We all heard it as youngsters, “Don’t talk with your mouth full!” But we all do at moments, often with hilariously confusing results. So, the question is simple, can birds talk with their beaks full? And this time of the year with nesting and feeding of young birds, the answer is pretty easy to observe: yes, birds can certainly vocalize with their beaks full of food. The house wren that is pictured scolded me steadily as I passed in front of its house, even with a mouthful of grubs. And Robins are known to vocalize their full range of songs and calls with their beaks stuffed with nesting material or worms and grubs. Consider, birds have no lips or teeth to get involved in enunciating their sounds. Instead their notes come from complex vocal cord structures in the throat, able to emit their tonal communications with out action of the mouth or beak.
