Common Grackle (Quiscalus quiscula) lives in open fields across North America. It feeds on insects and seeds. Its conservation status is Near Threatened.

A real field recording of the Common Grackle, made in the wild.
Adult common grackles stretch from 28 to 34 cm (11 to 13 in) long, with wings spanning 36-46 cm (14-18 in) and a weight that ranges between 74 and 142 g (2.6-5.0 oz). Males tip the scale at an average 122 g (4.3 oz) while females average only 94 g (3.3 oz).
Since the last glacial maximum about 22,000 years ago, the common grackle's range has ballooned to more than three times its former size across eastern North America. Warmer annual mean temperatures are associated with the bird readily colonising open and semi-open habitats. This rapid expansion shows the species' uncanny ability to exploit human-altered landscapes, from farmland to suburban parks. By thriving where forests were cleared, grackles illustrate how climate and land-use change can reshape bird distributions in just a few millennia.
A magnetite deposit sits in the head and neck of common grackle, hinting that they can sense Earth's magnetic field. Researchers have found this magnetic material and suggest it may help the birds navigate. Such a sensory edge underscores how even common species harbour sophisticated, hidden adaptations.
Grackle nests hold between four and seven eggs, most often five or six, and the female sits on them for 12 to 14 days. Once hatched, chicks fledge after about 12 to 15 days but linger near the nest for another day or two, still being fed by parents. Roughly half of the males stay after hatching, helping to feed the young.
A 2011 Audubon analysis of Christmas Bird Count data showed the common grackle's numbers fell 61 % to 73 million birds, down from historic peaks exceeding 190 million. This sharp drop pushed the species onto the IUCN's Near-Threatened list, reminding us that population health must be monitored even for species that seem ubiquitous.

In the lush wetlands and sun-drenched fields, the Common Grackle dances with an air of mysterious elegance, its iridescent feathers glimmering like polished onyx as it moves with a fluid, almost serpentine grace. With each step, its long, keel-shaped tail feathers sway behind it like a banner, as if proclaiming its presence to the world, and yet, despite its striking appearance, the grackle's numbers are dwindling, its future hanging precariously in the balance. As it takes to the skies, its wings beating in a slow, hypnotic rhythm, the grackle's very existence seems a poignant reminder of the fragility and beauty of the natural world.
