Roughly 50 million years ago, a lineage of birds known as Apodiformes (the birds with no feet) split apart, leading to today’s bird families of Swifts and Hummingbirds.  More recently, Rusty’s and Bob’s avian foci have also drifted apart − Rusty to Swifts and chimneys, and Bob to Hummingbirds and nectar flowers.  The two will present an in-depth review of these two fascinating bird families − their origin, diversity, physiology and behavior.

Recordings of the lecture presentations will be available to class participants  for a limited period of time.
