It's hard to say about returning Summer Tanagers at Lake Los Carneros, because we've had so many here over the years, including multiple birds in some winters. We have a similar situation with Tropical Kingbird at certain spots, like Campus Lagoon, the bird refuge, and NCOS.
The best example of this conundrum I can think of is Paul Rosso's White-throated Sparrows on the south side of Lompoc. For a while, it seemed like he must've had a single bird returning year after year. But once he passed the 20 year mark of having a wintering White-throated, and then had as many as three in a winter, it was clear we would never know how many years any one bird came back. I believe he eventually reached 25 consecutive years.
