Why can all three species of wabler live in the same spruce tree?
In general, animals can coexist if they: eat different things in the same place, eat the same thing but at different times, or eat the same thing in different places or manners. In the case of warblers in the same tree, where they are eating the same food and at the same time of day (warblers are active at day and not at night), multiple warblers can feed in the same tree if they feed in different parts of the tree, or if they use different foraging techniques on the same area of a tree.
