If the app doesn't give you any life history (it's instant, not via email), it either hasn't been added by IBGRG to the data the app uses or the ring code entered is incorrect.
You could instead email the sighting email [email protected], but it sounds like you aren't having much luck there

Apologies, I'm only responsible for developing and keeping the sightings app functional, I'm not part of IBGRG or responsible for keeping the data the app uses up to date. If you haven't already, I would try submitting the sighting through the app, as that should give you life history of the bird

A special thanks to my co-authors and funders. This work was completed as part of my PhD thesis at @biouea.bsky.social/@uniofeastanglia.bsky.social partnered with @audubon.org

We think this is because dispersal into new breeding areas is always passed to the next generation when born there – you only need to return to a known location. Conversely, a new non-breeding site isn’t automatically passed to the next generation.

Flocking was associated with significantly larger non-breeding range COA shift rates, particularly in mixed-age flocks. However, flocking had no significant effect on breeding range COA shifts.

The data goes into PGLS models weighted by uncertainty in COA shift rate.
One model for each season for a binary flocking var. for 122 species. Another model for each season where we categorise flocks as either age-separated or mixed-age, for 81 species.

N.B.: We do still lack published accounts of typical migratory flocking behaviour for many species! This includes whether a species flocks, typical flock size, age composition, species composition, etc.

We collated information on migratory flocking behaviour of North American migratory birds, building upon the Beauchamp et al. 2011 dataset with species accounts from Birds of the World Online and age-cohort timing calculated from USGS banding data.

To test this, we used 50-years of North American BBS and CBC #citizenscience data to quantify annual centres of abundance (COA) for breeding and non-breeding ranges across the contiguous USA and southern Canada. We then summarised the magnitude of the shift in COAs.

We hypothesised in species that migrate solo, inter-generational change may need change in genetics of migration distance/direction.
However, flocking migrants can benefit from social learning, which might act faster – but inter-generational learning can only happen in mixed-age flocks!

3/10

Species may need to shift their range to respond to environmental change, but for migrants this can be tricky as seasonal ranges that shift at different rates/directions can require a change to migratory distance/direction.
