The odd couple

I had to go up town to collect another pile of train tickets and visit the office briefly. When I got back to the Shore I noticed these guys perched in their usual spot - of course, they could equally be girls, but I suspect they're a same-sex couple.  They just hang out together watching for tasty morsels and don't seem to go in for the usual gull histrionics. They could be the same two as were here last year.
