I don't know what the hell is going on here, but i don't like it one little bit.

I often see the odd tu fong cruising around my place but today was out of control. Repeatedly buzzed while i was making the furniture and one even landed momentarily on my shoulder. I wasn't game to keep working and went back to the house to discover a bunch of them congregating on the shade cloth i've strung up just metres from the front door. They seem to be doing something, they're definitely communicating, but i don't know what. I'm concerned that they've either got a nest nearby or are planning on building one.
