## Abstract Gonadotropin‐releasing hormone‐I (GnRH‐I) cells are localized primarily to the septopreoptic area (POA) and are responsible for regulating gonadotropin release from the anterior pituitary. Some songbird species exhibit dramatic seasonal variation in the number of detectable GnRH‐I immun
