Yellow-throated Miner Kalbarri Pilbara Western Australia

Yellow-throated Miner

“But territorial possession can be more extreme than this. Two honeyeaters of large size practise the most intense resource defence of any birds on earth” – Tim Low, Where Song Began The Yellow-throated or Dusky Miner (Manorina flavigula) is one of the four colonial and co-operatively breeding honeyeaters in the genus Manorina. Closely related to the Black-eared (Manorina melanotus), Bell (Manorina melanophrys) and Noisy Miner (Manorina melanocephala) it breeds communally, with breeding pairs often assisted by other members of the group. Yellow-throated Miners inhabit dry forests and woodlands across Australia, foraging on insects, fruits and nectar, and although not as aggressive and troublesome as Bell and Noisy Miners, they defend their territory and food sources fiercely against any intruder.

Brown Falcon Dales Gorge Karijini Pilbara Western Australia

Brown Falcon

Dales Gorge, or Ngirribungunha, is one of the most popular gorges in Karijini, not only due to the vicinity of the Park’s campground, but mainly because Circular Pool, Fortescue Falls and Fern Pool are hidden between its towering walls. However, less popular but equally exciting is the rim walk, a trail that leads through the Pilbara savannah along the edge of the gorge. With a bit of luck the elusive Rothschild Rock-wallaby (Petrogale rothschildi) can be spotted here around dusk and dawn, or some of the park’s many bird species such as this Brown Falcon (Falco berigora), perching on the branch of a dead snappy gum looking for rodents and reptiles.

Crested Pigeon Karijini Pilbara Western Australia

Crested Pigeon

“The chasteness of its colouring, the extreme elegance of its form, and the graceful crest which flows from its occiput, all tend to render this Pigeon on of the most lovely members of its family, and it is therefore to be regretted that, owing to its being exclusively an inhabitant of the plains of the interior, it can never become an object of general observation.” – John Gould, Handbook to the Birds of Australia, 1865

Tawny Frogmouth Podargus strigoidus Karijini National Park Pilbara Western Australia

Tawny Frogmouth

“Yet something. Something big and aware and hidden! He walked on, had walked a mile or so in the bush, and had just come to a clump of tall, nude, dead trees, shining almost phosphorescent with the moon, when the terror of the bush overcame him.” – D.H. Lawrence, Kangaroo (1923) While the wet season in the Pilbara can be extremely hot, winter is the most suitable time to visit this beautiful region. We unfortunately experienced unusual high rainfall the week prior to our trip, and during our stay in Karijini National Park a cold and unpleasant easterly desert breeze brought temperatures to near freezing after sunset. For nearly five days, the constant wind was almost the only movement we experienced in and around our camp; no snakes, lizards, or dingoes to be seen, and even the region’s rich avian fauna seemed to be in silent hibernation. As campfires aren’t allowed in the park, water bottles, blankets and early nights were our solace, but not after the routine of a late walk in this silent bush. …

Termite mound Karijini National Park Pilbara Western Australia

Termites – Grazers of the Savannah

In 1896 David Wynford Carnegie crossed the Gibson and Great Sandy Desert in search of good pastoral and gold-bearing land. In his account of the expedition, named Spinifex and Sand, Carnegie wrote of the landscape of this largely unexplored land: “There are two varieties of Spinifex known to bushmen – “spinifex” and “buck” (or “old men”) spinifex. The latter is stronger in the prickle and practically impossible to get through, though it may be avoided in twists and turns. There are a few uses for this horrible plant; for example it forms a shelter and its roots make good food for the kangaroo, or spinifex rat, from its spikes the natives (in the northern districts) make a very serviceable gum, it burns freely, serves in a measure to bind the sand, and protect it from being moved by the wind, and makes a good mattress when dug up and turned over.” The spinifex in Karijini (Triodia pungens) plays an important role in the arid ecosystem of the Park, being part of vast tussock grasslands that alternate with Accacia shrubland and open Eucalypt woodlands. As …

Brolgas Roebuck Plains Station Broome Western Australia

Brolga

The Broome Bird Observatory offers tours in the different habits of Yawuru country, showcasing the enormous variety of birds in this beautiful corner of WA. I joined the tour to the saline grasslands, saltmarshes and claypans of Roebuck Plains Station, an iconic Kimberley property that covers 275,000 hectares and is home to 20,000 head of cattle. During the wet season the inundated plains are green and lush, abundant with fish, crabs and frogs, an enormous food bowl for thousands of water birds, but in the dry dust devils sweep through the vast open space, where water is only a memory of different times. The majority of birdwatchers who join this tour are in search of the Yellow Chat (Epthianura crocea), a strikingly coloured passerine bird that can be seen on the plains relatively easy, and as it is one of the must-see species, the Broome Bird Observatory even runs the specific Yellow Chat twitch. I had some good views of this marvellous little bird through the telescopes provided, but unfortunately haven’t been able to get …

