The 'true' cuckooshrikes are usually found singly, in pairs, and in small family groups, whereas the minivets, flycatcher-shrikes and wood-shrikes more frequently form small flocks. There is a considerable amount of variation within the family as a whole with regard to calls, some call very infrequently and some, principally the minivets, are extremely vocal. These are mainly
insectivorous, and will take large hairy
caterpillars. They have also been recorded eating small vertebrates, and some fruit, seeds and other plant matter. Information about the breeding of this family is incomplete, with many species having never been studied. In all the species studied the cuckooshrikes are
territorial; in species that do not migrate these territories are maintained year-round. Cuckooshrikes are
monogamous, with the pair bonds apparently lasting throughout the year. Only one instance of non-monogamous breeding has been recorded, an instance of polygyny in
white-winged trillers in Australia, where one male aided two females in raising their young. Several species of cuckooshrike exhibit cooperative breeding. About four blotchy white, green or blue
eggs are laid in a cup nest in a tree. Incubation is about two weeks. ==List of genera==
