Differences in body sizes may create a trade-off between foraging efficiency (foraging gains/costs) and access to resources. Such a trade-off provides a potential mechanism for ecologically similar species to coexist on one resource. We explored this hypothesis for tundra (Cygnus columbianus) and trumpeter swans (Cygnus buccinator). a federally protected species. https://www.hindigyanvishv.com/special-deal-Fluffy-White-Feather-Tinsel-Angel-Halo-quick-deal/
