Common ravens (Corvus corax) are found on Long Island, marking a significant return after a long absence. Their re-establishment is a recent development, reflecting ecological changes and conservation successes. These adaptable birds are now establishing a foothold in various habitats across Long Island.
The Return of Ravens to Long Island
Historically, common ravens were widespread across North America, including Long Island. However, habitat destruction and human persecution led to their decline and extirpation from many eastern regions, including New York State and Long Island. Their absence persisted for decades.
The re-establishment of raven populations on Long Island is part of a broader comeback across the northeastern United States. This resurgence is attributed to factors like forest regrowth and increased environmental protections. Ravens are highly adaptable, thriving in diverse environments from wilderness to suburban fringes, where food sources are available.
On Long Island, ravens are increasingly observed in diverse habitats, though less numerous than American crows. They favor woodlands for nesting and open spaces for foraging. Sightings are frequent in parks, nature preserves, and coastal areas, where they find carrion, small animals, and human food sources.
While their population on Long Island is growing, ravens remain less common than American crows. Their presence indicates a healthy, recovering ecosystem. Observations suggest a gradual expansion of their range and an increase in breeding pairs across the island.
Telling Ravens Apart from Crows
Distinguishing common ravens from American crows can be challenging, as both are large, black birds. However, key characteristics help identify them. Ravens are noticeably larger and heavier-bodied than crows, with a wingspan exceeding 4 feet compared to a crow’s typical 3-foot span.
Ravens possess a thicker, deeper, and more robust beak with a prominent arch, while a crow’s beak is smaller and more slender. In flight, the shape of the tail feathers is a reliable clue. Ravens display a wedge-shaped or diamond-shaped tail, whereas crows have a fan-shaped or rounded tail.
Their flight patterns also differ. Ravens are known for graceful, powerful flight, often soaring on thermal currents with less flapping. Crows’ flight is characterized by more continuous and rapid wingbeats. This soaring behavior is rarely seen in American crows.
Vocalizations offer another distinct way to differentiate the two species. Ravens produce deep, resonant croaks, gurgles, and bell-like sounds. In contrast, American crows are known for their familiar, harsh “caw-caw” calls, which are higher-pitched and less varied than raven vocalizations.
