86 BIRDS OF YARMOUTH AND VICINITY. ALLEN. 



533. Spimis pinus pinus (Wils.). Pine Siskin. — Irregular 



here. Common in 1901 and 1902; also in 1906, 

 1907, 1908. I have seen none since. On June 16, 

 1907, a male was observed in full song. The song 

 was typically finch-like, being a confused ramble, 

 and uttered while on the wing, the bird spreading 

 wings and tail and displaying all the yellow to the 

 utmost. Song again heard during June, 1908.

Snowflake. — Winter visitor. Very irregular in its
