Most of them were foraging in foliage + on smaller branches of the conifers; and at a small water-filled hole (40+ feet x 60+ ft.) in middle of the forest there was a regular trooping of small birds down to the waters edge for drinking + bathing. 5 or 6 of this sp. were involved, all of them moving in a circuitous route thru forest to go to the water via a dead tree top which extended from forest into the water, slooly avoiding the 30+ ft. wide opening elsewhere.
