The first published record of the presence of the Kingbird in Costa Rica 

 is that by Mr. Bangs, cited above. It would seem that there are no speci- 

 mens of it in the U. S. Nat. Museum from Costa Rica, for Mr. Ridgway 

 makes no mention of its occurrence in that country. It is not a rare bird 

 in Costa Rica by any means, being found in the lowlands of both coasts 

 as well as in the high interior. I frequently saw the bird perched on the 

 telephone- and telegraph-wires along the railroad on the Old Line near 

 El Hogar, but never collected any specimens. Its habits in the winter 

 undergo no change, and it is the same pugnacious fighter there as on its 

 breeding grounds.

The Derby Flycatcher has a wide distribution in Costa Rica, covering 

 both the Caribbean and Pacific lowlands, with the exception of the Ter- 

 raba region, where it seems to be entirely wanting. It is occasionally 

 found in the central highlands, but in small numbers, and is most abundant 

 in the Caribbean lowlands below 1,500 feet. It is a common bird about 

 Guapiles and along the Sicsola River, in southeastern Costa Rica. In 

 habits, actions, note, and manner of building its nest this bird shows a
