Sayornis contains a small group of Tyrannidce allied to Ochihceca, 

 but of rather larger size, and with a longer and stronger bill, which 

 has induced the American ornithologists to place them near 

 Myiarchus. Their water-loving habits, however, as well as their 

 structure accord better with those of the Tceniopterin.ee. 



Two species of Sayornis, sometimes referred to different genera, 

 are summer visitants to the United States; the others range 

 through Central America to Bolivia. 



The nests of this group are open and cup-shaped, and placed on 

 rocks ; eggs white.
