Dendroica caerulescens. Maine (Lake Umbagog). 1880. June 10. Set B-3. Incubated about eight days--arbor-vitae shrub among yew--height twelve inches; female slid from the nest when I was within about twelve feet. She re- turned almost immediately and showed great anxiety, chirp- chirping sharply, jetting her tail and dropping her wings like a Redstart, and flitting about within two feet of my head.

Upright fork of Yew; height fifteen in- ches; rather conspicuously placed and visible ten yards off; female absent; male singing twenty yards away; edge of dense bed of Yew, west side of Great Island. The nest contained two eggs which were perfectly fresh. I took them, substituting two eggs of the Chipping Spar- row. Returning June 13, I found that the female had laid only one more egg. She was sitting and permitted me to almost touch her. // Wpm 1881. May 14. Arrived to-day. Dendroica caerulescens. 1899. Oxford County, Maine. Sept.28 female, Bethel.
