| However, after previously unbanded birds were banded during nesting, the understanding of territory boundaries and number of territories never changed. |
| If necessary, birds should be released unbanded, or the trapping devices should be temporarily closed. |
| In a swim test in a tank, an Adelie penguin wearing a band expended 24 percent more energy than an unbanded penguin. |
| As a general rule, birds should be released unbanded if they have been waiting to be banded for longer than an hour. |
| Two are unbanded males, and one of these males escapes. |
| Whenever a situation develops in which you cannot safely band the number of birds being caught, you must release some unbanded and close down some or all catching devices. |
