I have several types of Amazon parrots and I agree they are not a recommended pet for everyone. I do not encourage people with small children to purchase an Amazon due to the aggressive behavior Amazons can exhibit when they mature. As you mentioned Amazons usually bond with one member of the family so a family with children cannot devote the time needed to ensure the Amazon parrot becomes a part of the family environment.
Many breeders of Amazon parrots are selling out their birds because of the low marketability of the birds. We are seeing a decline in many of the used-to-be common species of Amazons, such as the Red Lored, Spectacled (White-fronted) and Orange winged Amazon. I fear that many of the Amazon species are going to become rare in captivity here in the U.S. as breeding stock dies out.
Most of the Amazons were imported into the U.S. during the 70s and 80s. People who acquired these Amazons as pets back then usually keep them in the family for quite a while (30 to 40 years) as these birds are great talkers. Sadly many of these Amazon parrots are sitting in a small parrot cage and never get out to spread their wings as the saying goes. Even with what most believe is poor quality of life, these Amazons are living into their 50s.
The groups of Amazons we have truly enjoy a rainy day – they spread their wings and take full advantage of a good bath, yelling and flapping their wings for 15 minutes or more. That’s about types of Amazon parrots and great fun to watch them.
