Here's an interesting juvenile American Herring Gull with what looks like a series of pearls all across the subterminal tips to the primaries and greater primary coverts:

Juvenile American Herring Gull. Chicago, IL. 15 August 2012. |
Juvenile American Herring Gulls have been out and about for a couple of weeks now on the Chicago lakefront. This species is our only other summering gull, found in much smaller numbers than Ring-billeds.
A quite beautiful effect as well as unique.
