A parasitic relationship. The Cuckoo lays its egg in a warblers (E.g. Reed warbler) nest and the cuckoo hatch-ling expels the eggs of the warbler. Therefore one species (the Cuckoo) benefits and the other one is at a disadvantage (the warbler). So the symbiotic relationship is parasitic.
The Cuckoo bird lays its eggs in the Warbler's nest, tricking the Warbler into raising its young. This is an example of brood parasitism, where the Cuckoo benefits by having its chicks raised by another species.
Feeding together would probablybe a better description of their association. While cattle (or other large, grazing animals) are grazing, insects and other preys are disturbed, making it easier for the cattle egret to catch them. Cattle egrets are feeding on grasshoppers, crickets, flies, moths, spiders, frogs, earthworms. More info on cattle egret could be found on http://en.wikipedia.org/wiki/Cattle_Egret
a cuckoo
The cuckoo bird lays its eggs in the nest of a different species of bird, sometimes pushing the old eggs out of the nest and laying new ones, or laying thier eggs ontop of the old eggs. the cuckoo will pick a next in which the eggs look similar to thier own. they will not sit on these eggs, but let the other bird sit on them, occationally checking the bird to see if it is still sitting.
