BIRDS OF ARGENTINA, PARAGUAY, URUGUAY, AND CHILE 39 

 NOTHURA DARWINI MENDOZENSIS Chubb 



Nothnra danrini mcndozensis C. Chubb, Bull. Brit. Orn. Club, vol. 38, Dee. 

 12, 1917, p. 31. (Mendoza, Argentina.) 



No specimens of this tinamoii were preserved so that the alloca- 

 tion of field notes under this heading is provisional. Spotted tina- 

 mous of this type were recorded at General Roca, Territory of Rio 

 Negro, from November 23 to December 3, 1920, where the birds fre- 

 quented alfalfa fields and other green growth near the river. At 

 Victorica, Pampa, on December 28 I shot an immature bird, but was 

 forced to kill it at too close range because of bushes among which it 

 was found so that it was not possible to preser\'e it. It was light in 

 color and resembled mendozensis. Others were noted here between 

 December 26 and 29. The bird at times frequents open brushy areas 

 as well as fields and prairies, in this differing from the preceding 

 spotted tinamous. At Tunuyan, Mendoza, tinamou were fairly com- 

 mon from March 23 to 28 ; on the latter date I killed one but lost it in 

 high weeds. 



There is one specimen in the United States National Museum from 

 Cordoba (taken July 8, 1913, by Renato Sanzin) that differs from 

 specimens from Mendoza, the type locality, in more buffy coloration 

 and in possessing bolder markings above. 



In notes and general habits N. darwini is similar to N. m<icul-osa. 



NOTHOPROCTA CINERASCENS (Burmeister) 



Nothura cinerasccns Bukmeister, Journ. fiir Orn., vol. 8, 1860, p. 259. 

 (Tucuman.) 



An adult female about to lay was killed near Tapia in northern 

 Tucuman on April 10, 1921. These tinamou Avere fairly common 

 here in areas where thickets of small thorny shrubs grew in dense 

 clumps, interspersed with irregular openings covered with weeds 

 growing from 1 to 3 feet high. The call of males was a whistle sug- 

 gesting that of Calopezus elegans but far less musical. Though 

 heard frequently from April 6 to 14, they lay so close that only three 

 or four were seen during this period. They rise with a startling roar 

 of wings almost at one's feet and dash swiftly away, frequently giv- 

 ing a loud clucking call, dodging almost at once behind some clump 

 of brush that offers protection. I was forced to kill the one taken at 

 too close range, as it was about to disappear behind a bush, and 

 tore it badly. 



Tinamou heard whistling above the city of Mendoza on March 13 

 mdy have been the present species, as also one that flushed with an 

 excited note from a rocky hill slope near Potrerillos, Mendoza, on 

 March 19. 



Nothoprocta cinerascens is distinct from N. perdiccuria in having 

 coarser, larger reticulations on the posterior face of the tarsus.
