Abstract: Migratory birds are essential factors in the epidemiology of infectious diseases. This article discusses a new predator–prey model for susceptible migratory birds, infected migratory birds and predator species. Time-dependent coefficients are considered with the Leslie–Gower Holling-type II schemes and the saturated recovery rate in this new model. Some sufficient conditions for the extinction and permanence of diseases are established on the basis of relatively weak assumptions. The global attractiveness of the model is also given through spectral analysis and Liapunov function. Our results reveal that the infective species is extinct if the upper threshold value R∗≤1, whereas the model is permanent if the lower threshold value R∗>1. Numerical simulations are conducted to confirm the obtained results.
