Keep thinking I've sorted out the difference! Confused by someone who told me meadow pipits had orangey legs, then checked and a field guide said tree pipts had pinkish legs and meadows were brown.So have been watching (on gorsey heath land with small shrubby trees) what I thought were meadow pipits soaring with a 'sree, sree sree' sort of noise, then with song increasing in tempo, a downward rapid , almost 'dive bomb' flight to the ground.Very confused!
