 blue-and-yellow macaws flew over this camp. They were 

 plentiful enough to form a loose flock, but each pair kept 

 to itself, the two individuals always close together and 

 always separated from the rest. Although not an abun-

 them save in technical language. Finally, among these 

 unfamiliar forms was a veery, and the sight of the rufous-

 rolling stretches of low forest. Midway on our journey 

 we crossed a brook. The dogs minded the heat much. 

 They continually ran off" to one side, lay down in a shady
