Here, we simultaneously tracked 96\u2013116 breeding Ad\u00e9lie penguins (Pygoscelis adeliae), corresponding to 35.6\u201343.0% of active breeders in a colony, across 653 foraging trips, and examined their movement decisions. We found that foraging site selection was most often predicted by individuals\u2019 own previous space use, but in 17.1% of trips, it was better predicted by incorporating the prior space use of conspecifics that departed the colony together. Notably, the simulation with random replacement tests indicated that group departure is a prerequisite for the effects of conspecifics on foraging site selection. Furthermore, penguins with unsuccessful prior trips, quantified as a reduced frequency of foraging dives, changed foraging sites more frequently than those with successful prior trips, relying more on the experiences of conspecifics. These findings suggest that group departure and travel facilitate social information acquisition, particularly for individuals that have recently been unsuccessful in foraging trips. Our study highlights the strategic use of social information and its potential benefits for foraging penguins.<\/jats:p>","DOI":"10.1098\/rspb.2026.0122","type":"journal-article","created":{"date-parts":[[2026,6,10]],"date-time":"2026-06-10T00:15:52Z","timestamp":1781050552000},"source":"Crossref","is-referenced-by-count":0,"title":["Unsuccessful foragers acquire social information through group departure and travel in penguins"],"prefix":"10.1098","volume":"293","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4039-5583","authenticated-orcid":false,"given":"Toshitaka","family":"Imaki","sequence":"first","affiliation":[{"name":"The Graduate University for Advanced Studies, 1","place":["Tachikawa,, Tokyo 190-8518,, Japan"],"department":["Department of Polar Science,"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nobuo","family":"Kokubun","sequence":"additional","affiliation":[{"name":"The Graduate University for Advanced Studies, 1","place":["Tachikawa,, Tokyo 190-8518,, Japan"],"department":["Department of Polar Science,"]},{"name":"National Institute of Polar Research, 2","place":["Tachikawa,, Tokyo 190-8518,, Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9868-0408","authenticated-orcid":false,"given":"Akinori","family":"Takahashi","sequence":"additional","affiliation":[{"name":"The Graduate University for Advanced Studies, 1","place":["Tachikawa,, Tokyo 190-8518,, Japan"],"department":["Department of Polar Science,"]},{"name":"National Institute of Polar Research, 2","place":["Tachikawa,, Tokyo 190-8518,, Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"175","published-online":{"date-parts":[[2026,6,10]]},"reference":[{"key":"2026081108585465600_R1","doi-asserted-by":"crossref","DOI":"10.1093\/oso\/9780198508175.001.0001","volume-title":"Living in groups","author":"Krause","year":"2002"},{"key":"2026081108585465600_R2","doi-asserted-by":"crossref","first-page":"511","DOI":"10.1098\/rspb.2002.2267","article-title":"Information transfer about roosts in female Bechstein\u2019s bats: an experimental field study","volume":"270","author":"Kerth","year":"2003","journal-title":"Proc.
