[rec.birds] swallows return to Capistrano

andrewt@cluster.cs.su.oz.au (Andrew Taylor) (03/22/91)

I've just read that 2000 people were in Capistrano to greet the returning
swallows on March 19. Supposedly that have been late only once (in the 1930's).

I'm skeptical the majority arrive on a single date because the calender year
doesn't match the solar year precisely i.e some years the swallows should turn
up on the 18th (or 20th).

Do the majority of the swallows really arrive on March 19?
Why is there return date even close to precise - why don;t they wait
for favourable weather along the way?

A few years ago I was in San Diego for a meeting in EARLY MARCH, and
took a couple of days to drive up the southern Cal coast.  Naturally
I stopped at Capistrano, and there were plenty of swallows all over
the place, swooping in and out of the mission.  I tried to find
someone who could tell me why they had arrived EARLY that year, but
without success.  
I suppose they were the advance guard, and I just don't believe that
they all arrive on the same day.

While waiting for my carpool person I picked up a recent issue
of Westway and it had a small blurb about the swallows returning
to Capistrano and it said they don't always come back on the same
day so the town holds a month long celebration during March.
