Clim. Change<\/jats:italic><jats:bold>8<\/jats:bold>, 313\u2013318). This group, the most threatened of all birds, is therefore prone to spatio-temporal mismatches with their food resources. Yet, other aspects of the breeding phenology may also have a marked influence on breeding success, such as the arrival date of adults at the breeding site following winter migration. Here, we used a large tracking dataset of two congeneric seabirds breeding in 14 colonies across 18\u00b0 latitudes, to show that arrival date at the colony was highly variable between colonies and species (ranging 80 days) and advanced 1.4 days\/year while timing of egg-laying remained unchanged, resulting in an increasing pre-laying duration between 2009 and 2018. Thus, we demonstrate that potentially not all components of seabird breeding phenology are insensitive to changing environmental conditions.<\/jats:p>","DOI":"10.1098\/rsbl.2019.0634","type":"journal-article","created":{"date-parts":[[2019,10,23]],"date-time":"2019-10-23T12:47:08Z","timestamp":1571834828000},"page":"20190634","update-policy":"https:\/\/doi.org\/10.1098\/crossmark-policy","source":"Crossref","is-referenced-by-count":20,"title":["Earlier
