70 NOKTH AMERICAN WAEBLEES. 



the northern part, where it has not been found by any of the explorers 

 who have made such larg-e collections in the Santa Marta region. It 

 has been taken at Medellin ^' in the mountains of central Colombia at 

 6,000 feet; at Bogota; ^ and there are specimens in the British Museum 

 from the interior of Colombia and Antioquia. 



It is not probable that the cerulean warbler winters north of Panama, 

 but there are a few records of the species during the migrations. It 

 was seen four times during the fall migration at San Jose,^ Costa Rica; 

 it was once taken at San Pedro '^ in northwestern Honduras, once by 

 Gundlach in April in Cuba,^ and once on the island of Grand Cayman,/ 

 and one struck the lighthouse at Cay Lobos,^ Bahamas, April 26, 1901. 

 There is no Nicaragua record. The only records between Honduras 

 and Texas are of Deppe's^^ specimens, said to have been taken in Mexico; 

 Schott's record for Yucatan,^ and those of the two specimens noted by 

 Baird,-^* one as being in the cabinet of Lawrence and coming from 

 Guatemala, the other one of Yerreaux's birds, labeled "Coban, Guate- 

 mala." This species was not seen by any of the parties whose work 

 formed the basis of the Biologia Central i- Americana, nor has it been 

 noted in Mexico b}^ any of the parties of the Biological Survey. 



Spmig migration. — There is but one March record of the cerulean 

 warbler in the United States, and this is of one taken on the 23d of 

 the month in 1890 at the Tortugas. The spring records of the bird 

 at Eubank, Ky . , cover a period of eight 3xars. The average date of 

 the first bird seen is April 13; date of second seen, April 11; date when 

 birds were common, April 20; extreme dates of first arrival, April 5, 

 1892, and April 21, 1895. The earliest date for the species in Chester 

 County, S. C, is April 13, while at St. Louis the aAxrage date of arrival 

 is April 15. Other records of average date of first seen are: Brook- 

 ville, Ind., April 27; Beaver, Pa., Ma}^ 1; Petersburg, Mich., May 2, 

 and southern Ontario, Maj^ 7. In 1902 the first bird was reported 

 from North Freedom, Wis., May 1, and in 1887 from Lanesboro, 

 Minn., May 5. These dates seem to determine quite closely the time 

 of arrival of the earliest birds at their breeding grounds, but there 

 are no corresponding dates for the Gulf Coast. The dates for Key 

 West, Fla., are April 16, 1887, and April 29, 1889; for New Orleans, 

 April 8, 1898, and April 10, 1899. All the Texas records of first
