The Landcare Research Garden Bird Survey (July 2007) measured the number of birds in gardens but also the distribution of those birds across all gardens. They found that:
Blackbirds were the most widely distributed species, being present in 90% of home gardens, followed by house sparrows in 86%, silvereyes 81%, starlings
61%, song thrushes 52%, and other species less than 50% of home gardens.
This is very similar to the results we had with our five brave participants. We could've saved them a lot of money. But the folks at Landcare Research are planning another poll in July so we'll have another chance to make our votes count.
