I have been trying to trying to replicate this logo for my team (not to mention in LaTeX ofcourse:-)):

So where I am now:

end{document}

which gives me:

Having said that, with respect to the original figure, the challenges that I face are three-fold:

1. I am not able to match the blue color between the gears and the first white circle. [worked as per Phelype Oleinik suggestion]

2. I am not able to replicate the barrel shape in the teeth region of my figure (compared to original).




3. Finally, ofcourse, I used a lot of helps from other answers that are linked to this question (especially, @Gonzalo's Bézier trick). But still I am not able to get the smooth finishing of my Falcon.

All helps and suggestions are appreciated. Nevertheless, any optimisations of my code is more than welcome.

I was always scared by falcons. They hunt us! (With to[in=...,out=...] one can do a lot of things, and if one in and the next out differ by 180, there is no kink.)

UPDATE: Implemented Max' suggestions for the teeth of the gear and also changed the teeth of the falcon. (Those who want to object that falcons do not have teeth: here's a counter example. ;-)

Addendum: Original beak and removed things that are not used.
