Answer:
Difference in their beak size, colour of their feather and body size.

The genetic variation that occurs in the three different species of bird is the difference in their beak size, colour of their feather and body size. The difference of beak size occurs due to difference in their food selection that is available to the birds. Some birds of the population feed on small food particles having small beak size whereas other have large beak size due to preference of large food materials. Some birds have colour like their surrounding that helps them to hide from their predators. Some birds specie have large body size due to availability of more food or due to genetics.

Hip Inferior Glide is used to improve hip flexion. The technique is performed in supine with the hip flexed to 90°.
This technique can be used for decreasing muscle spasm or pain, and is also useful to increase accessory joint movement for flexion and abduction movements.
By performing the therapy the clinician’s hands can be clasped at the superior proximal femur or a mobilization strap can be used to enhance grip and reduce sliding on subject's skin. The clinician can simply lean back to impart an inferior force to the femur with a counterforce of the shoulder on the distal femur.
