Here is a description of the raven bands we have been using:
We have been banding ravens intensively since 2002, and all ravens banded should have bands on both legs. On the bird's left leg should be an aluminum USGS number band that can usually only be read when the bird is in hand. The color band should be on the bird's right leg. We have used two different types of color bands in a variety of different colors. Here are the details:
Green Anodized Aluminum Bands
Used from 2002-2005 (a few birds prior to 2002)
These bands always have one symbol over another. The top and bottom symbol can be either a number or a letter. Here's an example:
NOTE: We stopped using these because some bands tended to fade. It is possible to see one of these bands without the green. If that is the case, it is next to impossible to read the letters/numbers.
Plastic Bands
Used from 2005-Present. Colors used so far have been yellow, silver, and orange (all with black lettering). The symbols can be confusing at first. We have limited the bands to one symbol/band, and either a letter or number. However, each symbol can be in one of four directions: right-side-up, up-side-down, and turned left or right. Below is a silver plastic band that has an "a" that was turned to the left. If you happen to see a band, just write down what you see in the direction you see it.
