Mosquitoes (circles) can exist as susceptible (SM), latently infected (EM) and infectious (IM); Birds (squares) can exist as susceptible (SB), infectious (IB), or recovered (RB), moving between compartments according to different rates. Total number of mosquitoes and the total number of birds are provided by NM and NB. The biting rate (a), the per contact transmission probability mosquito-to-bird (c), the mortality rate (μA) and the rate with which mosquitoes move from latently infected to infectious (k), are temperature (T) depended. The per contact transmission probability bird-to-mosquito (b), the bird recovery rate (g), and the bird mortality rate (μV) are constants.
