At #BOUasm24 Katherine Whyte is trying to understand the mechanisms behind the impacts of offshore wind developments on seabirds To understand predator-prey interactions, they are collecting GPS tracking data of tagged seabirds and conducting acoustic and trawl surveys of fish #ornithology

Christian Schano has just spoken at #BOUasm24 on utility-scale photovoltaic power plants in the Alps
Christian found there is a critical need to comprehensively assess the impact of alpine solar farms on birds and biodiversity

Impacts on birds can be minimised by careful siting, and solar farms might be better than the farmland they replace. But even if we pessimistically assume wind and solar farms are *entirely devoid* of bird life, impacts on national populations are likely to be negligible. #BOUasm24 #ornithology

The renewable transition in the UK requires a relatively small area of land - just 0.9% of land directly impacted, resulting in a probably tiny impact on national food production. #BOUasm24 #ornithology

Joshua Copping is talking at #BOUasm24 about the area of land needed for onshore renewable energy generation, finding that ambitious deployment of onshore wind and solar caused only a minor (<1%) reduction in UK food production

Josh is presenting our recent paper (www.sciencedirect.com/sci…) which explores the capability of UK land to accommodate future onshore renewables, then models the impact of renewables + other land-based climate change mitigation measures on birds 🐦food 🍞 and GHGs 💨 #BOUasm24 #ornithology

Back to the land, with Josh Copping (@rspb.bsky.social). Most of the conference has focused on the energy transition, but net zero is likely to require much wider changes to land management and use. #BOUasm24 #ornithology

At #BOUasm24, Mike Heath is talking about assessing the effectiveness of compensatory measures for the effects of #offshore #windfarms on #seabirds.
The number of offshore turbines is expected to quadruple by 2050... What effects could this have on seabirds?

Ilaria Fozzi is talking at #BOUasm24 about the risks of wind turbines for vultures. By using publicly available datasets, they found varied risk to vulture's feeding grounds based on the used map. Mapping planned turbines is crucial for forecasting collision risks.

Next, Ilaria Fozzi takes us into the terrestrial realm, and she's got VULTURES. Griffon's are prone to collision with turbines. GPS tags used to identify foraging grounds. Risk of collision depends on turbine dataset used #BOUasm24 #ornithology

We also need to apportion impacts across the flyway during the non-breeding season, which means we need to know where birds from specific colonies migrate to. #BOUasm24 #ornithology

Failing to account for density dependent regulation of population size can lead to unrealistic projections - we should be moving towards a density-dependent framework for PVA #BOUasm24 #ornithology

What happens when we allow demographic variables to trend over time? Even a weak negative trend in fecundity (green projection vs blue projection) has a strong impact on predicted population viability conbio.onlinelibrary.wile…. #BOUasm24 #ornithology

We can also account for immigration to focal populations using Integrated Population Models e.g. here for Skomer Kittiwakes nsojournals.onlinelibrary…. #BOUasm24 #ornithology

Temporal change in the contribution of immigration to population growth in a wild seabird experiencing rapid population decline
The source–sink paradigm predicts that populations in poorer-quality habitats (‘sinks') persist due to continued immigration from more-productive areas (‘sources'). However, this categorisation of po...

So, PVA is useful but has poor predictive accuracy. We can impute gaps in colony-specific demographic profiles using life history theory (high fecundity = low survival) - more biologically realistic than assigning average demographic variables across all colonies #BOUasm24 #ornithology

Next Keynote speaker is Cat Horswill @cathorswill.bsky.social. Predicting the impacts of offshore wind on seabird populations using e.g. Population Viability Analysis is hard because we lack population-specific information, so need to make simplifying assumptions #BOUasm24 #ornithology
