Marshall (1942) Tanagra lanta Chilata Call similar to Western Wood Pewee but Call a high whistle like canary downward inflected but not rough like W. woodpewee. Found only in trees on wall of dep rocky gorge where Colored swifts found. Same place 2 different days got one each time. Only 2 or 3 birds seen. Looked and acted like green-backed goldfinch. I think I found them when they were coming down to stream to drink. Saw at very close range. Tanagra affinis Lake Olwega Common, paired in larger dense trees along road thru fields W camp. All within 300 yds camp. after that tree small & scraggly. Were 6+ pairs. It was several weeks before I shot one and was surprised to find it wasn't a green-backed goldfinch. high Mount Calls, size, pattern, color, shape all identical in field views. Usually in highest parts of tree but once or twice a few ft. from ground on fence and adjacent mesquite beneath the tree. rarely Chilata Pairs occasionally heard or seen. In shot or road inland side of range. 1 pr. on hill across canyon from camp.
