The Fork-tailed Flycatcher is a common bird in many parts of 

 Costa Rica and has a very wide distribution, being found in almost 

 every part of the country up to 8,000 or 9,000 feet, wherever cleared 

 lands are to be found. The habits of this bird are too well known to 

 need further comment.

The Scissor-tailed Flycatcher is not so abundant in Costa Rica as the 

 preceding, being only a winter visitor there, although present in con- 

 siderable numbers at times. It is most abundant in Guanacaste, espe- 

 cially around the Gulf of Nicoya, and spreading from there up over 

 the Pacific slope of the northern half of the country, as far as the valley 

 of San Jose. It habits are similar tQ those of the preceding species 

 and are also well known to students of ornithology.
