KENTUCKY WARBLER 511 



"Arriving in September, the Kentucky warbler spreads over the 

 length of Central America, including the lowlands of both coasts, 

 wherever suitably humid conditions prevail, and winters at altitudes 

 up to 3,500 or perhaps 4,000 feet above sea-level. It appears to de- 

 part early; until the present year I had only two records as late as 

 April, one for the third and the other for the twelfth of the month. 

 But this year, 1943, it was for a brief period in late March and early 

 April rather abundant in the forests of this region of southern Costa 

 Rica ; and I saw it repeatedly until April 9. 



"Early dates of fall arrival in Central America are: Guatemala — 

 Chimoxan (Griscom), September 13, Honduras — Tela, September 

 11, 1930. Costa Rica — San Jose (Cherrie), October 7; Rio Sicsola 

 (Carriker), September 21; Basin of El General, October 8, 1936, and 

 October 12, 1942. 



"Late dates of spring departure are: Panama — Barro Colorado 

 Island, Canal Zone, March 28, 1935. Costa Rica — Basin of El Gen- 

 eral, April 3, 1936, February 26, 1937, March 11, 1939, April 12, 1940, 

 February 23, 1942, April 9, 1943."
