Within the world of birds and nesting there are those species that respond to available resources prior to nest initiation. Rainfall, growth of foodstuffs, and so on. While by and large birds nest in the spring there species that are much more complex than that.

Thanks and good birding, Joshua Glant

I think it's 'recrudescence', spelling is probably off. :)

Thanks for bringing this up! I was going to mention it myself, but I didn't want to appear ignorant by linking two phenomena that weren't related... :)
I've been hearing Robins, a Varied Thrush and even a Townsend's Warbler sing in the past week! I believe I read somewhere that there is a specific name for this photoperiod-related behavior, but I haven't found it yet.
I don't believe that the Anna's Hummingbirds quite fit into this phenomenon (they're territorial throughout the season), but I could be wrong. Who says hummingbirds are exempt, anyways?

"False spring" near the fall equinox elicits a mirror image pulse of spring breeding behavior among many bird species. Same length of day/night as spring.
Listen for courtship calls, copulation, pairing up for awhile. Probably most easily viewed in starling behavior.
