THE BIRDS OF COOKHAM AND THE NEIGHBOURHOOD. 149 
Otus. 
10. Otus vulgaris. The Long-eared Owl. 
This bird is very rare at Cookham, but has nevertheless been 
observed by Mr. J. Ford, at Dropmore, where there are some 
fir trees, which are a favourite resort of the Long-eared Owl. 
The species is common in some parts of Cambridgeshire, whence 
several specimens have been sent, both to Mr. Briggs and 
myself, and where the bird often came under his observation. 
Mr. J. Ford had a young bird sent him from Norfolk, which 
lived for a long time ia confinement, till it met with an untimely 
death at the claws of a cat. 
11. Otus brachyotus. The Short-eared Owl. 
Mr. Darby shot a specimen of this Owl near Cockmarsh a few 
years ago, which was preserved by Mr. J. Ford, of Cookham. 
Its occurrence so far south is rare. 
Sub-fam. STRIGINZ. 
Strix. 
12. Strix flammea. The Barn Owl. 
Our harmless but persecuted Barn Owl is often met with at 
Cookham, and occasionally visits Formosa, where it meets with 
an asylum. It is also a frequent visitor to White Place, and may 
be often heard in Cliefden Woods. Ihave also heard and seen 
it in the ivy which envelopes the tower of Cookham Church. 
Order FIsstRosTRE. 
Fam. HirunpDInip&. 
Hirundo. 
13. Hirundo rustica. The Chimney Swallow. 
The present species presents at different seasons of the year 
_ distinct changes of plumage on the breast, but I am at present 
not in a position to make any remarks about them, as I intend to 
_ make my researches the subject of a separate paper. I question 
_ very much, however, whether the old bird at the time of feeding 
the young on the wing (as represented in Mr. Gould’s plate in 
_ The Birds of Great Britain) is to be found with the reddish tinge 
ot 
on the breast, but as ty series of specimens is not yet as complete 
as I could wish, I must wait till next year to bring me some more,
