A few days ago I saw my first house martins this year in the UK. This is much later than usual, so I wonder if numbers are down? These were in a nearby village. I've seen none in our village this year.
There seem to be plenty of swifts - there were about 20 feeding overhead last evening - but house martins and swallows seem to be fewer this year. This may be a localised thing, but I notice numbers seem down.
Anyone know the facts?
