A hawk on a fence post is mostly stillness — and that is what makes it hard. There is no dramatic color to hide behind, just earth tones, a powerful silhouette, and an eye that has to feel alive. Get those three things right and a raptor study reads as a portrait. Miss the eye and it reads as a stuffed specimen.
Start with the silhouette
Before any feathers, get the overall shape and posture. Raptors have heavy, compact bodies, a distinct head-to-shoulder line, and feet that grip with obvious weight. Block the whole bird as a single flat shape and check it against your reference squinted down to a silhouette. If the silhouette reads as "hawk" — broad shoulders, hooked head, sturdy stance — the rest is detail. If it doesn't, no amount of feather rendering will rescue it.
Pay special attention to the head angle. A raptor's intensity comes from the forward set of the eyes and the slight downward tilt of the hooked bill. A few degrees of head rotation changes the entire mood.
Plumage: warm earths, layered
Most hawks and eagles live in a narrow band of browns: warm sienna, cool umber, cream, and charcoal. Mix these from your limited palette rather than reaching for tube browns — Burnt Sienna with Ultramarine gives you the full range from warm rust to cold gray-brown by shifting the ratio.
Work light to dark in broad passes:
- First wash: the lightest local color across the whole bird, leaving paper for the palest breast streaking.
- Second pass: the mid-tone that establishes the back, wing coverts, and head, wet-on-dry so edges stay crisp where feather groups meet.
- Third pass: the darks — flight feathers, the mask around the eye, the deep shadow under the wing.
Barring and streaking without going insane
The barred chest of a Red-shouldered Hawk or the fine streaking of a juvenile can swallow hours if you paint every mark. Don't. Barring follows the curve of the body — it is a series of arcs wrapping a cylinder, denser and more compressed at the edges where the chest turns away. Render it fully in the area of sharpest focus (usually the upper breast) and let it dissolve into suggestion toward the flanks. The viewer's eye fills in the rest.
The eye is the whole painting
A raptor's eye is large, round, and forward-facing, with a heavy brow that casts it into shadow. The iris is often a striking yellow, orange, or deep red-brown. The single most important move is the catchlight: one small spot of untouched paper, placed consistently with your light source. Paint the iris color around it, drop a near-black pupil, and deepen the shadow of the brow above. Keep the catchlight clean and small. If you lose it, lift it back out with a damp brush while the area is dry.
The cere (the fleshy base of the bill) and the bare legs are often the same warm yellow as the eye — echoing that color ties the portrait together.
Owls are a special case
Owls trade the hard hawk silhouette for soft, sound-dampening plumage, which means more soft edges and subtler value transitions. Their facial disc funnels your attention straight to the eyes, so the disc's concentric pattern is worth rendering carefully. Work wetter and let edges bloom — the opposite discipline from a hawk's crisp flight feathers.
A focused practice session
Try a ten-minute study of just the head: silhouette, the brow-shadowed eye with its single catchlight, and the hooked bill. Skip the body entirely. Do it three days running with a different species each day. The eye gets faster and more confident every time, and that is the part that makes or breaks every raptor you'll ever paint.
