Window Open, Listening for Hummingbirds

The feeder has been up for three days, but no visitors yet. I thought perhaps they don't come to this neighborhood, but N. says her mother-in-law lives four blocks from here and they come to her feeders. Maybe I should hang up the second feeder, too, so it looks like a hummingbird cafeteria.

The madrone are blooming in the empty lot across the street, and what looks like a crabapple disguised as a sprawling shrub. Rhodendrons here and there around town. Landlady hasn't finished the landscaping yet; perhaps I'll ask her for some hummingbird plants. (Searching the web. Searching, searching...) I wonder if cardinal flowers grow here, or red beebalm.
