HI all- concern is increasing now about just how small the bittern population is in Australia. recent surveys suggest a minimum of 200 birds and for the areas monitored an upper population estimate of 600 birds. The significance of the NZ population is increasing.
Check out the following link which gives an indication of the recent decline of bittern numbers in Australia

Note- data suggest that numbers have declined since this survey was under taken, over the last two years.
