Venture out of your comfort zone a little. Try one of the following:
1) Go along on a bird walk/hike with a local bird group,
2) Go on an early morning or evening bird walk,
3) go to a completely different habitat,
4) alter the habitat at your current location.
Renting a backhoe and doing major landscape work, change something simple. If you are watching your backyard, change the location of your birdfeeder, or change the color of the birdfeeder, or try a different food source.
