Winter visitor from the north. Rare. This species was not known 

 from Panama before 1965. The normal winter range is south to Hon- 

 duras and northeastern Nicaragua. It is found more rarely to Costa 

 Rica. On March 15, 1965, a male was collected by Dr. A. Diaz near 

 Tocumen, on the Pacific slope about 32 km east of Panama City, Prov- 

 ince of Panama. The specimen is now in the Smithsonian. Hicks et al. 

 (Condor, 1967, p. 319) erroneously list the date as October 14. Other 

 sight records led Ridgely (1976, p. 297) to describe the Palm Warbler 

 as "a rare but probably regular winter visitor in small numbers on 

 Caribbean slope of Canal Zone and savannas of eastern Panama Prov- 

 ince . . . mid-November-mid-March . . . usually on or very near the 

 ground. In Canal Zone, prefers lawns in residential areas."

 Reinita de la Pradera 



Sylvia discolor Vieillot, 1808 or 1809, Hist. Nat. Ois. Amer. Sept., 2 (1807), p. 37, 

 pi. 98. (United States and Greater Antilles.) 



This species is included on the basis of a sight report of 1 at Volcan, 

 Chiriqui on January 23, 1973, found by Richard Brownstein and Wal- 

 ter George. Brownstein (in litt. to Wetmore, June 25, 1974) informs 

 me that they observed the bird for 10 minutes as close as 7 m; they did 

 not, however, supply any details of plumage. The Prairie Warbler 

 normally winters in Florida, the West Indies, and, in very small num- 

 bers, from Yucatan to Nicaragua, mainly on islands off the Caribbean 

 coast, and on islands off the north coast of South America. There are 

 also some recent sight reports from Costa Rica (Stiles and Smith, 

 Brenezia, vol. 17, 1980, p. 15).]
