Leave no line behind. If you’re an angler, adopting that practice can be a lifesaver for wildlife.

Fishing line that’s not discarded properly can pose problems for animals, and particularly birds. Entanglement can cause stress, injuries and even death.

One incident that fortunately ended well last year involved a long piece of fishing line that bluebirds used in building a nest at DNR’s Social Circle offices.

Wildlife biologist Anna Yellin spotted the line poking out of the nest box. Fearing that the adult birds or chicks would become tangled, Yellin discussed what to do with DNR ornithologist and Program Manager Dr. Bob Sargent, and then worked with another employee to carefully remove the line.

“It was an awfully big piece for such a little bird!” she said.

The timing was right. The female had been incubating the eggs long enough that the brief disturbance didn’t prompt her to abandon the nest. And from the parents’ behavior, it seems the eggs hatched and the young fledged.

Here’s more from Audubon, plus details on recycling fishing line. (Note: Some DNR boat ramps and Public Fishing Areas include PVC receptacles for recycling line.)
