Morphology

The Platysteiridae are small to medium sized passerines. They have short legs and an upright stance while perched. The tail length is variable, with the Dyaphorophyia wattle-eyes and batises having short tails and the Platysteria wattle-eyes and shrike-flycatchers possessing longish tails. The bill

s, although spiders, millipedes and scorpions are also taken, and there are even records of small lizards being consumed. Amongst the insect prey a number of different types are eaten; beetles, grasshoppers and other Orthoptera, flies, mosquitoes, wasps, termites, mantises and others all being recorded. Prey is taken by members of the family either as individuals or in family groups. Some species will also forage as part of mixed species feeding flocks, a technique that has been shown to confer some advantages. The different species and genera use a variety of methods to obtain prey, ranging from foliage-gleaning to flycatching.
