The Cowbird

Brown-headed Cowbirds are brood parasites; they lay their eggs in the nests of other birds. Their involvement doesn't necessarily end with egg-laying, however. Brown-headed Cowbirds have been observed "farming" their hosts and engaging in retaliation when their eggs are destroyed or the host nest is abandoned. These tactics lead some to call the Brown-headed Cowbird the "Mobster Bird." This fun design is a play on the most famous movie mobster family of all time.
