The level of sea bird deaths has been astronomical. There were at least 30 on one 500m stretch of lunan bay a few weeks ago. Mostly Guillimots.
I don’t see how there can be another lockdown as bird flu is clearly now endemic to Britain. The strange thing for me to understand is how it took years rather than weeks to spread around our marine birds given that there’s a lot of cross over between habitats of sea birds, waders, resident and migratory geese and other birds. Viral infections usually result in initial exponential infection/harm/symptoms followed by tailing off with smaller ‘peaks’ due to host stress or previously isolated subsets of a pop becoming isolated.
