Procnias nudicollis is known from a wide area of east Brazil (Alagoas south to Rio Grande do Sul and inland to south Mato Grosso), north-east Argentina (Misiones, with one record in Corrientes) and east Paraguay (west to Concepción) (Ridgely and Tudor 1994, Parker et al. 1996, Bertonatti 1997). The combination of increased rates of habitat loss and more intense trapping pressures within this species's range in Paraguay and Brazil mean that its population is likely to have been undergoing rapid declines. For these reasons the species qualifies as Vulnerable.
The Burrowing Owl (Athene cunicularia) is a species from the Strigidae family. It is an owl with about 23cm, and can be found throughout open landscapes from North to South America. Burrowing Owls can be found in grasslands, rangelands, agricultural areas, deserts, or any other open dry area with low vegetation.In Brazil, it is a very common species, very easy to find on grass areas, even inside the cities.Burrowing Owls are very active during the day.
This species has been uplisted to Vulnerable because it is suspected to have undergone rapid declines during the past three generations (56 years) owing to deliberate and incidental poisoning, habitat loss, reduction in available prey, pollution and collisions with power lines. Further information on trends across its large range may lead to its further uplisting to Endangered in the future.
