The "5 7 9 rule" is a guideline used by some wildlife enthusiasts to estimate a squirrel’s age based on its tail and body development. Here’s a quick breakdown:

• 5 weeks: Squirrels start to develop fur on their tails.
• 7 weeks: Their tails become bushier, and they’re more active.
• 9 weeks: Squirrels are usually fully furred and ready to explore outside the nest.

This rule is mostly used by wildlife rehabilitators. For backyard squirrel watching, it’s just a fun way to understand their growth stages as you spot them at your feeder.

Offering corn to squirrels can be a fun way to attract them to your yard, but it’s best used as an occasional treat rather than their main food source. Corn is high in sugar and low in essential nutrients, so balance it with other foods like nuts and seeds. If you use a corn cob holder or squirrel picnic table feeder, make sure to clean it regularly to prevent mold. Always provide fresh water nearby and avoid processed or salted corn for the healthiest squirrel visitors.

Squirrels are known for their sharp memories, especially when it comes to food sources. If you consistently put out food using a squirrel feeder, they may start to associate you or your yard with snacks. Some squirrels can even recognize regular feeders by sight or sound. While they won’t become pets, you might notice them waiting nearby when you refill the feeder or becoming less shy over time.

In October, squirrels are busy preparing for colder weather. You’ll often see them gathering and storing food like corn, nuts, and seeds in various hiding spots. This behavior, called "caching," helps them survive when food is scarce in winter. Squirrels may visit feeders more often during this time, so keeping your squirrel corn feeder stocked can support their natural habits and give you plenty of backyard entertainment.

Keeping your squirrel feeder clean helps prevent mold, bacteria, and unwanted pests. Here’s how:

1. Empty out old or wet food regularly.
2. Wash the feeder with warm, soapy water every week or two.
3. Rinse thoroughly and let it dry before refilling.
4. Check for any signs of damage or sharp edges that could harm wildlife.

Staying on top of cleaning keeps your feeder inviting for squirrels and helps maintain a healthy backyard environment.
