Some seasonal fluctuations in bird numbers are apparent. Fewer birds were seen in July and August compared with other times of the year, although there is considerable variation in bird numbers in, any one month, for example the daily count of birds during March, 1980, varied between 12 and 800 birds. The maximum number of approximately 1000 birds was recorded during April and May, 1980 (which coincided with a period of heavy rain which washes the pollen and nectar out of flowers, the usual food E 600 5 400 - {.
