Yellow-faced Honeyeater - a banding control

Yellow-faced Honeyeater : 026-11399

When I was out helping Richard Allen and others mist-netting birds for banding  a week or so ago at the Weddin Mountains in New south Wales, we caught a Yellow-faced Honeyeater Lichenostomus chrysops which had been banded previously elsewhere. We now have the information on where that was. The bird was banded and identified as a first year (1) female in 2011, in the Warraderry State Forest. So it is now a three-year old (3) and has moved 29 km from the initial banding site.  

We use the shape of the alula tip as an aging guide, and we had already designated the bird as an adult (1+) on the basis that it had a pointed alula. Young birds have rounded tips on their alulae.

This is only the 18th record of a banded Yellow-faced Honeyeater moving over twenty kilometres, although for a widespread and abundant breeding bird of south-east Australia, which is known for its spectacular north-eastern orientated migration flocks, little is known on how far they migrate other than birds winter in eastern Queensland. Some birds also spend the winter in the south east, so which birds travel and where. As there are so few records from banding, perhaps attaching tracking devices to some birds would help answer this question. This is a common species yet we do not know its full life story. If a suitable system could be developed, the methods could be adapted to address similar questions on endangered species. For it is important to know where rare birds migrate, or even move locally, in order to conserve their habitat requirements in all parts of their range. Work of this type is well established in other countries and is providing enlightening results.

The bird had moved between two large areas of forest,  with a large area of farmland separating the sites 
Thanks to Richard Allen for organising the banding trip, Graham Fry for first banding the bird and David Drynan of the Australian Bird & Bat Banding  Scheme for the speedy interpretation and return of the data.

Possums on the roof

A very large youngster - soon to be made to walk and climb on its own 
There were footsteps on the roof last night and then someone scratching at the dining room window. It was our local possum, a Common Brushtail Possum  Trichosurus vulpecula, checking out the food tray we put out for the birds during the day. She had a joey on her back as she scrabbled up and down the drainpipe. It was well-grown, about six months old and ready to be, if not already, weaned. Certainly quite a load on her back if she has do a lot of climbing. The youngster should be off and walking, climbing on its own any time soon, but will still be dependent for perhaps another year before it is cast out of the home range.

Mum raids the birds' food tray
As there was nothing left in the feeding tray we put out a slice of bread and raspberry jam. Mum sniffed it from the roof and came straight down for it. Snatched it, and climbed back onto the roof to eat it. meanwhile the joey had to climb up on its own, perhaps for the first time. It wasn't very agile on the overhang moves. But they won't take long to master.

A special treat of jam on bread -only the best organic for them

Lemon Cap orchids

Lemon Cap Orchid  Stegostyla cucculata
I have been out and around Black Mountain quite a bit recently, but have not found as many orchids in flower as I had hoped. The most abundant species over the past week has been the Lemon Cap Stegostyla cucculata, a small plant, about a foot high stem, with a pale white flower. 

A hoverfly approaches the flowers
These plants might be easily overlooked by we humans, but the insects can find them, no problem, probably by following the scent - a citrus one in this case. I was lying down, focusing the camera lens on this one when I saw a hoverfly come into my peripheral vision. It was quick, and precise as it touched down on the petals and took a feed of nectar from the flower. Then was off. All done, the hoverfly was fed, the plant was pollinated and I had a photograph. All happy. Wildlife in action.

And promptly lands on the petals to feed

Fledging time

A full-grown Wedge-tailed Eagle chick stands on the edge of its eyrie
Yesterday, while out helping the with a university survey of woodland birds I was fortunate in being posted to a site near where a pair of Wedge-tailed Eagles have a nest. The single chick in the eyrie was well grown and ready to fly. And what a wonderful launch-pad from which to make one's first flight.

The eyrie is set high in a Blakely's Red Gum
Meanwhile the adults soared around overhead and up over the adjacent hilltop, dipping down to watch me as I walked on out of the area. No doubt they had been watching me all the time.

Secure, secured and a snake

An echidna resting between logs
Today began with a bit of frost and the animals were a bit slow to get going. I took part in a local university woodland bird survey soon after dawn and was finished by about nine. After that I went and checked on a couple of Tawny Frogmouth sites.

I always keep my ears as well as my eyes tuned, to the sounds of the bush, and while walking quietly through the woods I heard the distinctive scuffling of an echidna. It was about fifty metres away and I watched as it walked over to a log and promptly burrowed into the litter. And that was that, off for a nap. If I hadn't heard it I doubt if I would have seen it, so well hidden between the logs and leaf litter.

They really tuck tight into corners or hollows
I wonder if any predators would find it in such a secure hiding place, or if any would bother to try and open those spines for a meal?

Who would want to tackle these spines
Then just a hundred metres on, I heard a commotion at an old fence which runs through the wood. Eastern Grey Kangaroos are common - abundant - in many of the Canberra woodlands, and a joey had managed to twist a leg through the wires of the fence. Its mother was standing right over it as it tried again and again to free itself. But it was firmly secured. So, over I went to try and free it, at the likely cost of a few hefty kicks for my trouble. Then no, I was safe. As I approached from its front, the direction the joey had been travelling in and persisted in trying to get away from the fence, it quickly turned to flee from me. And as it did so it twisted itself free, bouncing through the trees non the worse.

It was quite a large joey and I really didn't fancy a kick from those hind legs, with claws on the end.

The joey's hind leg was trapped through wires of the old fence
My walk wasn't over though and I carried on looking for frogmouths. That involves lots of time spent looking up trees, trying to pick out the birds from the branches they resemble so well. Fortunately, I always keep an eye on the ground too, as that can save one's neck. By watching the ground I find droppings or feathers which indicate that any otherwise non-noticed frogmouth is up above. Then oops, after spying up a tree I turned and took a few steps, and just noticed an Eastern Brown Snake exactly where I was about to drop my left foot. The snake must have been slow to warm up after the cold night, for I don't usually first see them so close, but luckily I didn't hurt it. Although it didn't like me about to tread on it, so it shot away down its burrow about a body and a half's length away - not quite two metres.

An Eastern Brown Snake - not the one I found today, that one was too quick off the mark to photograph
