The sabian symbols divide the zodiac into incriments of one symbol for each of the 360 degrees. there are lots of symbols dealing with birds.
Here are some that come to mind. (Shortened versions from Dane Rudhyar's "An Astrological Mandala")

Because the symbols read from 1-30 rather than 0-29, make sure to read the symbol for the next degree up. for instance a planet at 0.23 aries should be read as 1 aries, 1.07 as 2 aries, etc.
