To the best of my knowledge birds usually recover from the lesion completely, but the proportions are horrifying. Imagine a fucking apple-sized crater of pus and dead tissue next to your face.
Using tooth paste feels ghetto, but I suppose it's the cheapest way to keep the open sore from collecting dirt.
This is the Malm Whale, the only taxidermied blue whale in the world, in the Gothenburg Natural History Museum in Sweden. Dates from 1865, and it used to open up to let people sit in a little lounge inside
Then in the 1930s they found a couple fucking in it, so now they only open it on election day.
