Best Photograph 2020

Lumholtz's Tree Kangaroo Dendrolagus lumholtzi, Atherton Tableland.

We all know 2020 has been a terrible year and I have noticed that I have posted much fewer articles this year than most. This is a result of me not having traveled so much this year, none internationally. But in November the state borders opened in Australia and I was able to go on a field trip to Cape York, stopping for a few days on the Atherton Tableland in north Queensland. And that was where I spotted this lovely animal high up in the rainforest branches.

These are not the sharpest of shots, but not bad for a hand held long lens in dull light. It is the back-lighting on the fur and leaves that I like, and the pose. The kangaroo could not have held a better pose for me. And I like the detail of the mosses and ferns on the branches, a true wild shot of an animal in its natural habitat.

Although, as it sat there looking down at me, completely at ease in the branches, I was reminded of a similar scene from the movie Predator. I only saw this one kangaroo, I must have missed more. Real life is better than fiction.

Tawny Frogmouths are busy

Many of the tawny frogmouth chicks I have been studying this year have fledged in the past two weeks, like these two above, flanked by their parents. The family were sitting in a tree about 30 m from their nest tree. All were sitting quietly in the partial shade. Mum adopted a defensive hiding pose, adopting a posture to resemble a broken branch. Dad sat quietly, he had seen me often before and probably recognised me as no threat. The chicks were curious.

The chicks, like so many frogmouth fledglings, were so curious of the observer that they never adopted a defensive pose. They stared down at me as if determining what I was, and whether I was a threat to them. They were probably trusting in their parents for guidance. But they simply sat quiet and didn't give any soft alarm calls. Did the chicks feel safe because their dad wasn't alrmed?

Dad maybe looked calm, but I am sure he was ready to react were I to make any wrong move towards them.

There are numerous frogmouth pairs that did not seem to breed earlier, in september, as usual. But I have seen several new nests and birds on eggs in the past week, at the same time as most are fledging. This might be because there was limited food over winter and not all birds were in condition to breed in spring. Now though, with most pairs rearing two chicks, and some pairs rearing three, and it has been a wet spring, it looks like there is abundant food. I found this frog below one nest, and if this is an example of the prey available, that is a substantial meal for a frogmouth chick.

And I found this centipede below another nest. The kinks in the animal's body indicate where a frogmouth had grabbed it. I wonder what they taste like?

Blind Snake killed by Tawny Frogmouth

I found this dead Blackish Blind Snake Anilios nigriscens yesterday below a Tawny Frogmouth nest. It was lying directly below the birds' nest where there were two well-grown chicks, days form fledging. The snake was in amongst the scattering of droppings from the chicks, and there were two distinct pinches in the body, indicating where a frogmouth had gripped the snake when thrashing it against a branch to kill it prior to delivering it to the chicks. There were broken scales on the head indicating this, see image below. 

The nest was on the branch of a Yellow Box Eucalyptus melliodora. The adult male bird on the nest can be seen here against the sky. Less easily seen is the female two branches below.

Blind snakes are only nearly-blind. They hunt by following invertebrates such as ants and termites in burrows and have evolved scales over their tiny eyes, seen here as faint black spots 3-4 scales back from the snout. They seldom venture above ground except after rain, and 27 mm of rain fell in Canberra in the 48 hours previous to this find. Its burrow had probably been flooded. On one of these wet evenings, I watched another frogmouth hunting small invertebrates on the edge of a road. It sat on a sign post or branch and watched for prey to move. There were obviously plenty, as the bird only sat on a perch for a less than a minute at a time before pouncing down and carrying off some small animal to its young back at their nest. This snake, at 44 mm long, would have been an easy find and capture. 

Blind Snakes are almost defenseless against such attacks. They have very small mouths and cannot bite like an elapid snake. They can twist and turn, and release foul-smelling odour, but neither of these strategies would protect it against a frogmouth. I do wonder though, why was it lying below the nest. This is the largest snake recorded to have been killed by a Tawny  Frogmouth, twice the size of the previous record. Was it too large for a chick to swallow. Or had it been dropped between adult and chick by accident. I believe the latter scenario, as such a large snake must have been difficult for the birds to maneuver between mouths, especially inexperienced young mouths. 

Canberra Spider Orchids

Arachnorchis actensis

The orchids in and around Canberra are flowering really well this year after high rainfall in autumn, winter and spring. In the past week I have seen several species in flower, the more common ones in thousands on Black Mountain. Even some of the local specialties have been out in high numbers. And I have seen several groups of the local endemic Canberra Spider Orchid, with a total of over thirty flower spikes. By far the most I have ever seen.

A little group of Wax-lipped Orchids Glossodia major.

At only about 10 cm tall and with two slim leaves, this Canberra Spider Orchid is easily overlooked in the shadowed leaf litter.

A burst of sunshine helps define the flower.

And the intricate detail of the flower head. A very rare flower. A treasure.

 First Shingleback of the Spring

The weather picked up a bit last week. It was bit warmer, there was blossom on all the fruit trees and many birds are well into breeding mode. And there hasn't been a frost for a while. All enough to encourage the reptiles to come out from their snug winter quarters under logs, rocks and sheds. Enough for this shingleback to take a wander through the woodlands.

I always stop to chat to these lovely lizards when I meet one. They are so harmless, quiet and sort of trusting that we won't hurt them, as they are too slow to escape. I just hope that more people do the same and don't bother them by picking them up and stressing them. Take a good look at them, get to know them, share the bush with them. 

I particularly like how the scales around their eyes fit together so well. The dust highlights this one's features and it's eye is intensely focused on the camera lens -  a big eye from its perspective.

It is obvious how they gained their name, shingleback, the scales along their back fit together like shingles on a roof, and they are just as efficient at casting water. But that dust does tend to get into all the cracks.
