The Solomon Islands
THE SOLOMON ISLANDS 14 SEPTEMBER – 7 OCTOBER 2007 TOUR REPORT LEADER: MARK VAN BEIRS Rain, mud, sweat, steep mountains, shy, skulky birds, shaky logistics and an airline with a dubious reputation, that is what the Solomon Islands tour is all about, but these forgotten islands in the southwest Pacific also hold some very rarely observed birds that very few birders will ever have the privilege to add to their lifelist. Birdquest’s fourth tour to the Solomons went without a hiccup. Solomon Airlines did a great job and never let us down, it rained regularly and we cursed quite a bit on the steep mountain trails, but the birds were out of this world. We birded the islands of Guadalcanal, Rennell, Gizo and Malaita by road, cruised into Ranongga and Vella Lavella by boat, and trekked up into the mountains of Kolombangara, Makira and Santa Isabel. The bird of the tour was the incredible and truly bizarre Solomon Islands Frogmouth that posed so very, very well for us. The fantastic series of endemics ranged from Solomon Sea Eagles, through the many pigeons and doves - including scope views of the very rare Yellow-legged Pigeon and the bizarre Crested Cuckoo- Dove - and parrots, from cockatoos to pygmy parrots, to a biogeographer’s dream array of myzomelas, monarchs and white-eyes. A total of 146 species were seen (and another 5 heard) and included most of the available endemics, but we also enjoyed a close insight into the lifestyle and culture of this traditional Pacific country, and into the complex geography of the beautiful forests and islet-studded reefs. -
Tawny Frogmouth (Podargus Strigoides)
Bush B Volume 1 u d d i e s Tawny Frogmouth (Podargus strigoides) When it’s not mistaken for an owl, the Tawny Frogmouth can easily be confused with a tree branch! With narrowed eyelids and a stretched neck, this bark-coloured bird is a master of camouflage. Tawny Frogmouths are between 34cm (females) and 53cm (males) long and can weigh up to 680g. Their plumage is mottled grey, white, black and rufous – the feather patterns help them mimic dead tree branches. Their feathers are soft, like those of owls, allowing for stealthy, silent flight. They have stocky heads with big yellow eyes. Stiff bristles surround their beak; these ‘whiskers’ may help detect the movement of flying insects, and/or protect their faces from the bites or stings of distressed prey (this is not known for certain). Their beak is large and wide, hence the name frogmouth. Their genus name, Podargus, is from the Greek work for gout. Why? Unlike owls they don’t have curved talons on their feet; in fact, their feet are small, and they’re said to walk like a gout-ridden man! Their species name, strigoides, means owl-like. They’re nocturnal and carnivorous, but Tawny Frogmouths aren’t owls – they’re more closely related to Nightjars. There are two other species of frogmouth in Australia – the Papuan Frogmouth (Podargus papuensis) lives in the Cape York Peninsula, and the Marbled Frogmouth (P. ocellatus) is found in two well-separated races: one in tropical rainforests in northern Cape York and the A Tawny Frogmouth disguised against the bark of a tree at Naree in NSW. -

First Field Observation of Karimui Owlet-Nightjar Aegotheles Bennettii
Markus Lagerqvist et al. 95 Bull. B.O.C. 2017 137(2) First feld observation of Karimui Owlet-Nightjar Aegotheles bennetii terborghi by Markus Lagerqvist, Ashley Banwell & Roger McNeill Received 18 September 2016; revised 4 May 2017; published 18 June 2017 htp://zoobank.org/urn:lsid:zoobank.org:pub:E2EAC3D3-100E-4928-9AFA-1C9D8E6DDF9D Summary.—The owlet-nightjar Aegotheles bennetii terborghi was described from a single male specimen given by a local man to Jared Diamond, while he was collecting in the Karimui Basin in the Eastern Highlands of Papua New Guinea, in 1964. There has been no further observation of the taxon, despite extensive feld work in 2011–12. In July 2016 we travelled to Karimui with the explicit aim of searching for this taxon, which resulted in the frst-ever feld observation, including photographs and a possible sound-recording of its call. Originally described as a subspecies of Barred Owlet-Nightjar Aegotheles bennetii terborghi, based on its similarity to the two mainland races—the nominate in southern New Guinea and wiedenfeldi in northern New Guinea—A. b. terborghi difers mainly in its much larger size—male wing 154 mm vs. 114–128 mm, and tail 142 mm vs. 99–110 mm in the other two subspecies of A. bennetii (del Hoyo et al. 2017). It is also described as having much darker, blacker upperparts, with the white speckling on the back and upperwing- coverts being somewhat more distinctly organised into a regular transverse (barred) patern (Diamond 1967, Holyoak 1999). However, there is considerable variation within the other subspecies of A. -

