Cowbirds & Bison

Показать описание
Cowbirds & Bison - Cowbirds are native to North America and got their name because they like to hang out with cattle (and before cattle were introduced - with bison). Grazing cattle or bison stir up bugs as they graze so a choice place to catch an easy meal. They are considered brood parasites as they lay their eggs in other birds nests.This makes some sense as they followed the bison herds which ranged widely across the plains of North America before European colonization. This video shows juvenile cowbirds catching a ride on one of the bison at Tall Grass Prairie Preserve this morning.
