An investigation has been conducted in Dongzhai Natural Reserve from April to July,2008.A nest of Crested Goshawk that contained a nestling and an egg was found.This has been the first record of this species in Henan province,which indicates that the distribution area of Crested Goshawk is extending to the east and to the north.The habitat type for Crested Goshawk in Henan province remains to be determined.
Ectoparasites and other invertebrates are known to play a role in bird behavior and in evolutionary adaptations such as preening and foraging strategies. We conducted an exploratory study by macro- and microscopically evaluating the nests of Hair-crested Drongos(Dicrurus hottentottus) at Dongzhai National Nature Reserve, Henan Province, China in 2011 to determine if there was a presence of invertebrates. We developed a modified funneling technique to collect invertebrate samples and reduce contamination from outside sources in a field setting. We found several species of ectoparasites(lice and ticks) and other invertebrates(springtails and rove beetles) within the nests. Our findings warrant further investigation as to whether or not the presence of invertebrates in the nests of Hair-crested Drongos plays a role in the adaptation of the unique nest dismantling behavior exhibited by this species.
