What class of animal does a Common grackle belong to?

Common grackles belong to the class Aves, the common class for all types of birds.

How many Common Grackles are there in the world?

Common grackles are present in large numbers in their native range. Currently, their population stands at approximately 69 million adult common grackles. The total number of grackle birds, including the juveniles, has been counted to be around 103.5 million individuals. In the last 40 years, these North American birds have decreased in large numbers throughout their entire range. The population trend in some places of its range at that period declined enough to approach the threshold of a vulnerable species. However, the recent rate of their decrease has slowed down. The lowered annual declines of their population in their range indicate a promising growth of their numbers in the future.

Where does a Common Grackle live?

The common grackle is an endemic bird species of North America. Their range extends from eastern North America, east of the Rockies in the United States to northern and central Canada in the north, and the Gulf of Mexico in the south. Current estimates have shown traces of these North American birds further north in Manitoba, Canada than what was previously assumed. In winter, common grackles move from the north to the southeastern states, except the residential Gulf Coast population. The bronzed common grackles are found in New England, while purple grackles occur from New York to North Carolina and further south in the southeastern states the greenish grackles are found. They stretch from Louisiana to Florida.

What is a Common Grackle's habitat?

Common grackles are found in various types of open habitats. The birds are found to occur in huge numbers around agricultural lands and farms. As a result, agricultural expansion in many areas has benefitted these birds on a large scale. They can also inhabit open marshes, swamps, meadows, and open forest edges. Human-modified lands such as suburban and residential developments, city parks, and cultivated lands and plantations also shelter a large number of common grackles. They build their nests in comparatively private spots, generally among dense trees or in shrubs located near water and low marshes. Some unusual nesting sites have also been located in the bird species like inside woodpecker holes, old buildings and under barns, the lower part of an active osprey nest, and on rafters. Their nest site is bordered with grass, mud, and horsehair.  

Who do Common Grackles live with?

The common grackles are highly social birds. They travel to their migrating grounds in large flocks. These flocks do not only consist of birds of their own type but they also migrate with other species like the red-winged blackbird, European Starling, and Brown-headed Cowbird. Their wintering flocks might consist of more than a million birds. During the breeding season, they have been observed to roost in small to large colonies in their breeding sites. The common grackles in a group are referred to as plague.

How long does a Common Grackle live?

The highest recorded age in the species of common grackles is 22 years. However, most of the birds in the wild do not have such a long lifespan. Only half of their total population can reach adulthood.

How do they reproduce?

The female bird builds a cup-shaped bulky nest before the season using twigs, branches, and leaves. Usually, the common grackles prefer to nest in large coniferous trees with some exceptions. The male fluffs up its feathers and tilts its head backward to show prowess over other male birds and to attract female birds towards it. Copulation in the birds begins as soon as the nest-building process ends. The female lays around 1-7 eggs in a single clutch. Mostly, the male birds isolate the eggs and the nest right after breeding while some stay around with their female partner and take part in incubating the eggs. The common grackle juvenile emerges from the eggs after an incubation period of 12-14 days. Adult common grackle call and displays are common during the incubation period. The young bird fledges the nest after 12-15 days but stays closer to the nest for the next day or two. They are fed by their parents for several weeks. Sometimes, this social bird has been observed to visit a nest and feed other birds' babies.  

What is their conservation status?

The common grackles have been classified as a Near Threatened species in the International Union for Conservation of Nature or the IUCN Red List. Their population has declined in the past few years but human modifications on open lands have gradually helped the birds to restore their numbers. At present, their population trend is monitored and many measures have been taken to stop their decline.
