lii,yli Hyiiii;- liahit of tlic birds. It is iilinost ini]>(»ssibl(' to obtain any

Two specimens shot on the llio Frio, from a largecomi)any of Swifts, 

 Jind others were collected on the Escondido, at " I. P." plantation,

 si)ider\s web or bright-colored flower, of which there are many in these 

 l)Iaces. When darting rapidly through the woods, it utters a sharp, 

 shYill "chweep" at short intervals, audit is not a little startling to

 one's head. Feet flesh-colored.
