The Biggest Eagle In The World

What-to make a conclusion or an assumption.
So What-I learnt how to use a T Chart . I firstly wrote down a inference, then I'd write because..... (from the evidence from the text).
Now What-I think I should write down more ideas and only have to read the book once.

Here are a couple of my thoughts.......

-I think that the Haast's Eagle was the biggest eagle in the world because .... It weighed 13 kilograms , a wingspan of 2 metres and powerfully muscled legs and feet.

-I think the Moa was the biggest flightless bird in the world because ......... It weighed almost 200 kilograms.And the Maoris wanted it for its large amount of meat,bones and feathers.
