earlier in the day, it flew down from a similar sort of hillside into the twine below. Chirpas Several Greater Blue Herons were seen about the margin of the grassy area. Although the peak was devoid of bird life. In the canyon there were several Plantain Eaters. They were giving their queer croak quite frequently. I collected a group of three jir, (an Tail Warblers) just shortly out of the nest. This proves the spelling of the species in the lower country. 3 more adults were scarce, all running true to form with yellow chips. The altitude of the peak was about 2100', the Roadrunner nest 1600 and the canyon near where the young Warbler were found, 7-900', (according to Van's barometer). The boatman finally brought me a Thrush. They certainly are pretty built. The bird was a male at the height of building.
