When I sow my lawn, why do I have every bird in my neighborhood decide to party on the patch that has just been sown?

• Even though lawn seed has a bird deterrent, there is no stopping hungry birds.
• Some suggestions to deter them are to put string over the area with humming tape or shiny flappy objects to scare them off.
• Vineyards use large blow up owls with huge eyes that can be placed on a stake to scare birds away, they are available from garden centres, hardware stores and rural supplies retailers. 
• Try feeding the birds Tui Wild Bird seed in another area of the garden so that they don't need to feed on the lawn seed.
• Pegging shade cloth or frost cloth over the area will help the seed germinate and keep the birds away.
• Remove the cloth once the seed germinates.
