Appearance, physical description and identification
The jack snipe (Lymnocryptes minimus) is the smallest snipe, measuring 15 to 20 cm in length and weighing 30 to 100 grams. The wingspan is 35 to 40 cm.The upperparts of jack snipe are brown and heavily mottled. The underparts are paler. A dark stripe runs from the base of the bill through the eye. The wings are short and narrow. There are two yellow back stripes. The trailing edge of the wing is white.
There are two pale lateral crown-stripes. The irises are blackish. The jack snipe bill is pale grayish brown and the distal end is blackish. The bill is relatively short for a snipe. The feet are pale yellow. The jack snipes call is a series of “ogogogogogogog" and drumming sound.

Origin, geographical range and distribution
The jack snipe species are distributed in northern Asia, northern Europe, southern and western Europe, Middle East, Mediterranean region, central Africa, Indian subcontinent and southeast Asia.In India, these jack snipe species are distributed in the states of Jammu and Kashmir, Himachal Pradesh, Punjab, Haryana, Uttar Pradesh, Uttarakhand, Rajasthan, Gujarat, Madhya Pradesh, Bihar, West Bengal, Meghalaya, Jharkhand, Odisha, Maharashtra, Telangana, Andhra Pradesh, Goa, Karnataka, Tamil Nadu and Kerala.
The Important Bird and Biodiversity Areas (IBA) of these jack snipe species in Russia are Yuzhskoe lake-land, Basins of the Schuchya and Khadytayakha rivers, Sysola river, Adovo-Chugrumski wetland, Lapland Biosphere Reserve, Kumikushski wetland and Lower Ob'.
The IBA of these jack snipe species in Finland are Värriö-Tuntsa, Saariselkä, Koilliskaira, Oulanka-Sukerijärvi, Luosto, Litokaira, Lemmenjoki-Hammastunturi-Pulju, Runkaus-Saariaapa-Tainijärvet and Kemihaara (Vuotos) mires and forests.

Ecosystem and habitat
These jack snipe species do not normally occur in forest. These species occur in altitudes from 0 to 100 meters. The artificial ecosystems of these birds include seasonally flooded agricultural fields, damp pastures and water meadows.The natural ecosystems of these snipe species are tropical and subtropical seasonally wet grasslands, margins of rivers and streams, intertidal marine marshes with emergent grasses, peatlands, marshes, swamps, bogs, floodplains, waterlogged mudflats and brackish wetlands.
Diet and feeding behavior
The diet of these jack snipe species is mostly earthworms. Adult and larval insects, annelid worms, small snails, aquatic plants and seeds are their primary food. They probe the soft mud with their bill for worms and insect larvae.Reproduction and breeding habits
The breeding season of these jack snipe species is from May to August in most of the breeding grounds. These birds disperse into solitary pairs for breeding. The males perform aerial display during courtship and make drumming sounds by vibrating their modified outer tail feathers.The breeding sites are selected in well-hidden hummocks of sphagnum moss or grass tussocks in open grassy wetlands, marshes, bogs and swampy grounds in northern taiga and tundra zones. The typical jack snipe clutch contains 3-4 speckled, pale yellow eggs.
Migration and movement patterns
The jack snipe species are highly migratory birds.These jack snipes breed from May to August in northern Russia, north Norway, north Sweden, northern Finland, eastern Estonia and northern Belarus. Then the adults undergo a flightless moulting period close to the breeding grounds.
These snipe species leave the breeding grounds by the end of September for wintering in southwest Europe, Middle East, Mediterranean region, central Africa, Indian subcontinent and southeast Asia. The return trip to the breeding grounds takes place in March and April.
Conservation and survival
The global population size of the jack snipe (Lymnocryptes minimus) is estimated to be about 1,000,000 individual birds. The overall population trend of these snipe species is considered to be stable. Throughout its range it is reported to be fairly common. The generation length is 5.4 years. Their distribution size is about 10,600,000 sq.km.The jack snipe (Lymnocryptes minimus) does not approach the thresholds for being Vulnerable, either under the range size criterion, or under the population trend criterion or under the population size criterion. Degradation of wetland habitats, hunting for food and sport hunting are the main threats that may endanger the survival of these snipe species.
IUCN and CITES status
The IUCN (International Union for Conservation of Nature) has categorized and evaluated the snipe species and has listed it as of "Least Concern". The CITES (Convention on International Trade in Endangered Species of Wild Fauna and Flora) status is ‘Not Evaluated’ for the jack snipe (Lymnocryptes minimus).| Taxonomy and scientific classification of Lymnocryptes minimus | |
