Carl’s comment probably comes from this extract:
“The noisy miner, a native with a distinctive, high-pitched call also known as a ‘squeaker’, and the koel, a large cuckoo bird, are the most common troublemakers.
The problem is that they are nocturnal birds. I personally like their sound, but some people don’t,” Davis said.”
It only appears to include Noisy Miners as the nocturnal birds (they aren’t) only because the sentence structure is confusing. The implication is that it says Koels are. Which is certainly correct in terms of their calling. What Carl has interpreted arises from the annoying journalistic habit of joining sentences when they shouldn’t and making one sentence paragraphs and thus losing the right connections of ideas.
