Index of Subjects Thanks to Paul for sending around the useful account of Horned Lark subspecies by Ron Pittiway. Essentially, the thing to look for is variation in the amount of yellow on the face: Yellow is extensive and strongest on face and throat our most common visitor, alpestris; The yellow is washed-out and largely restricted to the upper throat in our formerly breeding form praticola (only one confirmed record - in the Valley - in the recent Atlas); The throat and face are white with sometimes a hint of lemon yellow on the upper throat of hoyti. There are also differences in streaking on the upper tail coverts and back tones, which would help in distinguishing the latter two subspecies, There are specimens of all three in the NS Mus. Nat. Hist., but it would be good to have photos of the subspecies other than alpestris.
