My critique - try to note the scene lengths in NatGeo bird or wildlife features, these are mostly very short, 2 - 3 sec or at most about 5 sec. Such fast-paced editing is intended keep the viewer's interest at a high level. If you have more footage of the bird, say from different angles or magnification, you can insert these in 5 sec cuts.
Re posting from flickr, try to post the embed code here and let me see how we can do it. BTW, I modified your post to use the following embed code and do away with the box ad.
