot the first bird, The birds taken today were not breeding - no brood patch on female - but tents are fairly large.
