It is little heard in August. The last birds seen are usuall}' 

 recorded from September i8 to 23. On was seen on October 3 

 in 1905. 



91. Otocoris alpestris alpestris. Horned Lark. 



A rare migrant. On October 7, 1904, a flock of about fifty 

 birds was seen feeding in a ploughed field on the lower slopes 

 of Boy Mountain near the river. I was able to make several 

 near approaches to them, while they walked about or took short 

 flights to other parts of the field. They were all, so far as I 

 was able to determine, alpestris, plainly shovving yellow fore- 

 heads, eye-patches, and throats. This is the only occurrence 

 of which I have record. 



92. Otocoris alpestris praticola. Prairie Horned 



Lark. 



A locally not uncommon summer resident in recent years. 

 M}' first record was of two birds seen in Lancaster by the road- 

 side near the Connecticut River on August 7, 1S99. If the spe-

 notice until 1903, in which season and since then it has been 

 unfailingly in evidence. On July 13, 1905, fortj'-two adult and 

 immature birds were seen at the Meadows in three separate 

 flocks. At half-a-dozen localities in Jefferson the species has 

 nested in recent years. At the Meadows in June immature 

 birds have been seen with adult birds, and the song-flight has 

 been many times witnessed. 



In 1905 in a cornfield on the Highland a nest was built and 

 four young were reared. The nest was placed on the ground 

 after the planting of the field and was discovered on June 20, 

 when the corn was about four inches high and men were at 

 work running a cultivator. They saw the nest just in time to 

 prevent the horse from stepping upon it. I was informed, and 

 the next day I found in the nest birdlings covered with buffy 

 down. The nest composed of grasses w^as sunken in the ground
