FAMILY FRINGILLIDAE

grasses. They were feeding on seed heads by flying up and alighting on 

 them to bend them down. The males were in full breeding condition 

 and the one female I collected had recently laid. Their call was a low 

 churring note. Ridgely ( 1976, p. 336) describes a song of the males as 

 "a thin buzzy trill, at times somewhat musical, delivered from an ex- 

 posed perch, sometimes in flight." 



This species was first recorded in Panama through a sight observa- 

 tion late in January 1951 by Dr. R. T. Scholes, who noted it at two 

 localities between Rio Hato and Penonome, and recognized that it was 

 unknown. Eugene Eisenmann and John Bull, in July 1952, found it 

 fairly common, several small colonies being located. In crossing this 

 area in May 1953, I collected 1 near Anton, and later, on June 20, I 

 secured the rest of the series from which the description was written. 

 On the June excursion, I had the pleasure of the company of Mr. Eisen- 

 mann, in whose honor the race is named, in recognition of his studies 

 of Panamanian birds.
