Behle 1934 205 Plush, Warner Valley, Oregon to Modoc Region Calif. Aug. 25 south to Fort Bidwell over the magnificent roads in the country. Just after crossing the California - Oregon line I saw some larks in the sagebrush rocky country and spent an hour to secure but one. This is the first time this trip that I have met up with them in brush. Their occurrence here is probably because they leave the flats and come up to the hill-sides and rocky areas this time of year where insects are a little more abundant. Findale claims they do this. Drove on a short distance to cow head lake which is now dry. One place there was a spring or marsh and Horned Larks were numerous here evidently attracted by the insects. This same condition was encountered at Byron Hot Springs. I shot several here, at each shot the flock would fly about coming back to the marsh landing on the edge. These birds I think resemble those of the Warner Valley to the north. There is certainly a difference between adult males in fresh plumage and birds of the year or 1st fall plumage. The adult boys have so much more yellow on throat and chest.
