on June 2?, 1903, at Errol, he flushed a female from her nest, 

 containing two newly hatched young and one ^z^. He says 

 that at least two pairs were breeding here. The only other 

 summer record is that of a single bird seen by Mr. C. F. Good- 

 hue at Boscawen on June 25, igoi. As far as at present known, 

 therefore, the Prairie Horned I^ark summers in New Hampshire 

 in small numbers on the fallow and pasture lands to the w-est 

 and north of the White Mountain region. A migrant bird was 

 also recently sent me from Randolph, where it was taken on 

 March 6, 1902, by Mr. V. D. L,owe. 



Dates : (Last of February?) March 6 to August (September and Octo- 

 ber?).

A permanent resident, of general distribution throughout the 

 Transition and sub-Canadian areas of the state, apparently not 

 breeding above 3,000 feet in the White Mountains. After 

 the breeding season, small flocks, apparently composed of 

 the individuals of a single family, are often noted wander- 

 ing through the woods. In the White Mountains during 

 August and September, these flocks reach the valley bottoms, 

 and may then unite to form companies of from six to fre- 

 quently 20 or 30 birds. They appear to be migrating in 

 a leisurely way, and at Intervale I have frequently seen them 

 moving down the Saco valley, in earl}^ forenoon or late 

 afternoon. At such times, I have seen them, one by one, fly 

 from one large tree to another farther down the river valley, 

 where the first arrivals wait for the rest to come up, and then 

 move on again as before ; or the entire flock may keep well to- 

 gether and go trooping down across the meadows from tree to 

 tree. It is possible that these migrations are not very exten- 

 sive, but in the White Mountain valleys thej- are certainly well 

 marked. In. the northern woods, these Ja3's appear to be unus- 

 ually quiet, and one may pass an entire day where they are not 

 uncommon, without hearing their loud screams, though by im- 

 itating their alarm cry, it is possible to get an immediate reply, 

 and bring the inquisitive birds to the trees above one's head. 

 The wandering flocks in summer occasionally reach considera-
