Following the recent split of Western from Thick-billed Grasswren, the June 2012 Southern Birding Services Grasswren tour included this species for the first time. The tour took 8 participants in two 4WD vehicles up the Birdsville track. The tour was guided by Peter Waanders, assisted by Helga Kieskamp. A total of 148 species were seen (very few waterbirds), including all Grasswrens (though fog prevented good views of Short-tailed). It was a cold, overcast morning and the birds took some time to become active but after a while we were looking at a Southern Scrubrobin singing from a bare branch. Its partner was foraging on the ground below. A very inquisitive family of Emu amused us and a Chestnut Quail-thrush was heard singing, and located with some effort, after which great views of a pair were had by all. Other birds present included White-fronted Honeyeater, Gilbert’s Whistler, Mulga Parrot, Spotted and Striated Pardalote, 7 species of Honeyeater, White-browed and Chestnut-crowned babblers, Restless Flycatcher, Red-capped and Hooded Robins. After a successful first stop we set off in search of our first Grasswren species: Striated. These ground-dwelling birds inhabit large patches of the spiky spinifex grass. At the first site we tried one was heard briefly, but disappeared without a trace. To make up for that we had great views of Shy Heathwren, proving not shy at all. We checked another large patch of spinifex where we soon heard, then saw, a Striated Grasswren.
