rathei" doubt tul, owing to the confusion between the two species of 

 Teal, and ii sliould perhaps be classed as a visitor. 



cSj. Grey Teal. Settinm ^ihhenfrons {Virago gibberifrons). — Resident. 

 Probably commoner than the preceding, but it seems impossible to 

 differentiate it salisfactorilv. 



83. Australian Shoveller. S/^a/it/d ritynchotis. — Resident. One of 

 the rarer Ducks, wliicli jx-rhaps ought to be regarded only as a visitor. 



84. Freckled Duck. Slictonetta nervosa. — Resident. The same 

 remark aijplics as to tlie preceding. 



85. White-eyed Duck. Nyroca australis. — Resident. A fairly 

 common species, which breeds as near Perth as Monger's Lake. 



86. Blue-billed Duck. Erismaiura australis (Oxyura australis). — 

 Resident. Apparently less common than formerly, but has been 

 known to breed a I Herdsman's Lake. 



87. Musk-Duck. Biziiira lohata. — Resident. Very plentiful on all 

 the swamps. 



88. Black Cormorant. Phalacrocorax carbo (P. c. novcBhollandiee). — 

 Resident. Common on lakes and the fresh-water stretches of the 

 rivers ; less freciuent on the salt-water estuaries, and rarely seen on 

 the coast. 



89. Little Black Cormorant. Phalacrocorax siilcirostris (Mesocarbo 

 ater . — Resident. Common on the swamps and estuaries, and much 

 more sociable than the preceding. Rarely seen on the coast. 



90. Pied Cormorant. Phalacrocorax hypoleucus {Hypoleucus varius 

 hypoleticus). — Resident. This is the common Shag of the sea-coast 

 and salt-water portion of the estuaries. It breeds in large numbers 

 on a number of the rocky islets adjacent to Rottnest and Garden 

 Islands and along the coast farther south. 



91. Little Pied Cormorant. Phalacrocorax melanoleucus (Microcarbo 

 melanoleuciis,. — Resident. The commonest species of Shag on fresh 

 water ; also common on the estuaries, and frequently met with on 

 the sea coast. 



92. Australian Darter. Plotus novcs-hollandics (Anhinga novce- 

 Jiollandice). — Resident. Birds of this species are almost always to 

 be seen on the reaches of the Swan p.iver above Perth as well as on 

 the neighbouring swamps. 



93. Australian Gannet. Sula australis (Morns serrator dyotli). — 

 Winter visitor. A few appear off the coast in winter, when they 

 may usually be seen in Cockburn Sound. 



94. Greater Frigate-Bird. Tachypetes aquila {Fregata a. palmerstoni). 

 — Occasional visitor. A specimen captured alive at Perth in May, 

 1917, is the only record for this species {Emu, xvii., p. 238). 



95. Australian Pelican. Pelecanus conspicillatus (Catoptropelicanus 

 c. westralis). — Resident. Common on the Swan River and on the 

 fresh-water swamps of the district, also sometimes .seen on the sea 

 about the islands. It is not known to breed in the district, but 

 probably only a proportion of the birds breed each year, going north 

 for the purpose. 



96. Swamp-Hawk. Circus goiildi (C. approximans. sub-sp. ?). — 

 Resident. One of the commonest Hawks in the disiricl, to be seen 

 in the neighbourhood of all the swamps.
