Basically feed on seeds, they crack the seed using their beaks and tongue to manipulate the seed and take the “husk” off, parrot type birds do the same thing. Softbill birds do not do that. They may “swallow “or break it open by holding in their feet and pecking with their beaks, but they don’t process the seed with their beaks/tongue first. Softbills whether insectivorous, frugivorous, or omnivorous, basically eat items with little preparation.
