About Me

My photo
Canberra-based naturalist, conservationist, educator since 1980. I’m passionate about the natural world (especially the southern hemisphere), and trying to understand it and to share such understandings. To that aim I’ve written several books (most recently 'Birds in Their Habitats' and 'Australian Bird Names; origins and meanings'), run tours all over Australia, and for the last decade to South America, done a lot of ABC radio work, chaired a government environmental advisory committee and taught many adult education classes – and of course presented this blog, since 2012. I am the recipient of the Australian Natural History Medallion, the Australian Plants Award and most recently a Medal of the Order of Australia for ‘services to conservation and the environment’. I live happily in suburban Duffy with my partner Louise surrounded by a dense native garden and lots of birds.

Sepilok; an oasis in the oil palms #2

Last time I introduced the Sepilok area in eastern Sabah, Malaysian Bornea. With this post I'm continuing that series, but with a fairly brief post, relating to the surrounds of the Rainforest Discovery Centre, which is immediately adjacent to the Orang Utan and Sun Bear rehabilitation centres. 

This is primarily a schools education centre, but the public are welcome. It comprises an excellent interpretive centre and walking tracks through both labelled plantings of rainforest species and primary rainforest. One such walk circles a lake and climbs, via a boardwalk, to a canopy-level viewing tower. Flowering plants around the carpark support a good population of sunbirds. My photos on the whole were disappointing, and some are really not usable, but rather than ignoring the centre I've opted for this short photo essay, covering at least three visits there over two years. 

The forest itself is superb, especially as experienced from the boardwalk and viewing tower. Here are some views of it.


I really can't get enough of tropical rainforest!
The dipterocarps are members of the family Dipterocarpaceae, nearly 600 species of rainforest trees found throughout the tropical forests South America, Africa and Asia, but Borneo is their hotspot. There, you have a very good chance of getting it right by identifying a rainforest tree as a dipterocarp!
Parashorea sp., Dipterocarpaceae, Rainforest Discovery Centre.
Cauliflory on Sterculia megistophylla, Family Malvaceae (formerly in a smaller family, Sterculiaceae,
but in common with the current ways of botanical taxonomy it has been engulfed into a massive megafamily,
with arguably a loss of nuanced information).  Cauliflory ('stem flowering') seems to be a method of offering
flowers and fruit to pollinators and dispersers, though its advantages are not always obvious.
Adenanthera pavonina, a pea family tree, whose flowers are normally way above our heads;
this one was alongside the elevated boardwalk. Parts of the plant have been widely used in traditional
medicine, and there appears to be a fairly sound pharmacological basis to this.
Obviously there are birds present, but as is often the way in rainforests it is not always easy to photograph them. (Still less easy to do so well, though I'd like to be able to have my time there over with my current camera.)
Grey-cheeked Bulbul Alophoixus tephrogenys (at least I'm almost sure of the species, though a bit more
light would have been good). I do tend to  have trouble with bulbuls I'm afraid.
Ashy Tailorbird Orthotomus ruficeps, a common busy little Bornean bird, so named because it constructs
its remarkable nest by sewing the edges of a large leaf together, punching holes and drawing spider web
or plant fibre through them to hold it together.
Female Orange-backed Woodpecker Reinwardtipicus validus. This is a fairly big woodpecker,
and the only one of its genus. He is more colourful.
Eastern Crimson Sunbird Aethopyga siparaja. I almost left this photo out, but he is very handsome...
Lower down are reptiles.
Skink Mabuya (or Eutropis) multifasciata.
Malayan Box Terrapin Cuora amboinensis.
But perhaps the most impressive animal we saw there was a mammal, for which we waited until near dark. The following photos give the impression of more light than was actually present - I used a very high ISO and balanced the camera on the boardwalk railing for a very slow shot in torch light. I'd never seen any of the 'flying' squirrels previously, and this one was magnificent. Our guides knew their day-roost hollow, so we just waited for them to emerge.
Giant Red Flying Squirrel Petaurista petaurista.The 'giant' part of the name is not used lightly;
head and body are over 40cm long and the tail longer still.

After a few minutes it turned towards us and glided directly overhead into the forest, at least 100 metres in the air. It was an impressive finale.

I'll be back next time to complete this celebration of the wildlife of Sepilok.
