    • Gull killings

      The South Island colony of rare black-billed gulls has been decimated in an area they flocked to as a safe haven.  
       
      Hundreds of dead birds and their chicks have been discovered on the banks of a North Canterbury river.

      The carcasses of the protected native birds cover both sides of the Conway River.

      Rangers do not know for sure, but they believe they have been shot.

      "From the looks of it they've been killed by shotgun," says Craig Alexander, the biodiversity Doc ranger.

    • Day alone

      This morning, I discovered the music of British Sea Power and listened to the story of Bartholemew Roberts, whose death marked the end of the golden age of Caribbean piracy and opened the region up for slave trading.

      I bought boxes for seashells at the craft store, and the young woman with piercings gave me generous discounts.

      At the beach, the breakers were rushing in white and violent, sucking southward relentlessly. But the water was warm and I swam, if one can swim in chest-deep water, for an hour or so. Try as I might, I could not push out past the breakers.

      I headed to Sumner to watch Once at one of the last theatres still playing it. Out of the movie and still light, the patrons were a gas cloud of late middle-aged chatter boxes, and I jammed earphones in and headed down to the water.

      I wandered along the Esplanade, watching gulls break into shells, climbing for old time's sake onto Cave Rock. A few people gazed down off the side and I came to see that Peter Donnelly was just wrapping up one of his sand art works. I sat, hanging my legs over the edge of the void and he called up to me to check if he'd missed any bits. In the name of love, two sinuous forms on a field of waves strung between the rocks. Talking to him afterwards, he said this was his first work at Sumner. He normally works beneath the pier at New Brighton, but I said I thought this was a good place to work.

      It was quite beautiful up there. Yellow sun catching the tips of the waves. A dog with its head in an Elizabethan medical collar tottered along the beach in the distance.

      I rewarded my fortune with raspberry and chocolate torte and coffee at the cafe, chatting to the barista about music. He tried to convince me to have whipped cream, pointing out that nobody was around. Indeed.

    • the 5+ senses

      One of the great realisations of my early life was discovering that we had well more than five senses, and that (as a child) I seemed to be unable to convince anybody that this was the case. The facts of seven colours in the rainbow, four tastes and five senses are so well ingrained in common knowledge, yet all wrong. Aside from the commonly known exteroceptive senses that tell us about the world, there are the interoceptive senses that tell us about our bodies.

      Here are a few senses you may have forgotten:

      • balance (organs in the ear);
      • pain and temperature (skin);
      • internal pain (sensors throughout the body);
      • proprioception: your body's configuration in space (sensors within muscles);
      • bladder and bowel status updates (stretch sensors);
      • hunger and thirst (perhaps the hypothalamus).

      By the way, in the right circumstances it is possible to see the polarisation of light. The phenomenon of Haidinger's Brush is quite easy to see with a blue sky and a polarising filter.
