When I was down at Kiholo recently, I saw this wandering tattler at the shoreline, hunting around for a bite to eat. I followed it for a while, from a distance.
It snagged a katydid at one point (second photo), but I didn’t see it catch anything else. It spent a fair amount of time around one particular rock (third photo), which caused a good deal of consternation for the a’ama crab that was there. I think the crab was a bit too big to fall into the category of prey for this particular bird.
