While looking through my father-in-law’s copy of Peterson Field Guide to Birds of Western North America, I found the answer to a quest of mine.
This bird, which I photographed in April, is called a Black-crowned Night Heron. While he did appear more blue to me, I do believe my mystery has been solved.
I initially noticed him on the far-side of a pond nearby our apartment, while I was photographing some goslings and their parents at sunset. I saw him fly toward the side of the pond I was on, and as I went closer, it began to rain. I crept up and managed to get a great photo of him/her before it began to rain harder. If you look closely, it even has a bit of food left in its beak.
