HAB. Eastern North America, breeding from northern border of United States (in- 

 cluding higher portion of Middle States), northward. Winters in Mexico, Central 

 America, and northern South America to Ecuador. 



"Sp. CHAB. Upper part bluish ash ; a ring around the eye, with a line running to the 

 nostrils, and the whole under part (except the tail-coverts, which are white), bright yel- 

 low. Centres of the feathers in the anterior half of the crown, the cheeks, continuous 

 with a line on the side of the neck to the breast, and a series of spots across the forepart 

 of the breast, black. Tail-feathers unspotted. Female similar, with the black of the 

 head and breast less distinct. In the young obsolete. Length, 5.34; wing, 2.67; tail, 2.50." 

 (Hist. N. Am. J3.) 



"First plumage. Female. Remiges.rectrices, etc., similar to the adults. Rest of the 

 upper parts, including wing-coverts and sides of head, uniform deep dull cinnamon ; the 

 greater coverts tipped with fulvous. Throat, breast, and sides very light cinnamon, 

 tinged with olive. Anal and abdominal regions pale sulphur- yellow. No conspicuous 

 spots, stripes, or markings anywhere. (From a specimen in my collection shot at Upton, 

 Me., August 4, 1874. This bird was so young as to be scarcely able to fly, and with the rest 

 of the brood, was attended by the female parent.) 



"Adult in autumn. Male. Similar to adult in spring, but with the yellow of the under 

 parts much more intense, and the black spotting on the breast slightly clouded by the 

 yellow tipping of the overlapping feathers. (From a specimen in my collection shot at 

 Upton. Me.. August 29.1874.) 



" Young in autumn. Male. Pileum and back greenish olive; nape and rump bluish 

 ash, slightly tinged with olive. Centres of a few feathers on the forehead and cheeks, 

 with a continuous line along the side of the neck to the breast, dusky- black. A broad 

 band of very small spots (each one not more than one Quarter of the size of those ex- 

 hibited in the adult plumage) across the upper part of the breast black. Otherwise 

 similar to the adult." (BBEWSTEB.-BuZZ. Nutt. Orn. Club, Apr. 1878. pp. 60.61.) 



This handsome species is rather a common migrant, being in 

 fact, sometimes one of the most abundant members of the family. 

 It has not yet been detected as a summer resident of any part of our 

 State, but, since it is said to breed "in New York and Massachu- 

 setts, and in the region north of latitude 42" (BREWER), it very 

 likely does so in the extreme northern portion of Illinois.
