An adult male of Red-footed Falcon Falco vespertinus was observed and photographed on a 8mm cine film at Nagaoka, Niigata Prefecture, on 27 May 1979. During my observation the bird was perching on an electric wire and appeared to be on the lookout of his preys. I once saw it caught a frog in the paddy fields nearby. It was a rainy day and the bird stayed in the same place from 16:00 to 17:30 hrs, but I did not see it again next day. This was the first record of the species for Japan. The details of my observation were as follows: upper-parts, chin, throat and breast all dark slate-grey; lower belly, thighs and under tail-coverts rufous; cere bright yellow; legs red; under wing-coverts silver-grey.
