The Kachin Hills Laugliing-Thrush was first described by 

 Col. Rippon from the Kachin Hills east of Bliamo, where I 

 found it fairly plentiful at about 6000 feet. It has a very 

 fine whistling call, which can be easily imitated, and to Avhich 

 the bird readily answers. I only managed to get one nest, 

 which Avas found by my Burman collector, the parent bird 

 also being secured. The nest was placed in a clump of small 

 mountain bamboos, and was of the usual Laughing-Thrush 

 type, being composed entirely of bamboo leaves, and lined 

 Avith fine grass. It contained two incubated eggs of a bright 

 glossy blue, matching in colour those of Garrulax pect oralis, 

 but they are rather long and pointed, measuring 1-26 x '48.

Sharpe's Laughing-Thrush is the handsomest bird of this 

 numerous family, which is so well represented in the 

 Kachin Hills. It is a great skulker, and only found in 

 dense undergrowth in valleys over 6000 feet. My first nest 

 was procured by my Burman collector, who also shot the 

 parent bird. As these eggs differed from those of any other 

 Laughing- Thrush I had ever seen or heard of, and were of 

 a totally different type, I thought he must have made some 

 mistake. On the 29th of April, 1908, I luckily found a nest 

 containing three eggs of the same description as those taken 

 by him, so 1 promptly concealed myself, and managed to 

 shoot both parent birds, who Averc very noisy and inquisitive.
