What has happened to the flights of migratory birds swallows and similar we used to enjoy watching?

Until recently there were large flights of around our area but last year there was one solitary swallow – and this year none.

There has been no extensive loss of habitat here.

Do we blame the wretched so-called hunters of southern European countries and Malta, or climate change?

Certainly the weather this year might be a reason – but previously when have there been bad years?
