A bearded orchid

The references state that this beard-orchid flowers through the spring into January but it was a bit of surprise when we found one last weekend at Bambra. Actually Barry, the birdwatcher, spotted it while we, the botanists, were sitting next to it at lunch time. Luckily we weren't actually sitting on it.

It's the Purple Beard-orchid Calochilus robertsonii, and it is quite common in this district. We had the reference books out trying to turn it into something unusual but didn't succeed. It's beautiful of course, what orchid isn't?

Lunch

The property owner told our group that they had a resident Red-bellied Black Snake on their property near Bambra. After we'd completed plant surveys, set out the mammal-traps and collected the insect traps we decided to have a look for the snake because they are not usually seen in the area. A snake was found on a dam bank but it turned out to be a dark Lowlands Copperhead Austrelaps superbus. We were delighted to see it catch and eat a frog (click on second photo to view large). We were also surprised to see it swim deep under the water rather than on the surface. PS. For the benefit of non-Australian readers, these snakes are dangerously venemous.

Dragonflies and damselfies

Last week the insects were flying in the long and lush grass on our farm at Homerton, including these three. (I really will have to buy that dragonfly book.) Maybe one of you, my fellow bloggers, will know what they are. Update: The second one is possibly a teneral (i.e. newly emerged) Wandering Percher Diplacodes bipunctata, and the first and third Metallic Ringtails Austrolestes cingulatus. Thanks D.


And today at Bambra these little beauties were patrolling a dam (the same one mentioned in my latest tweet - in the bar at right). Update: I think this damselfly is a male Ischnura aurora (Coenagrionidae).

The thrill of the triller

OMG! I've been watching the birds on our farm near Heywood for 25 years but the last two days have been the best.

Our farm is open grassland paddocks leased to a dairy farmer, and a bush block, the whole surrounded by other areas of bush. The house paddock also has trees and shrubs. After years of drought and dry weather the last twelve months have been about normal (whatever that is now), the rainfall near or just below average. The vegetation has responded well and the pasture looks green and lush - so different to the paddocks around here in Geelong.

We went down to the farm for a couple of days this week and I had a great time observing the birds. They were everywhere, calling all day and building nests. I saw 60 species on our farm - and missed seeing some I normally see so the total could have been higher if I'd got up earlier:) The best were Brown Songlark, Rufous Songlark patrolling the house paddock continually, nesting Sacred Kingfishers, nesting White-winged Trillers in the house paddock, Swamp Harrier (not seen here for many years), Olive-backed Oriole, Horsfield's Bronze-cuckoo, Dusky Woodswallow, White-necked Heron and Tree Martin. I dipped on Restless Flycatcher, Wedge-tailed Eagle, Red-browed Firetail, Grey Currawong, White-eared Honeyeater and Mistletoebird - all of which I usually see.

Because the triller was building a nest in a tree in the house paddock I was able to take my coffee and binoculars out and sit in the shade and just watch. It was fun to see the male triller collecting cobweb, lichen and bark, to see it attacking a Horsfield's Bronze-cuckoo that ventured into the nest tree, to see it sitting on the nest (to try it out for size?). I never saw the female. Unfortunately we couldn't stay to see the next installment. And I didn't have time to search for the Rufous Songlark's nest - I'm guessing it was or will be in the long grass near the fence. We're back there over New Year but all the fun will be over by then. Maybe.
