Birdwatching puzzles

A birdwatcher wants to take a walk through her garden and see some of the wonderfully colored birds that frequent it. She likes to enter the garden on the left and exit on the right, not retracing any portion of her walk. And she likes to see the same number of every colored bird. Can you help her find the right route through her garden? Each puzzle has a unique solution.
