No interactions present.
We've seen these here in Camberwell every year since 2008, after dusk and sometimes as many as half a dozen, over July and August. But not this year! apart from one possible sighting a couple of weeks ago. I assume the weather is responsible. I'm really sorry - I love seeing them.
Not sure - I didn't see any last year, several the year before and only one this year and quite late on. As migrants the weather might be a big factor in their presence.
