taining from 40 to 200 individuals, but the bird in my experience 

 was so rare that to see an individual was a treat, while a flock of 

 a dozen gathered by some condition of favorable food left a thrill 

 that is still remembered. At Formosa, Formosa, on August 23, 1920, 

 one passed down the Paraguay Kiver at dusk, evidently the first of 

 the spring migrants. Others passed Kilometer 80, west of Puerto 

 Pinasco, Paraguay, on September 6, 7, 8, 9, and 10, all bound south- 

 ward in evening, or once in early morning after a storm. The 

 migration ceased abruptly before there was opportunity to secure 

 specimens, and in work in the pampas I failed to find the birds, until 

 on February 7 at Lazcano, Uruguay, one passed the patio of the 

 hotel on the evening of February 7. At Rio Negro, Uruguay, from 

 February 13 to 17, the species was present in fair numbers and a 

 male was collected on February 16. Another was taken on the fol- 

 lowing day. In early evening iiacundas hawked about high in air, but 

 at dusk circled low over patches of weeds at the edge of town, at- 

 tracted by myriads of beetles that filled the air. On the 16th I 

 watched for them at the border of a small lagoon, and, after one or 

 two alarms from teru terus coming in silently to roost, was rewarded 

 by the sight of a goatsucker hawking low over the grass. In a few 

 minutes I had the bird in my hand where I could admire the beau- 

 tiful contrast of color in the plumage and the large, lustrous eyes. 



The wings in this species are short and the body heavy, so that 

 at times it presents an owllike appearance. The birds quarter back 

 and forth when feeding like nighthawks, and though strong fliers 

 are not as graceful on the wing as birds of that group. They are 

 strong in body and often difficult to kill. When thej^ alight they may 

 stand erect for a moment to look about and then sink to the crouch- 

 ing position ordinary to goatsuckers. The leg is long and fairly 

 strong, and in one taken the feet were very muddy, an indication 

 that the birds walk about more or less, as might be supposed from 

 the structure of their legs. As they flush from the ground they 

 may give a low rattling call and a wing-tipped bird opened its mouth 

 threateningly and hissed like a nighthawk in similar condition. 



Near Rivas, Buenos Aires, eight were noted while passing in a 

 train on March 11,
