Passerella iliaca (Merr.). Fox Sparrow 



1. Natal Down. No specimen seen. 



2. Juvenal Plumage acquired no doubt by a complete post- 

 natal moult. I have been unable to obtain any specimens at 

 this stage, but judging by P. iliaca iinalascheiisis the plumage 

 probably resembles the first winter dress, being browner with 

 paler edgings and more streaks above, and darker with heavier 

 dusky streaking below. The wings and tail (as seen in the next 

 plumage) are clove-brown with walnut-brown edgings, the wing 

 coverts probabh' with more buff than in first winter plumage. 



3. First Winter Plumage acquired by a partial postjuvenal 



moult which invoh'es the bod\' plumage and wing coverts but 



not the rest of the wings nor the tail. 



Above, olive-brown, streaked broadly with burnt-umber, the wing coverts walnut- 

 brown, darker on inner webs and tipped faintly with pale buff. Below white, 

 the sides of the chin, the breast, the sides and flanks broadly streaked with 

 walnut-brown, the streaks coalescing on the sides of the chin and mid-throat ; 

 the anterior part of the abdomen with dusky spots. 



4. First Nuptial Plumage acquired by wear which produces 

 slight changes. A few new feathers are usually acquired about 

 the chin in iNIarch, possibly the beginning of a more extensive 

 moult. My latest spring specimen is April 8th. 



5. Adult Winter Plumage acquired by a complete post- 

 nuptial moult. Practically indistinguishable from first winter 

 dress. 



6. Adult Nuptial Plumage acquired by wear as in the 

 young bird. 



Female. — The sexes are alike and the moults correspond al- 

 though females may average duller in colors. 



Pipilo erythrophthalmus (Linn.). Towhee 



1. Natal Down. Pale clove-brown. 



2. Juvenal Plumage acquired by a complete postnatal moult. 



Above, including sides of head, cinnamon-brown (often darker) somewhat ob- 

 scurely striped, broadly on the back, more narrowly on the crown, with deep
