ranks of the ones already on the ground were greatly aug- 
mented. During the entire month forty-four new arrivals 
were noted, only seven more than were recorded in March, 
which had an exceptionally large number this year. 
The first three days of May were rather unfavorable to mi- 
eration, but on the fourth there was a warm wave, which 
brought in six new migrants and added greatly to the species 
already here. This warm weather continuing to the twelfth re- 
sulted in a steady migration, which apparently reached its 
height on the evening of the 10th. A cold wave struck here 
on the 12th, but was replaced by a warm one on the evening 
of the 13th. With slight variations the balance of the month 
was fairly warm and favorable to migration. During the en- 
tire month fifty-six new arrivals were recorded, some of 
which, as the Least Flycatcher, Sharp-shinned Hawk, Catbird, 
and Baltimore Oriole should have been noted during the lat- 
ter half of April. There was a general migratory movement 
throughout the month, but the heaviest waves occurred on the 
4th, 8th, 11th, 14th, 15th, 16th, 17th and 21st, and the last 
new arrival was noted on June 2. Although about the usual 
number of migrants were recorded during May there was a 
remarkable scarcity of individuals among a great many of 
ihe species. This was especially noticeable in the Magnolia, 
Chestnut-sided, Palm, Black-throated Blue, Tennessee, and 
Wilson warblers, as well as the Grey-cheeked Thrush, Dick- 
cissel, and Least Flycatcher. On the other hand the Blue- 
headed Vireo, Bay-breasted Warbler, Golden-winged Warb- 
ler, and Grasshopper Sparrow were unusually numerous. But 
very few of the warblers prolonged their stay beyond the 
usual period, and the majority were here only a short time. 
In the following list of 141 migrants the various species 
are arranged in the order of their arrival, the dates given 
being the earliest record for the year. Species marked with 
an -*- occur in limited numbers as winter residents, ren- 
dering it very difficult to determine the exact date of the first 
migrating individuals of these species. In view of this the
