Bird Banding at the Weddin Mountains

Last weekend I was out catching birds at the Weddin mtns on a trip run by Harvey Perkins and Richard Allen. The bush was looking very green and lush, greatly changed from the dry and shrinking habitat I last saw there a year ago.

We caught 173 birds of a good variety of species, even though most of the summer migrants had left. We saw a flock of about sixty bee-eaters fly overhead, going north so that might have been them gone too. The birds we caught were of the resident or locally migratory species and there were many juvenile and first year birds indicating that there had been a good breeding season.

 An adult female Crested Shrike-tit, she has a green bib and collar, while the male has a black one - we caught her mate (but he was released before I could photograph him) and he was banded seven years ago at the same site.

A Varied Sittella, wonderful little birds which forage up and down tree bark in extended family cooperative groups. This bird is a full-grown male, the female has a white chin and lower face.

 
Two Spotted Pardalotes: an adult female on the left a male on the right. he is moulting the first four white spots on his crown, from the yellow spots he had while in juvenile plumage, similar to that of the female. His full adult plumage will have all-white spots on the crown and a brighter white stripe above the eye.          

A juvenile Painted Button-quail, fully feathered but only half adult size. These birds have been abundant throughout the grassy woodlands in our area this year and seem to have bred well.

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.

Banding birds at Moruya

Last weekend I was helping Anthony Overs catch and band birds in the escarpment forest at Moruya. Michael and Sarah Guppy are working on a long-term project studying the local birds' breeding behaviour, so several banders went down to catch as many as possible and band them with individual combinations of colour bands. Michael, Sarah and Anthony have been doing this for several years and by marking the birds this way they can determine which bird is paired with which, where they nest and how many chicks they rear. The Yellow-faced Honeyeater above is the most abundant honeyeater in the forest, and there were many birds with flying young.

The adult male Scarlet Honeyeater below, the only one we saw, was probably passing through the area with flocks of other birds post breeding. There were also many adult and juvenile New Holland Honeyeaters.

The adult male Spotted Pardalote below, is another common bird in the forests. They are unusual in foraging in the canopy, perhaps a hundred feet up, but nest in self-dug burrows in a broken bank of exposed soil.


We caught several larger birds too, including Noisy Friarbirds, a Satin Bowerbird, a Crimson Rosella, a King Parrot and the adult Black-faced Cuckoo-shrike below.

The last bird we caught on the Saturday evening was an adult female White-headed Pigeon which was lured down to seed.

Bird banding at Moruya

Last weekend several of us from Canberra went down to Moruya to catch and band birds in a patch of forest. This was to individually mark birds with colour bands so that Michael and Sarah Guppy can follow the breeding biology and habitat use by a range of passerines. The bird above is a Red-browed Finch.

Micheal and Sarah have been studying these birds for several years, and it is all done on their own land so access is easy and the whole project is very well organised. We quickly set up a base station in the forest and started catching birds.

One of the more abundant and studied species is the Superb Fairy-wren, a male is shown here being delicately measured.

Another study species is the Brown Thornbill - the bird shown here clearly shows how readily the birds can be individually identified by the unique combination of colour rings which each bird is given.



















We caught 146 birds altogether of numerous species, and we had two Olive-backed Orioles in one net. The sexes are very similar, but can be distinguished. The male, here on the left, has slightly more green about his throat as can be seen in these photos.

This spectacular bird with a bald head and splendid Elizabethan ruff is a Noisy Friarbird. They mostly forage high in the canopy so it was unusual to catch one. Although these features are readily seen in the field, when in the hand they can be studied more closely. Why do they have a bald head? They are members of the honeyeater family, so this could perhaps help keep their plumage clean of sticky nectar? And look how they have retained eyebrows - a sensible adaptation to keep the rain out of their eyes? What is the purpose of that horn on top of the bill? And when did you last see a birds ears so clearly? Great birds.

Bird-banding at Charcoal Tank, West Wyalong


Last weekend I was out at Charcoal Tank reserve mist-netting birds with a few other people in a group organised by Mark Clayton. Spring has arrived, there was water lying all around and running down the creek lines, the grass was tall and green and the birds were breeding. The birds above were a group of brown-headed honeyeaters, two adults and a juvenile, recently fledged.



There were also a few painted button-quail about, another sign of fresh growth and spring bird movements. This was a female which we caught.



We caught twenty-two different species. mostly locally breeding birds which were on their breeding territories. These are two spiny-cheeked honeyeaters, an adult on the left and an immature on the right.


The adult spiny-cheeked honeyeaters have white cheeks and the spiny plumes are obvious.



The immature spiny-cheeked honeyeater has yellow cheeks and its spiny plumes are less developed.


There was a pallid cuckoo calling all weekend but we never saw or caught it. We did however catch a fan-tailed cuckoo which we never heard calling.


This bird was surely a sign that bird were breeding well now that the drought has ended. I found further evidence in the form of red-capped robins with young in the nest and another pair with fledged young, a pair of jackie winters with eggs and inland thornbills with young in the nest.


The cuckoo really was a splendid bird and when it opened its bill it showed its typical cuckoo bright red gape.
