LITTLE BLUE HERON. 55 



(Oates) ; Jamaica, June 3 to July 8, 1890 (Field) ; Cuba, May to July 

 (Gundlach) ; Alachua County, Fla., April 8, 1890 (Pearson) ; Tar- 

 pon Springs, Fla., August 26, 1886 (Scott) ; Charleston, S. C, April 

 7, 1910, much earlier than usual (Wayne) ; Avery Island, La., May 

 4, 1895 (Knight) ; Corpus Christi, Tex., June 12, 1884 (specimens in 

 U. S. National Museum). 



Winter range. — This species remains in winter throughout the 

 larger part of its coastal breeding range in the United States, stay- 

 ing north regularly and commonly as far as Charleston, S. C. 

 (Wayne), and a few on Currituck Sound (McAtee). It is not rare 

 in winter on the coasts of Louisiana and Texas (McAtee), though 

 the larger part of the breeding birds in all the above-mentioned 

 places retire farther south for the winter. The winter range on the 

 Pacific coast of Mexico includes the district north to Ocotlan, Jalisco 

 (Goldman), and to Mazatlan, Sinaloa (Lawrence). 



Spring migration. — The arrival of the species in the spring was 

 noted at Whitfield, Fla., March 21, 1903 (Worthington) ; Chipley, 

 Fla., March 12, 1903 (Pleas); Cumberland, Ga., March 8, 1902 

 (Helme) ; Frogmore, S. C, average of four years March 31, earliest 

 March 22, 1886 (Hoxie) ; New Orleans, La., average March 13, 

 earliest March 11, 1894 (Beyer) ; Bay St. Louis, Miss., March 13, 

 1902 (Allison) ; St. Louis, Mo., April 30, 1880 (Hurter) ; and Bick- 

 nell, Ind., April 18, 1896 (Chansler). 



The last two dates, taken in connection with several others already 

 given, show that a few little blue herons migrate or wander north in 

 the spring beyond the normal breeding range, but there are no dates 

 to indicate that such birds remain the rest of the summer in the 

 north as nonbreeders, and probably they soon return southward. 



The birds of the southern part of the range have been separated 

 as the subspecies ccerulescens (Latham), which includes all of South 

 America and parts of the Antilles and Central America. The divid- 

 ing line between these two forms is not yet definitely known. 



[Zeledon Boatbill. Cochlearius zeledoni (Ridgway). 



The Zeledon boatbill occupies nearly the whole of Mexico and Central Amer- 

 ica from Sinaloa (Mazatlan), Tamaulipas (Alta Mira), and Yucatan (Cdzumel 

 Island), south and east to Porto Bello, Panama (Goldman).] 



[Pileated Heron. Pilherodius pileatus (Boddaert). 



This heron is a South American species that was once taken 50 years ago 

 along the line of the Panama Railroad (Lawrence). Since it has not been 

 noted by the many collectors who have visited Panama in the last few years, 

 it is probably now extinct in that country. The range in South America ex- 

 tends south to Peru (Pebas, Santa Cruz, and Nauta) and to Sao Paulo, Brazil.]
