The Three Capes

 Tasmania

A four day, three night trip around the Three Capes Walk on the Tasman Peninsular. 

Cape Raoul lies behind Mount Brown at sunset on the first night.

Tasman Island off the tip of Cape Pillar, with the jagged rib of the Blade rising towards the island.

The lighthouse on Tasman Island is picked out by sunshine. The rocky pillars on the right form the Blade, a spectacular highpoint above the sound. The island is mostly bare of tall vegetation since its forest was cleared for firewood by the lighthouse keepers and eaten by their stocks of sheep, goats, cattle and pigs. The light was first lit in 1906 and automated in 1977. Shrubs and small trees are slowly reclaiming the land, and the island's breeding populations of Short-tailed Shearwaters and Fairy Prions are recovering after near eradication by feral cats, which were descendants of the lighthouse keepers pets.

A single block of rock lies on the tip of the Blade, with wrap-around views of the peninsular and the ocean beyond. The main rock in much of the Tasman Peninsular is dolerite, which fractures along straight vertical lines to form crude hexagonal pillars. Hence the name Cape Pillar, although all three capes have these rock formsations.

Day four began with a view of Cape Hauy from the Cape Pillar. The trees are much taller on this eatsern, leeward side of the peninsular.

The view back south to Cape Pillar from Cape Hauy, with Tamsan Island peeping over the ridge. The rock stack is Cathedral Rock.

The view from the end  of the third Cape, Cape Hauy with the pencil thin stack of the Totem Pole, the thicker and taller Candlestick, and the Lanterns. The lanterns are two tall rocky islands off the tip of the cape, one is behind the other.

The Totem Pole is a remarkable 65m tall rock stack. It can be climbed at trad grade 24, although timing access is critical as can be seen by the tide swirling around its base. 

Most people simply enjoy the view. A magnificent view of a wonderful wild place. 

 Black Mountain Peregrines

This is the Telstra Tower which stands on top of Black Mountain, a hill, about 1km from the city centre of Canberra. It is surrounded by Red Stringybark/Scribbly Gum forest which holds lots of nest holes for various animals including Galahs, Crimson and Eastern Roselas.

Two days ago, I was walking through the woodland at the base of the mountain, when I saw an adult female preregrine soaring low over the canopy, obviously hunting. It is usually Brown Goshawks that I see hunting there, so I was a bit surprised.

The woodland canopy was busy with migrating Silvereyes and Yellow-faced Honeyeaters on migration down from the higher Brindabella Mountains several kilometres away. And there were numerous rosellas sitting outside their nest holes, staking claim prior to the next breeding season. So there was abundant food for the peregrine.

Then, the next day, I was walking around the summit of Black Mountain when I heard the distinctive harsh calls of a peregrine coming from the tower. Sure enough, there were two adult birds perched on the second top section, on the supporting struts for telecoms antenae. Yes they are in the picture above, but it is not the best of shots, taken with a phone.

The tower is 195 m tall (640 ft) and an obvious man-made feature to attract peregrines. Yet, this is the first time I have seen them there, or heard any. The tower has been closed to the public for a few years, so perhaps the quietness has helped to attract the peregrines. Although the visitor pviewing platform is a long way below where the birds were.

Now, the question is, will the peregrines stay to breed on the tower next breeding season?

Frogmouth chick rescue 

Following on from the last post on how frogmouth fledglings are vulnerable to becoming grounded and dying in tall grass, I found such a bird yesterday. I was monitoring the progress of some of my study birds and was expecting them to have fledged the night before. When I went to the nest site, I saw that they had indeed fledged. The nest was empty and the parents were perched on a branch in a neighbouring tree with one chick beside them. That raised alarm in me as I knew there had been two chicks ready to fledge only a few days prior. Usually, when there are two fledglings and they have split up, mum will sit beside one chick and dad with the other. But, there were both parents with only one chick. Where was the other. Unlike in the previous post, when one chick had probably grounded in wet tall grass and succumbed to hypothermia, in this case the grass was tall, but dry, so I reckoned that if a chick had grounded in the tall grass in the previous night, it could still be alive. So I searched for it, very, very slowly, and careful to look down into the grass before I moved my feet. I didn't want to step on it.

As the adults tend to sit with a chick each if they are separated, I thought the missing chick might be directly below where the rest of the family were perched. And yes, it was, and it was alive.

The grass was more than knee deep and thick, so the bird could not climb up, fly up on its weak wings, or even struggle through the dense growth. It would have died if I had not found it.

The fledgling had fluttered about twenty metres before grounding, not far from the nest branch which can be seen in the background.

And yes the chick was not only alive but perky, giving a ferocious sounding growl as I bent down to pick it up. It opened its big mouth wide and flashed its wings to appear powerful and more fearsome than it really was. 

