New #ornithology paper out in @ecography.bsky.social! The tendency of birds to return to the same breeding area in different years varies wildly among species. We show that breeding site fidelity is much lower in #shorebirds nesting in the #Arctic tundra than in those nesting in other habitats. 1/n
Map showing the geographic locations of shorebird populations included in the study, alongside four Arctic-breeding shorebird species with low breeding-site fidelity: Red Phalarope, Long-billed Dowitcher, White-rumped Sandpiper, and Pectoral Sandpiper.

Mehr5,7,8Many animals produce courtship sounds, and receivers prefersome sounds over others. Shared ancestry and convergentevolution may generate similarities in preference across speciesand underlie Darwin’s conjecture that some animals “havenearly the same taste for the beautiful as we have.” In this study,we show that humans share acoustic preferences with a rangeof animals, that the strength of human preferences correlateswith that in other animals, and that humans respond fasterwhen in agreement with animals. Furthermore, we foundgreatest agreement in preference for adorned, ancestral, andlower-frequency sounds. humans’ music listening experiencewas associated with preferences. These results are consistentwith theories arguing that biases in processing sculpt acousticpreferences, and they confirm Darwin’s century-old hunchabout the conservation of aesthetics in nature
