Mylarchus crinitus. Lake Umbagog, Maine. Approach to a song. 1897. When I entered the forest of stubs this morning (near June 3. the entrance to Leonard's Pond where I went to watch the Whis- tler's nest ) I was surprised to find the place perfectly si- lent and apparently deserted. What had become of the host of Swallows, Grackles and Woodpeckers which are nesting there? Literally not a bird of any kind was in sight or hearing. Half an hour later (I was at the Whistler's ne_st at 4.30 A.M.) they began calling, singing and flying about. I was especially interested in a pair of Great Crested Flycatchers. The female was building somewhere behind me but I could not remove my eyes from the Duck's nest long enough to follow her flights. The male sitting on the top of a stub nearly over me kept calling whit-whit-whit-whit-whit in tones mellow and musical for this harsh-voiced species. I suspect that this may be the nearest approach to a song of which the Great Crested Flycatcher is capable.
