The Invisible Rut: Understanding and Hunting During the Secondary Rut

The primary rut, often referred to as “the rut,” is a well-known and eagerly anticipated period for deer hunters. However, not as many hunters are aware of the secondary rut, also known as the “invisible rut.” This lesser-known phase offers unique hunting opportunities that can lead to successful and memorable hunts. In this guide, we’ll explore what the secondary rut is, why it occurs, and how you can take advantage of this period for a productive hunting season.

What is the Secondary Rut?

The secondary rut occurs a few weeks after the primary rut and is characterized by a second, smaller peak in breeding activity. This period typically happens in mid to late December but can vary depending on the region and local deer population dynamics.

Why Does the Secondary Rut Occur?

The secondary rut happens because some does were not successfully bred during the primary rut. These does will come into estrus again approximately 28 days later, triggering another round of breeding activity among bucks. Younger does born in the spring may also reach sexual maturity and come into estrus for the first time during this period, contributing to the secondary rut.

Understanding Deer Behavior During the Secondary Rut

Buck Activity

• Renewed Searching: Bucks that were unsuccessful in breeding during the primary rut will begin searching for the does in estrus again. Their movement patterns will increase as they cover more ground.
• Territorial Behavior: Bucks may revisit and freshen up scrapes and rubs to mark their presence and attract estrous does.
• Reduced Competition: The number of bucks actively seeking does will be lower than during the primary rut, reducing competition but also requiring more effort to locate active areas.

Doe Activity

• Estrus Cycles: Does coming into estrus during the secondary rut will behave similarly to those during the primary rut, showing signs of readiness to breed and attracting bucks.

Hunting Strategies for the Secondary Rut

1. Focus on Food Sources

During the secondary rut, food sources become increasingly important as deer try to regain energy lost during the primary rut. Key food sources include:

• Agricultural Fields: Corn, soybeans, and winter wheat fields are prime spots.
• Natural Browse: Areas with abundant natural browse like acorns, berries, and other vegetation.

Set up stands or blinds near these food sources to intercept bucks checking for estrous does.

2. Monitor and Freshen Scrapes

Scrapes that were heavily used during the primary rut can become active again. Check these scrapes for fresh signs of activity and consider using mock scrapes to attract bucks.

• Fresh Urine: Use doe-in-estrus urine or buck urine to freshen up scrapes.
• Scent Drippers: Place scent drippers over scrapes to maintain their attractiveness over several days.

3. Use Estrous Calls and Lures

Estrous calls and lures can be highly effective during the secondary rut, attracting bucks that are actively searching for does.

• Estrous Bleats: Use doe estrous bleats to mimic the sounds of a doe in heat.
• Rattling and Grunting: Simulate buck fights and vocalizations to draw in bucks curious about potential rivals or breeding opportunities.

4. Hunt Travel Corridors

Deer will use established travel corridors between bedding areas and food sources. These areas can see increased activity as bucks move through them while searching for estrous does.

• Funnels and Pinch Points: Narrow travel routes that deer naturally funnel through are prime locations.
• Ridges and Saddles: Elevated areas that offer easy travel routes for deer.

5. Be Prepared for Cold Weather

The secondary rut often coincides with colder weather, which can influence deer movement and behavior. Be prepared for cold weather hunting by dressing in layers and using proper gear to stay warm and comfortable.

• Warm Clothing: Wear insulated, moisture-wicking layers to stay warm and dry.
• Portable Heaters: Use portable heaters in blinds or stands if necessary.

Conclusion

The secondary rut, or invisible rut, offers a valuable opportunity for hunters to capitalize on another wave of deer breeding activity. By understanding the behavior of deer during this period and implementing effective hunting strategies, you can increase your chances of success. Focus on key food sources, monitor scrapes, use estrous calls and lures, hunt travel corridors, and be prepared for cold weather conditions. With the right approach, the secondary rut can be a rewarding and productive time in the deer hunting season.

Happy hunting and good luck!
