Despite their harmless appearance though, they are a friend to no one. Cowbirds are selfish and greedy and they pave a path of destruction everywhere they go. Unfortunately, I’ve met some people who have similar habits. Cowbirds act the way they do thanks to thousands of years of survival of the fittest.
Male Brown-headed Cowbirds have glossy black plumage and a rich brown head that often looks black in poor lighting or at distance. Female Brown-headed Cowbirds are plain brown birds, lightest on the head and underparts, with fine streaking on the belly and a dark eye.
The adult cowbird may actually eat an egg or two of the host bird. Babies of the European cuckoo, also a notorious brood parasite, go a step further and kill the other babies when they hatch. But baby cowbirds usually do not kill their nest mates.
Brown-headed Cowbird
Brown-headed Cowbirds are smaller with a shorter tail than Common Grackles. Adult males have a brown head whereas Common Grackles have a blueish head.
Cowbird chicks don’t directly harm their nestmates (by pushing them out of the nest, for instance, like some cuckoo species), but tend to grow faster and outcompete them for resources.
Molothrus genus Molothrus New World bla… blackbird cowbird.
Differences. When it comes to differences, brown-headed cowbirds are smaller than American crows. The most noticeable difference is these birds have brown heads. They also have finch-like, small heads and smaller bills than those of American crows.
Cowbirds: corral, herd.
Current Distribution. In California, brown-headed cowbirds are a common resident and summer visitor that breed throughout much of the state.
cowbird, any of five species of birds that belong to the family Icteridae (order Passeriformes) that are named for their habit of associating with cattle in order to prey upon insects stirred up from vegetation.

Mostly seeds and insects. Seeds (including those of grasses, weeds, and waste grain) make up about half of diet in summer and more than 90% in winter. Rest of diet is mostly insects, especially grasshoppers, beetles, and caterpillars, plus many others, also spiders and millipedes.
While the brown-headed cowbird is native to North America, it is a much worse villain than the European starling — an invasive species that has expanded like wildfire in the U.S. since it was introduced in the late 1800s — ever thought about being.
Several species of cowbird are native to the U.S., the Caribbean, and Mexico. The Brown-headed Cowbird (Molothrus ater) was originally native to the Great Plains where it foraged alongside migra- tory bison herds. Today, it is mainly found along- side livestock, in feedlots, and in other agricultural areas.
Cattle Egrets have many names around the world, usually referencing the grazing animals they team up with to forage. In various languages they are known as cow cranes, cow herons, cow birds, elephant birds, rhinoceros egrets, and hippopotamus egrets.
Brown-headed cowbirds (Molothrus ater) parasitize nests of songbirds by sneaking in, laying their eggs in the nest and watching as songbirds of another species raise the cowbird chicks as their own.

There are two other cowbird species with very limited ranges in the United States: the shiny cowbird (Molothrus bonariensis), only found in most southern Florida, and the bronzed cowbird (Molothrus aeneus), only found in southern Texas and southeastern Arizona.

Cowbirds ate insects stirred up by bison and also sat atop these large herbivores picking off ticks and insects that crawled across their bodies.
The cattle are simply providing for themselves their daily needs, but as a result, they are also providing for a local bird. This is a great example of a commensalism symbiotic relationship; it benefits the needs of one without risk to the other.
They are found in almost all the continents of the world including North America and are native to Africa. Due to their habit of following cattle around, they are also known as cowbirds, cow herons, cow cranes, rhinoceros egrets, or elephant birds.
Herd mentality
Buffalo are often pictured covered in mud with a bird on their back. The mud helps buffalo get rid of ticks and parasites that latch onto their skin. Birds such as oxpeckers, for example, ride on the back of the buffalo and eat lice, fleas, and other parasites while getting a lift.
