Survival
Egg survival and hatching success varies depending on the habitat, and appears to have declined in some habitats over the past decade.
Main causes of nest failure are predation, agricultural activity and desertion. While the birds often re-lay, changes in cropping practices often result in the habitat being unsuitable for replacement clutches because the vegetation has grown too tall, thus shortening the potential breeding season.
Only about 25-40% of chicks survive to fledging. Most of the chick mortality occurs in the first few days after hatching, when chicks are most vulnerable to cold or wet weather, and when they may be undertaking hazardous journeys from nesting to feeding areas. The further chicks have to go, the lower their survival.
Once the birds have reached adulthood, they can expect to live a further 4-5 years. The oldest known individual was about 20 years. Lapwings normally breed one year after fledging.
