My new 7D has video capabilty in 1080 HD which I´ve been tinkering with to get some bird songs and movies at the moment. I must say I´m very impressed by the acting, directing and soundtracks, although I should get my stereo microphone and hook that up to it. Anyway, here are some videos over the past few weeks of:
Flamingoes in la Laguna de Navaseca
A Great Reed Warbler in la Laguna de Navaseca
and some Choughs from yesterday at the Castillo de Caracuel
Watch them in 1080 HD for best video results.
