Oven-bird. Seiurus aurocapillus (Linn.) 



Length 6.2. Upper surface brown; crown dull orange, edged with black, 

 lower parts white, black-spotted. 



The Oven-bird frequents dry open woods, and it seems restricted 

 to this habitat. The favorite woodland must be well matured, as 

 for example, the forest on a dry knoll where lumbering was done 

 in an early day so that the large deciduous trees were left tolerably 

 intact, and second growth conifers are now mixed in small propor- 

 tion. An undue amount of ground cover will cause the Oven-bird 

 to look elsewhere, for it prefers places where it can walk about un- 

 hindered in hunting its food among the leaves and litter. It derives 

 its name from the shape of its nest, which is made in a little niche 

 on some wooded hillside and arched over by tw T igs and leaves, with 

 an entrance at the side ; thus reminding one of an old-fashioned 

 outdoor oven. The eggs are white with red and brown spots. 



Black-throated Green Warbler. Dendroica wrens (Gmel.) 



Length 5. Back olive-green ; cheeks greenish yellow; throat and breast 

 black; under parts white, streaked with black; vest 3-ellow; wing-bars 

 and spots on tail white. 



This warbler is associated with the coniferous species of the 

 mixed woods, preferably in its more open aspects in the minor growth 

 along the borders of a bog or the virgin forest. Mearns reports that 

 " it is found everywhere, in all kinds of woods ; but is especially 

 numerous in hemlocks growing among deciduous trees." Hoffmann 

 describes it as " the chief inhabitant of the white pines, where one 

 hears continually its wheezy notes. It is also a common resident of 

 the red cedar or savin groves of southern New r England, and of the 

 spruces of northern New r England and New York/' 



* Blackburnian Warbler. Dendroica fusca (Miill.) 



Length 5.3. Back black streaked with gray; crown and line under eye 

 black; throat, breast and line over eye bright orange; wide white wing- 

 bar ; lower parts yellow, streaked on the sides. 



This gaudy warbler was not seen by me, but it has been frequently 

 reported in neighboring counties and will no doubt be found some 

 day at Cranberry Lake. Eaton speaks of it in the Adirondacks as 

 " one of the characteristic woodland warblers, being practically as 

 abundant in the depths of the forest as about the edges of clearings 

 or along the streams." It nests and hunts and sings its thin, sharp 

 warbling, high up in the evergreens. 



Black-poll Warbler. Dendroica striata (Forst.) 



Length 5.5. Back streaked gray; crown black; checks and wing-bar 

 white ; lower surface white, streaked on the sides. 



The Black-poll seems to prefer the open bog forest where there is 

 an association of young and medium-sized conifers in sphagnum 

 ground, and of low bog shrubs in cleared spots and illuminated 

 openings. This preference for small growth leads the Black-poll 

 higher on the mountainsides than other warblers associated with 

 coniferous forest.
