I've been harassed by Swifts, White-Throated Swifts in fact, while flying at the Toadstool Hoodoos. Swifts are the fastest birds in their group and among the fastest birds on the planet so trying to out-fly them is quite simply impossible -- the Inspire 2 wouldn't stand a chance so the P4P isn't even in the running. As you can see in my video they make frequent strafing runs at the P4P but stay far enough away to avoid contact. They are petty amazing birds for sure as they are purpose built for one thing -- speed!

Great video, incredible scenery. Aggressive birds.
