The San Francisco Bay is the largest estuary on the Pacific Coast, making it an ideal refuge for a variety of winged creatures including shorebirds, raptors, and songbirds.
Every fall more than 250 species of migratory birds visit the region, so whether you’re on the sandy shores of Ocean Beach, or hiking the steep slopes of Mt. Diablo, or just sitting on your backyard patio, you’re already on the perfect viewing platform.
In order for most people who read this question to have a meaningful answer, they'd have to a) work with a lot of them, and b) know they're working with a lot of them.
I'm sure the demographics will show that they skew more young, more educated, more wealthy, more single, and more asian than those currently in the bay. An amazing number (amazing to me at least) have a "deal" on housing by relatives or friends letting them couchsurf or use the spare room. Most (not all) come from larger metro areas (as in larger than SF/SJ).
If so, I feel even more lucky to be outside that culture than I ever have before.
I left the bay area midway through 2017, but up until that point, I saw those same patterns in play as usual.
