13. HiERACIDEA ORIENTALIS, Schl. 



Rarely visit the district, but when they do are very numerous. 



14. TiNNUNCULUS CENCHROIDES, Vig. & HoTS. 



Usually nests in hollow spouts and sometimes in deserted nests. 



15. Strix flammea, Z., suh-sp. delicatula. 



A specimen shot by the late Mr. H. Thurston is in the reading- 

 room of the Mechanics' Institute, Mudgee. They are said to be 

 plentiful in the orchard at Puttabucca when the fruit is ripe. 

 Probably the windfalls attract mice, and the owls follow. We 

 have also a specimen from Coolah. 



16. NiNOX BOOBOOK, Lath. 



A very common bird, breeding in hollow trees. Its booming 

 cry is continually heard in the spring months. 



17. Aegotheles Nov^-Hollandi^, Lath. 



We have shot three specimens all differing much in colour from 

 Gould's figure, being dull ashy-greys without the warm tints 

 shewn in figure alluded to. Eggs December 7th. 



18. Pod ARGUS strigoides, Lath. 



Breeds in spring and early summer. We have taken eggs 

 October 4th to 15th November, and seen them sitting on the 

 unfledged but downy young on November 15th. 



It is probable that we have more night-birds than the above four 

 species. We have certainly seen Eurostopodus guttatus, but 

 having failed to shoot it, we have not included it in this list. 



19. CHiETURA caudacuta. Lath. 



A regular visitant. We have observed flocks in January, 

 February, March, April, July, August, and December. 



20. Cypselus pacificus. Lath. 



We have seen this bird only in among the flocks of Choetura.
