We reported 5 nests of the Elliot’s Laughingthrush (Garrulax elliotii) being parasitized by the Large Hawk Cuckoo (Hierococcyx sparverioides) at Gansu Lianhuashan Nature Reserve in the breeding season from May to August in 2011 and 2012. The eggs of Large Hawk Cuckoo were oval in shape and slightly blue in color with no spot. According to the measurements from two eggs, their size were 29.76 mm × 20.40 mm and 28.40 mm × 21.68 mm, with a fresh weight of 6.9 g and 7.2 g, respectively. One nestling of the Large Hawk Cuckoo fledged on Day 20 after hatched.
