Starting in early July, I make it a point to visit the Basket Island causeway a couple of times per week. This southern Maine spot is a premier location for observing summer shorebirds, gulls, and terns. I often bird the causeway 1-2 hours after low tide, when the rising waters concentrate a variety of birds onto shrinking sandbars.
During a visit on July 2nd, I'd already photographed my first Whimbrel of the year, and was watching a small group of Roseate Terns, when I noticed a much larger tern alone in the distance. Caspian? No, this bird lacked a full black cap, and had an orange, not red bill. It'd been almost two full years since my first and only sighting of a Royal Tern at this same location, but finally I was looking at another.
Unfortunately, almost as soon as I noticed the tern, some beach-goers approached the bird from the other direction. Before they pushed the bird, I moved quickly to capture the photos you see here. Moments later, the walkers got too close and the Royal Tern took flight, flying past me and out over the water where I lost him/her in the bright morning sun.
I suspect this won't be my last Royal Tern sighting. I just hope the next one doesn't take another two years. You can bet I'll be visiting the Basket Island causeway a few more times this summer to increase my odds.
