The Eurasian Curlew has been on the IUCN Global Red List, in the Near Threatened category, since 2008.

The very latest on why Curlews are declining in UK – not an easy read, but full of up-to date insights. The first ever large-scale assessment of changes in British Curlew populations (both upland and lowland). The paper finds greatest support for the detrimental effects of arable farming, afforestation and generalist predation on both Curlew abundance and population change. It calls for rapid establishment of intensive studies of identify the drivers of the patterns observed, such as: monitoring of key land uses such as agriculture, forestry and grouse moor management (e.g. burning, cutting, and predator control); predator abundance; invertebrate resources; and importantly, reproductive success.

Classic paper, mainly dealing with Lapwing, Snipe and Redshank in England and Wales (not Scotland) below 600 feet (183 m), but some references to Curlew; survey methodology of three monthly visits in April, May and June has proved to be insufficient for good monitoring of breeding Curlew. Suggests population of 750 pairs, on 15% of sites visited, the majority in northern England and Wales; numbers of Curlews have declined in the south and are very low. Little known about Curlew’s detailed breeding habitat requirements, though appears to be limited to rough grazings and damp pastures in Scotland.

The classic review of metal ring recoveries, quite old, but still highly relevant. It would be good to have an update, and more information on recoveries of colour rings.
