R. K. Selander, 1954 March 12 4mi. WSW Jimenez, Chih. to 5mi. SE Nombre de Dios, 6200ft., Durango, Mexico. - Skinned two desert sparrows before breaking camp. Heard three or more cactus wrens calling around camp and saw several nests but no birds. Toxostoma curvirostre noted near camp. Apparently wrens are present in the area but wind causes them to keep out of sight. Continued on to Hidalgo de Parra] where we had coffee. Between Hidalgo de Parral and El Entroque (or Zarea, 6068ft., on road map of Texas) there is no cactus wren habitat. A very dry region with low scrub vegetation in the lower parts and oaks (?) and junipers on the higher ground. As far in either direction from the road as I could see there was no vegetation suitable for wrens and there must be a considerable gap in the range here. At El Entroque the vegetation is similar to that at Jimenez with a few scattered cholla and thorny bushes, south of there the road climbs into the hills where there is a good growth of Ocotillo, yucca (large, tree-like), cholla, and thorny brushes and brush-trees — all in all good cactus wren habitat. 12 mi. N by road from the point where the highway crosses the Rio Nazas, +6000ft., we stopped for lunch and took two color photos - one showing a tall yucca in flower and the other a close-up of a cactus wren nest in a cholla. Heard wrens calling while we were eating.
