In a garden near the McKenzie River in Oregon’s Cascade Mountains, a downpour pummels the landscape. Imagine a Rufous Hummingbird, like this male, out and about, extracting nectar, searching for gnats and aphids. A hummingbird's stamina against the heavy rain is marvelous. Consider this: its body is nine and a half centimeters long; the average raindrop is about four millimeters. That would be like a person 5'8" being pounded by a torrent of raindrops each three inches across. Incredible!

A Rufous in the Rain
By Chris Peterson
This is BirdNote!
[Heavy rain – and flowing river]
In a garden near where the McKenzie River rushes out of Oregon’s Cascade Mountains, a downpour pummels crimson-flowered currants, salmonberries, red columbine and native rhododendrons.
Evening draws near, and I’ve taken shelter from the deluge. To my surprise, a female Rufous Hummingbird is still out and about, extracting nectar, searching for gnats and aphids. [Bring in wing whir of Rufous Hummingbird] No doubt, she’s feeding two nestlings that await her return to their tiny nest hidden in a Sitka Spruce or Douglas fir. She’ll feed them every half hour for fifteen to twenty days. As night comes on, the feedings must increase. [Wing whir of Rufous Hummingbird + in the rain]
Rufous Hummingbirds migrate mostly from Mexico, arriving in the Pacific Northwest and Alaska, as early as March. By July, as higher elevations warm, they’ll turn south again, to follow a “floral highway” along the Rockies. [Bring in wing whir of Rufous Hummingbird]. This little bird will need to build her own energy reserves for this trip, soon. [Rufous Hummingbird]
I marvel at her stamina against the heavy rain. Think about it – her body is nine and a half centimeters long; the average raindrop is about four millimeters. That would be like a person five foot eight being pounded by a torrent of raindrops each three inches across.
