loud in the tree tops or low in the hedges, on the first day of its 
arrival. 
The Myrtle Warbler usually arrives regularly in the third 
week of April, the greatest difference in four years being only 
four days—April 16 to 20. Later dates were May 2, 1910, and 
April 26, 1912. From these records it may be seen that the whole 
period of migration covers 16 days. 
Although the dates of the Barn Swallow are more scattered 
than those of the Myrtle Warbler, still the period of migration 
is the same—16 days in April. This year the species arrived on 
the 22nd, which is one of the late dates. The record last year 
was the 11th, the earliest I have made. 
Some species that were winter or spring visitants and departed 
for the north in April were: Brown Creeper, Golden-crowned 
Kinglet, Purple Finch and Tree Sparrow. The Tree Sparrow’s 
date of departure in 1914 was the 23rd, which is identical with 
1912. In 1913, this species left us on the 6th, which is certainly 
quite irregular when compared with the other two dates. The 
Purple Finch, in three years, departed on the 14th in 1909, on 
the 9th in 1911, on the 18th in 1914. In four springs, the Golden- 
crowned Kinglet retired north on the 27th in 1910 and 1912, 
on the roth in 1913, on the 23rd in 1914. The Brown Creeper’s 
latest dates for three years were: the 30th in 1912, the 22nd in 
1913, the 26th in 1914. 
A number of unusually early records for certain species was 
made in April of this year. Among these are the following: Balti- 
more Oriole and Spotted Sandpiper, on the 25th; Catbird, Chimney 
Swift, and Warbling Vireo, on the 26th. Yellow Warbler, on the 
27th; Orchard Oriole and Kingbird, on the 28th. Most of my 
other earliest records of these species occurred in May. 
Most of the May migrants this year were remarkable for 
their regularity. A comparison of a few records in 1913 and 1914 
will readily indicate this fact. Dates of arrival in 1913 and 1914: 
Chestnut-sided Warbler, 5th and 4th; White -crowned Sparrow, 
7th and 6th; Blue-headed Vireo, 1oth and 11th; Least Flycatcher, 
12th and 14th; Scarlet Tanager, 13th and 11th; Wood Pewee, 
14th and 11th; Blackburian Warbler, 11th and 16th; Magnolia 
Warbler, 16th and 13th; Black-poll Warbler, identical.—Dates 
of departure in 1913 and 1914: Ruby-crowned Kinglet, 3d and 
5th; Myrtle Warbler, 15th and 17th; White-crowned Sparrow,
