valley lands and lower mountain slopes. It is much more num- 

 erous in the fall as a migrant, when sometimes scattered com- 

 panies pass over the Highland, taking short flights from perch 

 to perch on their way, or scatter about for a brief sta}^ On 

 September i6, 1903, such a company numbered by count nearly 

 a hundred birds. On other occasions fifteen to twenty birds 

 have been seen. Sharp-shinned Hawks, migrating at the same 

 time, sometimes chase the Flickers about the pasture lands. 



79. Antrostomus vociferus vociferus. Whip-poor- 



W11.1.. 



An uncommon and local summer resident, breeding at a 

 few points in the valley and in the Cherry Pond region. On 

 a few occasions one has been heard on the lower slopes of the 

 Highland. The first instance was on May 27, 1902, at three 

 o'clock in the morning. I had risen to make a full record of the 

 morning awakening of the birds by recording every voice heard 

 and the time at which each species first voiced itself. The 

 Whip-poor-will's song was then heard by me for the first time 

 in Jefferson, coming from the direction of the valle3^ The song 

 lasted fifteen minutes and then ceased. On two or three other 

 occasions one has been heard on the Highland. In June, 1907 

 and 1908, a pair probably bred in the Stag Hollow neighbor- 

 hood, as testimony was given me of repeated hearings of the 

 song in the evenings of June. Another pair has often been 

 located on the lower slopes of Mt, Starr King at an elevation of 

 about 1400 feet. 



80. Chordeiles virginianus virginianus. Nighthawk. 



An uncommon summer resident. The call has been heard 

 on a few occasions during the nesting season over the Highland, 

 but seldom has a bird followed up the narrowing valley to a 

 point so near the Presidential Range. Most of the instances of 

 hearing or seeing one have been at the Meadows or along the 

 turnpike where the forest has been burned. Here not infre- 

 quently a single bird, or a pair, has been heard, and the tum- 

 bling and booming witnessed. On July 2, 1904, sixteen birds
