I'm reading an interesting book at the moment and it prompted a
question.
i wondered just how many birds there are in say Australia or on
planet earth. I'm talking total numbers rather than species. i
googled and read a couple of interesting pieces on the subject
including some research from Gaston and Blackburn which suggests
there are between 200 and 400 billion birds on earth! Wow! Another
study estimated 100 billion plus birds on earth. In comparison there
are around 6.6 billion people on earth, so our avian friends well and
truly outnumber us.
i wondered if there was any data/estimates on the total number of
birds in Australia?
Also I pondered on some of our more common species - say the Magpie
which has a very wide distribution across the nation - I wondered
just how many it may be estimated are in Australia?
Or perhaps what are our most abundant species in terms of total numbers.
Thought it might open up some interesting discussion, estimates ( or
guesstimates! ) data or research info that may have been done.
