In waders (shorebirds), the main moult (molt) usually takes place after the migration that follows the breeding season. Golden Plovers adopt a different strategy, starting wing moult while still nesting. Given that these adult birds are not going to fly anywhere any time soon, this seems like a very efficient strategy. So, why do Icelandic and Scandinavian Golden Plovers moult differently? Is this a reflection of available resources?

Moult is an energetic process, especially the post-breeding moult, which includes a change of all of the wing and tail feathers. To complete the whole process, birds ideally need to find a three-month period when resources are good, climatic conditions are benign and there is no need to migrate.
