The length of the day triggers the seasonal responses of many animals. This is also the case for parrots. I have noted this for caiques. When I provide my breeders with light for 13 to 14 hours per day they usually go to nest and will breed all year round. If I keep their exposure to light at 12 or less they stop breeding. This has been better documented for Amazons (Millam, 1999).
