Greg et al.:

Interestingly, I had a Laughing Gull on the Potomac River near Gunston Cove yesterday with the same wing pattern. Maybe this is just some particular stage in the molt cycle where some wing coverts have molted out exposing the underlying primary and secondary feathers? It sure had a nice triangular shape to it!

Good Birding!

Sub-adult Laughing Gull with a wing pattern slightly resembling a Sabine's Gull, 
but the pattern was certainly unique for a Laughing Gull--the
secondaries were almost entirely white and the innermost primaries were
widely edged with white--is this a partially leucistic Laughing Gull?
