This season (1885) the cock Red-back has again been 

 observed near the old breeding place. 



34. Muscicapa grisola. Spotted Flycatcher. 



Regular summer visitant to the valley, and breeds. 



35. Muscicapa atricapilla. Pied Flycatcher. 



This migrant nests occasionally m the lower and more culti- 

 vated parts of the valley, but is by no means common. 



36. Hirundo rustica. Swallow. 



Found throughout the valley in summer. 1 possess an egg 

 taken in May 1884 from an old barri near ^looi House ; 

 elevation 2,000 feet! 



37. Chelidoa urbica. House Martin. 



Common in summer throughout the valley, and is found 

 breeding up to about 1,150 feet. 



38. Cotyle riparia. Sand Martin. 



There is an extensive colony of these birds about two miles 

 above Middleton, on the left bank of the river : beyond that 

 point I do not think they breed. 



39. Carduelis elegans. Goldfinch. 



Occurs not unfrequently during hard winters. 



40. Chrysomitris spinus. Siskin. 



Frequently seen in flocks during winter time (N. Wearmouth). 



41. Ligurinus chloris. Greenfinch. 



Fairly abundant about the wooded portions of the Tees valley, 

 and breeds regularly. 



42. Coccothraustes vulgaris. Hawfinch. 



Five or six years since a nest was found in a large thorn bush 

 in Park End Wood, on the Yorkshire side of the Tees, about two 

 miles north-west of Middleton. 



Four examples were also shot at iSIiddleton-in-Teesdale, m 

 the autumn of 1883. 



This year (1885), at the end of July, a male of this species 

 and a young one, apparently not long out of the nest, were 

 shot at Middleton, and brought for preservation to i\Ir. Wear- 

 mouth, of Newbiggin. 



43- Passer domesticus. House Sparrow. 



Seldom if ever ascends higher than the village of Newbiggin, 

 and even there it seems scarce, whilst numbers may be observed 

 at Middleton. 



44- Passer montanus. Tree Sparrow. 



Has occasionally been found breeding (N. W.), 



45- Fringilla coelebs. Chaffinch. 



By far the commonest resident woodland bird in the valley. 

 It c ompletely takes the place of the House Sparrow in the higher 



Oct. 1885.
