Hummer Doings are Different

One of the most striking things about the current hummingbird season is the surprising amity between birds.  I am used to one particular hummingbird (usually the female!) driving off other hummingbirds from one or more feeders.  But to my surprise I am seeing none of this and in fact have seen male and female working the same feeders with no airflights at all.  These squabbles may be occurring but I do not see them.  And believe me, I have seen many of them before.  One possibility for the change is the huge increase in nectar bearing plants on the property:  maybe there is less stress over resources?  I'll have to see if this continues!
