The warblers aren't in competition with one another because the different kind of warblers (which may live in the same tree) do not feed in the same regions of the spruce of the tree.For example: The Cape May warbler spends its time in the very top of the tree. The yellow-rumped warbler on the other hand, looks for food at the bottom third of the tree. The bay-breasted warbler stays for the most part in the middle branches of the tree.Their respective niches makes the birds interact in a mutualistic way.
