FKINGILLID.E — THE FINCHES. 569 



The food of this bird, in Lda-jidor, was found to consist of sm.aU coleop- 

 terous insects, grass-seeds, a variety of berries, as well as minute shell-tish, 

 for which tliev searched the niarj'ins of i)onds near tlu^ sea-shore. Thev 

 were also seen to pursue insects on the wing. Mr. Audubon speaks of its 

 song as consisting of six or seven notes, and describes it as loud, clear, and 

 musical, although of a plaintive nature, diminishing in power to the last note. 

 Its flight he describes as low, swift, and protracted. 



Dr. (.'oues did not tind this bird abundant in South Carolina during the 

 winter, and conjectures that it does not go so far to the south. Its migrsitions 

 do not appear to be well detin(Ml, and nowhere is it known to be abundant 

 during this season. Lieutenant Couch met with it at Brownville, Te.xas, and 

 Tamaulipes, Mexico, and at Charco Escondido, in March, at whicli time they 

 were in flocks, indicating a more southern migration than is generally sup- 

 posed. 



It extends its northern migrations to the extreme northern and northeast- 

 ern portions of the continent, and also to Greenland. On the Yukon and 

 Anderson Rivers it is r»'placed by the Z. (imnheli It is not abundant in 

 Greenland. Holbidl obtained a single specimen only in August, and after- 

 wards met with a flock of young- birds.- He infers that they breed in the 

 interior, but are restricted to a very narrow strip of territory. 



Eggs of this species, from AVyoming Territory, measure from .00 to .05 of 

 an inch in length by .70 in breadth, and are of an oblong-oval shape. The 

 ground-color is a light greenish-white, thickly marked with reddish-brown 

 and lighter markings of an obscure purplish-brown. The intensity, depth of 

 coloring, and size of the darker brown markings, vary. They are princi- 

 pally disposed about the larger end.

Sp. Char. Precisely similar to Z. leucophrys. but rather smaller; the lores are gray 

 throughout, this color continuous with a white superciliary stripe along the side of the 

 head. Length, 6.25 ; wing, 2.83 ; tail, 3.08. 



IIab. Rocky Mountains to the Pacific coast, north to Nulato and Fort Kenai, east 

 through the valley of the Mackenzie River, and south to Jalisco and Mazatlan, Mexico. 



As stated in the previous article, the only appreciable and constant differ- 

 ence between this race and Z. leucophrys is found in the character of the 

 black stripe on the side of the crown. Tn Icacophrys the black passes down
