Tip of the Week:
Many mammals are raising their young on our urban and suburban landscapes at this time of year. This includes squirrels, chipmunks, rabbits, opossum, raccoons, skunks foxes, coyotes, deer, bobcats and bats. Mammals use not only our parks and natural areas, but will also den right in our yards and neighborhoods. Sometimes they get a little too close for comfort utilizing attics and crawl spaces. The following are important tips for coexisting with mammals:
- Never intentionally feed wild mammals. It causes them to lose their instinctual fear of humans and can lead to bigger problems. Although it may seem kind, feeding wild mammals often leads to the kind of conflicts that results in their removal from the environment.
- Enjoy wild mammals from a distance but to not try to approach or tame them down.
- If you find a young mammal, do not assume that it is orphaned. A parent is often close by but may not return until humans leave the immediate area. Before rescuing an animal you think may be orphaned please call our Wildlife Care Center (503-292-0304) for advice.
- Keeps dogs on leash when you visit parks and natural areas (unless it is a designated off-leash areas. Many orphaned mammals are caused by dogs running free in natural areas and disrupting dens and separating young from their parents.
- Close up openings to attics, basements and crawlspaces. Prevent access to indoor spaces is one of the most effective ways to prevent problems.
- Avoid trapping and relocating of wild animals, especially in the spring. Animals often do not survive relocation and at this time of year, it often results in orphans being left behind. If you are having a problem with a wild animal, contact the Portland Audubon Wildlife Care Center (503-292-0304) for advice on how to resolve the conflict or visit our Living with Wildlife page at https://audubonportland.org/our-work/rehabilitate-wildlife/having-a-wildlife-problem/
