It arrives about the middle of May (12, 1875; 17, 1877), and spends 

 the summer. John Burroughs mentions 4 the occurrence of this spe- 

 cies at Highland Falls, and Giraud observes: 5 "the present species 

 has been shot during summer on the Catskill Mountains, and it is not 

 improbable that it breeds there ; it has been shot in Rockland County, 

 and other parts of the State of New York, but seems to be nowhere 

 abundant." At Riverdale, on the Hudson, Mr. E. P. Bicknell says 6 it 

 is "common during the summer, and regularly breeding." Dr. A. K. 

 Fisher has taken its eggs at Sing Sing, N. Y. It thus appears "that 

 the species is a summer resident along the Hudson, as far as Catskill. 

 Dimensions. Measurements of male: length, 4-85; stretch, 7*30; 

 wing, 2-46; tail, 1-90; bill from nostril, -35; tarsus, -66. Female: 

 length, 4-80; stretch, 7-24; wing, 2-25; tail, 1-77; bill from nostril, 

 35; gape, -55; tarsus, -68; middle toe, -38; its claw, '15. 



24. Helminthophaga chrysoptera, (Linns'). BLUE GOLDEN- 

 WINGED WARBLER. A summer resident. Arrives from the South 

 early in May (12, 1875; 10, 1878; 15, 1879). This species is a regular 

 spring migrant; and doubtless passes considerably farther to the 

 northward. The insect-like notes of this bird, once heard, are not 

 apt to be forgotten ; both it, and the preceding, are usually found in 

 swampy thickets. 



Dimensions. Average measurements of five specimens : length, 

 5-10; stretch, 8-05; wing, 2-46; tail, 1-94; bill from nostril, -34; gape, 

 67; tarsus, -70; middle toe, -42; its claw, '16. 



25. Helminthophaga ruflcap ilia, (Wilson). NASHVILLE WAR- 

 BLER. A very common spring and fall migrant, and rare summer resi- 

 dent. Arrives early in May (11, 1874; 11, 1875; 6, 1876; 13, 1877; 

 10, 1878; 8, 1879), departing late in September (21, 1874; 20, 1875; 16, 

 1876). In spring it is very abundant in fruit orchards, flitting among 

 the blossoms ; but in autumn, when it is abundant from the first to the 

 twentieth of September, it is usually seen skipping about in the tree 

 tops ; in summer it retreats to swampy wildernesses, there to breed. 

 I have not discovered its nest ; but Dr. Clinton L. Bagg has taken its 

 eggs at Poughkeepsie, on the Hudson. 



Dimensions. Average measurements of sixteen specimens : length, 

 4-77; stretch, 7-45; wing, 2-33; tail, 1-81; bill from nostril, -28; gape, 

 48 ; tarsus, '67. 



26. Helminthophaga celata, (Say). ORANGE-CROWNED WAR- 

 BLER. A rare migrant. "On May 13, 1875, I shot a beautiful male of 

 this rare species, as it was skipping among the apple blossoms, close
