16 Wriacut, Orange-crowned Warbler in Massachusetts. an 
late autumn day in which the temperature had risen to 57°, with 
the air calm. One of the first birds observed was an Orange- 
crown in the thick shrubbery, as we ascended a flight of steps from 
the shore of the Cambridge cove of the pond to the park land above, 
occupied in part by large hemlocks and white pines, with fringes 
of shrubs. Its companions were Chickadees. On one of the 
hemlocks was a White-winged Crossbill in the plumage of the 
female, the only one seen in the fall and winter of 1915. Before 
leaving the grove we had seen the warbler several times by return- 
ing to its chosen haunt. Just before sunset another interesting 
bird appeared in the form of a Great Blue Heron in the sky, flying 
over the pond southward. I searched for the warbler the following 
morning, but could not find it. 
On December 7, I once more found an Orange-crown near 
Jamaica Pond in a somewhat extensive growth of young hemlocks 
near the memorial to Francis Parkman. It was in association 
with a late migrating Ruby-crowned Kinglet, two Golden-crowned 
Kinglets, and Chickadees. Mr. C. E. Clark of Medford had joined 
me, and we viewed the warbler together. It frequented the ground 
under the hemlocks much more than the branches of the trees. 
When undisturbed, it was generally feeding on the ground, and 
it sought the branches only when our approach became too close. 
Mr. H. L. Barrett recorded this bird on December 5, and Mrs. 
Lidian E. Bridge on December 8. The location of this Orange- 
crown was nearly identical with that of the bird of November 20, 
except that the hemlock growth stands somewhat farther back from 
the shore of the pond across the park drive. But that it was the 
same individual may be questioned, since I had looked for the 
warbler of November 20 on four successive walks through the park 
in the intervening time, namely, on November 23, 27, 29, and 
December 2, and had not been able to find it. On December 9, 
however, I again saw this later Orange-crown in the same location. 
On December 20 once more one was seen in the hemlocks. I had 
supposed that the last record for the season had already been 
obtained, for I had been through the park on December 13, 15, 
and 18, and Mr. F. H. Allen, as wei as others, had looked carefully 
for the bird of December 5 to 9 on the 11th and 12th, and no one 
of us had been able to find it. It may not be unreasonable to infer,
