The annual nest numbers have been estimated using maximumlikelihood and are therefore asymptotically normally-distributed [11]. Growth parameters are adjusted also by the maximum likelihood method. Standard deviation was modelled using two additive components: error on annual estimation and an adjusted component describing inter annual fluctuation. Error on r and N2006 parameters are estimated by the inverse of Fisher matrix calculated at maximum of likelihood [1]. The instantaneous growth rate of the exponential growth model has been fitted with maximum likelihood method firstly at the Central African scale and then at a country scale. Statistical analyses have been done in R 3.3 using phenology packages version 5.1.1 [18]
