This is on my list of birds to find, as it is supposed to be exist in this area,but I've never identified one. Their call (see Vogelwarte link) is a rapid sequence of whistles, and definitely distinct from that of the red kites. Visually they are harder to tell apart, but if you look closely, it should be clear: the black kite has less of a V in its tail and no big white patch at the wingtips. birdguides.com has a guide to distinguishing black and red kites, and says black are much rarer, but that is not true in Switzerland - Vogelwarte.ch says Switzerland has 2800–3500 red kites and 2000-3000 black kites.
Tenatively identified one flying high over Lake Lugano at San Salvatore in Ticino.
Often near water.
Vokalisierung: A piercing, first ascending then descending long "piuuu". Starting as a clear tone then gradually taking on a vibrating character that differs from Red Kite. Also a sharp "kieee -ki- ki-ki". More vocal than Red Kite. [Link]
