1. *Calcium Source:* The inclusion of calcium in the perch is a positive feature. Calcium is essential for maintaining strong bones and beaks in birds. It can be especially beneficial for birds with high calcium needs, such as certain species that lay eggs.

2. *Size and Shape:* The dimensions of 3.8x17cm suggest a perch that is relatively compact and may be suitable for smaller bird species. The ground shape may appeal to birds that prefer perching lower in their environment or like a broader surface.

3. *Environmental Enrichment:* Having a variety of perch shapes and textures in the cage promotes environmental enrichment. Birds enjoy exploring different surfaces, and the ground-shaped perch can add diversity to their surroundings.

4. *Easy Access:* Birds that may have difficulty flying or prefer staying close to the ground can benefit from a lower perch. It provides easy access for birds to move around and interact with their surroundings.

5. *Maintenance:* Consideration should be given to the ease of cleaning. Ground-level perches might be more prone to soiling, so regular cleaning is essential for maintaining hygiene.

6. *Species-Specific Needs:* The suitability of this perch depends on the specific bird species. Some birds naturally prefer lower perches, while others may prefer higher vantage points. Understanding the preferences and behaviors of your particular bird is crucial.

It's important to monitor your bird's behavior to ensure the perch meets its needs. Additionally, providing a variety of perch types and sizes within the cage offers a more enriched environment. Always consult with avian experts or veterinarians for guidance on the specific needs of your bird species.
