This is a 3ds Max sample scene showing how to a custom object can be used with particles to simulate a flock of birds.

A note from the author is included in this scene:

This is an example of a technique for creating flocks of birds similar to what we did on "The Day After Tomorrow." Instead of creating flocks by using complex flocking algorithms, we created a custom object that could be filled with particles. These particles would then use instanced geometry of animated birds. The particles stick to the surface of the custom objects and move with it as it moves. Noise was used to add some randomness to their motion. A few parameters control the shape of the flock. With this technique you can quickly create a flock of birds.