The rare Black-faced Pitta posed so well on Santa Isabel, right at the edge of the pitta world range! All photos by Joshua Bergmark. SOLOMON ISLANDS 8 AUGUST – 3 SEPTEMBER 2019 LEADER: JOSHUA BERGMARK 1 BirdQuest Tour Report: Solomon Islands 2019 www.birdquest-tours.com Magnificent, but often skulking birds. Mud, sweat, extended slippery treks, steep mountains, shaky logistics, and constant battles with land access. This is what a Solomon Islands tour is all about, but these sleepy forgotten islands in the southwest Pacific hold some glorious, very rarely observed birds that very few birders will ever have the privilege to add to their lifelist. The Solomon Islands comprise Endemic Bird Areas 198 and 199, and although the total area of this archipelago is smaller than Belgium (less than 50,000 km2), these rich islands have more restricted range species than any other Endemic Bird Area in the world! Of the Solomons EBA endemics, we amazingly recorded all 70 of the likely species on this route, plus an additional clean sweep of the 13 available Melanesian endemics - hitting 100% of our key targets in this demanding country is certainly a miracle, and surely rates this as our most successful tour yet! Of these specials, just two were heard only, so we were all very pleased indeed. We had fantastic looks at four genera that are endemic to the Solomon Islands: Rigidipenna (Solomons Frogmouth), Nesoclopeus (Woodford’s Rail), Meliarchus (Makira Honeyeater) and Woodfordia (Bare-eyed White-eye), plus enjoyed the easternmost members of two highly desirable families (the cute Solomons Cockatoo and the glorious Black-faced Pitta). -

Blue Bird-of-paradise Tour Summary Our tour of Papua New Guinea began as we boarded our aircraft to the South Pacific islands of the Bismarck Archipelago for the pre-tour extension. First-off, we visited the rainforest of the Pokili Wildlife Management Area which holds the largest breeding colony of Melanesian Scrubfowl in the world. It was an amazing experience to wander through the massive colony of these bizarre birds. We also managed outstanding views of the gorgeous Black-headed Paradise-Kingfisher, Blue-eyed Cockatoo and Red- knobbed Imperial-Pigeon. Some participants were fortunate to spot the rare Black Honey Buzzard. Then we took time to explore several small, remote tropical islands in the Bismarck Sea and were rewarded with sightings of Black-naped Tern, the boldly attractive Beach Kingfisher, Mackinlay’s Cuckoo-Dove and the extraordinary shaggy Nicobar Pigeon. Back on the main island, we visited the Pacific Adventist University, where we found a roosting Papuan Frogmouth, White-headed Shelduck and Comb-crested Jacana. -
A Prolonged Agonistic Interaction Between Two Papuan Frogmouths Podargus Papuensis
Australian Field Ornithology 2017, 34, 26–29 http://dx.doi.org/10.20938/afo34026029 A prolonged agonistic interaction between two Papuan Frogmouths Podargus papuensis C.N. Zdenek1, 2, 3 1Fenner School of Environment and Society, The Australian National University, Canberra ACT 2601, Australia 2School of Biological Sciences, The University of Queensland, St Lucia QLD 4067, Australia 3Address for correspondence: 15 Murrami Court, Tanah Merah QLD 4128, Australia Email: [email protected] Abstract. Papuan Frogmouths Podargus papuensis are large nocturnal birds about which relatively little is known. A prolonged aggressive interaction between two Papuan Frogmouths that involved interlocking beaks was filmed in the Lockhart River region on Cape York Peninsula, Queensland, and is described here. Two additional Papuan Frogmouths were present during the event, one of which gave a call-type (OomWoom) previously unrecorded for this species. Difficulties associated with detecting such agonistic behaviour mean that the prevalence of these contests and their behavioural significance are currently unknown and require further research. Introduction Study area and methods Conflict between conspecifics can be motivated by On 19 August 2015, the observation was recorded at 1856 h territorial dispute, competition for mates, and/or competition in the Lockhart River region on Cape York Peninsula, for resources (West-Eberhard 1983; Begon et al. 2006). Queensland (12°47′S, 143°18′E) (Figure 1). The following Many species have appendages of different forms that equipment was used to film the event: a Canon EOS 5D are used as weapons (e.g. horns, antlers, mandibles) to Mark III camera with a 400-mm (fixed) EF f5.6L IS USM lens secure territories and attract mates (Clutton-Brock & Albon and a directional Rode VideoMic pro external microphone 1979; Kelly 2006), but weaponry is largely absent in birds, (with a windshield; set to 0 dB gain boost). -
Erythrotriorchis Radiatus) and Other Raptors on the Weipa Plateau, Cape York Peninsula
