Hey birds, save some of the garden for me

I was beginning to wonder if I had a soil problem in my garden as a lot of plants were not growning much or even sprouting. Granted my garden soil is still being developed after being treated like dirt for the last thirty years, but I still expected more productivity. It finally occurred to me to cover a batch of seedlings with a variety of covers to see what happened, and sure enough the plants that were covered with nets, spinach plants that went to seed, ... actually grew. Given these covers wouldn't stop mice or slugs it had to be birds. Also given that I have to change the water in the bird bath almost daily points to that I have a lot of bird activity. I don't mind having birds, especially native birds eating in garden but my entire planting of a few crops was eaten by birds.

Because I'm planning on going year round with this garden I going to draw up some plans on ways to keep birds away from the seedlings just using the scrap wood I have around the house.
