There is a bush block on Hervey’s Range which I visit regularly and often write about because its wildlife, large and small, continues to surprise me. (This link will take you to posts about previous visits.)
Last weekend’s special treat was a bottlebrush tree in full bloom, surrounded by enough honeyeaters to fill an aviary; all I had to do was stand nearby and point the camera at them Continue reading “So many honeyeaters!”
I’m still finding creatures I can’t identify and having to call on my Friendly Local Experts for help. They are very generous with their time, and I thank them for their help but I don’t want to embarrass them by getting anything wrong so they will remain Anonymous FLE’s (unless, of course, they read this and choose to be named). My latest call for help related to these little birds:
They were attracted to the sprinkler at the bush block on Hervey’s Range I visit regularly. My first thought was that they were Lemon-bellied Flycatchers (aka Fly-robins) but I couldn’t account for the white streak under the eye in the second photo. They looked a bit too small, too, so I asked.
The reply was prompt: “… southern race of Fairy Gerygones: the first one is a female, the second with the white streaks is a male.”
They were new to me so I looked them up. Slaters’ Field Guide calls Gerygones “Australian Warblers” and their “Fairy Warbler, Gerygone palpebrosa,” is “10 – 11.5cm” – Sunbird size, not Brown Honeyeater size. Birdway, which is regularly updated with name changes in a way that books can’t be, includes them in “Australasian Thornbills, Scrubwrens, Gerygones & Allies (Acanthizidae).” The Fly-robin, for comparison, is here.
One of the area’s most common honeyeaters, the Lewin’s (Meliphaga lewinii), also came to enjoy the sprinkler:
As usual, I came home with a collection of spider and insect photos. The most interesting are now on flickr, here and close to it, in my photostream.
Australia has just over twenty species of goanna (aka monitor lizard) but if anyone talks about seeing ‘a goanna’ they usually mean the largest local species. In our case, that’s the Lace Monitor, Varanus varius, which happens to be the second-largest in the country. (The Perentie of the central deserts is a little larger, growing to 2.4m as against the Lace Monitor’s 2.1m.)
The normal colour scheme of our Lace Monitors (I’m simply going to call them ‘goannas’ from here on) is dull grey-black with a generous spattering of creamy spots, as in my photographs of goannas at Wallaman Falls, on Whitehaven Beach and in the hills above Mission Beach (scroll down each page for the pics).
When we saw this reptile crossing the back yard of a weekender on Hervey’s Range we were surprised enough to check the reference books. It was close to two metres from nose to tail, so there weren’t many possibilities.
This strongly-banded sand-and-charcoal goanna is, in fact, still Varanus varius, although the ‘Lace’ name doesn’t suit it very well at all. It is known as ‘Bell’s form’ or ‘Bell’s phase’ and is more common in the drier inland than on the coast.
The Hervey’s Range property is just on the inland side of the crest of the range, although with a higher rainfall than regions further West, so a Bell’s form goanna is not too far out of its normal territory. That said, Wikipedia has one from the Fraser Coast (Hervey Bay – Maryborough) in its Lace Monitor gallery, so the geographical separation can’t be too strict.
Regular readers will know that I visit a bush block on Hervey’s Range, half an hour or so inland from Townsville, fairly often. It’s a great place for spiders, though I’m not quite sure why; earlier visits have brought me the two species of golden orb weavers living side by side which I mentioned here, my only whip spider, my only tarantula and many more. My latest visit brought me these three little ones.
The Horned Triangular Spider, Arkys cornutus, is so attractively bizarre that it is photographed more often than it otherwise would be. This is the first I’ve seen in real life and yes, I photographed it too.
It lurks in foliage waiting for unwary prey to land close enough to be caught between its impressively barbed front legs, so its hunting strategy is the same as the crab (aka flower) and lynx spiders. However, it is not closely related to either of those families but is an orb-weaver (Araneidae, Araneinae) which for some reason has given up weaving.
My next odd little beast is one of those crab spiders (Thomisidae), the Hairy Crab Spider, Sidymella hirsuta. It’s about 15mm long from toe to toe but its body is almost the same size as that of my Arkys.
My third spider isn’t as photogenic as the other two but I thought I should include it because I saw it in the same patch of bushland on the same morning.
It’s a Cyclosa, a member of a genus of smallish orb-weavers with the habit of constructing a messy strand of debris and (sometimes) egg sacs across the middle of their web and pretending to be part of the rubbish. It must be an effective strategy because they are quite common.
Naming the genus is not problematic but even the experts avoid more exact identification, saying things like, “Cyclosa is very diverse in Australia with at least 10 species, currently under revision. At this stage it is not possible to reliably identify Australian Cyclosa to species, with the exception of a few,” and I’m not going to rush in where they fear to tread.
The thread I photographed contains (counting from the top) debris which looks like tiny dead leaves, four pale egg sacs, dark debris, the spider, more dark debris, a bigger pale bundle and a loose bundle of rubbish; the whole thing is only about as thick as a grass stem. Click on the images, as usual, for more detail.
We regularly visit a “bush block” on Hervey’s Range, 40 minutes’ drive inland from Townsville. Six weeks ago we saw lots of Rainbow Lorikeets feeding on the bright red blossoms of the Umbrella Trees (Schefflera actinophylla) there, but when we returned a couple of days ago the flowers had become fruit and the lorikeets had shifted to a tall gum tree, 50 metres away, which had burst into blossom in the meantime.
A family of Figbirds (Sphecotheres vieilloti) had taken their place on the Umbrella Tree, feeding gregariously on the dark brown fruit. There was certainly plenty of it it to share!
The Umbrella Tree is native to this part of the world and is not a problem here: it grows well but “has maintained a balance with other native species,” as this DAF page says. The page goes on to add, however, that “when it is grown in southern Queensland, this fast-growing invader out-competes local native species,” and this other Queensland government fact sheet simply calls it a weed (but has better pictures of it).
That’s unfair, since a weed is, when you come down to it, simply a plant where you don’t want it. Even Lantana, loathed up here, is not a weed everywhere.
