Have been wondering about the migratory paths of swallows so I contacted Mothers Garden, Catalonia, Spain by email to ask if there had been a decline in swallows in their area. This is their reply
Nothing has changed – we still have our swallows in the barn and drinking from our reservoir.
They seem as plentiful as ever. Hope this is helpful.
Catalonia is an autonomous region of Spain located on the Mediterranean Sea next to France.
