What a charmed LIFE they have.  

I watched a show on TV about a specific kind of ant that not only lived alongside aphids, but actually herded them like cattle! They had a symbiotic relationship with each one being helped by the other.

The ants ate secretions from the aphids, while the aphids were protected from the elements and other insects by the ants. When it rained, the ants would pick up and carry the aphids to safety, then would carry them to new plants so they could feed.

It was awesome to watch! Not quite the same as in the animal world but these insects proved that they could have an extremely sophisticated system in place that would benefit both. Truly amazing!

I think you have named al I know about.

Yes, animals are fascinating. You have provided some great examples of the relationship between various animals and how they can benefit one another.
The relationship you are referring to is called symbiotic. Here are some further examples:

"The Goby fish and a shrimp: The shrimp digs and cleans a burrow in the sand in which both the shrimp and the Goby fish live. The shrimp is almost blind and this leaves it vulnerable to predators. The goby fish touches the shrimp with its tail to warn it of impending dangers, and both shrimp and goby fish quickly retreat into the burrow."

"Clownfish and sea anemones: Another example is the clownfish that lives among the tentacles of tropical sea anemones. The territorial fish protects its host from anemone-eating fish, and in turn the stinging tentacles of the anemone protect the clownfish (mucus on the clownfish protects it from stings)."

"The bee and the flower: Bees fly from flower to flower gathering nectar, which they make into food, benefiting the bees. When they land in a flower, the bees get pollen on their hairy bodies, and when they move to the next flower, some pollen rubs off, pollinating the plant. This benefits the plants. In this symbiotic relationship, the bees eat and the plants reproduce."

i have seen somebirds seating on cow / buffalo
those mosquitos ..

does the bacterias in our stomach count ??

cheers

Some birds like to hang out with cows and horses in the fields. I also knew of a horse that needed a goat to stay in her stall before her races.
