觀察細節
Count based on presence of apparent pairs, perching and, in several instances, investigating or visiting bank cavities, in 4 near-vertical banks along the stream (2 above and 2 below the diversion dam). "P" breeding code based on frequent sightings of two birds together, and observation (several times) of one bird investigating bank cavities or perching at the entrance to one while a second bird perched nearby. During ca 10 minutes of observation of a bank frequented by an apparent pair, between the cross-fence and the diversion dam, I did not see either bird enter the hole or carry nesting material.
