her to be a young bird; she then darted directly to 

 the earth and ran, but when deceived I sought her on 

 the ground she had very expertly disappeared, and I

 white, inclining to flesh-colour, variegated, more par- 

 ticularly at the great end, with pale purplish points of 

 various sizes, interspersed with other large spots of 

 brown and blackish. The nest was formed of circularly 

 entwined fine stripes of the inner bark of the juniper, 

 and the tough white fibrous bark of some other plant, 

 bedded with soft feathers of the E-obin, and lined with 

 a few horse-hairs and some slender tops of bentgrass,

My friend describes the notes of this species as 

 follows: — ^This simple, rather drawling, and somewhat 

 plaintive song, uttered at short intervals, resembles the 

 syllables '^te de territica,' sometimes 'tederisca,' pro- 

 nounced pretty loud and slow, and the tones proceeding 

 from high to low.' These notes 1 am well acquainted 

 with, but none can describe the songs of our difl!erent 

 species like JSTuttall." 



My figure is taken from Audubon's large folio work, 

 the drawing being kindly executed for me by Mr. 

 Sinclair, of Glasgow, to whom I shall also on another 

 occasion have to express my obligations. 



Figured also by Wilson and Nuttall.
