Carriker : List of the Birds of Costa Rica. 911 



Salvin and Godman's remarks (Biologia) it is likely that their birds from 

 Guatemala were also of this form, although the most recent record from 

 that country (Dearborn, Field Mus. Nat. Hist., Orn. Series, I, 1907, 116) 

 is given as C. s. bimaculatus — based however on March specimens, which 

 may have been migrants. At any rate it seems probable that the range 

 of the present form is practically continuous from southern Mexico to 

 northwestern Costa Rica, and it should be looked for in suitable situations 

 in the intervening region." (W. E. C. Todd.) 



The specimens above referred to were taken on the grassy slopes of 

 Miravalles and were unquestionably breeding and resident birds. They 

 were fairly abundant, and very likely breeding at that time, the females 

 being incubating, which would account for the small number of that sex 

 taken. All Costa Rican records should be referred to this form and not 

 to the northern bird as a migrant, which I do not believe reaches nearly 

 so far south as Costa Rica. The species is almost wholly confined to the 

 higher grass-lands of Guanacaste, rarely straggling up into the interior, 

 as seen by the records of Frantzius (San Isidro and Guadeloupe).

"Several specimens of the series of nineteen birds collected at Paso 

 Real and Buenos Aires de Terraba show a touch of clay-color on the ab- 

 domen. Some variation also exists in the amount of streaking on the 

 sides. 



"This form is most nearly related to E. s. hypochondriacus Hellmayr, 

 from Chiriqui, to which Mr. Bangs referred a series from the same general 

 region where Mr. Carriker later obtained his birds. No form of this 

 species has as yet been found between Chiriqui and the Santa Marta region 

 of Colombia." (W. E. C. Todd.) 



I took first four males near Paso Real on August 5, where it was very 

 rare and hard to shoot. Later I found it abundant on the large "sabana" 

 east of Buenos Aires. During the heat of the day the birds are scarcely
