The dynamics of a Hawk–Dove population in our new model with initial conditions $q_h(0)=0.7$ and $n(0)=147$. Model parameters: $W=0.8$ , $d=0.5$, $\mathrm{\Psi }=0.06$, $\mathrm{\Phi }=0.08$. This case has background fitness components 10 times larger than in Fig. 1. The behaviour of the system and the restpoint have changed; however, the vector field depicted by the arrows shows that the system is still far from timescale separation
