But NOT for one group of birds –– TROGONS!...
The avian default of 3 forward and 1 back is #anisodactyl, i.e., "digits not the same". The 2X2 pattern is #zygodactyl, i.e. "digits yoked". BUT, *which toes* point where matters.
Toes are numbered, with #1 (our "big toe") in opposition for birds; they've lost #5 (our "pinkie toe")...

And their super-strong necks help them drum on trees without a headache!
👀 Spotted one? Let us know!

A roadrunner at the zoo. These birds are fast so I'm happy to have got some decent shots.

Avoiding spoilers, but here to report that in #Echo the #YellowBelliedSapsucker has #zygodactyl toes, gives #sapsucker calls, and does #sapsucker drumming cadence. Well done! No, it shouldn't be anywhere near #Choctaw lands during the growing season, but that's okay.
