I am not sure if it is still the case, but come the season of Spring to England, a letter would be published in The Times informing the readers of a sighting of the first cuckoo for the year. (Wonder where they winter? Costa del Sol?)
Come Autumn in Australia my favourite spotting distraction is watching or listening to the media for the first mention of an INDIAN SUMMER. Last night a television weather presenter announced we are now having an Indian Summer. He is possibly correct but in years past the definition has been applied very loosely. Two warm and sunny days do not an Indian Summer make, besides, successive days of 30 degrees is rather more like a normal summer and given we have not reached the Autumn Equinox, it really is still summer.
