==Behaviour==
[[File:Grasshopper Warbler Locustella naevia by Dr. Raju Kasambe.jpg|thumbnail|Grasshopper warbler (''Locustella naevia'')]]
Apart from their migration, grasshopper warblers rarely fly much, but spend their time scurrying through dense vegetation, flitting from twig to twig or running along the ground. It has a peculiar high-stepping gait and long stride as it moves along horizontal stems, looking slender and tapering. It seldom flies, soon diving back into cover, and when it alights it often raises and flares its tail to show its streaked under-tail coverts. It has been known to feign injury in order to distract a potential [[Predation|predator]].<ref name=Witherby/>

===Breeding===

Male common grasshopper warblers try to attract females by displaying to them. They walk or run along twigs with tail spread, fluttering their wings as they raise and lower them, often carrying a grass or leaf in their beak. In the air, with wings well extended and fluttering, they spread their tail and fluff their feathers.<ref name=Witherby/>

Both sexes take part in nest-building. The nest is well-concealed and built close to the ground in such places as grass tussocks, [[Ulex europaeus|gorse]] bushes, [[Willow|osier]] beds, [[reed bed]]s, tangled hedgerows, scrub and among coarse [[Calluna|heather]] plants on moorland. It varies in size and shape but is constructed of [[grass]]es, [[Cyperaceae|sedges]] and [[moss]]es and often lined with fine grasses. A clutch of four to six eggs is laid. These are creamy white speckled with fine reddish spots, usually randomly distributed but sometimes merged into blotches or zones.<ref name=Coward/> The eggs measure {{convert|18|by|14|mm|abbr=on}} and weigh about {{convert|1.7|g|2|abbr=on}}. Both parents are involved in [[Egg incubation|incubating]] the eggs which takes about fourteen days. The chicks are [[altricial]] and are fed on insects. They [[fledge]] in twelve to thirteen days and there are usually two broods in the season. Young birds become mature at a year old and the highest recorded age for this species is five years.<ref name=BTO/>

===Food and feeding===
The common grasshopper warbler is [[Insectivore|insectivorous]], feeding on a wide range of invertebrates. Its diet includes [[Fly|flies]], [[moth]]s, [[beetle]]s, [[aphid]]s, [[Dragonfly|dragonflies]] and [[Mayfly|mayflies]] and their [[larva]]e. [[Spider]]s and [[Woodlouse|woodlice]] are also eaten and the chicks are fed on aphids, green [[caterpillar]]s, woodlice and flies.<ref name=Witherby/>
