Ephthianura tricolor (Tri-coloured Bush-Chat).—A few pairs met with on the sand plains west of Mogumber; they were all adults; probably returning migrants.
Gymnorhina leuconota[1] (White-backed Magpie).—Pretty common from Mogumber to New Norcia; but to the westward rather rare. At the former locality I saw several nests.
Cracticus destructor (?) (Butcher-Bird).—I observed pairs of Cractius in many places up and down the river. I think they were referable to this species, but am not absolutely certain.
Pachycephalus occidentalis.—Found in the thicker scrubs, but far from plentiful.
Climacteris rufa (Rufous Tree-creeper).—Not uncommon amongst the eucalypts.
Sittella pileata (Black-capped Tree-runner).—Little parties often seen, both up and down the river.
Myzomela nigra (Black Honey-eater).—A few met with in open country sparsely clothed with dwarfed banksias, not far from the junction of the north branch of the river.
Acanthorhynchus superciliosus (White-browed Spinebill).—As far as I could see, this beautiful species was absent from the immediate neighbourhood of Mogumber and the country to the east. I first encountered it 10 miles down the river, and more commonly still further to the west. It seemed partial to the oases of banksia and the scrub verging on the sand plains.
Zosterops gouldi (Green-backed White-eye).—Common, and breeding throughout the course of the river.
Glycyphila fulvifrons (Fulvous-breasted Honey-eater).—A few pairs on the slopes of a range of hills to the north of Mogumber. To my surprise it was absent from the sand plains.
Glycyphila ocularis (Brown Honey-eater).—Common in all suitable localities.
Manorhina obscura (Dusky Miner).—A few parties met with near Mogumber.
Acanthochæra Carunculata (Red Wattle-Bird).—Pretty common, both up and down the river.
Pardalotus ornatus (Red-tipped Pardalote).—Common amongst the eucalypts.
Hirundo neoxena.—A few pairs generally met with around homesteads. I was told of colonies of either this species or Petrochelidon ariel breeding in the culverts of the railway line some few miles away.
Petrochelidon nigricans (Tree-Martin).—Common, and breeding in many places amongst the white gums.
Petrochelidon ariel (Fairy Martin).—I did not actually see this species, but photographed a group of nests in a recess of a limestone cliff, about three miles west of Mogumber. They were probably nests of the previous year.
Anthus australis (Pipit).—Not uncommon on the sand plains and in open country.
