d in their habitat. Consequently, birdwatchers have developed a specialised technique for finding them. This involves walking through its marshy habitat until a bird is disturbed and flies up. Jack Snipe will squat down and not flush from cover until an intruder is quite close. They then quietly fly a short distance before dropping back into vegetation.

Feeding

They forage in soft mud, probing or picking up food by sight. They mainly eat insects and earthworms, also plant material.

Breeding

The male performs an aerial display during courtship, during which it makes a distinctive sound
Drumming (snipe)
Drumming is a sound produced by snipe as part of their courtship display flights. The sound is produced mechanically by the vibration of the modified outer tail feathers, held out at a wide angle to the body, in the slipstream of a power dive. The display is usually crepuscular, or given...
