Result from GLMM and LMM to evaluate variation in breeding performance (laying date, clutch size, productivity, and breeding success) of American kestrels in relation to rainfall, temperature and the different land uses in the buffer of 500 m around nest boxes in the center of Argentina from 2012, and 2014 to 2016.
