They perch upright at mid-heights on vines or other exposed perches, in this case a hydro power line, and sallies out for flying insects, especially butterflies, dragonflies, and wasps. They have a very long, slender black bill (like a giant hummingbird). The throat is white on the male and buffy on female.
Next up will be images from our Cuban holiday back in April.
Thanks for reading.
