ber and once in February. Last winter this species was seen on 7 

 days in December and once in February. In the winter of 1911-12, 

 the Tree Sparrow appeared as follows: Dec. i, 25; Jan. 31; Feb. 

 15 to 18, 20, 23, 24, 27, 28; Mar. I. The Snowflake was recorded 

 on Jan. 16, 1911; Mar. 2, 3, 1912. 



The Downy Woodpecker is the only species that is neither 

 very rare or very common in winter. In December, it was seen on 

 4 days, with three intervals of 6 days and one of 7 days. In Jan- 

 uary, the species was found on 6 days, with two long intervals 

 of 8 days and several short intervals. In February, this woodpecker 

 was present only on 3 days, with the longest interval of 14 days. 

 In March, the only record was on the 8th. 



Two records worthy of comment were the Herring Gull on 

 Jan. 17 and the Bluebird on Feb. 19. This was the first time in 

 winter that the writer observed the Herring Gull in the vicinity 

 of small inland lakes. The Bluebird has been seen before in winter, 

 but not with such a long interval between the first and second 

 observations. This year the first record of the species was made 

 on Feb. 19 and the second on Mar. 11 — an absence of 19 days. 

 On Feb. 19 the temperature rose to 60°, but was followed by cold, 

 stormy days for about two weeks.
