Grasswren Grand Slam in Record Time

Birding, TourismChris Watson

There’s a well-known saying among birders, particularly among those who live near the coast: seabirders are real birders. Anyone who has spent a day on the blue paddock trying to compare the bill dimensions of prions while dodging the sluicing chunder from birders of more delicate constitution as the floor rolls under your feet and the salt spray mists your binocular lenses will understand that it’s a claim not without some justification.

In Australia though, it’s arguable that there is one other type of extreme birding that may lay claim to also being the domain of “real” birders: grasswrenning. That’s a word now.

I’ve heard it said that any old duffer can notch up a list of a few hundred species in Australia if they simply do some pretty basic birding and visit a handful of different regions. International birding tours sometimes rack up Australian bird lists of 400 or even 500 species in just a few weeks of busy birding and a few internal flights. But a good measure of an Australian bird list, and of the true birding grit of the list-owner, is the number of grasswrens on the list.

The grasswrens in the genus Amytornis are a group of birds which are fascinating and frustrating in equal measure. They’re among those bird species which can look drab or boring in a field guide but which routinely knock your socks off in the field when they are up close. If you’re lucky enough to get a prolonged look at any species of grasswren in the open, their plumage reveals all sorts of subtleties that you won’t have anticipated.

There are anywhere between 10 and 14 species recognised, depending which taxonomy you follow. None of them live in particularly accessible places and most live in decidedly remote and difficult terrain. Most of them favour the shin-ruining spinifex grasses; a group of plants with the distinction of being both figuratively and literally, a complete prick. The ones that don’t live in spinifex, live in clumps of similarly dense and unfriendly vegetation. They range from some of the hottest and driest deserts to the humid and monsoonal tropics. They’re mostly furtive, shy, and able to disappear from view in their chosen habitat leaving a birder feeling completely gormless in the infuriating knowledge that the birds are all around, at close range, but completely hidden from view and unlikely to reveal themselves.

A few species favour rocky slopes with either loose scree underfoot or large boulders that only a rock wallaby, and the grasswrens themselves, can safely negotiate. Some are endangered and disappearing from their already restricted ranges as a result of fire, feral cats, land clearing, or combinations of all three.

Grasswren habitat: harsh, beautiful and remote. Cane grass on dunes of the Simpson Desert is home to the Eyrean Grasswren A. goyderi.

So in summary: they’re small, rare, fast, furtive, superbly cryptic, hard to get to, hard to find, and hard to see if you do find them. And this is their charm. They’re a real birder’s bird.

Well-known South Australian ornithologist and tour leader Peter Waanders recently hatched a plan with two of my Northern Territory off-siders. It was a plan that was nothing if not ambitious and, frankly, had some questioning Peter’s sanity – to see all species of grasswren in a single tour. It’s audacious. If ever a leader was going to be able to pull-off such a feat of birding brilliance, Peter’s name would be near the top of the list. His guiding outfit, Bellbird Tours, is already best-known for running the regular 6- and 9-grasswren tours which plough through the dry interior of the country each year and only rarely miss any of their targets. His dry country tours also have an enviable strike rate with other highly-sought desert delicacies like Grey Falcon and Letter-winged Kite.

To cut a very long story short – they did it.

In an achievement which must be a historic first for Australian birding, Bellbird’s Great Grasswren Air Safari saw all 11 of the currently (widely-accepted) species of grasswren in just 14 days [and I think they may have seen one of the proposed splits as well which would take their total to 12 species by Clements taxonomy]. In fact, the news of their final tick, White-throated Grasswren Amytornis woodwardi, came through the day before the tour ended so they actually saw every grasswren species in 13 days.

For anyone familiar with traveling in outback Australia, you’ll understand what an extraordinary achievement this is. By car, aircraft (both fixed-wing and helicopter), and finally on foot, the intrepid band crossed the entire continent. With crucial assistance from Red Centre expert Mark Carter and Top End bird-finder and River God, Mick Jerram, they nailed the tricky central and northern species.

In under a fortnight, they found and saw an entire endemic genus; a genus of our most infamously challenging birds. I’d be surprised if there is anyone else who has ever completed this coveted full house in less than a month. Well done one and all and congratulations Peter, Mark and Mick – only other tour leaders will ever understand how nerve-wracking a tour like this can be.

A Short Digression

Amid all the back-slapping and the celebratory Darwin stubbies though, there’s another consideration. An important aspect of an initiative like this is that it demonstrates the productive symbiosis that can exist between research and tourism. This is a partnership which is well-established in numerous locations internationally but has yet to be widely-explored in Australia.

Some grasswren species are infrequently recorded and their distributions are imperfectly known. Many of the species which are seen each year are recorded at the same sites; well-known sites where public access is granted and the birds are known to be present. Tours like this don’t just provide an opportunity for birders to get difficult species on their lists. They also provide the means for experts (and all of the leaders on this tour are certainly that), to visit different areas, both during the tour and on reconnaissance visits during preparation. During these visits, birds are sometimes found at new sites. Breeding activity is sometimes noted. Previously occupied sites might be discovered to have been abandoned or habitat destroyed. Non-target species are also noted and atlas surveys are completed. All of this is crucial observational data which is coming from country rarely accessed by researchers from professional research organisations because visiting is prohibitively expensive.

Research and data collection of this nature being funded, directly or indirectly, by tourism is something we really ought to discuss more often and support wholeheartedly.

 

Well done again to all involved and particular congratulations to Peter, Mark, Mick and the team at Bellbird Tours for pulling off the grip of the year.
