Ep. 7: Brown-headed Cowbird
Most birds build nests, lay eggs, and spend weeks raising their young. The Brown-headed Cowbird has taken a completely different approach. In this episode of The Neighborhood Naturalist, we explore one of North America’s most fascinating and often misunderstood birds.
In This Episode
* Why a Lark Sparrow was raising a Brown-headed Cowbird
* How brood parasitism works
* Why cowbirds originally followed bison across the prairie
* What Brown-headed Cowbirds eat
* How to identify males and females
* What their distinctive song sounds like
* The surprising “Mafia Hypothesis”
* Why young cowbirds still recognize other cowbirds despite being raised by different species
The next time you’re outside, listen for the Brown-headed Cowbird’s distinctive bubbling whistle. If you spot one, spend a few minutes watching its behavior. Is it feeding on the ground? Following people, livestock, or lawn mowers? Perched high in a tree calling?
If you see one, consider recording your observation in eBird. Every checklist helps scientists better understand bird populations and migration while helping you become a more observant naturalist.
