Arkive.org – a whopping great video archive
This site is a great resource for short clips of hundreds of different species in the wild. Thanks to Philips78 from the TES Boards for the link. They are streamed videos – WMV, RealVideo or Qucktime – and you can download each one via a button below the video. Go and have a look – you could spend hours and all your bandwidth, so get comfortable.
