| The Lake Erie water snake is also polymorphic, ranging from banded to unbanded gray coloration. |
| This is because scoring of unbanded chromosomes in metaphase preparations to detect aberrations is labor intensive and prone to technical artifacts. |
| If necessary, birds should be released unbanded, or the trapping devices should be temporarily closed. |
| 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. |
| Try to revive and release such birds as quickly as possible, unbanded if necessary. |
| As a general rule, birds should be released unbanded if they have been waiting to be banded for longer than an hour. |
