162 THE ZOOLOGIST. 



Parus major and P. cceruleus. — Occasionally seen. 



Troglodytes parvulus. — About gardens, several times. 



Motacilla alba. — Saw a few. In the Botanical Garden was 

 the only adult female, so far as I could judge, that I saw in 

 Belgium. It had the crown sooty mixed with grey. 



*M. melanope. — To my great surprise, I saw a black-throated 

 Grey Wagtail sitting on a bare twig over a piece of water in the 

 Botanical Garden. A tidal creek, or branch of the Dyle, bounds 

 the garden on one side. 



Anthus trivialis. — Seemed fairly common about wayside 

 poplars. 



Oriolus galbula. — I heard the note in a wood near the Chateau 

 Kubens. One bird (and I think another also) was singing in the 

 thickest parts of the tall trees which stand round the Botanical 

 Garden. I moved it more than once, and at last got the glass on 

 a male as it flew out. It is far from a conspicuous bird when 

 seen against a background of fresh green, and moreover it is loth 

 to leave the thick foliage. Its sweet rich "lit-a-vool" or "lit-a- 

 vool-ee " was, I think, followed by some low chattering notes, 

 heard only on two occasions, when I was just under the place 

 where I thought the bird was sitting ; but I could never see it 

 when it was perched. 



Lanius collurio. — One male. 

 *Muscicapa grisola. — Several about the Botanical Garden. 



Hirundo rustica. — In fair numbers. 



Chelidon urbica. — A few only compared with some places. 



Passer domesticus. — Not conspicuously abundant. 



P. montanus. — Saw a good many. Some seen about pollard 

 trees, and several times dusting by the roadside. Apparently 

 rather a common bird in Belgium. 



Fringilla ccelebs. — About gardens and wayside trees. 



Emberiza citrinella. — Fairly common by the roadsides. Some 

 males were very bright, as at Dinant also. 



E. shoeniclus. — Several along the high banks of the tidal 

 Dyle ; also about reeds in the grass marshes, and along a canal. 



Sturnus vulgaris. — Common about grass marshes, &c. Some 

 were in flocks ; others inhabited St. Rombaut's great tower. Seen 

 in Antwerp. 



Pica rustica. — Several times seen by the wayside.
