This is one of my favorite projects that I have made. Sadly. USE TURBOWARP: https://turbowarp.org/1011388278
This is based of the hybridization of Blue-Winged (the blue circles) and Golden-Winged Warblers (the orange circles). Basically, when they hybridize, they make the Brewster's Warbler (red circles). When Brewster's hybridize with Blue or Golden-Winged Warblers, they produce the Lawrence's Warbler (green circles). When Lawrence's hybridizes with anything else, they go back to Blue-Winged.
