Parrots: Why They’re an Invasive Species

Like other invasive species, they put native ecosystems at risk and can cause public health problems.

Parrots came to our country to visit. In recent years there have been significant increase in the presence of these birds in parks and gardens, even to the point of overpopulation. Research by the Spanish Ornithological Society estimates that there are about A circulation of 27,000 copies is distributed throughout the country.although the centers of the greatest concentration of this species of birds are the cities of Madrid and Barcelona, ​​where more than half of the parrots settled in Spain live.

The main characters of this occupation are two specific species: Kramer’s parrot and Argentine parrot. Belonging to the parrot family, they are native to Latin America. Physically, they are characterized by a green plumage color with bluish tones on the wings and grayish tones on the front of the body, as well as a long and pronounced tail. They feed mainly on seeds and insects and build their nests cooperatively because they are birds that they tend to live in groups. This shows its colonization potential, which eventually threatened the survival of many native species and created serious problems for the farmers’ union.

Parrots, an invasive species

The uncontrolled overpopulation of parrots is an indication that pose a threat to local flora and fauna. While the number of these birds in our country has increased, the number of specimens of other bird species has decreased. In this case, ecosystems as a whole were affected. Parrots appeared in Spain in the late 1980s, when it became popular to keep this species as a pet. Those parrots that were abandoned have adapted to the wild in habitats other than their own, and they multiplied excessively until I find myself in the current situation.

Since they are non-native creatures, i.e. they They are born and develop in areas far from their original location., they coexist with other species and destabilize the balance of the ecosystem into which they were introduced. They thus influenced other species as they consumed their main food sources, especially colonies of sparrows, blackbirds and magpies, which they eventually displaced. It’s not just like that adapt very easily to a new climate which identifies the single factor that led to the parrot invasion. His high reproduction rate was another reason, along with absence of predatorswhich contributed to its spread.

These birds tend to sing very loudly, which can be annoying.These birds tend to sing very loudly, which can be annoying.

But the consequences of this plague They also influenced people, who sent complaints to various city councils about the nuisance caused by the loud singing of these birds. Loss of native diversity is one of the most striking results of invasive species. They not only lead to the degradation of the ecosystems they invade, but also have an impact on other areas such as e.g. economic losses what they mean for farmers and ranchers who see their crops suffer, or public health issuesas it is possible that invasive species carry unknown diseases.

Parrot Pest Control

The emergence of parrots had repercussions on the national stage to such an extent that the government in 2011 ruled that these birds were an invasive alien species.. Thus, its commercialization was banned to try to reduce the impact it had on ecosystems. Since then, a government decree obliges administrations take action on thisregulating the size and size of parrot populations to prevent their spread, and even allowing the execution of these animals.

In Madrid, concern is growing due to a massive increase in the parrot population. Half of these birds are registered in the capital who live in our country, therefore the dangers and damage, such as noise and dirt, that these animals create are even greater and have become genuine problems of coexistence with neighbors.

Ultimately, autonomous communities must take appropriate measures to eradicate these exotic birds. The procedure is that, firstly, city ​​councils find sources where the greatest incidence of disease is observed, so that later the autonomous government acts through nest removal parrots After this, we must continue to monitor these birds because they will most likely return and build new nests on top of the ones previously destroyed. For this reason, many experts believe that the final solution is to catch the parrots and remove them from the site.

Autonomous communities are responsible for destroying parrot nests to keep the species under control.Autonomous communities are responsible for destroying parrot nests to keep the species under control.

City councils such as Barcelona have created nest removal protocols, which makes it possible to subsequently transfer captured parrots to centers for the rehabilitation and restoration of exotic species. Something similar is happening with the Madrid Council, which solves the problem through catching adults and isolating them in specialized places to prevent their reproduction. Other actions that are also effective: remove parrot eggs during the egg-laying period, which usually lasts throughout the spring and which cuts off the reproduction of these birds in the bud.

Diseases caused by parrots

The parrot invasion has caused problems not only in the ecosystems and other species with which they coexist. Also have had an impact on collective health issues, as they are considered potential carriers of disease. Research shows that these bird species affect human health as we can develop diseases such as pneumonitisin which the lungs are affected due to inhalation of small feather particles, or psittacosiswhich causes fever in infected people by inhaling the feces of these birds.
