    • 2009 March 25, Michael McCarthy, “Triumph of the bumbarrel (aka the long-tailed tit)”, in The Independent[1]:
      One of Britain's most charming small birds, once known as the bumbarrel, has entered the garden birdwatch top 10 for the first time. The tiny long-tailed tit is so small – the tail is longer than the body – that it is very vulnerable to cold weather.
    • 2012 March 12, Katie Fuller, “This weekend... spot a bumbarrel”, in RSPB.org[2]:
      ‘Bumbarrel’ is an old name for the long-tailed tit, everyone's favourite garden bird. And the reason they're called that is for the shape of their nest.
