 and at Fremantle. 



68. White Egret. Herodias syrmatophorus ^H. alba syrmatopliora ).

 apparently becoming commoner, as some now appear about Perth 

 each winter. 



69. White-fronted Heron. Notophoyx novcc-hollandicp. — Resident. 

 ^'crv plentiful on all swamps, w^ater-holes, and streams. 



70. White-necked Heron. Notophoyx pacifica {Myola- pacifica). — 

 Resident. Not so common as the preceding, but especially plentiful 

 in the winter. I'robably the majority leave the district to breed. 



71. Reef-Heron. Demiegretta sacra {Demigretta s. cooktowni).—

 Resident. Common about the rivers and swamps. Formerly a 

 large colony bred in a cave on Bird Island, off Rockingham, but the

 early days, and still to be found on all the larger pieces of water in 

 fair numbers. On..the Swan River it was at one time exterminated, 

 and was re-introduced some years ago by turning loose individuals, 

 some of which had probably come from the Eastern States. 



yj. Wood-Duck. Chlamydochen juhala {Chenonetta jubata). — 

 Resident. One of the rarer Ducks of the district, and should possil)ly

 from time to time. 



78. Whistling-Duck. Dendrocygna arcuata (D. javanica gouldi). — 

 Occasional \'isilor, A bird shot at Wanneroo in 1899 is the only
