Parus Hudsonicus, Lath. ■ 



A small party of this northern species visited Racine during the unusually cold 

 Januajy of 1852. 



AMPELID^E, (2 species.) 



BoMBTCiLLA Garrula, VieiU. Black-throated Waxwing. 



Arrives in large parties from the first to the last of November, and leaves by the 

 15th April. The first arrivals are all young birds, destitute of the yellow markings 

 on the wing, and with less of the wax-like appendages. These young birds gene- 

 rally proceed further south to winter, while the old birds, in perfect plumage, arrive 

 later, and seldom, if ever, go further. I never have seen an individual entirely des- 

 titute of wax ornaments. The only perceptible diiference between the sexes is in 

 size, the females being slightly the larger. lu fifty specimens accurately measured 

 the average was : 



Females, - - - 8 5-12—W4 



Males, - - - 82-12—1334 



They are unsuspicious, permitting a near approach. Their fare consists of a vari- 

 ety of berries, but those of the moantain ash, {Pyus Americana,) appear to be pre- 

 ferred to all others. They are frequently seen to eat snow as a substitute for drink. 



*Bombycilla Americana, Swain. Cedar Bird. 

 Common, does not remain during winter. 



ALAUDINtE, (2 species.) 



*Otocoris Alpestkis, Linn. Horned Lark. 



Abundant on the prairies. A few remain during the entire winter.