Agile Wallaby Broome Bird Observatory Western Australia

Agile Wallaby

After a very dry wet season, the bush surrounding the Broome Bird Observatory looked brown and dry. The sandy soils of this part of the Kimberley are dominated by Coffee Fruit (Grewia breviflora), Helicopter Trees (Gyrocarpus Americanus) and Broome Pindan Wattles (Acacia eriopoda), with diffused tufts of Spinifex grass in the understory. Although this habitat offers most abundant food in the wet, opportunistic feeders as the Agile Wallaby (Macropus agilis) are perfectly able to broaden their diet by shifting to alternative food resources, such as fruits, leaves and roots from other plants: the tracks that can be found on the beach every morning show those marsupials come to the mangroves to feed on propagules during the night. But Agile Wallabies are not the only creatures that harvest the beach after dark. Every morning before the sun rises, thousands of Land Hermit Crabs or irramunga (Coenabita variabilis) commute between beach and bush after the collection of their newly found homes. A journey that many are not likely to survive when crossing Crab Creek road – a journey …

Green Tree Frog Yawuru Conservation Area Broome Western Australia

Green Tree Frog

When visiting the Broome Bird Observatory, it’s hard to miss the resident wildlife that gathers in and around the camp’s ablution blocks; from the highly venomous King Brown Snake (Pseudechis australis) to the harmless Stimson’s Python (Antaresia stimsonia), some of Australia’s notorious reptiles are drawn to this place to hunt Green Tree Frogs (Litoria caerulea). These ever smiling and relaxed amphibians love to live in toilet bowls – hence its nickname Dunny Frog – during the dry season, when water in the bush is scarce. Although it was easier to find them when flushing, the sight of the dust covered tree-climber was well worth the spotlighting effort.

Rainbow bee-eater Roebuck Bay Broome Western Australia

Life in the mangroves

When descending the red Pindan cliffs towards the beach and benthic flats of Roebuck Bay, one comes across several mangals and tidal creeks. The tropical mangrove forests near Broome consist of several species, such as the common grey mangrove (Avicennia marina), stilt-rooted mangrove (Rhizophora stylosa) and the red mangrove (Ceriops tagal) or lanyi-lanyi. Those forests are complex and rich habitats that require much specialization to live in, and many animals found in the mangroves are therefore absent or rare in other places. With their bright red colour, flame fiddler crabs (Uca flammula) are the most beautiful crabs of the mangroves by far. The typical big and oversized claw of this mostly vegetarian crustacean is waved to defend their territory rather than to crush food, while their remarkable appearance is further enhanced by eyes positioned on tall stalks, enabling them to detect threats from afar so they can disappear in their burrow quickly. The Mangrove mudskipper is another conspicuous creature that can be found in Roebuck’s mangroves. Because they are able to breath through their skin …

Red Wattlebird Anthochaera carunculata Lake Herdsman Western Australia

Red Wattlebird

With grevillea, hakea and eucalypts flowering in abundance, different species of honeyeaters (Meliphagidae) can be found feeding on their nectar. With thin curved bills and brush-like tongues, they’re probing flowers and lapping up large quantities of sweet liquid at a time. Most members of diverse family of passerine birds can be found in Australia and New Guinea, with the Red Wattlebird (Anthochaera carunculata) or Djoongong the largest species in Western Australia. The distinctive red-pink wattles or caruncles have lend this bird its common name, and as one of the noisiest inhabitants of our urban bushland they’re hard to miss when chasing away other nectar-feeding birds as lorikeets and parrots.    

Glossy Ibis Plegadis falcinellus Lake Herdsman Western Australia

Glossy Ibis

Rain is plentiful now Makuru is in full swing, but cool and wet days alternate with dry and sunny ones, leaving ample time to explore nature. As the rains have steadily raised water levels of lakes and swamps, large flocks of birds aggregate on its waterlogged shores, offering excellent opportunities for bird photography. On the Swan Coastal Plain a chain of wetlands runs parallel to the coast; many small ones have been drained, filled or cleared in the past for agricultural and urban development, but Herdsman Lake is the biggest still remaining. Known as Ngurgenboro to the Yellagonga Noongar, the lake is not only a place with a significant cultural heritage, it is also one of the last remaining wildlife havens in the metropolitan area. Apart from a strong supply of reptiles, including the notorious Tiger Snake (Notechis scutatus), over 100 bird species have been recorded at Herdsman Lake. Waterbirds are particularly visible, amongst which the Black Swan, Yellow-billed Spoonbill, Nankeen Night Heron and Australian Shelduck I have written about before. The Ibis family is represented with …

Nankeen Night Heron Nycticorax caledonicus Lake Herdsman Western Australia

Nankeen Night Heron – Ngalganin

“When perched on the trees or resting on the ground, it exhibits none of the grace and elegance of those birds, its short neck resting on the shoulders” – John Gould, Handbook to the Birds of Australia, volume 2 As their name suggests, Nankeen Night Herons (Nycticorax Caledonicus) stalk marches and wetlands during the dark hours of the day, searching for insects, crustaceans, frogs and fish. During daytime these stocky herons can be found roosting, heads hunched onto the shoulders, in the dense canopy of the numerous Swamp Paperbark (Melaleuca rhaphiophylla) trees that surround Lake Herdsman. Although this colony counts between 20-30 individuals, none of those secretive birds leave the thick cover easily, making decent photography a job for the patient. Apart from its nocturnal character, the cinnamon-brown colour has contributed to the other part of its name, as Nankeen cloth from Nanking resembles the adult bird’s plumage.

