Low-poly pigeon

Low poly rigged pigeon model created in Blender plus tons of STLs in different poses.
If you are confident in your blender skills, you can open the .blend file and pose the model to your heart's content! Otherwise, there's a good selection of STLs you can use.

Two of the “flying” pose models also have a small loop on their back so that you can hang them from a string. Just be aware that I haven't tested their balance yet, so I'm not sure if they'll hang nicely or not.

You may have to scale and rotate the model to make it printable on your printer. Many of the poses print best laying on their back so that the legs/feet stick straight up. Make sure you have very good support settings, as these models absolutely need them!
