I have not strayed for bugs in my garden for 31 years. I have 23 bird houses in my back yard near the garden. Most of the bird houses are for Wrens. Wrens eat their weight in bugs every day. I have 1 Blue Bird house. I have 1 Ever Green tree for the Red Birds to nest in. The Red Birds also like to nest in the Blackberries. I keep a 25 watt light bulb ON all night long to attract bugs for the Bats to eat. After dark the Bats come and they ear the bugs that swarm around the light bulb. Bats eat twice their weight in bugs every night.
Here is momma Wren feeding 3 baby birds.
