THE IPSWICH SPARROW. 33 



'iou7tg of the year. Differs from the adult in the brownish, rather than grayish, 

 tints above, in the richer, deeper russet on the wings, and in the decided buffy wash 

 that suffuses the head, the neck, and the under parts. This buffiness is most 

 marked on the sides and breast, and it strongly tinges the malar stripe and auriculars. 

 Young in first plumage. {$ , juv., No. 3870, collection of J. Dwight, Jr., Sable 

 Island, Nova Scotia, August 25, 1894.) Top of head, neck and rump, yellowish 

 buff, tinged with ochraceous, and streaked narrowly with deep clove brown. An 

 indistinct median stripe on the crown is pale buff. Back and upper tail coverts 

 buffy or ashy, broadly striped with deep clove brown. Each feather has a large 

 median, almost black, elliptical spot that merges into a narrow zone of buff broadly 

 edged with ashy white. The scapularies are partly edged with vandyke instead of 

 buff, thus producing two lateral brown stripes. Quill-feathers of the wings and 

 tail, clove brown, edged, chiefly on the outer webs, with pale cinnamon brown which 

 becomes broader and richer on the long tertiaries, while the margins of the first 

 primary, the short tertiaries, and the greater and median coverts, are conspicuously ashy 

 white, forming on the coverts two obscure wing-bars. The median coverts are 

 dusky and show little or no cinnamon. Beneath, pale yellowish buff, nearly white 

 on chin, abdomen, and under tail coverts ; streaked, as in the adult, on the sides 

 and breast with deep clove brown, almost black. Rictal and postocular streaks 

 strongly tinged with vandyke. Auriculars pale ochraceous buff, forming a distinct 

 spot on the side of the head ; lores dusky. Superciliary stripe ashy gray. Tibial 

 pale cinnamon. Legs, feet, and bill similar to those of the adult, but somewhat paler. 



The relatively larger size and paler coloration of this species readily distinguish 

 it in all plumages from A. sandwichensis savanna, the average female being about the 

 size of the male savanna. The superficial resemblance to certain pale Western birds 

 referable to A. s. alaudinus, is in a few cases rather striking. The first plumage of 

 savanna is everywhere darker than that of princeps, having a deep ochraceous 

 instead of a buffy cast, while the margins of the tertiaries and secondaries are a 

 deep cinnamon, almost chestnut, and the streakings are somewhat heavier.
