Fire type fletchling, ground type fearow, hoothoot and noctowl can be psychics, swablu can be water I guess, staraptor and braviary can both be fighting types. I dunno about Farfetch'd but I feel like it could be grass type since it's already got a fighting type regional.
That would mostly leave you with the original Pidgeot line, Dodrio, Swellow, Unfezant, and Toucannon.
