Swift update - 16th April 2011

• My sister tells me the swifts are in Paris! Last year they arrived in Paris three days later (on the 19th).
• Last year it took the advance parties four days to get from Paris to Berkshire -they arrived on 23rd.
• Does this mean my favourite birds will be back with us in four days only - ie on the 20th April?
• We're nearly there......!
• EDIT - I now understand that the swifts my sister reported actually were in the Loire valley (not Paris) on the 16th. They actually arrived in Paris on the 20th - a day later than last year...
