monotonous, weak, and inconspicuous among-the many spring songs. 
It is among the first of the Warblers to reach the state in the spring, 
and may be looked for late in April or in early May. 
YELLOW WARBLER, Dendroica aestiva aestiva (Gmel.) 
This species is the commonest and most sociable of the Warb¬ 
lers. It reaches the state with the advanced guard of the warbler 
host, by the third week of April. It frequents alike orchards, gar¬ 
dens, and shrubbery of lawns, or the wild tangle of swampland. Its 
simple, pleasing strain is one of the familiar sounds of summer. 
This species is of much economic importance about the orchard and 
garden in controlling aphids, weevils, small caterpillars and other 
insect pests. It would be difficult to find a more useful species 
among our summer birds. Nests are frequently built in fruit or 
ornamental trees. 
MYRTLE WARBLER, Dendroica coronata (Linn.) 
This species is the commonest of the transient warblers; the 
earliest to arrive in spring and the last to depart in autumn. It is 
usually found in open country as well as woodland. Its acquaintance 
is easily made; the yellow patches on crown and rump are distin¬ 
guishing features. The call note (tchip) is characteristic. 
It received its common name because of its fondness for myrtle 
berries; besides these berries, it eats other berries, seeds and insects, 
most of which are gleaned from the ground. 
OVEN-BIRD, Seiurus azirocapillus (Linn.) 
The Oven-bird, also known as Golden-crowned Thrush, is a 
true warbler. Its favorite habitat is moist woodland, where it lives 
on the ground, walking about among the leaves in the soft twilight 
of the undergrowth, looking for such insects as are usually found in 
such places. Its nest is dome-shaped and is always built on the 
ground among the fallen leaves. Because of the resemblance of this 
dome-shaped nest to an old-fashioned Dutch oven, the bird is known 
as the Oven-bird. In the quiet and solitude of its retreat, its song 
bursts upon the ear with startling force. Mr. John Burroughs 
describes its crescendo chant thus: 
“Teacher, teacher , teacher, TEACHER, TEACHER 
MARYLAND YELLOWTHROAT, Geothlypis trichas tnchas (Linn.) 
This Warbler shuns the forest, preferring the more open 
situations, particularly the low, bushy growths of moist ground. It 
is of a restless, inquisitive disposition, possessed of marked indi¬ 
viduality. Its sharp metallic call note is uttered upon the slightest 
provocation, but only an occasional glimpse of the bird itself, as it 
slips through the tangled growth, will reward the intruder. The
