little, and most of the birds deserted their thick winter coverts, ap- 
pearing in town and on the prairie, while all the songsters burst forth 
in full spring melody. Blackbirds, both Red-winged and Cowbirds, 
increased decidedly; grass started everywhere, and one wild flower 
was found. 
Directly east of Saint Louis the wave can be traced to Odin, Il. (lat. 
38° 39’), where the atmosphere was warm from January 27 to February 
4. The snow had all gone, and Geese appeared January 31, followed by 
Ducks February 2. West of Saint Louis the migration of Bluebirds 
was observed at Mount Carmel, Mo, (lat. 38° 45’), and of Robins and 
Geese at Glasgow, Mo. (lat. 39° 14’). 
Above are the limits of this wave, which, although of great extent to 
the south, east, and west of Saint Louis, proceeded no farther north. 
A study of the Signal Service report shows the reason for this. Al- 
though the warm wave was felt for several hundred miles north of Saint 
Louis, yet its power was not sufficient to produce any marked thaw or 
breaking up of the streams. Indeed, even in the latitude of Saint 
Louis, no marked effect was observed, except in the lowlands. Stations 
in the vicinity of Saint Louis, and only 30 or 40 miles farther north, did 
not feel its influence. And the same is true in the West. In Kansas 
there was no movement of birds. At Manhattan (lat. 39° 12’), though 
in the same latitude, there was no migration, and the Signal Service 
reports show that the nights were cold, and winter reigned until a month 
later. An apparently accidental movement was reported from Unadilla, 
Nebr. (lat. 40° 53’, F. C. Kenyon), where Geese arrived January 31, and 
Ducks February 2; butit is possible that these birds were driven back 
from the north, as both Ducks and Geese had been reported January 11 
from Vermillion, Dak. (lat. 42° 56’)—a locality where they had never 
before been seen in winter. A single record of Robins and Bluebirds 
came from Carlinville, Ill. (lat. 39° 18’), February 2, with the statement 
that no others were seen for two weeks (Chas. W. Robertson). 
Second wave.—The second wave began at Saint Louis during the 
night of February 18, and was cut short on the 19th at 11.30 a. m. by 
a fierce snow-storm from the northwest. On the 18th, in the afternoon, 
the temperature rose rapidly with a good breeze from the southeast 
which moderated in the evening, but the temperature remained at 50° 
all night. The sky was clear in the evening, but cloudy in the morning. 
This wave brought more Robins, Bluebirds, and Purple Finches; many 
Mallards, Sprigtails, Green-winged Teal, and Canada Geese; it took 
off about half the Tree Sparrows (Spizella monticola), and brought the 
first migrants of the Goldfinch (Spinus tristis), White-crowned and 
White-throated Sparrows (Zonotrichia leucophrys and albicollis), Field 
Sparrows (Spizella pusilla), Song Sparrows (Melospiza fasciata), Swamp 
Sparrows (Melospiza. palustris), Fox Sparrows (Passerella iliaca), and 
Chewinks (Pipilo erythrophthalmus). It appears to have been a local 
wave. No other stations reported any movement whatever on those
