This increase levels of estrogen and progesterone would cause a negative feedback to the hypothalamus and the pituitary, which would result in the decline of the FSH and LH.

Zoology is the study of animals, generally speaking, and since birds are animals, the study of these fall into the field zoology. The study of birds though, is called ornithology.
