birds in neighbourhood past two weeks, very athletic - diving, tumbliing, speedy and noisy, excited when displaying, interacting with each other or terrorizing nesting magpies. I have been unsure if they are Brown Falcons or Australian Hobbies, but today I have been able to view and identify as Brown Falcons, two birds, and have been able to see the dark markings on face - one larger brown ( female?) and smaller light morph (male?). larger bird may have brought food to other. Legs look to be grey, wing tips to tail.
