(x/2)+1 = 100  ⇒ x = 198 birds
$$\frac{{x}}{\mathrm{2}}+\mathrm{1}\:=\:\mathrm{100} \\ $$$$\Rightarrow\:{x}\:=\:\mathrm{198}\:\mathrm{birds} \\ $$

nobody said that the third bird was  also flying. there were totally 199  birds, that is true.  but what do you think can the third  bird greet the flying birds and make  a conversation with them if he  doesn′t fly himself?
