Latin capys 'a bird of prey' ( >> Etruscan capu), Germanic *habuka-z ( > English hawk), Slavic *kobuzъ \ *kobъzъ ( > Po. kobuz 'Falco subbuteo'), *kobьcь 'falcon, buzzard, sparrowhawk, etc.', Albanian gabë \ shkabë \ gabonjë 'griffon vulture, eagle, hawk' (opt. contm. shk- < shqipe \ shqiponjë)

Since capys is likely *kapu-s (imitation of Greek words with y), it could be from *kH2ap-u- 'grasping, seizing; raptor'. This would mean that the variation of voicing k, g(h) & p, b(h) would be the same as (https://www.academia.edu/175693920):

If *kH2ap- ‘take / seize / hold / have’, also ‘hold > enclose, cover, guard’ is the same as *gab- & *ghabh-:
*kap-ye- > L. capiō ‘seize / take’, Lt. kampt ‘seize / grasp’, G. káptō ‘gulp down’, Go. hafjan, OIc hefja ‘lift’
*gab- > Ar. kapem ‘bind’ (compare Latvian kampt ‘seize/grasp’)
*ghabh- > L. habeō ‘to have, hold; inhabit, etc.’, S. gábhasti- m. ‘hand/arm/fork ? / *forked > *lightning > shining RV / ray/sunbeam’

and maybe some other roots with mismatched k-b(h), etc. (origin & rec. often disputed). In *habuka-z & *kobuzъ \ *kobъzъ the *-(u)g^o- needs some explanation. The *u: > *u vs. *u > *ъ might show that Winter's Law in Balto-Slavic was optional (many exceptions; VD > V:D). I think the simplest idea is that *pug^- (L. pugnus 'fist') formed *kH2apu-pug^o- 'grasping fists/claws' with haplology. Since several of the verbs from *kH2ap- have *-eH1-, it could be that *kH2apH1u- existed here, with CH optionally voicing or aspirating (as *kH2apro-s 'male goat' > OI gabor, *pipH3- > S. pib- 'drink', etc.).
