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.

Storm

Last weekend there was a terrific storm and lots of trees were blown down. Several trees fell around the previously mentioned nest. I checked the birds anxiously during and after the worst weather and the male was sitting tight throughout. The eggs are due to hatch any day now and it would have a been a great loss if his efforts failed.


The neighbouring birds also sat tight through the storm and here the male sits hunched down as the rain runs over his back and the branches are soaked. Like all the other nests I know of, they survived, many with adjacent trees coming down. By selecting to nest away from the ends of branches, and on thick ones, Tawny Frogmouths seem to avoid the worst effect of the winds.

Early nests

A male frogmouth sits tight on his nest, with unusually little cover above him, on a wild wet and windy day.

It has been quite a wet winter in Canberra this year and in response, several tawny frogmouths have began nesting early. Some laid eggs on the 12th August, three weeks earlier than recorded in previous years. However, in the past week or so there have been some very wet and windy days, with snow lying in the nearby hills, and heavy snowfall in the Snowy Mtns, where I have just had a great day out on the snowboard.

Other birds which had built nests did not lay, and they have been sitting nearby, probably waiting for warmer weather to return before laying. I expect things to pick up again this week as there is warmer settled weather coming in.

A female frogmouth sits in a more sheltered spot in the lee of a tree stem while her mate sits on the nest above.

Greenshank sighting

One of the adult greenshanks which we caught in Sutherland in May has been seen on the tideline of the River Stour at Mistley, south-east England. The bird was spotted and photographed by John Keep.



Here is a photo of the bird being ringed by Ruth Croger.

And a map showing the ringing and sighting areas, where this bird was seen and another which was caught at Montrose last autumn and controlled in Sutherland in May.

This colour-ringing project is being co-ordinated by several Greenshank enthusiasts and records of other birds ringed and re-sighted can be accessed via The Greenshank Migration Story website at

Many thanks to Pete Potts for organising such a fulfilling study.

Ringing golden eagle chicks


I spent Monday ringing golden eagle chicks with Ewan who is studying their habitat use. All three nests were in Scots pines and there was only one chick in each, which is unusual for the area they live in. They often rear three chicks as there is abundant prey in the area, mostly mountain hares, red grouse and ptarmigan.

Ewan climbing up to one nest which requires skilled rope-work to do so safely.

Me with a five-week old chick. The eyries are so large that there is plenty room to sit on the nest along with the bird.

Two plucked red grouse lie in the nest with the chick.
