- Sound of the Burrowing Parakeet.
The species usually inhabit areas open pastures, although it has also been reported in Savanna, wooded valleys cliffs and farmland some 2.000 m. Usually in a fairly arid land, although often it found near elevations or streams. Gregarious, forming large flocks, sometimes exceeding 1.000 birds, with common roosts trees, on wiring (sometimes in villages) and tunnels dug to nest.
It reproduces colonially in warrens carved into cliffs (usually limestone or sandstone Chile) often with stunning views. In San Luis, Argentina, reproduction is reported in the wet season (November–April), the birds return to nest in the cliffs lay eggs in September and November to December in San Luis, spreading of bird breeding sites in April; apparently earlier in Chile. Clutch 2-4 eggs. The male takes care of feeding the female during the incubation period. The young leave the nest to 2 months of age, However, They continue to be fed by their parents until 6 months of age.
The diet of the Burrowing Parakeet It consists mainly of seeds and fruits predominance of fruit in the summer months (November to February). Food reported include berries of buckthorn joke and Discaria, fruit of Geoffroea decorticans, Prosopis caldenia, P. chilensis and P. flexuosa and seeds of Carduus mariana. Sometimes damaged grain crops; often it feeds on the floor or around.
Extensión de su área de distribución (cría/residente): 1.590.000 km2
The Burrowing Parakeet They are distributed by the South South America, extending from northern Santa Cruz and Chubut in Argentina, passing by Rio Negro and Pampa, up to Buenos Aires, San Luis and Córdoba, San Juan, La Rioja, Catamarca, Tucumán and Salta, reaching westward across southern Uruguay.
They were recorded in the early 1920 from the center of Formosa, Argentina, away from Andes mountains, and above the center Chile from the North of The lakes to north of Atacama, but now they are confined to a few localities in the foothills of the Andes, for example in Bio Bio.
Will produce some seasonal movements, including the northward migration of birds south in the Argentine winter and shifts down Chile.
In Argentina It is locally common or abundant, although in some places (p. e.g.. in Córdoba and Buenos Aires Eastern) They are rare or occasional. Few and far between in Uruguay. drastic decline during the twentieth century Chile, so that the subspecies Cyanoliseus patagonus bloxami It is considered at risk, with an estimated population of less than 3.000 individuals at the end of the decade 1980. The decrease in parts of the Argentina It is attributed to the catch for the trade, the hunting for food, converting grassland and arable land persecution as crop pest. Probably continues to decline overall.
• Current red list category of the UICN: Least concern.
• Population trend: Decreasing.
• Population size : 95000 individuals.
Justification of the red list category
Although the demographic trend It appears to be declining, It not believed to be declining fast enough to approach the thresholds for Vulnerable at the discretion of the demographic trend (> 30% decrease in ten years or three generations). The population size is very large, and therefore does not approach the thresholds for Vulnerable under the criterion of population size (<10.000 individuos maduros con un descenso continuo estimado en >10% in ten years or three generations, or specific population structure). For these reasons, the species is evaluated as Least concern.
Justification of the population
The species is still common in many parts of its range in Argentina, with only small contractions reported in range Córdoba (R. M. Fraga a slightly. 2003). The population size of four subspecies was estimated as follows by MASELLO et al. (2011): Cyanoliseus patagonus patagonus 43.330 nests, Cyanoliseus patagonus conlara 1.700 individuals, Cyanoliseus patagonus andinus 2.000 nests, Cyanoliseus patagonus bloxami 5.000-6.000 individuals. Based on these figures, the population Total overall can be about 95.000 mature individuals.
They suspected that the population is declining due to continuing habitat destruction and unsustainable levels of exploitation.
The species has been the subject of a intense trade: from 1981, year it was included in the Appendix II of the CITES, they have been 122.914 individuals caught in international trade (UNEP-WCMC CITES CITES Trade Database, January 2005).
Conservation actions underway
The species is included in the Appendix II of the CITES.
The average life expectancy is of 15-20 years in captivity. Protected by Appendix II of the CITES.
To help conservation Burrowing Parakeet, You can report your hunt, sale, trade and illegal possession, thus, We will be cooperating with the conservation of this species and not be complicit in the decline of their populations and their future extinction of wild.
