Jonathan's comments also apply here on the West coast. We have two species, one migratory, one not. I have never noticed either on lilies, but I don't have many lilies, and do grow lots of fuchsias, and other hummer favourites. In mid-winter, the hummingbirds feed on Grevillea victoriae, Arbutus unedo, Mahonia. There are also a lot of bright yellow Jasminum nudiflorum flowers all winter, very close to one of the feeders, but I have never seen a hummer on them. No nectar, I guess.
