Buttonquail ?
Hi,
In mid-May 2001 (I think) I encountered two buttonquails when driving up Robin's Nest (Hung Fa Leng), which is similar habitat to Kai Kung Leng. I didn't have the camera with me, but the buttonquail walked right past the car once I had stopped. I was confident they were Barred Buttonquail, but I guess my record either got lost or was rejected.
Anyway, Prof. CHENG's "Synopsis of the Avifauna of China" describes Barred Buttonquail as resident in South China. Birders don't go up Hongkong's hills very much in high summer, and buttonquail are hard to flush out as well.
I'm sure that sooner or later someone will get a satisfactory sighting or record shot of Barred Buttonquail as a HK breeding bird !
