No problem with your connection. These videos are intended to be slow motion.
"Tsubame" is the Japanese word for "Swallow". It's the baseball season and I heard that the "Swallows" were pretty famous so I went out for a look. They sure look cute and provide good action but I'm sceptical about their baseball skills.
My first attempts at high-speed digiscoping using a Nikon p300 attached to a Nikon ED50 fieldscope. The first four videos are in slow-motion but the last is in real-time and shows the actual speed of parental swallow feeding.
Barn Swallows at Fukushimagata, Niigata, yesterday.
The original for this last one is in full HD.