Tiger Shark Shark Bay Western Australia

Tiger Shark Feeding Frenzy

Last October we were privy to see some fascinating Tiger Sharks (Galeocerdo cuvier) when sailing with the awesome crew of Monkey Mia’s Shotover. This seems a redundant comment to make when Shark Bay is renowned for it’s big population of those undiscerning predators, but whenever they got close to the boat shivers of excitement ran through the crowd. Imagine how the plethora of sharks feeding on the carcass of a humpback whale off Steep Point last Friday must have left the people on those two boats in awe! The shared footage is filmed with a drone by Eco Albrolhos  – please watch the final part of the clip and be convinced that a GoPro is a handy tool in those situations.

Australian Shelduck Tadorna tadornoides Herdsman Lake Western Australia

Australian Shelduck – Guraga

The Australian Shelduck (Tadorna tadornoides) is a gorgeous water bird. Its black head is separated from its beautiful chestnut coloured breast by a white ring, making it one of the easiest recognisable duck species in our wetlands. Shelducks are true wanderers, travelling long distances between the coastal lakes and estuaries and the inland Wheatbelt, however, some stay to breed in the metropolitan area during the winter months, such as this couple at the banks of Lake Herdsman. They pair for life, and the white eye-ringed female is constantly guarded by a watchful male – true love.

Yellow-billed Spoonbill Platalea flavipes Herdsman Lake Western Australia

Yellow-billed Spoonbill

One of the most unusual residents of the Swan Coastal Plain wetlands is the Yellow-billed Spoonbill (Platalea flavipes). Instead of relying on eyesight  when foraging for invertebrates in deep and muddy water, the spatula-shaped bill is equipped with papillae that detect vibrations of prey. It can often be seen walking slowly through the water, sweeping its beak from side to side in search for insects, crustaceans and fish, or just perching on a branch of a Swamp Paperbark tree (Melaleuca rhaphiophylla), such as this one on the banks of Herdsman Lake.

Welcome Swallow Hirondu neoxena Herdsman Lake Western Australia

Welcome Swallow – Kannamit

Perching on the branch of a dead Paperbark tree, this Welcome Swallow (Hirundo neoxena) is waiting to swoop down on the clouds of mosquitos that appear around dusk near the banks of Lake Herdsman, one of the most important wetland areas on the Swan Coastal Plain. The Welcome Swallow is called Kannamit by the Noongar people, who believe this fast and acrobatic bird is a sign of imminent rain.

Eastern Great Egret Canning River Western Australia

Eastern Great Egret

The Swan River Estuary is the centrepiece of Perth. It’s a place of great cultural importance for the Whadjuk people, who believe the Swan River (Derbal Yerrigan) and its tributary, the Canning River (Djalgarra), were made by the dreaming serpent Waugal, creator of rivers, lakes and other landforms on its journey to the Indian Ocean. The same rivers offer recreational activities such as sailing, kayaking or scuba-diving to most city dwellers, while for me the surrounding trails, magnificent views and prolific wildlife are the biggest drawcards. From Indo-Pacific bottlenose dolphins (Tursiops aduncus), Western Australian sea horse (Hippocampus angustus) colonies, marine and estuarine fish to a huge variety of waterbirds, the biodiversity of this unique ecosystem is astounding. Photo-opportunities galore, like this portrait of an Eastern Great Egret (Ardea modesta) waiting on the shores of the Canning River jabbing at fish and frogs with its dagger-shaped beak.  

Black Swan Cygnus atratus Canning River Western Australia

Black Swan – New Holland Novelty

“…en oock geen sonderling gedierte of gevogelte daer ontwaert, als ten principale in die Swaene rivier een soort van swarte swaenen, daer aff er oock drie levendigh tot ons gebragt hebben en wij UEd. gaarne hadden toe gestuurt, maar sij sijn alle een voor een korts naer hun herwaerts comste gestorven” – Iets over de reis van den schipper-commandeur Willem de Vlamingh, naar Nieuw Holland, in 1696 The first black swans (Cygnus atratus) were observed in January 1697 by Dutch explorer Willem de Vlamingh when venturing on a just discovered river in Western Australia. The black swans were a novelty, as back in those days everyone thought swans were white. The spooked expedition returned to the coast after this unsettling encounter, and baptised the river Swarte Swaenen Rivier (Swan River). The three swans taken on board of the vessels died before the end of the journey, however, a century later French explorer Baudin was more successful, bringing back those beautiful black birds to adorn the imperial gardens of Chateau de Malmaison.
