To make sure my animated bird would move as accurately as a real bird, I did a lot of research into how birds move. I mainly looked at videos, since they can give me more information than images could, particularly looking for slow motion videos so I could see all the subtle movements that I might not have seen if I just looked at a normal speed video.
Here are some of the videos I used as research and some comments about them:
The above video of a starling taking flight in slow motion proved very useful to my animation and was the main inspiration for the start of the video. Birds move very quickly when they are taking off, so getting a slow motion video of this quality really helped me understand how a bird moves when going from a standing position to flying. All the subtle movements that the bird makes, from crouching down and springing up to how its body, legs and wings stretch at the moment of take off are captured in such high quality that I feel I was able to recreate them very well in 3D. The end of the video also includes the first few seconds of flight which helped me out when animating the first wing movements after take off.
While the starling video helped me start my animation a lot, the above video was also very useful to me because it captured a bird doing the same movement from the side instead of the back. Something I had learnt through animating in the past is that recreating a movement from just one angle can lead to the animation looking weird from other angles.
Although the above video didn’t really factor into my animation because the birds take off in a different way than I wanted my bird to, it still served as good reference material because it includes birds flying around in lots of different directions which helped me to understand how birds use their wings to move about in the air.
The above two videos served as good reference material for the first few seconds after the bird takes off. Through my research, I saw that there is a great difference between how a bird moves when it just takes off compared with how it moves when it is already flying in the air. These videos helped me understand how the bird in my animation would need to flap its wings a lot stronger right after take off to get enough thrust to lift it into the air.
After getting enough research of birds taking off, I moved on to researching birds flying through the air. The above video shows a flight cycle of a pigeon from the front, which I used as reference material when it came to the bird moving its wings while flying. All of the other reference videos I found of birds flying were shot from different angles, so this video helped me see what my animation should look like from the front.
Around half way in my animation I wanted my bird to glide for a bit after flapping to build up speed, so I also researched this and found the above video. When I first had the idea of having my bird glide I thought that, aside from having the bird continue to move forward, it would remain relatively still since it would no longer be flapping its wings but by doing this research I discovered that this was wrong and would have resulted in a very wooden looking animation. By watching this video, I saw that when gliding, birds still sway from side to side on the wind currents, their legs still move about and they do occasionally flap their wings to lift themselves upwards. I’m very glad I did research into what birds look like when they are gliding, because if I just animated on how I thought they glide my animation wouldn’t have looked good at all.
After having the bird glide for a bit, I decided that it would be good to have the bird turn while flying and change direction since, more often than not, birds don’t fly in perfectly straight lines. Like with gliding, I felt I had a good idea of how a bird rotates while turning but I did some research into it to make sure I didn’t miss out any subtle or secondary movements. Through watching the above two videos, I learned that birds often keep their wings straight and glide while turning, but start flapping their wings while finishing the turn in order to push themselves forward. I also saw that birds tend to keep their heads parallel with the ground while turning instead of rotating it with the rest of their body while turning. Both of these movements I kept in mind and incorporated into my animation.
My animation ends with the bird landing on a platform and eating some bird food that is scattered there, so research into how a bird lands from flight was vital to my project. The above video shows a bird flying around for a bit before landing on top of a lamp post and was the main reference footage that I used for my landing animation. This video helped me to see that, before coming to a stop, a bird will flap its wings to lift slow itself down and lift itself upwards to land. I also saw that birds stretch their legs out quite far to reach and touch the ground before using their wings to push themselves forward and on to the ground.
However, it is important to know that since there are many different types of birds, they all move about in different ways. The above video shows a bird landing in a completely different way to the previous video. Instead of landing from above, this bird flies up from below to land, and it also retracts its wings before it even touches the ground, only flapping once to slow itself down. When it came to finding contrasting research videos like these two landing videos, I thought about what type of movement I would like in my animation to know which to use as reference. In the landing case, I decided on using the previous video as I felt it better suited all of the other types of movement I decided on using earlier.
While these videos made up the bulk of the reference videos I used for my animation, I also found the following videos while doing my research and felt that they were also good examples of bird movement that I could perhaps use in future if I revisit this animation or do another bird animation.
