Tropical Queensland is, by most serious assessments, the finest birdwatching destination in Australia. This is not a claim I make carelessly. The Wet Tropics rainforest has the highest bird species density of any region in the country, including seventeen endemic species found nowhere else in the world. The coastal wetlands and estuaries hold enormous concentrations of waterbirds and migratory shorebirds. The offshore islands support seabird colonies of considerable scale. And the interface zones — where the rainforest meets the reef, where the wet tropics meets the dry tropics at the Atherton Tablelands’ edge — produce the kind of species assemblage diversity that birders travel from Europe and North America to experience.
I am not primarily a birder. I come to birds through reef travel, not the other way around. But the birds of coastal Queensland have, over fifteen years, made an increasingly insistent claim on my attention whenever I’m in the region, and I’ve come to think that ignoring them is a significant omission from the reef travel experience.
The Wet Tropics Endemics
The Wet Tropics World Heritage Area has seventeen endemic bird species — birds found only in this specific section of rainforest — and a total bird list exceeding 430 species. The endemics are the primary draw for visiting birders, and they concentrate in several specific locations.
Atherton Tablelands is the most consistently productive area for wet tropics endemics. The upland lakes, the rainforest patches, and the adjacent eucalypt woodland along the tablelands’ edge collectively support most of the endemic species list. The Golden Bowerbird (Prionodura newtoniana) — a small, remarkable bird whose male constructs a bower decorated with pale objects and maintains it for years — occurs in upland rainforest above 900 metres; the Atherton Tablelands has the most accessible populations. The Tooth-billed Catbird (Scenopoeetes dentirostris), the Fernwren (Oreoscopus gutturalis), and the Chowchilla (Orthonyx spaldingii) — a large, loud, ground-foraging bird that produces one of the most distinctive calls in the Australian rainforest — are all reliably found in tablelands locations with appropriate habitat.
Crater Lakes National Park (Lake Eacham and Lake Barrine) gives access to rainforest birding in the tablelands’ most intact vegetation. Dawn walks around the lakes before the tourist boats begin their circuits produce the quiet conditions that make forest birds findable: following calls, waiting at fruiting trees, sitting at the lake edge while the dawn chorus organises itself from the canopy above.
Mount Lewis Road, a forestry track climbing into the highest sections of the tablelands’ eastern escarpment, is the site for several difficult-to-find endemics including the Blue-faced Parrot-finch and the Grey-headed Robin.
Seabirds and Offshore Islands
The offshore islands of the GBR and the Coral Sea support seabird colonies of considerable interest, though access is more difficult than for mainland sites.
Michaelmas Cay, accessible on day trips from Cairns, is one of the most accessible GBR seabird nesting sites. The cay hosts a colony of crested terns, sooty terns, brown noddies, and the occasional large frigatebird passing through. The density of birds on the cay during nesting season, and the activity overhead, is impressive enough to stop non-birders mid-snorkel.
Heron Island has a bird colony as significant as its turtle and reef credentials. Black noddy terns nest in the pisonia trees in their thousands, and the dawn and dusk movements of the colony — birds arriving and departing, calling constantly — are as much a defining experience of the island as anything in the water. Wedge-tailed shearwaters burrow under the pisonia roots and can be heard calling from underground throughout the night.
Raine Island — inaccessible to visitors but worth mentioning for completeness — supports a vast frigatebird colony alongside its turtle nesting.
Migratory Shorebirds
The East Asian–Australasian Flyway brings hundreds of thousands of migratory shorebirds to Queensland’s coastal mudflats and estuaries between September and April. These birds — bar-tailed godwits, great knots, red knots, curlew sandpipers, and many others — breed in the Arctic and subarctic of Siberia and Alaska, then migrate south in a journey that represents one of the most extraordinary feats of sustained long-distance navigation in the natural world.
The bar-tailed godwit makes the southbound journey in a single non-stop flight of approximately 11,000 kilometres — the longest non-stop flight of any bird. It arrives in Queensland lean and exhausted, and spends several months feeding on the tidal invertebrates of the coastal mudflats before beginning the return journey north.
Cairns Esplanade mudflats are one of the most accessible shorebird viewing sites in Australia. At low tide, the mudflats visible from the Esplanade walking path hold concentrations of shorebirds — sometimes in the thousands — that are identifiable with binoculars from the path. No vehicle, no special access, no tide calculation required beyond checking what low tide produces. It is, for a single site in an accessible urban location, one of the finest shorebird watching opportunities in the country.
Roebuck Bay, Broome, is the premier shorebird site in Western Australia and one of the most important in Australia. The extreme tidal range concentrates shorebirds at the roost sites in enormous numbers at high tide — tens of thousands of birds packed on small exposed areas of beach or rock as the tide covers the feeding mudflats. Organised dawn roost watches, run by the Broome Bird Observatory, are among the finest structured birding experiences in Australia.
Practical Notes for Reef Travellers Adding Birding
The kit required for casual bird watching is minimal: a pair of 8×42 or 10×42 binoculars and a field guide to Australian birds. The Pizzey & Knight field guide remains the standard reference for Australian species. The Merlin app (Cornell Lab of Ornithology) has Australian bird calls and can identify birds from sound recordings made in the field — an invaluable tool in the rainforest where most birds are heard before they’re seen.
The most productive birding hours are the two hours after dawn and the hour before sunset. Midday, in the tropics, is when birds are least active and least visible. Planning reef activities for midday and birding for dawn and dusk produces an itinerary that makes full use of both opportunities.
A reef trip to Cairns, Port Douglas, or the Atherton Tablelands that includes a dawn walk in the tablelands rainforest, a morning at the Cairns Esplanade mudflats, and a visit to a coral cay with a seabird colony has added a dimension that transforms the experience from a reef trip into something considerably more complete.
The birds were there before the reef tourism. They’ll be there after every boat has gone home. They don’t need you to have planned for them — they’ll appear regardless. But planning for them produces encounters that change what you notice for the rest of the trip.
