Wetlands in winter – a compilation.

Ducks, Pink-eared

 

Winter at the Wetlands is quieter of course, but still lots going on. The Pink-eared ducks are more common in winter, and this pair made sure there were no easy targets for the icy water and winds. (A brilliant line in a 1926 government publication aimed at encouraging people to come to the new Capital: “the wind, coming from the south, is shrewdly searching!”).

This juvenile Pacific Black Duck looked and sounded plaintively lost. If you look closely, expecially at the first photo, you can see its little beak babbling with a plaintive “mummm?”

What I thought, a few weeks ago, was a first sighting of a Yellow-plumed Honeyeater, rather on the edge of the normal habitat, turned out on a better sighting the other day to be a Fuscous Honeyeater, also though my first sighting of this bird.

The Black-winged Kites are nesting again, and the search for food has been quite prolonged.

The Grey Teal had sole use of the preening log, probably because it would be freezing up there.

As always there were plenty of Fairy Wrens. There were also plenty of Silvereyes and White-browed Scrub Wrens:

Away from the water, my first sighting of a White-naped Honeyeater, and some Spotted Pardalotes:

Unusually, perhaps also lost, was a single adult male Red-rumped Parrot:

Little Grassbird

You’ll hear them, but you will never see them. That seems to be the conventional wisdom. But I did see them, and, admittedly serendipitously, one of many random photo attempts came out.

 

Grassbird, Little

This is taken on a walk worth doing at Point Cook, between Geelong and Melbourne, on the edge of the Bay. It was a very cold and extremely windy day, so birds were uncommon. But well worth going back to on a nicer day.

The ubiquitous White-faced Herons featured. I believe there is a global system they have in place, to ensure there is a least one at every water hole. This appears to be in breeding plumage.Heron, White-faced br

Box-Ironbark forests near Chiltern, NE Victoria

IMG_2299 (2)The Chiltern Mt Pilot National Park, in central north eastern Victoria, displays the remnants of the Box-Ironbark forests which dominated this area before the English saws and axes arrived.

Over 2000 years ago, an artist painted with red ochre this image of a thylacine (tasmanian tiger). It is extraordinary that it could still be visible – if only just.

IMG_2308 (2)IMG_2307 (2)The canopy is very high in the rejuvenated forests, the last bushfire was only a few years ago, and the birds were about but generally right up there.

I didn’t see the rare Regent Honey-eater, but did see a few White-naped ones

There were several Robin families, with the Scarlet Robin (the crimson chest is less complete than for the Flame Robin) and the Eastern Yellow Robin:

There were several Brown Tree-Creepers, confusing the issue by creeping across the forest floor, rather than up a tree. I have not seem them so closely before. This looks like a non-breeding male; unusually in this species, the female is more colourfully striking than the male.

I saw several parrots which I have not seen before, but they were all too quick for the camera.They looked like Turquoise Parrots.

Definitely my first sighting was of a Crested Shrike-Tit. It had clearly been to cockatoo school to learn how to attack bark

IMG_2303 (2)IMG_2299 (2)IMG_2298 (2)IMG_2295 (2)Other things of interest in the area include the memorial to Major Thomas Mitchell who, unlike many ignorant European explorers, didn’t actually “pass” here, but went past here; and the Chiltern Golf Course, which seems to  have, from accounts of a number of other observant travellers, a wise policy of ensuring no actual golfers ever harm the well manicured course.IMG_2226

Getting away from the water at the Wetlands

Went for a wander in the forested ridge near the Jerrabomberra Wetlands. Lot of activity, and as is often the case, a couple of trees apparently full of Silvereyes turned out to contain myriad species.

The Silvereyes were plentiful:

IMG_2115 (2)

There were so many you could miss the many other birds in the mix.  Two Honeyeaters which I had never seen before, and both of which were well on the edge of their normal habitat, were the White-naped Honeyeater, and the Yellow-plumed Honeyeater.  The latter was very hard to pick, especially given it is right on the edge of its habitat, but the darker bit on the end of the yellow beak certainly suggests a young Yellow-plumed Honeyeater.  After all that, having seen more playing about today (mid July) I think it is a Fuscous Honeyeater, extremely similar but more likely to be here.  Today’s photo added below.

