14. Behavior of bird / circumstances of observation:

 

Robby and I kept flushing this bird, but I was unable to get close enough to it when landed to observe it.After about an hour, I located it in the open and observed it through a scope.Bird typically glided as much as possible and stayed below canopy level.Bird shaped somewhat like Merlin in flight.

 

15. Description: (I inadvertently copied over an earlier version of this report, and my memory is not fresh on it, so Iím simply transcribing the field notes from the recording of that day.) Center of throat white, sides of throat mottled buff and slightly darker brown.Cutthroat white pattern, so white throat patch an inverted T or V or Y.Eyelid manila.Crown speckled grayish on the sides, with perhaps a darker central crown stripe or patch. Very fine bracket-shaped markings on the lower breast, upper breast mottled or perhaps with barring bunched up.Ground color of underparts pale manila, barring dark brown.Lesser coverts dark brown, with small pale buff tips or dots, wider on the bend of the wing, median coverts a mottled grayóresembling juvenile feather pattern.Single pale buff spot on greater(?) coverts, a few rows of buff proximal to the white stripe on the primaries.White alula. Wings reach to about tail tip. Primaries medium brownish, a worn color.Auriculars have kind of buffy color, mixed with black.
