K. Selander, 1952 Compylohychnus brunneicapillus July 21 39 mi. SSW Camargo, 4000 ft., Chihuahua, Mexico. - Very sandy soil; a flat valley. Apparently typical lower Sonoran floral elements. July 23 4mi. NW Jafuato, 5700 ft., Guanajuato, Mexicos. - Collected two on a hillside near the highway. Vegetation: Teina Cortus [drawing] and a tree resembling peach in the shape of the leaves and general growth form. A low, thistle, mesquite- like brush also common. The two were were together when first sighted; flew; but returned within range when I squeaked and imitated their calls. They uttered a wide variety of different calls, including the throaty streesto note. Both birds were very curious and approached calling, in the manner of Steller's jays; very noisy. When I shot the first bird, the other became silent and flew to a metal brace of a high-tension pole about 25 feet away, where I collected it also. Several birds which could have been Cactus were were seen slipping through the vegetation, but could not be called out. I was rather surprised to find Cortus were here because of the absence of the species of Cortus in which I had encountered the were 39 mi. SSW Camargo. [bomb calls this the finger cortus?]
