Résumé

Aim: Many populations of migratory birds are currently declining. Understanding space use throughout the entire annual cycle, as well as migratory connectivity (i.e., geographic linkage of individuals and populations across different stages of the annual cycle), can improve our ability to identify factors driving population declines and influencing extinction risk. The main objectives of our study were to (i) document the space use and phenology of migration during the non-breeding period and (ii) quantify the degree of migratory connectivity across the range of the American Golden-Plover(Pluvialis dominica) breeding across the North American Arctic.

Location: American Golden-Plovers that breed across their entire breeding range (northern North America) and migrate up to their main wintering site located in South America.

Methods: We used archival light-level geolocators to track the migration. We quantified migratory connectivity based on the non-breeding range spread of all individuals and the breeding population spread. We used Mantel tests to evaluate whether the relative spatial configuration of the sampled breeding area was preserved on the non-breeding ground.
