The last frogmouth chicks have fledged


The last broods of tawny frogmouth chicks in my study areas have now fledged. Although there are probably more out there that I don't know about. When there is only one chick, as in the above situation, it is usually the male who keeps close by and protects it.

This single chick was the last from fifty-five territories I monitored this year. Although it has a short tail and wings, it can fly capably between trees and now follow its parents through the wood as they search for food. They will continue to feed the chick for about a month yet as it is not fully developed, only enough to leave the nest site. It is safer for these birds to leave the nest as soon as they can because predators are more likely to find them if they stay in any one place for too long, such as in the nest.

The adult female was up on a branch immediately above them. She is quite unconcerned by my attention because she is familiar with me. Even though I only check on them perhaps four of five times during the breeding season, they are long-lived birds and this bird has seen me often enough over several years to recognise me and know that am not a threat to her or her chick.

In the adjacent territory, another male was sitting close by a single chick. The chick does not know me so it is inquisitive, staring down at the strange human looking up at it, but not alarmed as its father next to it has not given any alarm notice. This chick is about three weeks out of the nest and much larger and further developed than the previous one.

Then a goshawk flew overhead and the local birds gave a chorus of alarm calls. This made the male lift its head and keep alert, although only adopting a partial defensive posture. The chick responded immediately and went a little further into a stick pose. Both birds were wide-eyed and listening to the other birds' messages. Then after a minute or so, the danger had passed and the birds all relaxed.

The female was in a lower branch of the next tree and simply gave me a look as I stood by.

Then she began preening and shaking her feathers, quite at ease in my presence.

The family will move around their territory during the summer and I am less likely to find them again. So this might be my last meeting with her for a while. I left her basking in the sun with her head tilted to catch its rays. They do like to sunbathe.

Tidbinbilla Moths


Emperor Gum Moth Opodiphthera eucalypti  (c 15 cm wingspan)

I was out at Tidbinbilla Nature Reserve last week helping with a moth survey organised by Glenn Cocking and Suzi Bond for their book on moths of the Australian Capital Territory. The site was well sheltered beneath tall eucalypt trees and I managed to photograph about a dozen species. Here is a small selection of the ones I photographed. It is the colours and form that appeal to me. Knowledge of these species is so sparse that I cannot fill out the text to tell more about them, especially their lifestyles, habitats and foodplants. Hopefully that will all be in the book.


Melanodes anthracitaria dark phase (c 5 cm wingspan)

This rather ordinary moth is worth a mention because it occurs in two colour forms; a dark all grey phase, and light phase of grey blotched with creamy/yellow.


Melanodes anthracitaria light phase


Hypobapta sp. from above (c 4 cm wingspan)

I like to see the moths' tiny faces, antennae and those big round eyes. 


Hypobapta sp. from the side/front


Praxis porphyretica (c 4 cm wingspan)


Callitera rotundrata (c 4 cm wingspan)


Cleora sp.  (c 4 cm wingspan)

What wonderful antennae.

Nisista sp. (c 4 cm wingspan)

This species looks so much like a rolled-edged leaf lying on the forest litter.


Endotricha ignealis (c 2 cm wingspan)

This species seems deliberately to hold its forequarters up on its long legs, and its great long antennae are swept over its back.

Parepisparis lutosaria (c 7 cm wingspan)

Finally, this was my favourite find of the night, magnificent colour and form.
