 March 3, 1921. 



At Roseraont (5,000 feet), a number of groups wei-e observed by Taylor, 

 one flock of twenty-five to thirty, but for the most part groups of four to 

 six. One of these groups was i)erched near a clump of mistletoe in an oak, 

 and one taken "had obviously been feeding on the berries. Forty or more 

 were noted all together.'' On January 16, thirty to forty were seen along Bar- 

 rel Canyon, and January 17, they were common below the ranger station. On 

 February 4, near the mouth of Madera Canyon, two flocks were noted. Febru-

 I)anies of four to six seen feeding on low bushes and on the ground, usually 

 with juncos.
