Near me in the east riding of yorkshire we normally get the first visitors arrive around the 9th of april, last year was the 21st and 2019 the first was the 23rd.
Numbers normally start to grow rapidly into a good sized community of swallows and martins......so far though there are so few i can count them on two hands....
Have others seen similar....could it be that the birds that normally come to my area have had a problem on the migration, or is there a general poor migration number this year?
