land. Numbers also nest upon the low-lying Borth and Teifi 

 bogs, whilst those nesting in the hills fly to the Dovey to feed at 

 low tide. Upon the bogs they may be seen to mob Carrion Crows 

 with much spirit, mounting above them and stooping almost in 

 the style of a Hawk. Though most of the eggs are hatched by 

 May 20th, a young one which I caught could barely fly on 

 June 30th. 



Whimbrel, N. phceopus. The spring passage begins with 

 great regularity within a day of the 3rd of May, and lasts through 

 the greater part of that month ; while in 1894 I heard the note as 

 late as June 21st. Few or none are seen on their return passage 

 in August. 



Bar-tailed Godwit, Limosa laponnica. Used to be plentiful 

 in the Dovey, but its numbers, like those of all the migratory 

 waders, have fallen off. Still seen at times in good large flocks in 

 August and September. Mr. F. T. Fielden only saw two in 1894. 



Black-tailed Godwit, L. cegocephala. One only, an imma- 

 ture bird, in the possession of Mr. F. T. Fielden. 



Greenshank, Totanus canescens. Small parties of not more 

 than four are seen fairly frequently on the Dovey in August. Mr. 

 F. T. Fielden has seen a Greenshank at one of the lakes in the 

 hills in April or May. 



Wood Sandpiper, T. glareola. Capt. G. W. Cosens has 

 a specimen which he obtained at Glandovey. 



Redshank, T. calidris. A few in the Dovey and Barmouth 

 river, but more numerous about the muddy inlet at Mochras 

 Island, near Harlech. It may breed there, as I saw a flock of 

 twenty-five on July 2nd, 1893. 



Green Sandpiper, Helodromas ochropus. Mr. F. T. Fielden 

 has seen one at the same spot for several years upon the Dovey. 

 One shot at Clarach is preserved at Gogerddan. 



Buff, Machetes pugnax. Only two occurrences. One was 

 shot by Mr. Hooton near Borth ; the other preserved by Mr. 

 Hutchings. 



Common Sandpiper, Totanus hypoleucus. Breeds upon all 

 the hill- streams and beside the llyns. Arrives with great punctu- 

 ality, generally on April 22nd. On May 31st, 1893, sitting had 

 not begun, as the birds were still in pairs, the males trilling and 

 tripping about with both wings raised vertically, or with one 

 held up flag-wise. Young birds frequent the Ystwyth in August.
