165 and Counting...Earlier this week, Kimball Garrett, NHM Ornithology Collections Manager, spotted a not-so-common sight, a pair of Rufous Hummingbirds, Selasphorus rufus, in the Rose Garden. This hummingbird species is now number 165 on Kimball's Exposition Park Checklist. Over the last 28 years, Kimball has been keeping track of all the birds he sees in Exposition Park, even those that are just doing a fly-over!
Male Rufous Hummingbird An Annual MigrationMost of the year Rufous Hummingbirds cannot be found in our region, but in March and April they are often seen passing through. Every year this bird makes an over 3,000 mile migration from its overwintering grounds in Mexico to the Pacific Northwest. It is easily confused with one of our local hummingbirds, the Allen's Hummingbird, and so is often missed in species counts (maybe that's why it has only just made it onto Kimball's checklist). Males of both species have red-brown markings on their sides and tails, but only the Rufous Hummingbird also has them on its back. If you have a hummingbird feeder in your yard, keep your eyes open for this hummingbird stopping by to fuel up!
