The Arizona-Sonora Desert Museum presents this update on the Museum's Migratory Pollinators Program, which focuses primarily on part of the nectar corridor extending from south-central Mexico to central Arizona. The report, which covers program-related research, is nicely presented and a pleasure to read. Anyone with even a passing interest in plant-pollinator interactions should find this site appealing. Museum researchers examined the migratory routes of lesser long-nosed bats, rufous hummingbirds, Western white-winged doves, and monarch butterflies. Each species exhibits extraordinary migratory behavior now considered "endangered natural phenomena" due to poor ecological conditions along their 2000 to 6000 kilometer flyways. The report also includes a useful glossary and an overview of the Museum's education outreach program.
