Spring - NOT amateur radio

Tomorrow is the first day of meteorological spring. 

I always look forward to the first swallows returning from Africa on migration. They usually arrive here in mid April, although they are a bit earlier in Devon.  Swifts, that we see more of, arrive about mid-May. These are often heard screaming before being seen.

The first to arrive in Devon are the sand martins, which usually are seen in Devon mid March. I recall my dad telling me when he first saw some on his golf course.
