The survey was separated into two types : general behavior (eating, moving, cleaning themselves and sleeping) and courtship behavior (sleeping on their nests, building their nests, crowing, shaking their heads, singing, and breeding). The results found out that we could not certain that there were any relationship between the GSP and Zebra Doves’ behavior or not, because the same Zebra Doves could not be monitored (the Zebra Doves with good qualities were sold). Thus, the third party was discussed with the bird behavior’s and bird breeder’s experts. In conclusion, the statistical methods were used for consideration by monitoring more Zebra doves from each farm and calculating in percentage. These methods had been approved on the meeting with the Subcommittee and the trilateral Commission already. Zebra Doves behavior were observed monthly at 5 farms during January to December 2017. The results had been summarized below : 1. S.P.K Farm (3 km from the GSP) - 80 breeding cages - More than 300 Zebra doves - More than 50 breeding pairs - 466 eggs - 168 Zebra doves with satisfied sound qualities - A few Zebra doves were sick (but not due to the GSP activities)
