What Do Macaws Eat? – The Natural Diet

The beak of a macaw is hard enough to crack open various nuts. These birds do so by putting a lot of pressure on their facial muscles. The strong beak and big tongue allow them to pull the seeds out of their nutshells.

Wild macaws also eat flowers and their nectar by sucking on the succulent portions of plants. Similarly, berries, eggs, and various insects make up their daily diet. Snails are another source of calcium for wild snails.

As macaws are inhabitant of rainforests, ample amount of vegetation is available for them. This includes flower buds, leaves, and other parts. Macaws are also known to show another type of interesting wild behavior called geophagy.

It means that macaws also eat clay and dirt to keep their digestion running. Research suggests that eating clay protects macaws from various toxins present in their feed. Many plants in the wild rainforests contain toxins that are detrimental to macaws’ health.

The clay provides a medium to neutralize the present toxins. It works like activated charcoal that binds with the toxic substances inside the gut and neutralizes them. At the same time, the clay also provides mineral content such as calcium, phosphorous, and carbonates.

Importance of Nutrition for Macaws

Most bird owners think feeding the regular bird diet to every pet bird is enough. This is not true as different organisms need different diet plans. Instead of focusing on a diet just to maintain life, pay attention to the actual diet of macaws.

The provision of proper nutritional content to macaws benefits them in several ways. The food you offer must be nutritionally balanced enough to help your macaw flourish. You may hear the common saying that the bird’s health is entirely dependent on the type of diet.

Nutrition might sound like a common word but the life of macaws depends on it. Feeding macaws with well-balanced nutrition keep them disease free and strengthens their immune system. In contrast to other parrots, macaws have considerable body size and mass-to-bone ratio.

A fully formulated diet of macaws includes an appropriate amount of carbs, proteins, and fats. Minerals and vitamins are equally important as they help maintain the metabolism. Just as carbs and fats act like energy reserves, proteins are vital for the macaw’s growth and weight.

Both wild and captive macaws have almost similar nutritional needs. To maintain consistency in nutrition, you must follow proper macaws feeding guidelines. Keep reading to find out what are the diet options in the case of these beautiful macaws.

Ideal Diet Regimen for Macaws

If you’ve come to this point, it seems like you are planning to get a macaw or are confused about its feed. Macaws need a wholesome diet that you can easily make at home. Just like the pelleted diet of other pets, there are many commercially available macaws’ feeds.

According to birds’ nutritionists, a good ratio of 75% pellets and 25% natural source is ideal. The major portion of the all-natural diet contains seeds and other vegetation. In that essence, these are the following feed inclusions in the case of macaws.

  • Nuts & Seeds
  • Pellet Feed
  • Fruits & Veggies

Let’s talk about how well these ingredients are in terms of nutrition provided in the case of macaws.

Nuts & Seed

Nuts and seeds contain a majority of the beneficial nutrients for macaws. These are the main diet source you can provide. However, one thing I must mention is that nuts and seeds should never be fed as the only source of diet in macaws.

The reason is that they are fat-rich and cause dietary intolerance in large amounts. This is why seeds and nuts must be offered along with other nutrients. It is recommended that include a couple of nuts per day mixed with other feed.

If you’re concerned about which seeds and nuts are suitable for macaws, you’re not alone. In the case of nuts, you can use peanuts, cashews, almonds, and hazelnuts. These are completely safe for macaws and don’t carry any harm when fed in appropriate quantities.

Canary, buckwheat, oats, and millets are preferred and frequently used in macaws. Most of the macaw owners also choose sunflower seeds in their diet. But, the problem with sunflower seeds is that they are high in fat and prolonged use may cause digestive and weight issues.

Pellet Feed – The Complete Nutrition

In the modern animal nutritional sector, pelleted diets are a preferable option to choose from. Pellets are made by grinding the basic feed ingredients into a palatable format. If your macaw is on a seed diet, changing that to a pellet one is highly recommended.

In short, pellet feed is a must and ideal choice for macaws. Pellet manufacturers produce several different types of pellets for individual bird needs. For instance, if the macaw is deficient in protein requirements, you can get one with a high crude protein percentage.

It takes almost 4 to 6 weeks for a seed-fed macaw to shift toward a pellet diet. You can improve the pellet acceptance by mixing small amounts into the regular seed mix. Then gradually start reducing the quantity of the seed and increase the pellets at the same time.

You may think of stopping the seeds entirely before shifting towards the pellet. This is not beneficial at all because such sudden changes can lead to gut upset in macaws. The transition should be done slowly and consistently.

Once you offer the pellet diet with seeds, always make sure the macaw is eating that mix. Some macaws are stubborn and they start sorting out the feed and ignore the pellets. But, you can train your macaw to eat pellets with a diet without exerting any stress on its gut.

What About Vegetables & Fruits for Macaws?

Many new macaw owners choose green leafy vegetables for macaws thinking these are good for them. Vegetables such as celery and lettuce have high moisture and water content. Besides, these vegetables don’t contain any appreciable amount of nutrition in them.

Apart from seeds, nuts, and pellets, fruits and vegetables make up 20% to 25% of the feed. You can grow different vegetables in your backyard or purchase them from the supermarket. In case you buy them from a store, certain measures must be taken before provision to macaws.

Store-bought fruits and vegetables have many chemicals such as herbicides and pesticides. These chemicals possess detrimental effects on the health of macaws. Therefore, you must wash them under running water thoroughly to remove all types of harmful agents.

Sometimes, macaws develop the habit of eating only one to two types of vegetables or fruits. You must limit the respective quantities so that the macaws don’t eat them often. In the case of vegetables, you can try zucchini, carrots, beets, broccoli & pumpkin.

Fruits, although nutritious, contain a high amount of sugar in them. In the case of macaws, fruits must be supplied in limited quantities. The high sugar content will make the intestines runny leading to diarrhea in macaws.

The inclusion of fruits in the macaw’s diet plan should be done on an occasional basis. There is no need to provide fruits every day in large quantities. You can reduce the size by cutting the fruits into small pieces and using different trays for fruits and vegetables.

Additional Tips Related to Macaws Foods
