A bird sings using its syrinx, at the basis of the trachea, unlike our speech organ, the larynx, which sits at the top of the trachea.

Jackdaw (Coloeus monedula), Irish: Cág, French: Choucas des tours
Chough (Pyrrhocorax pyrrhocorax), Irish: Caǵ Cosdhearg, French: Crave à bec rouge

Researchers found that the ravens performed worse than the apes in only one category: spatial intelligence, where the tests involved remembering where treats were hidden. This was unexpected. The authors believe that the ravens may have been reluctant to show the testers where the food was hidden because the humans might take it for themselves. We have to consider that the bird may be trying to outsmart and trick us.
