I caught one today at Victoria University of Wellington. It was flying above the Waka Gates pokestop watching a fight. Surprisingly easy to catch (2 ultra balls), given that we fired ten times this many at a Dragonite recently and never even hit it.
I’ve only seen 1 Dragonite in the wild, it was exceptionally hard to throw the balls even far enough to reach it’s feet. I’ve since put a tip on how to throw Poke balls further, but I know that a few months ago Niantic did make flying Pokemon easier to catch. I’ve not enountered a Dragonite in the wild since 🙁
