Although 3 different bird species all
inhabit the same type of tree in an area,
competition between the birds rarely
occurs. The most likely explanation for
this lack of competition is that these
birds
(1.) are unable to interbreed
(2.) have a limited supply of food
(3.) share food with each other
(4.) have different ecological niches
