I spent Bank Holiday weekend at the Hay Festival, talking to people about nature. Driving home along the borderlands and the North Wales coast, how many Swallows did I see? Four.
Four Swallows in 133 miles at the end of May.
My own experience reflected one of the most common questions from festivalgoers: “Where have all the Swallows/Swifts/House Martins gone?”
But how representative was my journey or the observations of others? BirdTrack, the online database holding lists collected by thousands of birdwatchers, provides some clues.
Compared to the historic average, there were 21% fewer records of Swallows and Swifts in Wales in May, and a whopping 30% fewer House Martins.
House Martins and Swallows are down across Britain and Ireland, though the drop in Wales is far greater.
Swift sightings in Wales are one-third down on last year, but on a par with summer 2017.
It’s difficult to know why, but both weather and food supply play a part. All these birds depend on flying insects, and most surveys of invertebrates point to huge declines across Europe.

What else is around at the moment?
A smart Woodchat Shrike at Cemlyn over the weekend was a rare visitor from the Mediterranean.
It’s been seen only half a dozen times previously on Anglesey , though four of these records are from the Cemlyn area.
This North Wales Wildlife Trust reserve also hosted a Little Stint and a Hen Harrier at the weekend.
A White-winged Black Tern swapped the marshes of southeast Europe for RSPB’s Burton Mere Wetlands on Friday, where three Spoonbills include a nest-building pair.
Last week’s Western Orphean Warbler on Bardsey proved to be a one-day wonder, and a Common Rosefinch was scant compensation for those who missed it.
A Pomarine Skua flew past RSPB South Stack on Sunday, among counts of 1,500 Manx Shearwaters and over 100 Gannets.
