Pandion leucocephalus. Osprey. — Ospreys breed in several places 

 on Dirk Harlog. notably near Notch Point and at the South Passage. 

 Some of the nests, from being used year after year, have attained a 

 considerable size. I photogaphed one nest in si/it. but this was 

 robbed during my absence at the Ten-mile well. I could not trace 

 who had taken the eggs. I fear they were only destroved. Other 

 pairs breed around Peron Peninsula. I often saw Ospreys perclicd 

 on the masts of the luggers at anchor at Denham. 



Ninox ocellata. ^larbled Owl. — A non-breeding bird was shot at 

 the West well. It appeared to be a stray. It was observed, at 

 intervals, for some weeks perching on the top rail of a fence. 



Euphema petrophila. Rock-Parrakeet. — According to Mr. T. 

 Carter, this species occurs on Dirk Hartog and also on Slope Island. 

 He gives an interesting account of a visit to the latter locality in the 

 Government cutter Shark. Rock-Parrakeets were seen, but no nests 

 found. I searched the whole of the Quoin Bluff and also Notch 

 Point for this species, but absolutely without success. Mr. Carter 

 states that it is found on Peron Peninsula too. 



Eurostopodus guttatus. Spotted Nightjar. — I saw nothing of this 

 Nightjar during cither visit to Shark Bay, but Mr. G. C. Lloyd found 

 an undoubted egg on one occasion. I am inclined to regard it as a 

 casual visitor to Dirk Hartog Island. 



Cypselus pacificus. White-rumped Swift. — Mr. Carter observed 

 'this species at Denham, 13th January, 191 7. 



Cuculus pallidus. Pallid Cuckoo. — ^Ir. Carter includes the Pallid 

 Cuckoo in his list of birds seen on Dirk Hartog ; but only a single 

 example was met with. I, too, found it very uncommon. One 

 individual was heard calling in the earlv mornings for several weeks 

 at the West well. 



Chalcococcyx basalis. Narrow-billed Bronze-Cuckoo. — Not very 

 much in evidence at Shark Bay ; but at Dirk Hartog I found its egg 

 in Black-and-White Wren- Warblers' {Malurus lencopterus) nests on 

 two occasions. I also procured a fully-fledged young bird in Septem- 

 ber at the Ten-mile well. 



Hirundo neoxena. Welcome Swallow. — Common at Shark Bay. 

 On Dirk Hartog breeding at the homestead, and also in the boundary- 

 riders' huts, and even on the sides of the rocky water-holes. ]\Iany 

 haunt the faces of cliffs. 



Petrochelidon nigricans. Tree-^Iartin. — Seen on Dirk Hartog, 

 probably migrating, 



Clieram(Bca leucosternum. White-backed Swallow. — A pair or 

 two breed in the sandy cliffs near Denham. A nest I examined second 

 week in October contained four voung birds, which flew out as I 

 enlarged the tunnel. 



Melanodryas picata. Hooded Robin. — A few pairs on Dirk Harlog 

 and also on Peron were breeding. 



Petroica goodenovii. Red-capped Robin. — A male, in full plumage, 

 and a seccnul one. not fullv adult, were seen perched on bushes and 

 iiUerifig the lainiliar call near tiic Ten-mile well ; probably only 

 casual \isilc)rs. 



Rhipidura preissi. Western Fantail. — Seen by Mr. T. Carter in 

 the mangroves on Peron Peninsula.
