Remembering Namadgi: celebration of a great park #4 bigger animals

We have now got to the final instalment of this celebration of a great park, Namadgi, which is Canberra's back yard. Sadly it has been grievously burnt in the past few weeks, but the fire is effectively out now and recovery has begun. I had hoped to get permission to accompany parks staff into the area to report to you, as I did in 2003, but it seems this is not going to happen. Meantime the park, including the unburnt areas, is going to remain closed for an indefinite period. If you've just found this series, you might like to go back to the start for background that may be of interest.

Today we're going to enjoy some of the bigger animals - the vertebrates (mammals, birds and reptiles - I don't have any Namadgi frogs or fish to offer you, unfortunately).

Male Eastern Grey Kangaroos (Macropus giganteus); young males sparring, Gudgenby Valley.
This valley is in the central east of the park, mostly treeless (a combination of frost hollow and clearing
by 19th and early 20th century settlers) and hugely attractive to big mobs of roos. It burnt, but I'm
assuming that they will recolonise as the grass regrows with the rain.

A small part of the mob we passed through on an autumn walk a couple of years ago.

They're not the only macropods in the park of course, though the others don't normally gather socially. (For a lot more on macropods - kangaroos, wallabies and their kin - see here.)

This was the largest collection of normally solitary Red-necked Wallabies Macropus rufogriseus that I recall seeing.
They'd come to feed one morning on the grass at Bulls Head picnic area in the high Brindabellas.

Reptiles are easy to see on any summer walk (assuming it's warm of course, never to be presumed in the Alps). Skinks are the most likely reptiles to be seen; most are small and quick, but one giant skink is a special attraction.

Blotched Bluetongue Tiliqua nigrolutea by the Mount Franklin Road. This lovely lizard is truly a giant
among skinks, growing to 45cm long and weighing in excess of a kilo. In Tasmania it is found at
sea level, but as we go north on the mainland it is found at higher altitudes.
(More on bluetongues here.)

Black Rock Skink Egernia saxatilis on granites along the Yerrabi Track, in the south of the park
by the Boboyan Road. Much smaller than the bluetongues, it can still get to 25cm long. It lives in
rock crevices and can gather in big numbers in suitable habitat, such as the great granite
tors above the Orroral Valley.

Highland Water Skinks Eulamprus tympanum are found high in the northern Brindabellas, including
here at Bulls Head. They are common on logs or rocks, and often near water - this one wasn't though.

Grass Skink Lamprophilus guitchenoti, Rendezvous Creek walk.
This common little skink (only 90mm long) is found at all altitudes in the ACT.

Snakes are not uncommon, but mostly shy and rarely encountered. In summer though Highland Copperheads are likely to be out on the roads on sunny days.

Highland Copperhead Austrelaps ramsayi crossing the Mount Franklin Road. This is a venomous snake, but
easy-natured and eager to get away. It specialises in high mountain living (it is rarely found below 700m above seal level), so can function at temperatures which would immobilise most other snakes. Its main culinary interest is frogs,
though it doesn't mind small mammals, lizards or snakes if they're available.

White-lipped Snakes Drysdalia coronoides (here on the Yerrabi Track) are even more tolerant of the cold
than Highland Copperheads, living above the snow line in Kosciuszko National Park.
They are remarkably variable in colour (I love this reddish form) but the white lip is constant.
Rarely exceeding 40cm in length, they focus on skinks and frogs.

Which brings us to birds, which are of course a conspicuous part of any landscape. I shouldn't be surprised to realise how many of the following bird pics were taken in the lovely little woodland patch immediately behind the Namadgi Visitor Information Centre - it's after all one of my favourite birding sites in the ACT. Unfortunately it too is closed to the public at present; I understand why most of the park needs to be inaccessible at the moment, but this one I find a little puzzling. It's on the northern fringe of the park not far from the suburbs, with easy access, and thus escape in emergency. It wouldn't seem to be hazardous on days that weren't high fire risk, and wouldn't put strain on parks staff. However, they have enough to think about at present. 

The next eight pictures were all taken there on various visits, mostly in the early mornings.

