I apologize for the quality of this photo (the light wasn't great - in the shade), but couldn't resist trying to get a shot of this one (centre) doing all kinds of aerobic moves (even hanging upside down - but couldn't get a shot) in order to try and get too some insects on the branches of a small tree.

All I can say is that - yes it was successful - and they really must have tasted real good to it for it to do it :-)
