Scopes

Hi, visited the reserve today, super weather, flocks of lapwings and would you believe Gold finches amongst them however i also had my camers with me, its a bridge camera so does not have the the pulling power of a 300 to 400mm lens. Could someone please tell me if a spotting scope would help solve this problem and are they easy enough to use for photography. No birds of prey today, but Little Grebes beginning to nest.
