House sparrows are the most common birds in New Zealand gardens, according to a preliminary report on the second stocktake of garden birds.
More than 2,000 people spent an hour noting the greatest number of each species they saw or heard at any one time in mid-July.
The head of the bird survey, Eric Spurr, says this year's count suggests silver eye numbers are slightly down while house sparrow tallies are slightly up.
Silver eyes, also known as wax eyes, topped last year's count.
But Dr Spurr says the survey needs to be repeated annually at least three more times for more meaningful results.
