Ian’s Bird of the Week ~ Pilotbird ~ by Ian Montgomery
Newsletter ~ 3/31/15
The primary targets in East Gippsland were the Sooty and Masked Owls, but there were several daytime birds on the wanted list too. One of these was the Pilotbird, a smallish – 17cm/7in long – brown, ground-dwelling bird of the mountain ranges and dense coastal scrub of southeastern Australia from just south of Sydney almost to Melbourne. I’d seen one only once before, near Mittagong in New South Wales 16 years ago, but that encounter was only a glimpse and no photography was involved.
It’s an unobtrusive bird and easy to overlook, unless you know its flutey, far-carrying call, sometimes rendered as ‘guinea-a-week’. My Victorian friends knew a good spot for it in coastal scrub and we found one there with relative ease, returning the following day (first photo) to get better photos. It rummages around in thick undergrowth looking for invertebrates. The second photo has a red dot showing the exactly location, beyond the sinuous brown branch, so you can appreciate that we are lucky to be able to see anything much of it in the photo. It has unusual buff dark-edged feathers on the breast, giving it a scaly appearance. The plumage is apparently dense and silky as reflected in its scientific name: Pycnoptilus means thick-feathered, and floccosus is derived from the Latin floccus and means ‘full of flocks of wool’, which, I must admit, left me not much the wiser.

It’s common name Pilotbird arises from the bird frequently associating with Superb Lyrebirds, taking advantage of the digging habits of the latter (third photo) to snatch up revealed invertebrates. Some sources say the name Pilotbird comes from the similar habit of Pilotfish which associates with large marine predators such as sharks; other say that the Pilotbird by its call led early settlers looking for food to lyrebirds. I prefer the first explanation. Lyrebirds are very vocal in their own right and don’t need another species to advertise their presence. Lyrebirds are perhaps the world best mimics and are known to mimic Pilotbirds, and it would be easy to imagine that this attracted Pilotbirds in the first place and they then learned that this was an easy way to get dinner. We did in fact see several Superb Lyrebirds dashing across the roads of the forests where the owls lived, though the coastal scrub didn’t strike me as good lyrebird habitat.
This photo of the lyrebird digging vigorously reminded me both of Scrub-turkeys and Chowchillas (fourth photo) and I wondered whether the Pilotbird had a behavioural counterpart in the forests of Northeastern Queensland. The Pilotbird is usually placed in the Acanthizidae, the family of thornbills and their allies (though it shows some affinities with the bristlebirds Dasyornithidae), so I checked up on the Fernwren (fifth photo) another brown, rummaging Acanthizid endemic to the Wet Tropics.
Sure enough, HBW (Handbook of Birds of the World) reports that the Fernwren “sometimes associates with Orange-footed Scrubfowl (Megapodius reinwardt) and Chowchilla (Orthonyx spaldingii), following in close proximity and catching prey disturbed by their feeding actions”. The Orange-footed Scrubfowl is, of course, a cousin of the Brush-turkey.
So maybe this week’s bird of the week should be entitled ‘small brown rummaging birds of the forest floors of eastern Australia’.
Greetings
Ian

Lee’s Addition:
For you are my rock and my fortress; and for your name’s sake you lead me and guide me; (Psalms 31:3 ESV)
Teach me to do Your will; for You are my God; Your Spirit is good; lead me into the land of uprightness. (Psalms 143:10 MKJV)
What great protection colorations these birds have received from their Creator. I am sure when the birds of prey are in the area, rummaging types of birds are very thankful for their less colorful outfits.

Thanks for the photos, Ian. And thanks for hosting this series, Lee. (And thanks for making all of these fine-feathered wonders, God.) The Superb Lyrebird has an overall shape that reminds me of our Roadrunner, 2 of which were so close to the road yesterday that I stopped my car to make sure that they got safety into the front yard of a neighbor. Of course, the Superb Lyrebirds has a dignified, noble, almost regal appearance (and that tail has an exquisite detail that reminds me of peafowl), — whereas the Roadrunners look a lot rougher, scrappier, as if they were on-the-job cowboys darting here and there, in the bush country, to keep a cattle-drive together. (“Yee-haw!” — I mean, “Meep, meep!”)

Can sure tell you live in Texas. Thanks for the observation. Maybe we will see one of your “texas lyrebird” when we pass through Texas later.

In East Texas you might confuse the locals if you refer to “lyrebird” — due to the local accent someone might think you are referring to a lawyer named Byrd. (Why would an East Texas accent make the word “lawyer” sound like “liar”? Hmmmm.)
