The answer to whether Common Ravens inhabit the state is a definitive yes, as Corvus corax is a year-round resident of New Hampshire. These large, intelligent birds successfully recolonized the region after nearly disappearing from the Northeast during the 1800s. Early persecution and extensive forest clearing had pushed the species out of its historic range. However, reforestation and increased protections allowed their population rebound to begin by the mid-20th century, representing a notable conservation success story.
Raven Range in New Hampshire
Common Ravens were historically confined to the rugged, remote landscapes of northern New Hampshire, particularly the White Mountains. They found sanctuary in high elevations and on rocky cliffs. Their initial recolonization efforts, spanning from the 1970s through the 1990s, focused on these traditional mountainous habitats. However, the species has since demonstrated remarkable adaptability, expanding its permanent residency far beyond the northern forests.
The raven’s range now extends across the entire state, including the southeastern third and the seacoast, an area they were once absent from. They seek out diverse habitats, including dense spruce-fir forests, mixed hardwood woodlands, and rocky alpine environments. This expansion has seen them adapt to human-dominated landscapes, utilizing structures in developed southern regions where natural cliffs are scarce. The species is now a regular sight statewide, though they tend to avoid large, densely urbanized centers.
Distinguishing Ravens from Crows
Differentiating a Common Raven from the American Crow requires observing several key physical and behavioral traits. The Common Raven is noticeably larger, averaging 24 to 27 inches in body length, compared to the American Crow’s 17 to 20 inches. This size difference makes the raven comparable to a Red-tailed Hawk, while the crow is closer in size to a pigeon.
A reliable visual cue in flight is the shape of the tail feathers. The raven’s tail appears distinctly wedge- or diamond-shaped when spread because its middle feathers are longer than the outer ones. In contrast, the American Crow’s tail feathers are nearly the same length, giving its spread tail a fan-like or rounded appearance. Ravens also possess a shaggier appearance around the throat, featuring long, pointed feathers called hackles, and they have a much thicker, more robust bill than the crow.
Flight patterns offer another helpful identifier. Ravens are adept at riding thermals and can be seen soaring and gliding for extended periods. Crows, by comparison, typically use a steady, consistent flapping motion for sustained flight. Listening for the bird’s call provides the simplest distinction: ravens produce a deep, resonant, and guttural croak or “cronk” sound. American Crows are known for their louder, more familiar, and higher-pitched “caw-caw” vocalization.
Population Status and Nesting Habits
The population of Common Ravens in New Hampshire is currently stable and increasing, reflecting a significant recovery from their historic decline. This successful rebound is attributed to the regeneration of forest cover and their ability to utilize new food sources and nesting locations provided by the modern environment. Their conservation status is rated as low concern, a testament to their opportunistic nature and intelligence.
Ravens often establish large, bulky stick nests on cliff faces or high ledges, particularly in the northern part of the state. Where natural rock structures are limited, they construct nests high up in tall trees, usually conifers. As their range expanded southward, ravens increasingly utilized man-made structures for nesting. In southern New Hampshire, their sizable nests are commonly found on power pylons, water towers, or the ledges of tall buildings, demonstrating their flexible approach to reproduction.