Grey Currawong Strepera versicolor. This is not a common bird in the ACT, though it is perhaps occasionally
overlooked among the far more abundant Pied Currawongs. Its ashy plumage and ringing calls, sometimes
like metal on metal, are very distinctive though.

Leaden Flycatchers Myiagra rubecula (female above, male below) at their next in a tree fork,
as is characteristic of the species. Its harsh froggy calls and clear whistles are sounds of
the woodlands in summer; in winter it migrates north again.

 

Rainbow Bee-eater Merops ornatus with dragonfly, a staple of their diet, being large and nutritious.
Another migrant which arrives here to breed over summer, though it excavates burrows in banks.

Speckled Warblers Pyrrholaemus sagittatus on the other hand are sedentary, staying in the territory
all year round. Like other woodland species they are threatened by the loss of habitat, and listed
as Vulnerable in surrounding New South Wales (though somewhat mystifyingly not in the ACT).
This one was very busily collecting next-building material...

... as was this Spotted Pardalote Pardalotus punctatus, an abundant tiny bird which lives by gleaning
tiny animals from the foliage. It is common from the Snow Gums to the suburbs.

The exquisite little White-throated Gerygone Gerygone olivacea is another summer breeding migrant.
It has one of the most beautiful calls in the bush, a repeated falling silver leaf of sound.
Sometimes it can be maddeningly elusive, at other times it is totally confiding

White-throated Treecreepers Cormobates leucophaea are on the other hand present all year round, working
from the base of the tree up the trunk, then flying down to the next one.
Its incessant clear piping calls make it relatively easy to track down.

Another good woodland birding area in Namadgi is further south along the Boboyan Road, around the Glendale works depot and along the Old Boboyan Road in the nearby Gudgenby Valley (where the roos above were). The fires went right through there, but I have no idea how intensely, or how patchy or otherwise it was. In general I'd expect woodland to recover reasonably well (as it did after 2003).

Given the overall state of woodlands, it's to be expected that several species reliant on woodland are listed as Threatened; the first two species below are in that category.

Male Scarlet Robin Petroica boodang; there are not many sites in the ACT these days where we can fairly
reliably see these brilliant little insect-eaters.

\

Diamond Firetail Stagonopleura guttata; a delightful little grass-finch, to which this photo certainly doesn't do justice.

Common Bronzewing Phaps chalcoptera, a common pigeon from Canberra to the high Brindabellas.
This one was sunning on a rock outcrop in the Gudgenby Valley.

Immature Fuscous Honeyeater Ptilotula fusca; not common in the ACT in general, but
this area is a hotspot for it. Adults have a black bill and a black and yellow cheek stripe.

An even younger White-naped Honeyeater Melithreptus lunatus, just out of the nest.
It is a long way from gaining its smart black cap and red eye-ring; this is not really
a woodland bird and I'd more expect to see it in the wet forests of the ranges.

The last three Namadgi birds featured here are found high up in the Snow Gums in summer, though at least two move downslope with the snows.

Female Spotted Quail-thrush Cinclosoma punctatum, Mount Franklin Road. Some claim that these are hard to
see, but if you drive slowly through the Snow Gums and look ahead you're very likely to see a pair
scurrying off ahead of you. We don't seem to know a lot about their movements but there is some evidence
that they stay in the high country all year round.

A very young Australian Raven Corvus coronoides perched on a Snow Gum.
Note the grey (not white) eyes, the short tail and short bill with coloured gape,
which helps the parents aim food appropriately!

And lastly, perhaps the bird of the high Brindabellas in summer, the dashing Flame Robin Petroica phoenicea.This male is carrying food to the nest, hidden in a bank. Compare his orange-red to the post-box red
of the Scarlet Robin above; also note that his red goes right up to his beak,without the black bib of the Scarlet.
In winter the Namadgi Flame Robins descend to open country around Canberra.

So that's it for our tribute to wonderful Namadgi. Hopefully those responsible will relent and let us back to this grand peaceful landscape earlier than planned; many of us need that. Meantime I hope this series can help tide us over until that date comes.
