Sugar Glider

A tree came crashing down today

While I was out looking for Tawny Frogmouths today I heard a crash and looked around to see an old tree fall down. I thought it might be interesting to see what animals had been disturbed, or lost their home as I could see that the tree was very old and had some cosy holes for animals to sleep up in.

Sue enough, as I approached, a Sugar Glider  Petaurus breviceps slipped out of a broken branch and scuttled up the nearest standing tree. It wasn't too alarmed by my presence, but did go high up very quickly. For that is their strategy to escape, they can climb well, but they can fly too. And when it reached the highest branches it simply jumped into space and glided onto the next tree about twenty metres away. It landed on the top of another dead tree which it clambered down until it found a hole it could wriggle into. And that was that, a new home, safe from predators.

The Sugar Glider dashes up a tree

Once up high, the glider stopped to watch me. The folds of skin which help it glide can be seen rippled along its flanks.

Meanwhile, take a look back at the first picture. There are a pair of frogmouths up in the tree, in the top left. I noticed the male's tail protruding out from the nest after the glider had disappeared and I could re-focus my attention to my original purpose.

I was out watching the frogmouths last night with Steph and Matt. There were a pair which appeared with fledged chicks last year from an unknown nest site, so we staked out the area at dusk. The female was calling from her daytime roost perch for ten-fifteen minutes as the light faded. Then as it became truly dark she shifted to another perch and continued to call her rapid repeating 'ooom-ooom'. The call is distinctive, but so soft, we wondered how far away her mate was. The call only carried to our ears for about fifty metres. Do they do so to avoid attracting attention from their main night-time predator, the Powerful Owl? Then the male swooped in silently from the shadows and landed right next to her. She twitched her tail, he jumped onto her back and they mated for a minute or so. He then went off and hunted, catching an insect from some foliage up in a tree. She flew over to their nest site and continued to call. 

So, we accomplished our quest to find the nest site and all this happened in about half an hour immediately at the onset of true darkness. There is so much to see in the dark.

Bearded Dragon

Flat out

The days are warming up and the first of the larger reptiles have been out and about. The Shinglebacks Trachydosaurus rugosus are wandering slowly about the bush and others like this Bearded Dragon Pogona barbata are spending much of the days warming themselves up in the sunshine. This one was well camouflaged with its dusty skin matching the open dirt between the grass tussocks. It lay motionless as I stepped past it; its legs hung down along its tail, its skin spread out and the whole body aligned with the sun, all to maximise capture of the radiant heat.

It seemed to be trading off the powers of its concealment against the expenditure of its limited energy, having just warmed up a little and not being very active yet. For it was keeping a steady eye on me in case I did after all pose a threat and it would have to use that little energy to flee.

Tawny Frogmouth laying egg

The female gathers her newly-laid egg

Last night the female of the Tawny Frogmouth pair which I have been recording nest-building, laid her first egg of the year.

The male who had been covering the nest all day, left at 1813 hrs and the nest was left unattended until 1918 hrs when the female arrived with a twig of nesting material. After she found a place for that in the nest, and spent about ten minutes arranging the other material, she settled down in a relaxed position. She was evidently breathing deeply as her head and shoulders were heaving up and down - something they do not usually do when on the nest. So, I assume she was preparing to lay. Then after about twenty minutes, at 1949 hrs she got up and turned around, gathered an egg under her breast and re-settled down to incubate. This she did for about four hours, when her mate arrived with a twig. She left to hunt and he continued to incubate after gently settling over the egg with his breast feathers fluffed up to expose his brood patch. He incubated the egg for an hour and a half, before she returned for a further two hour session. Then they did an hour each, until the male took over a half hour before dawn. After which he was on the nest all day while she roosted in a nearby tree.

Gang Gang Cockatoos

There seemed to be parrots everywhere in the bush yesterday as they were all prospecting, exploring, or defending nest holes. This  hole looks a bit too large for these Gang Gang Cockatoos, although there might have been a tighter cavity down at the bottom, so the male went in for a look-see. These parrots are such quiet and approachable birds and the male's bright red helmet is very smart.

The male seems to have dipped his head into a pot of red paint lying in the hole

The twist of red feathers from the back of his head over the crown is a small but
spectacular piece of plumage. She also has a crest, but it lies tucked away. The female's plumage is just as well evolved as the males, although more for the purpose of concealing her. She has a fine pattern of bush-colouring, which hides her well as they sit quietly in the trees. These birds are easily overlooked, unless one is familiar with their subdued creaky calls, or their habit of dropping crunched-open gum nuts to the ground below.
