Revealed: the secret life of godwits

To find out more about birds such as the black-tailed godwit, ecologists have been conducting long-term population studies using standardized information on reproductive behaviour–such as dates of egg-laying or hatching and levels of chick survival. New information gathered using geolocators on godwits in the Netherlands shows that traditional observation methods can lead to inaccurate data. The study was published in the April-issue of the Journal of Avian Biology.
