Nidification. The Thick-billed Shrike breeds in some numbers in Japan, where Alan Owston's collectors found their nests both on Mt. Fuji and also in Shensu. The nests are described as the usual deep cups made of very miscellaneous articles but chiefly of grass and small twigs and they appear to be most often placed in low cherry and other fruit-trees in gardens and orchards. The eggs number four to six and are like those of Lanius collurio, the pink type being more numerous than the others. As a series they are bright, richly coloured eggs with bold markings. Fifty eggs average 22.2 x 16.7 mm.: maxima 24.1 x 17.2 and 22.0 x 17.8 mm. ; minima 21.2 x l6.7 and 22.4 x 15.3 mm.

They breed during May and June.

Habits. Those of the genus but this Shrike prefers well-wooded though open country and is not a frequenter of the deserts and more arid stony hills. It is often found round about villages and cultivation. Alan Owston recorded it as very rarely breeding in Japan except in certain years, when it was, on the contrary, very numerous during the Summer, especially frequenting orchards. It has a sweet and powerful song.
