Magazine article

A copy of the Leopard magazine arrived with the post today from Scotland. And there on the cover was one of  my photographs of a ptarmigan taken last summer while I was over there. There is a full four page article inside, which I wrote for the magazine with more of my shots illustrating the ptarmigan's life in the Scottish Highlands. Go to http://www.leopardmag.co.uk/ for more info. One of the inside photographs and caption is copied below.

Bird banding in Mallee

Last weekend I was out banding birds in mallee woodland at Charcoal Tank Nature Reserve, near West Wyalong. The trip was organised by Mark Clayton who has been banding birds there for over twenty years and seen big changes in bird numbers there as the habitat has changed over the dry years and now a wet one. One bird we caught was a fine adult male Common Bronzewing, above. This is a common and widespread Australian species of pigeon, readily identified by the male's pale forehead and rich rusty red underwing.  

We caught three Painted Button-Quail which have bred well in the tall grasses that have grown throughout the east in the high rainfall of the 2010-2011 spring. This bird is the more brightly coloured female with chestnut neck, back and coverts. The male which incubates and rears the chicks is smaller and more buff in colour.

The grasses are about a metre tall, and have cast their seeds, but still provide a thick understory to the red ironbark trees. In previous years the ground has been open, with a thin covering of leaf litter and sparse grasses and shrubs.

We also caught a mallee heath specialist species, the Shy Heathwren. This is closely related to the Chestnut-rumped Heathwren, which it clearly resembles. That species is however, more associated with coastal heaths and scrub farther east. The Shy Heathwren fills this habitat niche from near West Wyalong and to the west.

The bird we caught was an adult female, identified by the pale eyestripe and dull wing flash of white and dark feathers. The male has more a pronounced white eyestripe and wing flashes.

While we were catching birds in nets, we ourselves were repeatedly caught in the large anchor strands of cobwebs spun by orb-weaving spiders. Here a female sit in the centre of her web while the smaller male sits quietly on the edge. She is quite likely to eat him after they have mated.

Juvenile tawny frogmouth

Most of the tawny frogmouth chicks have fledged now and are roosting with the adults during the day. Here an adult male is next to a pine tree trunk with a large juvenile next to him. The young bird can be readily identified by the shorter bristles above its bill. The young bird's tail and wing feathers are also not fully grown yet although it has been out of the nest for over a month. Note the rounded end to the its tail compared with the sharp tip to the adult's tail feathers. Also, there are yet shorter feathers on the underside of the tail.

Seen from the top side, the young bird is noticeably more buff in colour generally, with less intricate dark markings on the coverts than on the adult. Also the difference in the roundness of the tail feathers is very clear. The edges of the wing feathers - the primaries and secondaries are all clean and smooth, unlike the adults' ones which are rough and jagged through wear and tear.

Owlet nightjar

The weather is warming up now with a predicted high of 35 degrees tomorrow. The cicadas are singing loudly, very loudly, and most of the birds have fledged their young. Two late frogmouth nesting attempts have failed. I suspect the eggs were infertile as the birds had been sitting on them for longer than the usual incubation period with no sign of chicks hatching. There are chicks in two other nests and one pair are sitting on their third clutch of eggs having failed to rear chicks from two earlier attempts.

While checking one of these nests, I walked past a tree where Anthony had owlet nightjars last month. And there was a bird sitting at the entrance to one of the holes. It ducked back a little more into the hole as I approached, but stayed there looking out. These birds favour trees with multiple holes or with other suitable holes in trees within fifty or a hundred metres. If flushed by a predator they dart from one to another, with a confidence that says they know exactly where they are going.

I left this bird at peace and wondered at its plumage and posture. The big black eyes look so like knot holes in the tree and the stripes on its head blend well with the crack lines. Perfect camouflage. Or have they adapted a plumage pattern similar to that of sugar gliders which are common in the same habitat, and so gain benefit of less predation. The central stripe over the head, round face and large eyes all fit. Perhaps potential predators are less likely to attack a glider, e.g. a sparrowhawk which only take birds.

Sparrowhawks

Yesterday it was goshawks, today a female collared sparrowhawk came into the garden, caught a house sparrow and promptly ate it. A few days ago a male sparrowhawk was hunting the sparrows in the garden, chasing them into the dense canopy of the trees. We were playing cricket at the time only a few metres below them.

Sparrowhawks are regular visitors to the garden and they probably nest in someonelse's garden nearby. The goshawks are mostly in the woods. Both species are feeding large young now so there will be a heavy demand for them to provide food. As we have free range chickens in the garden sparrows come in to feed on the chicken food. It is usually the male sparrowhawk which catches the sparrows and smaller birds such as young starlings. The larger female usually catches Indian mynas, crested pigeons and rosellas - crimson and eastern.
