i haven't seen muscovy ducks in the wild before, only in captivity like in allotment gardens. These three specimen look quite impressive.
Where i live, they are often accompanied by runner ducks,
like these guys here:
they eat snails, that's why they have become quite popular with gardeners. Among ducks, they are defo the sweetest ones.
Back then, we decided to keep the location of the peregine's nesting box a secret mostly bc of a rise of crime related to birds of prey. There are stories of people entering buildings and stealing the eggs from the nesting boxes. Others, mostly pigeon breeders, lay out toxic baits, e.g. dead pigeons that were coated with poison.
There was a sad case filmed in Zuerich with a female peregrine dying in the nest next to her young ones.
So, yes, I think it was a good decision not to make it public.
