Power lines are among the ugliest by-products of our electronic age but the ‘cut’ also provides wonderful habitat for birds, particularly flycatchers and warblers. I’m up on Goldstream Heights, picking my way over the rocks. Before long, I’m too focussed on the calls of birds to be aware of the huge metal towers looming nearby. A Song Sparrow chips a warning – I’m the topic certainly. As I stop to take in the view of the Olympics across the Strait of Georgia in Washington state, four Band-tailed Pigeons flash by overhead, streamlined, swift flyers like all pigeons. Below them, a tropically-coloured Western Tanager flashes yellow and red, landing briefly on a distant treetop. My mind is on flying birds. Suddenly a MacGillvary’s Warbler startles me with a blast of song. He pops into view, giving me some great looks. Lovely. Even with the towers and high-voltage lines, there are worse places to be than here on a mild May morning.
