Human development and now especially climate change is causing many species to shift their ranges poleward. Around here, the most notable examples are Anna's Hummingbird, Calif Scrub-Jay, Black Phoebe, Lesser Goldfinch, and some others. At the same time, there are still cold waves (especially the last few winters!).

It is possible that species/individuals that are up here now from the warmer south may have issues. They will all likely gorge whenever they can find some foodstuffs and when not eating they will look for a well protected place to sleep.<br>
