Our work declares the first endeavor is the elemental analysis using scanning electron microscopy\u2010energy dispersive X\u2010ray (SEM\u2013EDX) to show the migration effect on their eye. The intra\u2010ocular quadrilateral trapezoid black pigmented plicated type pecten oculi were observed on the postero\u2010inferior wall of the eyeball with craniocaudal and posterio\u2010anterior directions along the fetal fissure. The pecten oculi consist of three parts: the basal, body, and apical. The basal part originated behind the optic nerve, forming the slightly elevated border, while the apical part was directed toward the ciliary body. There are 10\u201311 pleats with interpleat space. The coiled surface refers to numerous capillary vessels. The smooth head of each pleat was kidney\u2010like, strongly attached to a bridge. The vitreopecteneal limiting membrane separated the pecten oculi from the vitreous body. There are numerous melanosomes and little hyalocytes on the pecteneal pleat's outer surfaces. The thick basal part of each pleat had numerous thick longitudinal microfolds that refer to the numerous blood capillaries attached to the retina as supporting roots. SEM\/EDX elemental analysis revealed that carbon is the highest element (half), while oxygen represents about one\u2010third. In the meantime, the lowest element is the phosphate at the apical part, while the lowest element in the rest is the sulfate. Finally, the pecten oculi are thought to be a reflection of the avian lifestyle and ecological adaptations.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Highlights<\/jats:title>\n                    <jats:p>\n                      <jats:list list-type=\"bullet\">\n                        <jats:list-item>\n                          <jats:p>Our work is the first description of the elemental analysis using SEM\u2013EDX to show the migration effect on their eye.<\/jats:p>\n                        <\/jats:list-item>\n                        <jats:list-item>\n                          <jats:p>The quadrilateral trapezoid black pigmented plicated type pecten oculi were observed on the postero\u2010inferior wall of the eyeball with cranio\u2010caudal and posterio\u2010anterior directions along the fetal fissure.
