Messrs. Sclater and Salvin on the 
breeds commonly at Duenas in the months of April and May, 
making a nest of roots, fibres and small twigs with a lining of 
dry grass and fine roots. The eggs, three in number, are more 
or less covered with spots and blotches of red-brown on a 
ground of pale bluish green, the spots being more concentrated 
at the obtuse end. They measure 1 inch lines in axis and 
10 \ lines in diameter. 
The song of Turdus grayii is very rich and of considerable 
compass, quite rivalling any of its congeners. It is a favourite 
cage-bird with the Spaniards, and enjoys the name of ‘ Sinzonte’ 
in common with all other thrushes.

It is only in the higher parts of the Cordillera that this species 
is found; it occurs on the northern spur of the Yolcan de Fuego, 
near a small village called Calderas, at an elevation of about 
7000 feet. At Las Gordinas, in the Altos of Guatemala, and 
about the lofty hills that surround the Lake of Atitlan, it is 
tolerably numerous. In short, wherever the evergreen oaks 
attain their maximum growth, T. rufitorques may be found.

Fissirostres, and Scansores. The Passeres we divide, according to Muller’s 
views, into Oscines and Tracheophonce, the latter group passing on towards 
the Fissirostres.
