No quiet moment; Theresa May calls snap UK election (BBC)

I had been waiting for a quiet moment to write about this, but there isn’t going to be a quiet moment, so now will have to do. [Update: these words went up on 3 Quarks Daily last Monday. On the Tuesday, Theresa May called a snap UK General election]

Debaters regularly accuse their opponents of using fallacies. These can be formal fallacies, such as simple errors of logic, or informal fallacies, such as appeal to authority, ad hominem and strawman arguments, among others.

One of the features of the walk up from the Rest and Be Thankful is the rock step, which has to be descended on the ascent and ascended on the descent. It sounds more exciting than it is, although it’s a real obstacle in icy conditions.

That was my first proper hill of the year, and a reminder that there’s an awful lot of up involved in going up a hill.

Whooper swans leaving Argyll

Yesterday afternoon I watched this group of 15 whooper swans fly in to Loch Ederline; this morning I saw them fly off on their spring migration north to their summer breeding grounds. There were a total of around 32 whoopers overnighting on the loch, being given close attention by the resident pair of mute swans.

The flock circled around the village a couple of times and then headed out west towards the sea. There are a number of juveniles in this group of birds.

It won’t be long now before the incoming migrants, ospreys, swallows and martens return from lower latitudes. Spring’s finally around the corner.
