The baby bird's beak sign is an antenatal ultrasound appearance formed by the pulmonary artery abnormally arising from the left ventricle in fetuses with transposition of the great arteries 1-3.
In these cases, the pulmonary artery bifurcation and abnormal outflow tracts mimic the head of a baby bird with an open beak 1-3.
