126. [567] J imco hy emails (lAnn.). Slate-colored Junco.* 



Abundant winter resident. October 6 to May 1. 



Snatclies of song are often lieard in March and April and it has been 

 heard singing in the fall; November 9 and 23, 1902. On November 23, 

 1902, a bright, sunshiny day, one of three Juncos was observed carrying 

 dry blades of grass in its beak. It always gave them up in favor of new 

 ones every little while and did not put many of them in the same place. 

 On this same day a Junco was also heard singing a quite loud and pleas- 

 ing song. This occurrence should probalily ))e classed with those 

 phenomena which were discussed luidor the heading, "A Revival of Sex- 

 ual Instinct" in "The Auk" a year or more ago. A similar thing has 

 been noticed in the case of the English Sparrow. One was seen nest- 

 building November 6, 1902. 



Where there are weeds there are Juncos. But briary fence rows, and 

 thicketed gullies are centers of density in the Junco population.
