Bridgewater

When I was a kid our family would occasionally go to see the blowholes and the petrified forest, the limestone cave, the sand dunes, the dune lakes, shelley beach and the swimming beach at Bridgewater. They are all within cooee of each other so it was easy to drive from one to the other, and it was less than an hour from home. I remember once we went there on a school excursion because the geology is interesting and diverse enough for a full day's expedition. And it's beautiful as well so that was a bonus.

Bridgewater Bay and Cape Bridgewater
Over the years we've visited Bridgewater Bay occasionally - there is a Surf Lifesaving Club there so it's a safe beach for kids and surfers and we've walked to see the seal colony on the cape. But it's quite a while since we've been to the blowholes and the petrified forest on the cliffs west of the bay. The cape is clifftop sand dunes over basalt and when you visit the blowholes area you can clearly see the geology, and now there are boardwalks and paths and lookouts and explanatory signs so you can understand what you're looking at. And it's not as dangerous as it was when I was a kid. Our parents were always telling us to stand back from the edge of the cliffs.

I was busily explaining the geology to the relatives we'd taken to visit the area, telling them that the sand dunes had covered a forest of trees and the calcified remains are now exposed, when we all read the explanatory sign at the same time. Oops! The header on the sign reads 'The petrified forest that isn't'.

The track

Welcome Swallows and Martins, basking.
There's a track winding back, dividing the farm to provide easy access to the paddocks. On any day in summer, on this particular curve, I can guarantee you a big bunch of swallows and martins just sitting on the gravel, a pair of Blue-winged Parrots and a pair of pipits.

It's a mystery to me because it looks just like every other part of the track.

Titan Arum

This is what my daughter and I did on our way to my brother's place for Christmas lunch.

We had to drive from Geelong to Ringwood so it was easy to leave a bit earlier and on the way visit the Tropical Glasshouse at the Melbourne Botanical Gardens. Why? To see the flowering Titan Arum Amorphophallus titanum.


Quote from an information board in the glasshouse: After seven years of careful nurturing by Royal Botanic Gardens' staff the stunning Titan Arum, also known as Corspe Flower, is expected to reach full bloom during the week of Christmas. This extraordinary plant has the world's largest unbranched inflorescence, featuring a cluster of small flowers inside the base. The exact day of the bloom is difficult to determine, however once flowering the inflorescence may only last two or three days before collapsing... the Titan Arum is currently growing at a rate of 10+ cm a day and is expected to reach a height of 2-3 metres in height.

The flower has not yer opened. You can see that the inside of the frilled skirt that is yet to drop is deep purple and it doesn't have any odour as yet. Look carefully at the photo above. The tall green plant to the right of the picture is in fact another specimen of the Titan Arum but is at an earlier stage of development. That plant will die down and then the bulb will be dormant for possibly years before the flower spike emerges.

To keep tabs on the status of the flower the Botanic Gardens' Facebook page has the best information. And here's what it will look like when it opens in the next day or so.

It was a bit tricky getting good photos of the plant. Too many people, and the high humidity in the warm glasshouse kept fogging up the lens on my camera!

Lake Victoria

Find Emily Street, Point Lonsdale on Victoria's southern coast. Go right to the end, where there is a small carpark, and walk through the gate. The walking track takes you right out between the shallow waters and roosting areas of Lake Victoria that wading birds love.


We were there yesterday because it is one of our stops on the annual Challenge Count. There were a lot of birds there--LBJs (little brown birds such as Curlew Sandpipers and Sharp-tailed Sandpipers), Banded Stilts, ducks (including a single Freckled Duck), swans, dots (Red-kneed and Black-fronted Dotterels), pelican and spoonbills. It's heaven for a birdwatcher.

Mystery objects, Lake Victoria ...

... and the more normal view of juvenile and adult  Banded Stilts.
PS Best bird, for me, on the Challenge Count was a small flock of delightful Horsfield's Bushlarks singing and occasionally flying in grassland at Connewarre. Thank goodness it wasn't up to me to identify them. I had no idea, but others in our group knew what they were.
