Heard a bird tonight which i have never heard before. It sung about 4 tweets in varying tones before ending with a high to low pitch, quite loud. I live in Blacktown, about 1 hour away from the coast in NSW. Also another one, with one (not loud) high pitch call followed by 3 or 4 notes the same length (very short, like a Fariy Wren's length of note) in descending order.
Also, 2nd one not heard at night time.
