MR. MILLER CHRISTY ON THE 
to which his attention had been drawn by the actions of a bird of 
that species. It was built in some Ivy on a wall. Shortly after it 
was discovered, three unmistakable Thrush’s eggs were laid in it, 
and these were duly sat upon by Thrush. Mr. Atkinson does not 
say whether the eggs were hatched or not. 
XXIII. Mr. Philip II. Hadlield, of Moraston House, near Eoss, 
Herefordshire, writes as follows in the ‘Field’ for May 1st, 1886 
(p. 570) : 
“ A Blackbird aud Soug Thrush recently took possession of the same nest, 
each laying therein (I believe in turns) three eggs. The eggs were, from 
accident, reduced to two Song Thrush’s and one Blackbird’s. The Blackbird 
then proceeded to sit on these, but, after a few days, deserted, owing to the 
noise of work carried on near the nest.” 
In a letter to me, Mr. Hadfield adds that the occurrence took place 
at Eoss. The nest, which he believes was a Blackbird’s, was 
built in some Ivy on some board palings. 
XXIV., XXV., and XXVI. IMr. F. E. Fitzgerald writes 
(‘Zoologist,’ 1887, p. 194) that in April, 1887, he found in a Holly 
bush on the Sewage Farm at Harrogate a typical Thrush’s nest 
containing four Blackbird’s eggs, and from which a Blackbird flew. 
A neighbour informed him that one of his sons had met with 
a similar instance near the same place the previous year. A friend 
had also informed him that he had met with a similar instance in 
Xidderdale. 
XXVII. Mr. J. Whitaker writes (‘Zoologist,’ 1887, p. 268) 
that in 1887 he found in a wood of 800 acres, where plenty of the 
usual lining material was obtainable, three Thrushes’ nests, all 
containing eggs, and all lined with grass like Blackbirds’ (instead 
of rotten wood). He had never, he says, met with similar Thrushes’ 
nests before. 
XXVIII. The following appeared in the ‘Field ’ of June 16th, 
1888: 
“ Interbreeding or Blackbird and Tiiritsh.— Ou May 22, 
I fouud on the end of a low branch of a fine old Yew tree a nest, from which 
a Blackbird rose, and giving its noisy notes of alarm as it flew away ; on 
looking into the nest I was surprised to find it contained two eggs, to all 
appearances Thrush’s, as they in no way differ from a typical Thrush’s egg. 
The nest is entirely composed of coarse and line grasses, roots, small twigs, 
and moss, with only an attempt of a mud lining on one side, and which is 
almost hidden by the lining made up of the other materials of the nesl.
