124 NORTH AMERICAN WARBLERS. 



at Alta Mira/^ and another was noted at Taniaulipas November 20, 

 1894. The parties of the Biological Surve}^ took a specimen at Mot- 

 zorongo, Vera Cruz, in the spring of 1891 and another at Alta Mira in 

 April, 1898. Long previous to these dates Salle and Sumichrast 

 recorded the bird from Cordoba and Orizaba, Vera Cruz. The species 

 is not uncommon in winter in Yucatan, and during the spring migra- 

 tion is abundant both there and in Tabasco and Campeche. It occurs 

 in winter over most of Guatemala from sea level to about 5,000 feet. 

 Apparenth^ the onh^ record of its occurrence on the Pacilic side of mid- 

 dle America is at Retalhuleu in southwestern Guatemala. It is a not 

 uncommon winter resident of the islands off the east coast of Yucatan. 

 It has been taken in September on the islands of Ruatan and Bonacca* 

 off the coast of Honduras, on the mainland at Truxillo,'" and in central 

 Honduras at Comayagua (3,000 feet). From September to February 

 it is an abundant winter resident along the coast of southeast Nicara- 

 gua,^^ and is probabh" more common in Costa Rica than the single rec- 

 ord for that country would indicate. Several specimens have been 

 taken on the Atlantic coast of Panama, but it has not been traced as 

 3^et to the mainland of South America. It is thus seen that in winter 

 the hooded warbler is principally a bird of the heavy forests along the 

 coast, with a few individuals penetrating to the forests of the interior 

 nd up to an altitude of nearly 5,000 feet. 



Spring migration.- — The main migration route of the hooded warbler 

 m spring is from southern Mexico to Louisiana, The species arrives 

 no earlier in Louisiana than in Florida or Texas. The average date 

 of arrival in northern Florida is March 28; at New Orleans, March 25, 

 and in central-eastern Texas, March 22. This is a closer agreement in 

 time of arrival at the three localities than has been found in the case 

 of any other migrant. Some closely agreeing Florida dates in 1885 

 are: Perdido Light, March 19; Pensacola, March 21, and Palatka, 

 March 23. The extremes of arrival in Florida are March 18, 1887, and 

 April 2, 1881; at New Orleans, March 8, 1896, and March 31, 1901; 

 and in Texas, March 13, 1899, both at Corpus Christi and in Refugio 

 County, and March 31, 1890, at San Antonio. 



Following the Florida route northward, the first hooded warblers 

 seen in 1885 were noted on April 5 at Savannah, Ga. , and on the same 

 date also at Rising Fawn, diagonally across the State, in the extreme 

 northwestern part. The average date of arrival for eight years at 

 Kirkwood, Ga., is April 10, with extremes of April 6, 1897, and April 

 15, 1899 — the least variation in arrival of any of the species reported 

 from this place. The first hooded warblers to arrive in 1885 at Frog-
