184 CUCULID^ CHKYSOCOCCYX 



naturalist who has observed the nesting habits of this cuckoo. He 

 says: "In December, 1891, I watched one of these birds for 

 several hours, and finally saw her fly into a thornbush close to a 

 picnic party. On going to the bush I found a nest of Andropadus 

 importunus containing two eggs with the usual markings of grey 

 and brown, together with a single large white cuckoo's egg slightly 

 incubated, while the others were fresh, I have noticed that both 

 this and the former species [Giiculus solitarius) seem to return to 

 the same neighbourhood every year."
