Takahe (Porphyrio hochstetteri) are one of the world’s most endangered birds. There are only around 120 still surviving in Fiordland, although a few more now live on predator-free islands off the New Zealand coast. (If you go to Tiritiri Matangi Island in the Hauraki Gulf you’ll be bound to see them.) But while the birds […]

the joys of essay-marking (no, seriously)
One of the benefits of reading (& marking) students’ essays is that you find a whole pile of new papers that are worth reading. (I expect them to go to the scientific literature for information & examples, and support for their ideas, & I will confess to getting just a leetle tetchy when they don’t….) […]
Continue readingculture in chimpanzees
When Jane Goodall observed chimpanzees making tools, it became clear that here was yet another example of the continuum between humans and non-human primates. Use and manufacture of tools was not something that distinguished humans from their close relatives, & chimps could be said to have a form of culture. Now here’s a paper that […]

Of course they can’t – they’re birdbrains! Right?
Continue readinginterference competition in wolves & coyotes
This post is based on an interesting paper that I’ve had in my blogging folder for a while now. The researchers (Berger & Gese, 2007) looked at the impact of interference competition between wolves and coyotes on the coyotes. The study was based in the Greater Yellowstone Ecological Area, & was possible because wolves were […]

At Scicon, Bernard Beckett talked about getting people excited about science by telling stories about cool science stuff. One of his examples was how he told one of his classes about what makes voles monogamous or promisuous. Racy stuff! I remember reading about this some years ago in a book by US author Natalie Angier, […]

On Monday night a newspaper article caught my eye – the reporter had picked up on a study suggesting that, if you’re a female praying mantis, eating your partner during sex can actually be quite beneficial…
Continue readingcool cephalopods
Ages ago I saw an item on TV about cuttlefish – one of the neat things I took away from it was how cuttlefish and other cephalopods (octopus & squid) use colour to communicate, and how precise their control of skin coloration is. And I would tell my students about it, but I didn't have […]

Or should that be 'octopi'? Anyway, I just came across this story, about an octopus that was given a Mr Potatohead toy for Chrismas – and not only plays with it for extended periods, but gets aggressive if keepers try to remove it from his tank. (Thanks, PZ!) Awwww.

I see the level 3 paper had a question on indigobird evolution. This is quite a neat example of rapid sympatric evolution in an animal (& one that I use in my own teaching here at Waikato), so I thought I might flesh it out a bit for you here.
