YELLOW-BREASTED BIRDS. 125 



a ' Pdetera ! peetera ! p^etera ! ' then a whistling 

 ' Tui ! ' in the style of a Willow- Wren, but stronger ; 

 at another time it becomes a metallic ' Oit-a-l6ng ! 

 git-a-l6ng ! ' or an incisive ' Ping ! ping ! ' or oftener 

 still a chuckling ' Ghur-r-r-r ! ' Seen from below, 

 the heavy black band dividing the breast longi- 

 tudinally, set off by the bright-yellow under parts, 

 stamps the Great Tit at once.

 black ; white patch on the nape much larger" relatively 

 to the size of the bird ; back olive-gray ; under parts 

 grayish-white, but no black breast-band. 



MARSH-TIT— 4J inches ; head, nape, and chin black ; no 

 white nape - patch ; back olive - brown ; under parts 

 grayish-white, but no black breast-band. 



BLUE TIT — 4i inches ; blue head a^d wings ; sides of face 

 white, divided by a dark stripe passing through the eye ; 

 under parts yellow, with central blue streak, but not 

 comparable with the Great Tit-'s heavy black breast- 

 band.
