Beach Thick-knee
Esacus magnirostris
Large shorebird with an enormous chunky beak, black-and-white-marked face, white stripes on the shoulder, and long and sturdy legs. Unlikely to be encountered anywhere except coastal areas, particularly beaches, reefs, and estuaries; very unusual even a few hundred meters inland from these habitats. Heavy human activity on beaches in certain areas has confined them to small offshore islands. Often calls at night, giving high-pitched piping and whistling notes.
Identification
The beach stone-curlew is 54-56 cm (21-22 in) long. At a mean of 1,032 g (2.275 lb) in males and 1,000 g (2.2 lb) in females, it is the heaviest living member of the Charadriiformes outside of the gull and skua families. They have black and white face patterning, yellow eyes and a grey-brown upper body.

Range and habitat
The beach stone-curlew is a resident of undisturbed open beaches, exposed reefs, mangroves, and tidal sand or mudflats over a large range, including coastal eastern Australia as far south as far eastern Victoria, the northern Australian coast and nearby islands, New Guinea, New Caledonia, Indonesia, Malaysia, and the Philippines. It is uncommon over most of its range, and rare south of Cairns.
- Migration
- Resident species
Behavior
Beach stone-curlew forage on low tide muddy sand for invertebrates, mostly crabs.<p>The bird breeding season is September to November. The bird nests in sand, laying one egg per season just above the high tide line on the open beach, where it is vulnerable to predation and human disturbance. The egg is vulnerable to Both parents care of the young until they reach 7-12 months of age.<p>As an alarm, the bird will make a chwip-chwip to ward creatures away from their territory.

Gray-throated Sunbird
Anthreptes griseigularis
A small bird of lowland wooded areas with a fairly long, slightly curved, stout bill and yellow underparts. Male has a pale gray throat, a dark reddish cheek and wing patch, a purplish-blue forehead and shoulder, and bottle green on the sides of the throat, the back of the neck, and the crown. Female is fairly drab, with a grayish-brown head and an olive-green back and rump. Male unmistakable. Female similar to several other species, but larger, with a broader bill. Voice not well known, but probably gives a loud “whip!” similar to Brown-throated Sunbird.

Madagascar Scops-Owl
Otus rutilus
Typical scops-owl, with small ear tufts that can be hidden, especially when roosting during the day. Color varies from gray to brown to rufous, with rufous birds more prevalent in the eastern rainforest. Inhabits both moist and dry habitats throughout Madagascar, including rainforest, dry deciduous forest, spiny forest, scrub, and plantations. Often found on day roosts in low tangles. Song varies geographically. In the east, it is a punctuated “tru-tru-tru…”. In the west it is a more rolling “trrr-trrr-trrr…”. Intermediate vocalizations can be heard in transitional zones, such as far northern Madagascar. Much smaller than all of Madagascar’s other owls.

Silver-crowned Friarbird
Philemon argenticeps
Large gray honeyeater with pale gray cap, bare black facial skin, and a small but prominent "horn" on the long, pointed, black bill. This species has gray-brown upperparts and dull white underparts; the feathers on the back of the head are paler than those on the back. Take care to distinguish from Helmeted Friarbird (which is browner overall with a rounded upper rear edge to the facial skin). Found in a variety of drier woodland habitats across the Kimberley and the Top End of the Northern Territory. Also found on Cape York in Queensland but not expected in the Cairns/Atherton area. Typically very loud, with a variety of harsh, loud squawks.
