Persistent calling of male from post-copulation perch. Audio slightly amplified in audacity and left channel removed; bird was barely audible on left channel and water noised was doubled so I converted recording to mono.
觀察細節
Probablamente 5. Una pareja cada uno con anillos. Here are some notes in English: first sighting of dipper today began with what looked like a catfight between two birds; they were on their backs in the water, essentially floating downstream while clawing at one another, flapping wings and apparently trying to hit one another with their feet. This went on for quite some time, and as they were moving downstream I was able to observe that both birds were banded. They were so tightly clasped together that I wondered at one point whether the bands on their legs had become somehow tangled or snagged together. However, all this fluttering and cock-fighting proved to be the pre-amble to a copulation. Mating also happened in the water, with the female nearly submerged. The copulation was typically swift, and the two birds flew a short distance upstream, with the bird I now took to be the male perching on a cleft log and beginning to sing. Recording is attached. Presumed male has two plastic bands on left leg, one white and above it one yellow, and a numbered metal band on the right leg. Presume female has green plastic band above white band on left leg and metal numbered band on right leg. See photos. Further photo of unbanded presumed immature bird. Further upstream almost in the village of Pinos de Genil was at least one more (I think two) unbanded adult bird.
