When we first played back the novel calls, the nestlings showed no response. We then played the unfamiliar call six times together with redstart alarm calls. After this training phase, nestlings responded to the novel call in the same way as to alarm calls of their own species.

New paper led by Jinggang Zhang just out in @royalsocietypublishing.org! We show that nestling redstarts learn to respond to calls of other species if hear them together with alarm calls of their own species doi.org/10.1098/rspb...

Males that returned to the study area also had higher siring success and stayed longer in the study area than males that had not been in the study area the previous year 5/6

Males that had higher siring success and had stayed in the study area for longer were more likely to return 4/6

However, a very small proportion of ~900 colour banded pectoral sandpipers did return to their former breeding site in the subsequent breeding season, with males returning more often (2.4%) than females (0.5%) 3/6

Satellite tagging showed that pectoral sandpipers typically do not return anywhere near their former breeding site, with a median dispersal distance between years of >800 km for both males and females 2/6

New paper on breeding site fidelity in pectoral sandpipers out in @asab.org! The pectoral sandpiper is a highly nomadic polygynous shorebird, but a very small proportion of individuals is nevertheless faithful to their breeding site between years 1/6 www.sciencedirect.com/science/arti...

New paper out in @rsocpublishing.bsky.social! Research from our group shows that males of the polygynous ruff visit many potential breeding sites within a breeding season, travelling up to 9000 km and visiting up to 23 different sites! royalsocietypublishing.org/doi/10.1098/... 1/7
