Yes. I think was done a few years ago. You need a bird model with flapping wing animation. Use the AIAircraft to provide the FDM.

We already have some birds - that are used by glider pilots to find thermals. If you are looking for something a little more sophisticated, you can use the AI traffic system, which is fully scriptable using Nasal - FlightGear really doesn't care what type of 3D model you are using, so it doesn't matter if it's a tanker, fox2 missile, f14b or the 3D model of a bird:

Hooray wrote:Just to prove my point: It really doesn't take any longer than say 2-3 minutes to open the tanker.nas script, change the model file name to point to the 3D model of a bird, what you end up with is a "funny bird" flying at 330+ kts ground speed at 17000 ft AMSL (I took the first freely available bird model that I could find...):

As a next step, one could change the heuristics that move the bird (assuming that you don't want it to keep flying refueling patterns...), making it search actual thermals (local weather) would also not seem too complicated - it would just involve calls into the local weather code.

Probably, you'll want to add some collision detection code then.
Once this is working, you may want to animate the whole thing and probably change its size, too.

Like I said, it's all perfectly possible with the tanker.nas script.

Also, please do let me know if you need help creating "effect contrails" out of feathers and blood, okay :lol:

VicMar did some animated seagull submodels to some of his lighthouses about a year ago.

Thanks for the mention Johan.

If you want to see some in action, start a flight at EGKA. There are some to the left of the default runway (beside where your aircraft spawns), and some flying around above the EGKA Terminal.

Cheers,
Vic