The Sunbird (2014) 44(2): 36–51 SURVEYS OF THE RED GOSHAWK (ERYTHROTRIORCHIS RADIATUS) AND OTHER RAPTORS ON THE WEIPA PLATEAU, CAPE YORK PENINSULA S.J.S. DEBUS & J.B. SEARLE ABSTRACT Surveys for diurnal and nocturnal raptors were conducted in the Weipa area, Cape York Peninsula, in July–August 2012 and July 2013. Diurnal raptors were surveyed by means of vehicle-based road or track transects (some through forest areas) and foot searches in forest (2012: 630 km and 30 hrs of driving, 10 hrs of searching on foot; 2013: 540 km and 10 hrs of road driving, 50 hrs of searching, mostly on foot, within forest). Owls were surveyed by listening, call playback and spotlighting (2012: four evenings, 13 sites; 2013: four evenings, 24 sites). In 2012, 15 diurnal raptor species and one owl species, the Southern Boobook (Ninox novaeseelandiae), were recorded in the survey area. The Red Goshawk (Erythrotriorchis radiatus) and Square-tailed Kite (Lophoictinia isura) were also recorded by a colleague during the 2012 survey period. In 2013, 19 diurnal raptor species, including a Red Goshawk and a Square-tailed Kite, and one owl, the Southern Boobook, were recorded in the survey area. Further observations of Red Goshawks were obtained from the survey area in April and August 2013 and March 2014, and of a pair of Rufous Owls (Ninox rufa) in April 2014. We conclude that the area of Darwin stringybark (Eucalyptus tetrodonta) tall open forest surveyed is an important foraging habitat for between two and five pairs of Red Goshawks, and that the Weipa Plateau contains habitats suitable for Red Goshawk breeding. -
Chapter 3 the Study Species
CHAPTER 3 THE STUDY SPECIES • 52 3.1 Introduction The moist eucalypt forests of the NSW north coast support one of the most diverse assemblages of birds in Australia. A total of 229 species (122 diurnal passerines, 96 diurnal non-passerines, and 11 nocturnals) occur in this region (NSW NPWS 1994a). This represents 53 % of the 430 species of forest-dwelling vertebrates recorded in north-east NSW (NSW NPWS 1994a). The region is a population stronghold for many passerines and some non-passerines and provides important over-wintering habitat for migratory species (NSW NPWS 1994a). The diurnal passerines of these forests include nectarivores (e.g., honeyeaters), frugivores (e.g., orioles, figbirds), granivores (e.g., finches), foliage-, ground- and bark-foraging insectivores (e.g., robins, scrubwrens, flycatchers, thornbills, gerygones, treecreepers), ground-foraging insectivores that rake litter and soil (e.g., Eastern Whipbird, Logrunner and the lyrebirds), and predatory and scavenging species such as butcherbirds, currawongs and crows (NSW NPWS 1994a; Smith et al. 1995). The diurnal, non-passerine forest avifauna of the region include cockatoos, parrots, cuckoos, Australian Brush-turkey Alectura lathami, kingfishers, pigeons, doves and button-quail, and birds of wetlands, waterways and forest edges (e.g., ibis, egrets, rails, bitterns, herons, raptors) that may use forest trees for nesting and roosting (NSW NPWS 1994a). Old tree hollows are used for nesting by cockatoos, parrots and some kingfishers while raptors perch on dead branches and nest in large forks of old trees. Nocturnal forest birds of the region comprise six owl species, including the endangered (in NSW) Powerful Owl Ninox strenua, Sooty Owl Tyto tenebricosa, Masked Owl T. -
The Solomon Islands
The wonderfully bizarre Solomons Frogmouth was the ‘Bird of the Trip’ (Josh Bergmark) THE SOLOMON ISLANDS 6 JULY – 1 AUGUST 2017 LEADER: MARK VAN BEIRS and JOSH BERGMARK 1 BirdQuest Tour Report: The Solomon Islands www.birdquest-tours.com Magnificent, but often skulking birds. Mud, sweat, slippery trails, steep mountains, shaky logistics, and an airline with a dubious reputation. This is what the Solomon Islands tour is all about, but these forgotten islands in the southwest Pacific hold some glorious, very rarely observed birds that very few birders will ever have the privilege to add to their lifelist. Our tour total this year included a great selection and a large percentage of the endemic birds and specialities. The Solomon Islands comprise Endemic Bird Areas 198 and 199, and although the total area of this archipelago is smaller than Belgium (less than 50,000 km2), these rich islands have more restricted range species than any other Endemic Bird Area in the world! Of the Solomons EBA endemics, we recorded 64 of the 68 possible species on this route, plus an additional clean sweep of the 13 available Melanesian endemics. We had good looks at three genera that are endemic to the Solomon Islands: Rigidipenna (Solomons Frogmouth), Meliarchus (Makira Honeyeater) and Woodfordia (Bare-eyed White-eye). This tour is definitely one of our toughest trips through a combination of intense physical effort, unpredictable weather and capricious logistics. The treacherous paths of the Makira hills, the tough hike and overnight high on Kolombangara volcano and the sometimes brutally steep, slippery trails of Santa Isabel will long be remembered by all participants. -
