This morning at the mouth of Carpinteria Creek I saw a weird-looking gull that I think is probably a leucistic immature Heermann's Gull. Photos are in the following eBird list:

I'm curious if others have opinions about the bird, or past experience with similar birds.

Some googling turned up some interesting photos by Oscar Johnson from 2008 of a leucistic adult Heermann's Gull with similar light-brown coloration. See:

So it seems possible that if the immature I saw today makes it to adulthood it could end up looking like that.
