What's wrong with rolling out the weedkiller?

Weeds are bad! Right? Gotta get rid of them! Right?

Round-up bad, weeds worse! Right?

So let's get the Hi-lux super spray unit out and zap all that hymenachne and pink burr and stuff out of the swamp ricegrass at Tyto. Right?

Wrong! Wrong! Wrong!

See what happens! Weeds say thanks very much and spring up all along the vehicle tracks through the ricegrass. Notice how high the dead grass is. Weeds can't get through from down below. Until the nice spray men come along and flatten the way for them.

Hymenachne and wild tobacco both benefit. So the work to kill hymenachne is now promoting its growth.

And you'll never guess what efforts to remove salvinia and pink lotus from the main lagoon system have achieved. Temporary and ugly death of lotus and the sinking of free-floating salvinia.

Plenty more of both sitting in the mud below (lotus) and at lagoon edge (salvinia). Waiting for the next rains (January, probably, if El Nino allows).

Could be worse. Well, yes and it certainly …

Hungry youngsters might call till blue in the face

Young Blue-faced Honeyeaters (Entomyzon cyanotis) left nest little prematurely in the caravan park lately. One needed rescuing from danger of drowning in swimming pool. It overnighted in a nice warm and dark carton before being placed outside next day in an open clear plastic container. Parents resumed feeding it and youngster scrambled  up into trees over next few hours.

Brother or sister didn't ever hit the ground, though often coming close. Blue-faces are among the most raucous honeyeaters (and aggressive: will swoop people sometimes even when not nesting). Noise starts early in life and both young birds could be heard begging for days through much of the park. And are still going strong. Wondering about the 'line' above the bird? It's simply a fine portion split from a palm frond.

Honeyeater doesn't give a fig for fruit trend

Looks like Macleay's Honeyeater (Xanthotis macleayanus) lost way and ended up in drying wetland habitat, but bird grabbed prey from planting in the Jourama Falls camping area yesterday. Seldom seen so many honeyeaters active in the area. Most were feeding on newly ripened cluster figs. Much interest also shown in boiled red capsicum cast away by departed campers. Doesn't take lot of imagination to see links between extreme dryness generally being experienced this year and a strong preference among birds for moist feed.

With preferred feeding growth not doing so well, Mistletoebird (Dicaeum hirundinaceum) takes to bottlebrush flowers  hanging over parking spots at Tyto Wetlands entry. Air has been full of their sharp high calls lately. Conditions would seem against much breeding as materials for their soft woven 'baby bootee' nests have dried up.

Dry? I'll say, says Brown Honeyeater (Lichmera indistincta). More than bone dry. This is shell dry with freshwater musse…

Giant Grey Huntsman flashes tiny eyes

So much hanging around trees lately probably makes others suspect I've developed a fussy-dog toilet fetish but today turned up a Giant Grey Huntsman (Holconia immanis) that wasn't peed off when its bark hide was turned inside out.

Interesting sidelight to photographing the placid spider was counting the number of flashes reflecting from all those tiny eyes. Best of all, no angry hairy 'monster' threatening to bite me.

No bite threat, no hair, fewer eyes: Gumtree Shield Beetle (Theseus modestus) stands out as attractive bark dweller. Six legs good, eight legs trickier.

And then there's no legs at all. Couldn't get Red-bellied Black to stop for head-on shot so had to settle for harsh crop of snake speeding across gate shadows.

Stubble Quail stumbled upon

Stumbled upon Stubble Quail (Coturnix pectoralis) in drying grasses at Mungalla Station today, some distance from usual haunts near creek track and in weedier mix of flora. No sign of any partner, but luck mainly determines sightings of the species.

Much more easily found, specially this very dry year, Horsfield's Bushlark (Mirafra javanica). The birds seem to be thriving in competition with  the scores of Australian Pipits ever present on tracks and bare spots in the grasses, though the Bushlarks favour slightly greener cover.

Poking and peering at the park's paperbarks

Bit of a poke around big paperbarks at front of the mown and park-manicured Tyto precinct this week turned up some small wildlife unnoticed by the tourists.

First, wee Black House Spider (Badumna insignis), probably closely related to the little bugger so excruciatingly met the other day (previous post). Smaller than my little fingernail and striving to look even smaller after being spilled out from behind bark onto path.

Nearby in wet, rotting tree fork, one of many Mr Bigs, Carpenter Ant (Camponotus spp.) charging out to find the agent responsible for poking around top of presumed tunnels and galleries chomped into the  wood. Bigger than my thumbnail and said to pack a mean bite. Queens (not seen) said to be gigantic (for ants).

A hairy find, caterpillar of Cinnabar Moth (Tyria jacobaeae), an insect introduced to control Tansy Ragwort  (Senecio jacobae).  Hope that's going better than many such introductions. Hinchinbrook shire tried weevil control against Salvinia. Seems task w…

Tiny spider brings Cassowary walker down to Earth

Taken more than six months and about 15 trips but today finally ran into (almost literally - had to brake hard when he popped onto road near front of the Troopy) occasional  Wallaman Falls walking companion, male Southern Cassowary (Casuarius casuarius).

As usual he had little to say and wouldn't look me or the camera in the eye during our 10-minute walk and talk along the road and in and out of roadside forest fringe. Seems hard to believe that no matter where one stands or how close one gets the bird simply walks on, head mostly down (that's where the food is - though there's not much falling anywhere on the ridge road these days) and unconcerned about someone walking within touching distance.

Dangerous walk? Not at all, so long as attention is paid to bird's body language. However, high on the buzz of the meeting after so long without a sighting made I the mistake soon after of picking up a tiny supposed woodlouse or similar from under some peeling bark. Oops. Twin…
