LEAST FLYCATCHER 81 



29. LEAST FLYCATCHER 



Empidonax minimus 



Every year of observation the Least Fly- 

 catcher, or Chebec, has been present in the 

 Garden. There have been nineteen occur- 

 rences of the species in the nine years. In 

 1906 there was but one visitant. In 1907 

 there were three records. The earliest ap- 

 pearance of the species was on April 29, 

 1908, one bird. The usual time of arrival is 

 between May 12 and 15. A second wave 

 of migration has brought others each sea- 

 son between May 17 and 20. 



In several instances the stay of a visitant 

 has covered nearly or quite a week. In 

 1902 a bird was present from May 17 to 

 23, seven days. In 1907 one was present 

 from May 19 to 24, six days. In 1908 two 

 birds were singing high up in the tops of 

 the tall trees on May 24. None in any 

 season has remained later than the last- 

 mentioned date. The species is usually in 

 song.
