A satellite tracking study will shed new light on one of the UK's most elusive bird species.
The Game & Wildlife Conservation Trust has been following woodcock for the last two years in order to record the bird's migratory habits.
Results of the study are now due to be revealed at an event in Gloucestershire hosted by the charity's woodcock expert Dr Andrew Hoodless.
Researchers attached satellite transmitters to 24 woodcock from different locations ahead of the long flight back to their breeding grounds.
Already the research has revealed that, despite its diminutive size, a migrating woodcock can fly for 18 to 24 hours non-stop, covering distances of more than 1,000km (625 miles) in that time.
Some of the woodcock wintering in Britain originate from breeding grounds as far east as central Siberia, some 7,000km (4,380 miles) away.
