ICINGHORN, Trip to Upper Colo [’Jf oT 
Notophoyx pacifica. White-necked Heron.—One pair was seen, and 
several were heard in the swamps at the back of Upper Colo. 
Nycticorax caledonicus. Nankeen Night Heron.—Plentiful, both on 
the Hawkesbury and Colo Rivers, but most numerous round about 
the swamps and lagoons at Upper Colo. 
Butorides striata. Little Mangrove Heron.—One pair seen on the 
eastern swamp at Upper Colo. 
Anas superciliosa. Grey (Black) Duck.—A flock of about twelve 
inhabited the eastern swamp at Upper Colo. 
Phalacrocorax varius. Pied Cormorant. — Several pairs were seen 
at Upper Colo. 
Phalacrocorax carbo. Black Cormorant. — A few specimens were 
seen on the Hawkesbury River, and flying overhead at Wheeny Creek. 
They were plentiful at Upper Colo, where they preferred the western 
swamp. 
Circus approximans. Swamp Harrier.—Only a few birds were 
seen during the whole trip. Some were hovering over the flats near 
the river at Richmond, while the others were seen over the flats 
at Upper Colo. 
Astur fasciatus. Australian Goshawk. — Fairly plentiful at every 
place we visited with the exception of Wheeny Creek. 
Astur cirrocephalus. Collared Sparrowhawk.—Plentiful on the flat 
country around Richmond and on the ridges along the Comleroy 
road, but only about two pairs were seen at Upper Colo. 
Uroaetus audax. Wedge-tail Eagle.—We did not count them, but 
they could be seen hovering high in the air almost any time we cared 
to lock for them at any stage of the journey. 
Haliastur sphenurus. Whistling Eagle. — Flying overhead at Rich¬ 
mond and Comleroy. 
Elanus axillaris. Australian Black-shouldered Kite. — Several pairs 
were seen hovering over and diving into the fields at Upper Colo. 
Tyto alba. Barn Owl. — A few were heard at night at Upper Colo. 
Ninox boobcok. Boobook Owl.—Heard at night at Upper Colo. 
Glossopsitta concinna. Musk Lorikeet. — Several specimens which 
we considered to be this species flew quickly overhead at Upper Colo. 
Calyptorhynchus funereus. Black Cockatoo. — One pair was seen by 
Mr. Wright in the thick scrub and forest at Wheeny Creek. 
Kakatoe galerita. White Cockatoo. — A flock containing between 
twenty and thirty birds flew over our camp at Upper Colo and settled 
in a corn patch and in some trees a few hundred yards along the 
river bank. 
Aprosmictus scapularis. King Parrot.—While these birds were not 
plentiful during our visit, a pair was seen in the bush along the 
river at Upper Colo. The children of the district regard this species 
as being quite common. 
Platycercus elegans. Crimson Rosella. — One pair seen at Upper 
Colo. 
Platycercus eximius. Eastern Rosella. — In great numbers through¬ 
out the country. 
Lathamus discolor. Swift Parrot.—A few birds which we thought 
to be this species were seen flying about in the bush, but we were 
never able to get near enough to confirm our identification. 
Podargus strigoides. Tawny Frogmouth. — Fairly numerous around 
Upper Colo. A pair, which we did not attempt to disturb in any 
way, lived in a river oak which shaded our tent; we noted that the 
female spent most of her time sitting on her nest.
