    Suppose there are x birds on a tree then the total number of trees in the wood is also x.Therefore total number of birds in the wood=x^2.Therefore number of birds should be a perfect square and there is only one perfect square between 2000 and 2100 ie.2025 which is square of 45
    Therefore there are 45 trees in the wood