The adult male Spotted Pardalots are certainly very colourful.

Many other familiar birds were about including Red-Rumped Parrots, Pied Cormorants, Superb Fairy Wrens, White-browed Scrub Wrens (below), and Australasian Darter (also below).

Canberra and astrophysics

Have got into a few space related things lately.

First, the Mr Squiggle coin issue exhibition at the Australian Mint. Overseas people would do well to research this iconic Australian tv show of the 60s, noting the sophisticated dialogue: for example, Blackboard’s intellectual contribution was “Hurry up, hurry up” in a scary deep voice, as poor bewildered Mr Squiggle (being a man from the moon) tried to draw his picture (nose pencils were notoriously unreliable back then) under the comforting guidance of Miss Pat.  In more considered moments, he (Blackboard) just says “Hrrmmp.”

 

Next cab (well rocket) off the rank was a tour of the Mount Stromlo Observatory, in Canberra. The tour was led by the famous astrophysicist and cosmologist, and most entertaining, Dr Bradley Tucker.

The Observatory, one of our proudest government services, was started back in 1911 with the Oddie Telescope, jointly funded by the newly created federal Government and private astronomers. Much to the Government’s surprise, when they offered to part fund the telescope, fully anticipating that the rest would never be raised, the astronomers already had pledges of enough to provide their half. Like most things up there, it was destroyed in the 2003 bushfire. This was the first federal government funded building in the Canberra region.

IMG_1476

After the bushfire, the decision was taken to move the telescope function to Coonabarabran, some 700km away, and build more cutting edge facilities on Mt Stromlo. The telescope data still comes back to the mountain for analysis.

There is a laser which operates 24/7 destroying space junk, of which, apparently, there is a shitload. The laser can be seen physically changing position to shoot the next target, and at night time one can see the beam firing in the dark. It doesn’t seek to destroy the object directly, which would lead to millions more items whizzing around the planet at 4000kph. Rather it hits the front of the object, which leads it to stand “upright”, then gravity draws it back into the earth’s atmosphere, which burns it up. Neat what.

IMG_1481

Another facility provides GPS, and this about to be upgraded via a new satellite, in the next few months. Extremely accurate positioning will be available.

IMG_1478

The new focus is on building and testing satellites. Amazingly satellites are now the size of a standard tissue-paper box. There are vibrating tables, severe heat/cold testing chambers and other testing facilities, all maintained in astoundingly dust free conditions.

IMG_1501IMG_1497

Any doubt about how hot the bushfire was is dispelled by the fact that the lead and aluminium melted, 300°C and 650°C respectively.

IMG_1488

As in all bushfires, some things somehow escaped, but not much.

IMG_1486

Next space related trip was to our Museum of Australian Democracy (better know as old Parliament House).

There was an exhibition about things which happened there at the time of the first lunar landing, in 1969, in which Australian radio telescopes (Honeysuckle Creek, Tidbinbilla and Parkes) played such a key role. Anyone who hasn’t seen The Dish should do so forthwith – a brilliant example of Australian comedy; just remember it was Honeysuckle Creek, not Parkes; and, sorry for serious disillusionment, no they didn’t really play cricket on the telescope dish.

Amongst the oddities were extracts from Hansard, demonstrating the novelty of space things; such as if we get the tv signal from a russian satellite, will it be in russian.

I only recently heard that there is a giant radio-telescope near Canberra – MOST, which stands for Molonglo Observatory Synthesis Telescope. It is of course pretty obvious from that description what it actually does so I will leave it there. I went to an exhibition on the scope in the Queanbeyan Library. It is quite an important installation, and has recently detected strange radio wave signals from way out there.

