Birds have a fascinating way of managing their digestive process. Grit, small particles of stone or sand, plays a crucial role in aiding their digestion. When birds consume grit, it’s stored in their gizzards, where it collaborates with the organ to break down tough foods that are otherwise challenging to digest. This unique mechanism enables birds to extract maximum nutrition and energy from their meals, ensuring they stay fueled and energized throughout the day.

How Do Birds Digest Grit?

Birds have developed a fascinating mechanism to aid in their digestion process called grit digestion. Grit, such as small stones or gravel, plays a crucial role in this process. Rather than simply grinding up the food they consume, birds store grit in their gizzards. The gizzard, a muscular organ, works in conjunction with the ingested grit to break down hard-to-digest foods.

The Different Types of Grit That Birds Consume

  • Small pebbles
  • Sand
  • Gravel
  • Crushed eggshells
  • Seashells
  • Charcoal
  • Coral
  • Mineral rocks
  • Oyster shells

Similarly, if your walls have cracks or crevices, birds may be pecking at them to access hidden food sources like spiders or small insects. Additionally, some birds may peck at walls as a way to communicate with other birds, establish territory, or attract mates. Understanding the reasons behind this behavior can help homeowners take appropriate measures to prevent damage while still accommodating these curious creatures.

Why Do Birds Peck at Walls?

Woodpeckers, in particular, have strong beaks and specialized tongues that allow them to extract insects from the crevices of wooden surfaces. They may also be attracted to the sound produced by pecking on walls, as it can mimic the sound of insects or drumming to establish territory.

Other birds, such as sparrows or finches, may peck at walls in search of seeds or berries that may have become trapped or lodged in small cracks. These small openings can provide a convenient food source, especially during times when natural food supplies are limited.

In some cases, birds may peck at walls as a form of communication or territorial behavior. By drumming and pecking on a hollow surface, they can produce loud sounds that carry over long distances.
