A bird cage with dimensions of 77x46x177 cm is very spacious and suitable for larger birds or multiple small to medium-sized birds, such as cockatiels, conures, or small parrots. Here are some tips for setting it up:

1. Perches: Install multiple perches at different heights and locations to encourage climbing and movement. Vary the materials and diameters to promote foot health.

2. Toys and Enrichment: Provide a range of toys, including foraging toys, swings, and interactive items to keep your birds mentally stimulated and entertained.

3. Feeding Stations: Set up several food and water dishes at different heights. This encourages exploration and helps keep the cage engaging.

4. Hiding Spots: Include small shelters or covers where your birds can retreat to feel safe and secure.

5. Cleaning: Choose a cage with a removable tray and easy-access doors for hassle-free cleaning. Regular maintenance is key to a healthy environment.

6. Proper Placement: Place the cage in a well-lit area with good ventilation but avoid direct sunlight for long periods to prevent overheating.

7. Companionship: If housing multiple birds, ensure they are compatible to prevent any aggressive behavior.
