[[left margin in purple]] I N [[/left margin]] [[left margin in green]] 2 I NHO 3 [[/left margin]] Come across mixed flock almost immediately. Includes at least 1 [[one green checkmark, one blue checkmark]] PL Atlapetes, several [[2 pencil checkmarks, 2 green checkmarks, 2 blue checkmarks]] other birds. [[left margin in red]] 1 [[/left margin]] 8:15. See single PL [[1 red, 1 pencil, 1 blue checkmark]] [[circled in blue]] 1 [[/circled]] Atlapetes (possibly same bird as before). By itself. Silent. In low open scrub. It is suddenly supplanted (definitely attack) by one of the local hummers. [[left margin in red]] 2 [[/left margin]] The "White throat". (no. I on list Merida hummers). Moves off without resistance. Everything [[underlined]] very [[/underlined]] quiet 8:25 am Lots of thrushes around here. Fairly light grayish brown. Orange bill, feet, and eye ring. In pairs.
