80 BIRDS OF COOKHAM AND THE NEIGHBOURHOOD. 
the proper names to the different species of British birds, a rule 
very often neglected even by experienced ornithologists. The 
present bird has nothing at all to do with the Wrens (Zroglodytes), 
any more than the Willow Warbler, usually miscalled the Willow 
Wren, has. 
The Reed Warblers, as observed at Cookham, always build in 
the reeds on the banks of the Thames, or in the willows over- 
hanging the water. On no occasion have either Mr. Briggs or my- 
self noticed them building their nests at any great distance from 
water. 
Fam. Musotcariwwz. 
Genus BUTALIS. 
56. Butalis grisola. Spotted Flycatcher. 
This familiar bird is known by every one who has a garden, 
for nearly every verandah or trellis-work round the house is 
certain at one time or another to have been occupied by a Fly- 
catcher’s nest. At Mr. Burrows’ house, at Cookham, I have seen 
two Flycatcher’s nests in close proximity, and have taken great 
delight in watching the little birds busily engaged in feeding their 
young, and so fearless were they, as not to heed in the least the 
presence of many spectators. It is believed that the same 
pair always occupy the nest, which has been tenanted for a great 
many years. 
At a recent meeting of the Zoological Society, Mr. A. D. 
Bartlett, the well-known Superintendent of the Society’s Gardens 
in the Regent’s Park, mentioned that under the nest of a pair of 
Flycatchers built in his house in the gardens, he used to notice 
little pills upon the ground, being, as he expresses it, ‘‘ the most 
beautiful blue pills he ever saw in his life.” On examination he 
found that these little pills were peilets thrown up by the Fly- 
catchers, while the metallic blue appearance which they presented 
was caused by the remains of the outside cases of the bodies of 
blue bottle flies on which the birds had been feeding. Imay 
mention that the Spotted Flycatcher was among the birds recently 
brought home by Mr. Jesse, from Abyssinia.
