Burleigh Heads Tag

I could only find one headland at Burleigh Heads,....soooooooo why do "they" add the "s". Perhaps one headland was washed away, or perhaps the plural just sounds better? The one and only Burleigh headland is rather small, so maybe "being" pluralised makes it feel bigger? OR.......perhaps the late Eric Morcombe was "wise" when he uttered,
"There's no answer to that, is there"
