#53 Rain in the Hunter Valley

During the past 5 days I've tipped 165mm from my rain guage; some areas of the Hunter Valley have received more, especially the coast. According to the local TV station, Singleton's January average is 44mm - one-point-something-mm was measured this January, so this rain is a blessing.

The Hunter River in front of my home (16 Feb 09). The row of juvenile Casuarinas in the far centre of the image represents the eastern (near) bank, making the minor flooding apparent (peak at Singleton 15 Feb 09 was 2.45metres).


My stressed gardens have had a good drink, my crunchy yellow lawn is saturated and greening up, and my tanks are over-flowing! But that's not all - my backyard wildlife is singing with glee and literally jumping in the rain.

Frogs! Where do they all come from when the water begins to pool? I slopped around the backyard last night listening to the inarticulate chuckling ruckus exploding from the puddles hidden by darkness. I found it difficult to separate the different calls, but I think there were four species calling.

The puddles are in the grazing paddock adjoining our yard; the paddock is not ours, but I have access to it and will be looking forward to checking out the tadpoles. I can already see white frothy rafts, the results of frantic mating throughout the night. There's no mucking around with preliminaries in the spirited game of frog jumping; time is of the essence - once he's got his girl, it's grapple, mount, she lays eggs and he fertilises externally. Job done!

Puddles (frog nurseries) beyond my backyard


Naturally, I've been searching for frogs in my backyard. Ornate Burrowing Frogs, Opisthodon ornatus (formerly Limnodynastes ornatus) have been visiting my back porch, probably to hunt for insects. These colourful, fat, glum-looking frogs are an absolute delight to observe, even if they are rather inactive.

How could you not love this round little frog - mind you, he does look rather bored with my company, so perhaps the admiration is not mutual.


All manner of invertebrates have been flushed from their earthen homes by the excessive rain. A homeless Garden Wolf Spider (Lycosa godeffroyi), expectant mum and superior being of my backyard spider kingdom was also ahunting on my patio last night.

I'm rather fond of these hairy giants, but scared stiff at the same time. I wanted an up close and personal photo, but not just any old close-up - I wanted a view under that impressive torso held aloft by those lanky segmented legs.

I was well aware those legs were made for speed, and I have seen these beasties performing high jumps, so I had to focus on the end product to gather the courage to get down to eye-level with Mrs Wolfie with her precious egg sac in tow. Trouble was, to get the best angle, I had to back myself into a corner and get down on my belly - I broke all my rules and left myself without an escape route. . . . .

. . . . . but I got my picture!

Later, I was thrilled to witness a successful hunt as Mrs Wolfie ambushed a plump 1cm beetle. I shuddered as I heard the crunch . . . crack of her fangs grasping and piercing the beetle's crusty exoskeleton. It's a tough and violent world down there amongst the dirt and grass - or in this case, on my back step!

Brilliant photo!

hello Cheryl,

Thank you very much, and welcome to my blog. I am hoping this Wolf spider will keep visiting my back porch so that I can eventually see her piggy-backing her spiderlings - this is an amazing sight, and as yet I haven't been able to get a decent photograph of the spectacle that is rare in the spider world.

Cheers
Gaye

Hi Gaye
I am aware that the rain we have had in Robbo is just the tail-end of what you have received, and a fraction of the north Qld rains. .
.
We have suffered in the unexpected heat. our plants are not adapted to heat like that, so it really shows up.
.
Great shots. Your Burrowing Frog looks quite big and fat. Is that right? I have never seen one, although they are reported around here.
.
You can relax with the Wolf Spider. Yes, she can be quick, but just to escape from your attentions. They have fantastic vision, and know exactly what you are up to, whereas the slow old Funnelwebs and Trapdoors are virtually blind and stumble around.
Interesting comment on the sound of the attack on the beetle. I have seen reports of people hearing the same sound from Funnelwebs attacking other small creatures. Very interesting observation.
Cheers
Denis

hi Denis,

thank you for your detailed and interesting comment. Heavy rain is forecast for tonight and tomorrow in the Hunter. As you are aware, this rain has also followed an extended period of extreme heat in the Hunter - strange weather indeed, which is likely to become the norm.

The Ornate Burrowing Frog was about 5cm long, which is their maximum size. It was, however, fatter than those I have seen previously. If it had sheltered in the crack between the concrete floor and brick wall where it is hiding its hind quarters in my picture, I fear he might get stuck.

The capturing and crunching into the beetle by the wolf spider was a fascinating observation, indeed. Not the sort of act to watch just before bed, as I did.

You will know the scope of brilliant nature observations that are literally right out the back door, too, Denis. There is always something of interest to be found even if the heavens have opened up and outdoor activities are impractle. But I am looking forward to some fine weather to go exploring again.

Cheers
Gaye

G'day Gaye,
A delightful entry. Beautiful descriptions of the frog sounds and their breeding.
We hope to get some moisture from your system way down here soon. They reckon if that low off the coast up there slips down a bit, we might be rewarded. It would be wonderful.
A very enjoyable read - thanks,
Gouldiae

hi Gouldiae,

thank you so much. I do hope the rain gets down to your area.

Cheers

Hi Gaye
Do you have the chance to do an update?
It seems a lot more rain has fallen on the north coast.
Not sure if it landed in the Upper Hunter Catchment, or not.

hi Denis,

as far as I am aware, Singleton, Muswellbrook, Scone and Murrurundi (mid to upper Hunter) have each received about 30mm over Mon, Tues, Wed combined (although I have only received 4mm just outside of Singleton).

There is still minor flooding of the Williams and Paterson Rivers, but the Hunter has receded. On Sunday the Paterson had burst its banks at Tocal.

The Hunter Valley has not received anywhere near the rain that the North Coast has received. Up to 10mm is forecast for tomorrow for the mid Hunter.

Regards
Gaye
