bough of an evergreen (usually the hemlock) from ten to 
twenty feet above the ground. Four or five eggs (in one case 
reported by Mr. Maynard, six) are laid in Northern New 
Hampshire and Maine in the second week of June. These 
eggs average ‘68°50 of an inch, and are bluish-green, with 
markings of brown and lilac, generally gathered in a ring 
about the crown. 
(c). The Bay-breasted Warblers are-among the many species 
who appear in Massachusetts as migrants only, and who pass 
the summer in a colder climate.2® They are, as a rule, very 
rare throughout the State in spring, and in autumn are never 
seen here. Mr. Allen, however, in speaking of this species, | 
says that ‘‘in the Connecticut valley it is generally more or 
less common and sometimes very abundant.” 
The Bay-breasted Warblers arrive here, after leaving their 
winter-homes in the South, in the third or fourth week of May, 
and frequent the woods and trees in open lands. I bave gen- 
erally seen them among budding maples, which like willows 
possess great attractions for the migrant warblers, but I have 
also seen them among pines. They are extremely active, and 
busily seek for their food among the branches, occasionally 
fluttering before the clusters of foliage, but they are not very 
shy, and asually permit a near approach. 
They are rare among the White Mountains, but Mr. Maynard 
speaks of them as being the *‘ most abundant of the Sylvicolidee 
at Umbagog,” and adds that ‘‘these birds are found in all the 
wooded sections of this region where they frequent the tops of 
tall trees.” He thinks that they are “confined during the 
breeding season to the region just north of the White Moun- 
tains range,” and makes the following interesting remarks on 
their travels. ‘* This species,” says he, ‘‘ together with Geo- 
thlypis philadelphia and Helminthophaga peregrina, seems to 
pursue a very eccentric course during the migrations. Avoid- 
ing the eastern and middle States, the majority pass along the 
29T have since learned that specimens have been taken here in both June and 
July.
