Still waiting - NOT amateur radio

The earliest I have seen a swallow (bird) here is April 7th. It is now April 15th and I have still to see one here. These birds migrate, spending the winter in southern Africa. They fly around 6000 miles back here crossing seas and deserts. Often they come back to the very same nest!  The return of the swallow is an important date in my year. It is a sign that what has happened long before I was around is still going on. I patiently wait.
