OUR BIRDS THROUGHOUT THE YEAR 371 
pecker, Downy Woodpecker, Snowbird, Tree Sparrow, and 
Chickadee. Three species seen last winter, but not this, were: 
Bronzed Grackle, Meadowlark, and Snowflake. 
The March records for 1915 totalled 19, which was 11 fewer 
than those of 1914. The eleven species not found March, rgr5 
were: White-breasted Nuthatch, Goldfinch, Screech Owl, Chick- 
adee, Hairy Woodpecker, Cardinal, Snowflake, Sparrow Hawk, 
Purple Finch, Sapsucker, Phoebe. 
The latest record in February for the White-breasted Nuthatch 
was the 27th; no record occurred in April; the bird reappeared 
on the rst of May, and disappeared until June 20th. Barring the 
one May record, we have the unprecedentedly long absence of 
111 days. The spring migration of this species has always been 
exceedingly interesting to me, but I am at a loss to know what 
can be the determining cause of its withdrawal as_ spring 
approaches. 
Another species that is irregularly seen in winter and early 
spring is the Goldfinch. This year the only record in February 
was on the 23d. After this date the species failed. to appear until 
April 13th—an absence of 48 days. Who can explain this 
irregularity? 
The species recorded in March, 1915 were: Crow, Blue Jay, 
Red-headed Woodpecker, Downy Woodpecker, Song Sparrow, 
Brown Creeper, Tree Sparrow, Snowbird, Meadowlark, Bluebird, 
Robin, Killdeer, Herring Gull, Canada Goose, Red-winged Black- 
bird, Bronzed Grackle, Flicker, Kingfisher, Cowbird. 
The most abundant species in March were: Crow, Blue 
Jay, Snowbird, Meadowlark, Bluebird, Robin, Red-winged Black- 
bird, and Bronzed Grackle. Less abundant species were: Downy 
Woodpecker, with 5 records; Herring Gull, with 6; Tree Sparrow, 
with 9; Red-headed Woodpecker and Killdeer with 13. The 
least abundant species were: Brown Creeper, Canada Goose, 
Flicker, Kingfisher, and Cowbird, each with one record. 
Dates of migration in March were: Meadowlark on the 
3d; Canada Goose, on the gth; Red-winged Blackbird and 
Bronzed Grackle, on the 12th; Flicker, on the 19th; Kingfisher, 
on the 30th; Cowbird, on the 31st. Against these seven migrants 
there were 18, in March, 1914. 
The followiug disjointed observations, made in March, 1915 
may be of interest: March 3.—Mating song of Blue Jay was
