Bird-eating fish


in France
It was a huge surprise to hear
of a fish catching and eating a bird


  • it’s usually the other way round!
    The wels catfish tends to feed on
    invertebrates and smaller fish,
    but, in one place in Albi, in the
    south of France, it has developed
    a taste for pigeon.
    Next to a 1,000-year-old bridge in
    this city is a ‘No fishing’ sign. For
    this reason, catfish are found in
    enormous numbers, and they grow
    up to 2.4 metres in length. By the
    end of summer, there are not many
    fish left for them to eat. So, in the
    last 15 years, some of them have
    turned their attention to catching
    pigeons instead.
    As the pigeons bathe, oil from
    their feathers starts to flow
    downstream, and the catfish detect
    the smell. It’s an eerie sight seeing
    this river monster swim towards
    a group of birds splashing in the
    shallows. When a fish strikes, you
    can hear a loud sucking noise –
    rather like something disappearing
    up the vacuum cleaner – as it slurps
    the bird into its mouth.
