Helminthophila celata. copy (r) Lake Umbagog, Maine 1895. Aug. 30. On my return as I reached the road I saw a small bird fly into a thicket of viburnum opulus. I made a low screeping when the bird at once showed itself, at first peeping out shy- ly from the foliage but finally hopping out on a nearly leaf- less branch where it permitted me to look at it for a minute or more through my glass from a distance of only six or eight paces. It was an Orange-crowned Warbler in full autumn plum- age, apparently a female for it had but little yellow on the under parts and that confined to the breast. There was anoth- er small Warbler in the same bush which I am practically cer- tain was also H. celata but which I cannot claim to have iden- tified with absolute certainty. Both birds behaved precisely alike hopping and flitting from twig to twig in the most ac- tive manner. Both flirted their wings nervously like Kinglets and wagged their tails slightly but unmistakably much in the manner of the Nashville Warbler. The one which I did not fully identify would not show itself fairly but I saw enough of it to feel really sure that it was the same as the other. Both birds were wholly silent. 16