It consists of two “wings”, each about a kilometre long, with collection and analysis facilities in the middle.

 

Today, in a variation (sic) on a theme, I went up Mount Stromlo to a series of chamber music concerts. They were part of the Canberra International Music Festival, and featured three world premieres plus some Bach. Luckily some concerts were indoors to enable thawing, or we would have had 200 frozen bodies up there. The two violinists, who asked for volunteers to blow warm air on their hands, were thrilled when it started to sleet and we all “had” to pop inside for the final concert. Great idea though, and, if it had been on any other day of the last few weeks it would have been still and 19°C.

Going where no man (well not recently) has been before

IMG_1833Last week I went on a very interesting tour of the Old Parliament House in Canberra. The tour was built around the lunar landing of 1969, and the activities in Australian government concerned with that event.

We heard some astonishing, but not surprising, excerpts from the Hansard – the records of the parliamentary debates. eg Mr Speaker, if we are receiving tv signals of the landing via Russian satellites, will they be in, well, Russian! General laughter based on embarrassed ignorance.

We visited several sites within the building featured in the brilliant lunar landing film “The Dish”, including the use of the Clerk of the Senate’s office to be the Prime Minister’s office, hoping no one notices that the carpet is red, when the PM’s would be green.

A clear highlight was to be able to go onto the roof, which provided a rare opportunity to see behind the iconic statues facing out from the front of the building, as well as other connections.

MULLIGANS FLAT, CANBERRA

An inspired move in the ACT is to create reserved forests and grasslands right through the territory, to assist migrating birds and small animals, and to preserve our wildlife. Two protected areas are the Sanctuary, at Tidbinbilla in the far south, and Mulligans Flat in the far north.

Mulligans Flat has seen the release, and re-generation, of the Eastern Bettong which had become extinct in these formally prolific parts. Behind the fence, they are secure from cats and foxes (as long as visitors make sure they shut the gate!), and are doing very well. During the day they won’t be seen, but their houses are quite evident. They cut and chomp a “cave” inside grass clumps, as can be seen in this photo.

IMG_1865

Also being re-introduced are the Eastern Quoll and the Bush-stone Curlew.

The App is excellent and gives great information about various features of the many walks in the reserve. From this I learnt that there are two basic types of eucalypts – thick barked and smooth. So the red-barked gum (first photo) has a thick bark, which, in the inevitable bushfire, burns slowly so keeps the key workings cooler so they have a better chance of survival. The Brittle Gum (second photo) has a very smooth surface, so the fire doesn’t get a good hold on the tree, hence again the key workings are kept cooler.

After about 150 years, the app told me, the termites finally gain traction in terms of eating the tough fibrous insides of the gum’s branches, and the outer branches start to die. This might also be driven by cataclysmic events such as a super hot fire. Interestingly, according to the App, eucalypts grown in other countries do not suffer the same fate. It is surmised that the termites in Morocco, Spain, Equador et al have not evolved – yet – to be able to eat the very tough eucalypt fibres. In Australia of course, nature being nature, the dead branches drop off or open up to provide housing for birds and small animals.

There are a number of large ant nests, in which the Echidna revel:

I saw my first ever Varied Sitella (in this case of the chrysoptera orange-winged sub species); they are, even within the same sub-species, well, varied – which is just as well or they would have to change the name; they are the next three photos:

Sitella Varied chrysoptera2Sitella, Varied chrysoptera orange winged femSitella, Varied chrysoptera 3

and also first ever Speckled Warblers – the first two are males (blacker line across the side of the head above the eyes) and the one on the ground a female (much lighter line above the eyes).

Also spotted was a Flame Robin, which is striking both from the back and the front:

An interesting feature of this area is the old coach road which ran from the belconnen estates to braidwood and sydney. The original track can still be seen here:

old coach roadAs always, one I had a lot of trouble identifying but am pretty sure it is a female Flame Robin.

A lovely spot and a tribute to the Government and the rangers.
