Status

BirdLife International estimates the stock of Braunbauchamazilie to 1000-2500 copies. The Braunbauchamazilie lives in a restricted area of ​​distribution that is threatened by overgrazing and fire clearance. The majority of the eastern slope of the Serranía San Lucas had been settled in 1996 and altered by agricultural use and cultivation of coca. Furthermore, their habitat through immigration, an oil pipeline and the mining industry is under threat. The Braunbauchamazilie is listed in Appendix II of CITES.
