Birds of Allegany Park 279 



most English words put to -bird song, " tink you terererere '" would 

 be better. Songs with but one low note followed by a trill. " ting 

 tr r r r." are common ; and other variations, sometimes rather puz- 

 zling, are to be heard. 



The nest is placed on the ground under bushes or a few feet up 

 in a thick bush. A nest found July 6 on Quaker Run, was in a 

 silky dogwood, and another with four eggs, found July 13 near 

 Red House Creek, was also in a bush. It may be that in this region 

 nests are commonly placed in bushes, but in most localities ground 

 nests are more common. 



Field Sparrow. Spizella pusilla pusilla (Wils.) 



The Field Sparrow is smaller than the English Sparrow. It may 

 be known by the unstriped, grayish white breast, pale reddish brown 

 upper parts with the head no redder than the back, and by its pink- 

 ish bill and feet. Young birds are striped on the breast. 



The Field Sparrow is one of the common thicket birds of the 

 Park, being found in young second growth where forests have 

 been recently cut, or in thickets that have sprung up on old pasture 

 hillsides. It is entirely characteristic of such places and not likely 

 to be found elsewhere. 



The song of this bird is one of the sweetest and purest in quality, 

 though simple in form. It consists of short, quick whistles that 

 grow rapidly faster, finally ending in a trill. Changes in the pitch 

 are usually gradual, the song slowly grading up or down to its 

 termination. The introductory notes are often slurred, more com- 

 monly downward, but frequently upward. 



■ The nest is placed in a thick bush two to four feet from the 

 ground. Rarely it is on the ground itself, but when this is the 

 case, under a bush. It is much like the Chipping Sparrow's nest, 

 lined with hair or sometimes grasses, but instead of blue, the eggs 

 are white and spotted with reddish brown. 



Chestnut-sided Warbler. Dendroica pensylvanica (Linn.) 



The Chestnut-sided Warbler, smaller than the English Sparrow, 

 is beautifully and strikingly marked. The top of the head is bright 

 yellow, and the remainder of the upper parts olive-brown, striped 

 with black, with broad yellowish white bars in the wings and white 

 patches on the outer tail feathers. The under parts are white, the 

 conspicuous white cheek patch marked off by black lines and each 

 side marked with a stripe of brightest chestnut. The male and fe- 

 male are similar but the male much more distinctly marked. 



This little bird is quite common in thickets in the Park. Wher- 

 ever original forest has been cut over and has grown up to sprouts 

 or seedlings five to ten feet in height, this warbler is common. It is 

 also found in the more open oak and chestnut forests, where there 

 is an undergrowth of such shrubs as azalea, blueberrv, silkv dog- 

 wood or Xew Jersey tea. It is entirely absent in the more dense 

 maple and beech woods. 



The song of this warbler is loud and clear, of fair musical qual-
