The Thrushes 
attention lias been paid to the recording* of the song of the 
acclimatized birds;—there is no fear of their extinction 
It has been impossible, however, to avoid noting an apparent 
change in the habits of thrush and blackbird. During the 1921 
season four thrushes ’ double nests were found, following the 
finding of the fantail’s double nest already referred to. All were 
found by school-children, who sent to me two of the nests and 
the measurements of the third. 
One nest, found in a macrocarpa pine, at Papakura, Auckland,, 
is composed of roots and dry grass: the foundation is coarse 
roots and grass with a mixture of clay and cow-droppings, the 
roots becoming finer as the walls rise, the cup being lined with 
the finest. The nest is not finished, the clay lining not having 
been put in. The measurements are:—Inside of cup, 31 in. 
across, 2\ in. deep; whole nest, outside, cup 5 in. across, 10 in. 
across the two nests, height at angle where both join, 71 in. 
Angle made by slope of the two cups 112°. 
The second nest, from Te Mapara, Auckland, is composed 
almost entirely of dry grass and bents; there are a few twigs, 
and a very little moss. The cups are lined with dark clay and 
droppings, smoothly covered with shredded decayed wood, pale 
yellow or straw-colour, in appearance like dried Westland moss; 
one cnp is darker in colour because less covered with the yellow 
wood. This is a beautifully finished nest. The measurements 
are:—Inside of cup, 31 in. across, 21 in. deep; whole nest, out¬ 
side, cup 6 1 in. across, 10 in. across the two nests, height 6 in.; 
angle made by slope of the two cups, 110°. 
The third nest, from Mangamahoe, near Wellington, has not 
been seen by me. The measurements given are:—Inside of cup,, 
3! in. across, 2f in. deep; whole nest, outside, cup 5 in. across, 
81 in. across the two nests, height 4 J in.; angle made by slope of 
the two cups, 115°. 
A fourth nest was reported from near Mangamahoe. The 
nest was built in a wineberry (makomako), and there were eggs 
in both cnps,—four in one and two in the other. On the nest 
being approached a bird flew off one part, whilst the eggs in
