This in area where trees & shrubs form almost (in places completely) completely closed canopy. & dropped down into subcanopy of tree 40 feet to N. Other forloused. & then worked rapidly to top of tree when sang - ..... once. ? (other bird) gave short chatter (pit-za pit-za). & picked up larva after finishing singing & ate it while I worked to top of same tree. & then dropped down & out of sight. I over to next tree when worked in canopy - mostly on bare portions of branches + running into foliage. (8-10' up). Almost out to flip of some branches. 0900-0930. watched pair foraging in some closed canopy area as at 0835. Probably the same pair although had moved to S along hillside. Foraged thru all layers from 1-2 feet above ground to 10+ put up. Mostly on bare portions of branches + pecking at foliage. &e cling to a vertical vine - antlike fashion - + peck at undersides of leaves then dropped back to horizontal branch. Caught two caterpillars in succession - one 3/4"t & the other 1"t. Smaller one eaten right after catching & with no preparation. For larger bird dropped down to bare limb (1"dia.)not apparently different from trunk from which caught (larva). Then flicked head from side to side with larva hanging from bill. Tewed to bit larva against limb, but not sure. Then ran larva thru bill once + swallowed.
