Family REGULIDAE 



REGULUS SATRAPA AZTECUS Lawrence 



Regulus satrapa aztecus Lawkence, Ann. New York Acad. Sci., vol. 4, June 1887, 

 p. 66 (City of Mexico). 



During my work at Sierra Santa Elena I watched and listened con- 

 stantly for this tiny bird, until, on November 21, 1 secured a fine male 

 at 9,500 feet elevation. At Desconsuelo at 10,200 feet on November 

 24 I saw a number in the tall pines and shot a female. Most of them 

 were so high in the trees that they were out of range, and were very 

 difficult to follow because of their size. In actions and in notes they 

 appeared to me identical with the two northern forms, but their darker 

 color is easily evident. There are two additional males in the 

 National Museum taken by E. W. Nelson and E. A. Goldman at Todos 

 Santos, Huehuetenango, December 28, 1895. 



While currently known under the subspecific name clarus ^^ this 

 race must be called aztecus as indicated above. Nelson ^* considered 

 the type of aztecus as merely a winter migrant of Regulus s. olivaceus. 

 And Dearborn in his description of clarus said that he had seen this 

 same type and also called it olivaceus. Hellmayr ^^ has expressed 

 doubt in the matter and recently I have compared this type again to 

 find that it is undoubtedly identical with the Guatemalan bird. 

 Lawrence's name must therefore replace clarus. The type (Amer. 

 Mus. Nat. Hist. No. 39341) is a male marked "City of Mexico" with 

 no date but is a bird in fresh plumage taken probably in fall or 

 winter. It is distinctly darker in dorsal color than olivaceus. 



There are specimens of aztecus in the U. S. National Museum from 

 Ajusco and Salazar, Distrito Federal, and from Parada, Oaxaca. 

 The name aztecus was published also by Ridgway ^'^ and attributed to 

 Lawrence.

 (Quetzaltenango, 8,500 feet elevation, Guatemala). 



On November 24 I shot an adult male in low bushes at 10,200 feet 

 elevation at Desconsuelo. The eye was brown.
