The Common Grackle is a species of blackbird found throughout much of North America. They have a shiny, iridescent black body plumage which may shine purple, green or blue in certain light.
Common Grackles are omnivorous, taking prey from insects to small fish and frogs, as well as seeds, berries, and other plant material. Common Grackles are gregarious and can be found in large flocks, especially outside of breeding season.
Common Grackles are found in a very large range and as of December 2013 have a conservation status of Least Concern.
Details & Statistics
The Common Grackle is listed as Least Concern on the IUCN Red List and was last assessed in 2012 by BirdLife International. This species has an extremely large range, and hence does not approach the thresholds for Vulnerable under the range size criterion (Extent of Occurrence <20,000 km2 combined with a declining or fluctuating range size, habitat extent/quality, or population size and a small number of locations or severe fragmentation). Despite the fact that the population trend appears to be decreasing, the decline is not believed to be sufficiently rapid to approach the thresholds for Vulnerable under the population trend criterion (>30% decline over ten years or three generations). The population size is extremely large, and hence does not approach the thresholds for Vulnerable under the population size criterion (<10,000 mature individuals with a continuing decline estimated to be >10% in ten years or three generations, or with a specified population structure). For these reasons the species is evaluated as Least Concern.
