Haliastur sphenurus {H. spheniivus). Whistling Eagle. — Occasional 

 on the Claudie, but plentiful on the Archer River. 



Milvus afnnis {Milvus korschiin korschun). Allied Kite. — Occasion- 

 ally seen flying high on the Archer River. 



Lophoictinia isura. Square-tailed Kite. — A few were seen on the 

 Archer River, and one specimen was obtained. 



Gypoictinia melanosternon (Gypoictinia melanostevna melanosterna). 

 — Wc saw only a few of these birds on the Claudie. Mr. M'Lennan 

 found them on both the Archer and Watson Rivers. 



Elanus axillaris {E. axillaris axillaris). Australian Black-shouldered 

 Kite. — 'Sir. ^M'Lennan noted a pair on the Watson River. 



Baza subcristata. Crested Hawk. — On the 17th November we 

 had crossed a stretch of grass land, and were entering a strip of tall 

 paper-bark trees, when we disturbed a pair of Hawks unfamiliar to 

 us ; the binoculars, however, enabled us to settle their identity. 

 Very soon one returned to a small nest high up in a tree. On the 

 following day Mr. M'Lennan, using a rope ladder, climbed to the 

 nest, which contained three eggs ; it was placed at a height of 70 feet 

 in a fairly well concealed position. The nest was small comparing 

 it with most Hawks' nests ; it measured 12 inches across the top by 

 5 inches in depth, the egg cavity being 5 inches in diameter by 

 i^ inches in depth. It was composed of dry twigs and branchlets of 

 eucalypts and tea-trees, and lined with green leaves. The eggs, pure 

 white in colour, were slightly incubated. The gizzard of the female 

 contained the remains of a small bird, beetles, and grasshoppers. 



Falco melanogenys {Rhynchodon peregrinus macropus). — We fii'st 

 saw the Black-cheeked Falcon on the day of our arrival at Lloyd's 

 Island, sitting on a termites' mound. On the 12th January, when 

 lying off Lloyd's Island, in the early morning, we watched one 

 stooping at a Lorikeet (Trichoglossus novo'hollandics septentrionalis) ; 

 it missed, and the Lorikeet escaped by dodging past our cutter. The 

 Falcon then turned his attention to another Lorikeet, which also 

 avoided him by rising high in the air. Mr. M'Lennan, previously to 

 our visit, had seen this Falcon kill a Pigeon and fly off with it to a 

 small island in the bay. 



Falco lunulatus. — The Little Falcon was several times noted on 

 the Claudie and Archer Rivers. 



Hieracidea occidentalis (leracidea berigora berigora). — The Striped 

 Brown Heiwk was noted on several occasions on the Claudie and 

 Archer Rivers. 



Pandlon leucocephalus (Pandion haliastur cristatus). — When at the 

 Hannibal Islands, in June, 191 3, Mr. M'Lennan saw a pair of White- 

 headed Ospreys circling round, and found their empty nest in a 

 bushy tree at the edge of the scrub. 



On the ist July, on the Macarthur Islands, Mr. IVI'Lennan noted : — 

 " Did one of the coral ridges before dark ; found an Osprey's nest in 

 the same mangroves as in 191 1. It now contained three eggs. 

 Another nest in a mangrove contained one fully-fledged young one." 



We noted this species on the Claudie River, over Lloyd's Island, 

 and at Haggerstone Island. Mr. M'Lennan noted two pairs at the 

 mouth of the Archer River,
