To Larry and Brian's recent notes -- no SAGU in our backyard in Boise Foothills but have noticed the arrival of Rufous Hummingbirds over the last couple of weeks. After a summer of strictly Black-chinned, Rufous started arriving a couple weeks ago. One interesting observation is they seem to be much more territorial than the Black-chinned. A couple times I have noticed a Rufous guard its feeder for a half day or more, chasing away all other arrivals. During that period the sugar water consumption drops quite a bit. Then it moves on and consumption rates return to normal.
Overall I would say the summer period was more or less normal for us relative to hummingbird numbers. Right now we may be a bit above normal, but not hugely so.
