Cowbird/Bison: Commensalism by Daniel Cohen on Prezi
A female brown-headed cowbird at a backyard bird feeder is bad news. In the days of roaming bison herds, the impact of cowbirds on. Today most people don't know about the buffalo bird/bison association and how this bird adapted its entire life history around migrating bison. What is the symbiotic relationship between bison and cowbirds? Cowbirds follow herds of buffalo to eat the flied and bugs that areattracted to the buffalo.
Oxpeckers consume dandruff and scar tissue, and have been known to open up wounds on their host to eat the blood and scabs, potentially slowing the healing process. Mutualism There are various types of symbiotic relationships. Mutualism is a symbiotic relationship that benefits both organisms. In the case of the relationship between the oxpecker and his bison-like hosts, the oxpecker benefits from having a steady supply of food, while the host benefits from having parasites cleaned from her body.
Some scientists debate if the relationship truly is mutual however, as the host does not benefit in the same way, if at all, as the oxpecker. Animals, such as the elephant and topi, actively brush away oxpeckers, signalling that there may be little benefit to their relationship. Semi-Parasitic The red-billed oxpecker in particular is suspect of being semi-parasitic. Prairie dogs shouted their alarm calls at me across the windswept prairie.
I felt like Laura Ingalls Wilder as I strolled over the rolling prairie hills, dodged buffalo chips on the trail, and photographed wildflowers taking advantage of spring. Thankfully, the hot sun was offset by a cooling breeze. Twice the trail ran right through the center of prairie dog towns. Their alarm calls were incessant and pushed before me in a wave, with the closest little rodents chattering from out of sight inside the entrance to their burrow.
The bell-like tones of meadowlark calls rang out across the prairie, and repeatedly I searched for the vocalists who sounded much closer than their actual perch. The volume of their songs was impressive.

Back at my car, I quickly settled in for an afternoon of driving west. Pa Ingalls would have understood the feeling. Where the park road met the highway, a pair of bison grazed on the shoulder. If it was just those two great, shaggy beasts, I might not have stopped, but around their heads fluttered personal flocks of brown-headed cowbirds.
Glad that no one was with me to roll their eyes at my excitement, I swung onto the shoulder, rolled down a window, and picked up my camera from the passenger seat. Now, brown-headed cowbirds are not my favorite animals. Your remarks on symbiosis got me thinking about our hens. They eat the grass, weeds and insects in the yard. In turn, their droppings attract more insects and help fertilize the grass and weeds.
I feed them an organic layer feed and they reward me with rich, flavorful eggs. I should go on to say that when their laying days are over, they will provide me with meat, however, that won't happen! They will continue to provide me with laughs and lots of affection.
A couple of examples from the same cycle. Good job and keep thinking. Commensalism, may be looked at as Symbiosis, but isn't. One of the organisms benefits it receives something it needs.
The other organism does not benefit, but neither is it harmed. An example of commensalism is the relationship between bison and cowbirds.
As bison wander through the grasslands feeding, they stir up insects.

Cowbirds follow the bison, eating insects that are stirred up. In this relationship, the cowbird benefits The bison does not benefit, but it is not harmed either by the cowbird eating insects. Cowbirds were originally called Buffalo birds by early trail herders and cowboys. Once bison were eliminated, cowbirds adapted to following herds of cattle, hence their name. Another example of commensalism is the relationship between the Cactus Wren and Cholla Cacti.
Cactus wrens often build their nests in Cholla cacti. The spines of the cactus help protect the nest from predators.
In this symbiotic relationship, the Cactus wren receives something it needs - nest protection. The Cholla Cactus does not benefit and it is not harmed by the nesting cactus wrens. In parasitism, one organism feeds off another. The parasite is the organism that gets fed. The host is the organism that is fed upon. The parasite benefits, but the host is harmed in this relationship. Cowbirds make this list too. You can come up with a long list of Parasites. Powdery and downy mildew on your plants.

Okay, here is my list of Symbiotic relationships. I'll keep it short. Lichen is one amazing organism. Probably Symbiosis at its best. You take some algae and some fungus.

They manage to find each other and a love affair like no other is formed. The algae provides moisture all life needs water and the fungus provides the food.

One can't live without the other for any length of time, so they get together and for 'Lichen'. There are different kinds and colors of lichen.
Lichen will attach to just about any object trees, buildings, rocks, sidewalks, dead or alive, tropical or desert. Remove one, and the other dies too. A certain species of this type of crab is sometimes involved in a symbiotic relationship with a sea anemone, where the sea anemone is attached to the crab's shell.
Which type of crab is involved here? In this relationship, the sea anemone receives food and gets transported by the hermit crab, and the sea anemone, with its stinging tentacles, protects the hermit crab. A certain small African bird called the Honeyguide and the Honey-badger are involved in a unique type of symbiotic relationship.
The Honeyguide fans its tail and makes a special call to lead the Honey-badger to the bees-nest. After it has led it to the nest, the honey-badger rips the nest apart, and eats the honey and bee-larvae present inside. It is protected from the stings of the bees by its thick skin.
