It is true about the old Proverb "One Swallow doesn't make a Summer".
I took this on a day that the temperature had dropped again to about 10 celsius and it certainly didn't feel like Summer.
Obviously its still Spring here and some days its nice weather and some like this day, not so nice.
With the wind chill where I took these images it was more like 7 celsius.
However, it is the first Swallow I have photographed this year and it was sitting quite nicely on a low wire.
