446 Roosevelt Wild Life Bulletin 



Catbird. Dumetella carolinensis (Linn.) 



Length g. Slate-gray, with black head and tail ; under tail-coverts 

 chestnut. 



The Catbird inhabits the Partial and Habitation Clearings and the 

 bordering scrub about the campus. In the parts of the Burn nearest 

 the Camp this species was much at home, especially in the season of 

 ripe fruits and berries. The Catbird is an example of those species 

 that extend their range under suitable inducements, for early ac- 

 counts show that it was then confined to the borders of the wilder- 

 ness, while now it is met with throughout the Adirondack plateau. 



Redstart. Setophaga ruticilla (Linn.) 



Length 5.4. Black; sides of breast, band in wings and on tail, rich 

 salmon-red {yellow in female) ; lower parts white. 



The Redstart has very little association with the virgin forest, but 

 frequently dwells along the border of the bog forest where such 

 vegetation meets a burn or clearing. It enjoys small swampy spots 

 thickly grown with maple or willow or birch, perhaps with water 

 under-foot, the whole open pretty well around but darkened within. 

 In such retreats the Redstart hunts for its insect fare, and in an 

 upright fork makes its nest of bark and hemp-like fibres and lays red- 

 specked eggs. 



Canada Warbler. Wilsonia canadensis (Linn.) 



Length 5.5. Ash-gray above, forehead and crown blackish ; below 

 yellow, a broad band of black spots crossing the breast; no white on 

 wings or tail. 



This lively warbler haunts boggy and burnt clearings and the scrub 

 along the verge of the deep forest where plentiful light penetrates 

 the tangle and water is accessible. Ralph Hoffmann speaks of it as 

 very inquisitive. "An intruder may frequently hear its alarm-note, 

 chick, or catch a g'limpse of the black ' necklace ' across its yellow 

 breast as it flies low in the bushes. Its song is a rather hurried out- 

 pouring of notes, introduced by the same chick which it uses as an 

 alarm-note." Its nest is half hidden in a stream bank overhung 

 with moss, or some similar fastness ; and the eggs are white with 

 reddish spots about the large end. 



Maryland Yellow-throat. Geothlypis trichas trichas (Linn.) 



Length 5.2. Above, olive-green ; forehead and checks black, bordered 

 on the nape with gray (no black mask on the female) ; below, bright 

 yellow becoming whitish toward the tail. 



The Yellow-throat inhabits bushy openings wherever there is 

 sufficient moisture to produce a grassy growth among the shrubbery. 

 It chooses swampy depressions in the Burn, or the weedy margins 

 of streams and shores of ponds and lakes. The Meadow is an espe- 

 cially favorite habitat here, for, while dry in the summer, it supports 

 tall grasses, iris and small berry bushes, a combination well liked by 

 this ground-creeping Warbler. Among the stout grass stems it can 

 clamber and search for food ; and after one of its fluttering, ecstatic