Of course, once the fledgling began to react, its parenst both reacted to my interference. They both hooted aggressively and swooped over me. That is a big commitment for frogmouths as they only fly in daylight under extreme circumstances of danger. Here dad sits above me, watching my every move as I carefully picked up his still-dependent offspring.

The fledgling looked bigger than it actually was. Most of its growth so far had been in bone and feather development. There were only weak muscles beneath all that fluff.

I popped the bird onto a dead branch in the shade below where the family were perched. This is the best thing to do if anyone finds a frogmouth chick on the ground. The adults will be close by watching. Just because we might not see any adults, that does not mean there are none there. These are frogmouths, masters of disguise and they can be very difficult to see when perched motionless in a tree, which is what they do most the day.

The fledgling soon settled on its new perch and as I walked away it faded deeper and deeper into the mix of branches. I reckon it would have been safe and a parent would soon fly down to perch next to it for the rest of the day to defend it.

But how many other fledglings have died this year in the wet and windy we have had.

Three Capes Track - Tasmania

A slideshow of photographs from a recent trip.

The lighthouse on Tasman Island is picked out by sunshine. The rocky pillars on the right form the Blade, a spectacular highpoint above the sound. The island is mostly bare of tall vegetation since its forest was cleared for firewood by the lighthouse keepers and eaten by their stocks of sheep, goats, cattle and pigs. The light was first lit in 1906 and automated in 1977. Shrubs and small trees are slowly reclaiming the land, and the island's breeding populations of Short-tailed Shearwaters and Fairy Prions are recovering after near eradication by feral cats, which were descendants of the lighthouse keepers pets.

This walk was over four days and is on well-laid paths all the way. Day one was short, beginning in dry woodland on the west coast of the peninsula and ending with a view over to Cape Raoul. On day two the path followed the clifftops and then cut inland through heaths full of wild flowers. Day three was spent walking out to Cape Pillar and back to the lodge, taking in the views across the Tasman Passge to Tasman Island. The fourth day was a long one out to Fortesque Bay, through the wetter east coast forest with lush ferns and mosses. Before heading down to Fortesque Bay, a detour leads out to Cape Hauy. That path ends abruptly right above the gap seperating the Candlestick from the mainland. The Candlestick is a very dramatic pillar and would be stunning enough if alone. However, its glory is stolen by the much smaller, singular dolerite pillar of the Totem Pole standing right in the narrowest section of the gap. This pillar is a popular rock climb (65m) although as can be seen, access to its base and return from the summit are difficult and weather must rebuff many long-awaited attempts.

The whole walk is so photogenic that I took too many shots to show here. So, I have collated some of these to give a sense of the walk's atmosphere as it meanders around the peninsula. Every turn in the path revealed another view, flower, tree or cliff. The whole mix was refreshing and I don't have any favourites. Others who have been there too, or plan to go will have their own favourite experiences. 

This slideshow follows the route as described and is merely an illustaration of what to expect. For details of the walk check the Tasmanian Parks and Wildlife Service website: https://www.threecapestrack.com.au/ 

Watch out for the Tiger Snake, it's a black variety sunbathing in the grass.

Tawny Frogmouth chicks:

vulnerable when fledging

Tawny Frogmouth chicks are now fledging in Canberra, and unfortunately there have been some heavy and prolonged rainstorms at the same time. This has caused some chicks to be grounded when they fly between trees and if they stay there, they can be vulnerable to predators such as cats and foxes - both introduced pest species. Every year, people find such grounded fledgling frogmouths and are tempted to take them home to save them. After all, they are the most Instagrammable bird in the world, with their fluffiness, big forward facing eyes and apparent sad mouth-line. See the scientific paper below that describes the relevant study:

Thommes, K. & Havn-Leichsenring, G. (2021). What Instagram can teach us about bird photography and color preferences. i-Perception, 12: 20416695211003585.

This chick was low to the ground, on a fallen branch, but its sibling had disappeared. It probably died during the heavy rain in the previous night after grounding in the tall grass and weeds that are growing all through the woods this year due to the rain. The birds cannot climb up out of tall wet grass and can quickly succumb to exposure. 

It is difficult for me to walk through the tall grass and weeds. It must be deadly for frogmouth fledglings. And I have seen this happen before.

Nevertheless, please do not pick these birds up and take them home. They are not pets. The best thing to do is place them on a nearby branch, up off the ground, as high as possible and walk away quietly, without drawing attention of any predatory birds that might be watching, such as ravens or currawongs. The chick's parents will be watching them, like the adult pair in the background of this picture.

And the chicks have a very good threat display, if they are attacked. Although even that pose makes them very Instagrammable.
