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.

Playa Espumilla; where Darwin walked

A highlight of my recent life was a week in the Galápagos Archipelago; so much to say about that, but for now I'd just like to share an amazing morning's experience on Santiago Island - not that much happened, and it wasn't the most spectacular scenery or wildlife we saw, but it moved me for a very particular reason. 
The (faint!) pink arrow in the centre of the map indicates the location of
Playa Espumilla ('Foamy Beach') on Santiago.

Looking south along Playa Espumilla.
On 8 October 1835 a young Charles Darwin went ashore on this beach, accompanied by Surgeon Benjamin Bynoe and "some servants". They spent a week on the island, including a visit inland to some Spanish fish-dryers and tortoise flesh salters.

He commented that the Land Iguanas were so numerous that "we could not for some time find a spot free from their burrows on which to pitch our single tent". (These were nesting burrows.) Sadly Land Iguanas are no longer to be found on Santiago.

Darwin also commented fairly matter-of-factly that a few years previously a party of sealers had murdered their captain - "and we saw his skull lying among the bushes"! We did not see his skull, but we did see others, which were those of feral goats which had been on the point of destroying the entire island ecosystem when they were systematically eradicated from Santiago by the end of 2005. It was an astonishing feat, removing every single one of 80,000 goats from 60,000 hectares; such a scale of feral animal removal had never before been attempted and it inspired land managers elsewhere with an example of what was possible. As a result the vegetation, which had previously been eaten to the ground, has now recovered magnificently.

Espumilla is also significant as a Green Turtle nesting site.

Darwin - and many since him - commented too on the tameness of Galápagos wildlife; that hasn't changed.

(The legs are Australian, rather than Darwinian; or perhaps both...)
Given the turn-over of beach sand, I know that my sandals probably didn't tread on a grain that Darwin's did (in fact I'm probably more likely to have in my lungs a molecule of oxygen that he breathed), but they might have... And that excites me.

BACK MONDAY

We've been watching the new Attenborough on the Galapagos -- terrific stuff (although a teensy mistake about penguins).
