You report on a warning from the Royal Horticultural Society about the effect that the recent exceptionally hot summer has had on plants (14 October). But where have all the garden birds gone? We can usually see finches, jays, wrens, sparrows and robins in our garden, which is full of berries and seeds at this time of year. This autumn there are none. I fear the heat has wiped out a generation of small birds. Is this a problem in other cities?
