In El Paso, Texas

I am in El Paso, Texas, where my host has two hummingbird feeders stocked with sugar-water. They're hanging right outside the window as I post this. There are half-a-dozen hummingbirds who frequent these feeding-stations. Sugar-water must be the crack cocaine of hummingbird life, because these half-ounce bundles of buzzing hyperactivity are stunningly aggressive. There's plenty of liquid sugar in there for everybody, but these little buzzbombs are banging each other's tiny jewel-like carcasses as if they were sumo wrestlers.
