观察细节
Seen flying over open water in between boat ramps. Quick and sharp wing beats in flight. Would also dive towards water and coast over it (but did not see dive into water). Small, orange-bill with black tip (clear orange, not orangeish-red). Primaries/secondaries very white/silvery and didn't not notice significant darkening on primary edges (as described in Sibley for Common Tern). Got matching sound is via Nerlin and got basic ID photos when perched on buoy. Both Sibley and Audubon's Society Encyclopedia of North American birds both noted Forster's is much more common inland than Common Tern.
