Marshall (1942) Tyrannicus irissimus Chilata 2472 skel collected am one of a pair staying close together (same brush or sm tree) in the humid shaded gully where so many sp. made their only appearance at Chilata (ferns, springs, dense humid growth and under tall dense trees). Here were Todus assimilis, Catharus aurantiurostris, Ant-Wren, Y-gr Vireo, Blue Honey-Creeper etc. The pair pitched from brush to sm tree at edge of understory of forest with feeble flight like Gratecatchers. Stayed in outer foliage 10 ft up (but acted like Vireos & looked remarkably like them) ie moved around in foliage - did not stay on a single perch, looking for flying insect. There was nothing in my brief look into the behavior of this pair to suggest that they were flycatchers. 2505 taken at midday along creek on N side of range 1/2 mi before
