Reading the Arrow
Assumes the Hunting Primer. New here? Start there first.
Your objective
By the end, you'll be able to identify what blood coverage, hair, tallow, and smell on a recovered arrow tell you about where the deer was hit — and use that read to decide your next move.
The arrow flew, the deer lurched and bounded off, and now silence. Every instinct says go find the deer. But the most important clue you have is lying in the leaves ten yards from where you’re standing. Find the arrow first. A thirty-second read of it tells you more than an hour of guessing will.
Quick recall
Quick recall from Arrow Placement & Deer Anatomy — which two organs sit behind the near front leg on a broadside deer?
Why the arrow is your first clue
Archery kills by hemorrhage — the broadhead slices tissue and the deer bleeds out. That means what coats the arrow is a direct sample of every structure it passed through. Before the blood trail tells you a story, the arrow tells it first.
Step one every time: stay in your stand, watch the deer out of sight, mark where it stood, then walk directly to the arrow. Don’t start down the trail. Don’t speculate. Read the shaft.
The why Why a pass-through arrow gives you even more information
When an arrow punches all the way through — entry hole and exit hole — you have two data points: the blood from the entry and the blood from the exit. A pass-through also means the broadhead is likely buried in the leaves behind the deer’s standing position, typically two to three feet past where it stood. Find both the shaft and the broadhead for the full picture. A pass-through generally indicates good penetration and is a positive sign.
Blood: color and bubbles are the headline
Blood on the arrow is the most diagnostic clue you have. Read it under good light (use your phone flashlight in dim conditions):
- Bright pink or red with visible air bubbles / frothy — a lung hit. The bubbles are literally air from the lung tissue. This is the best possible read. The deer is unlikely to go far.
- Bright, heavy, solid red, no bubbles — a heart or major artery hit. Excellent — expect a short, blood-heavy trail.
- Dark, deep-red blood, possibly with tiny flecks of tissue — a liver hit. Lethal, but the liver is slower to bleed out. You need to wait.
- Brown, greenish, or a reddish fluid that smells of decay or digested food — a gut (paunch) hit. Foul odor is the giveaway. The worst read, but still recoverable with patience.
Tallow, hair, and other shaft clues
Blood is not the only thing on the arrow. Two other materials carry major information:
Tallow is the white, waxy animal fat that coats the brisket (lower chest) and the back (along the spine). If the arrow has a white, greasy coating with little blood, it likely passed through fat without piercing vitals. That is a marginal hit — treat it as a gut-or-worse scenario and give it maximum time.
Hair on the shaft is a secondary indicator:
| Hair description | Likely location |
|---|---|
| Coarse, dark, with black tips | Upper chest — heart/lung zone |
| Short, stiff, white or cream | Lower belly — gut/brisket |
| Very dark, long, and coarse | High back near spine |
| Fine, reddish-brown | Side of body — could be anything |
Hair alone isn’t conclusive, but it confirms or contradicts what the blood is saying.
The visual anchor — read the shaft zone by zone
Read these arrows — mixed cases
These come in mixed order on purpose. Identification sharpens when the categories are jumbled, just like the field gives you.
Knowledge check
You pick up the arrow and the first third of the shaft is coated in bright pink blood full of small air bubbles. What does this tell you?
Knowledge check
The arrow shaft has a white, waxy, greasy coating with very little blood — almost no red color at all. What is the most likely read?
Knowledge check
The arrow has dark, reddish-brown blood and when you bring it close, there is a distinct, sour, foul odor. What's the read and what do you do next?
Take it to the woods
Build the arrow-reading habit before you ever make a shot at game. The thirty seconds it takes will directly affect whether you recover the deer.
After the shot: read the arrow first

If you remember nothing else
- Find and read the arrow before you take a single tracking step — it is your first and most reliable clue.
- Bright pink or red blood with air bubbles means a lung hit — the best outcome. Solid bright red with no bubbles is heart or artery.
- Dark red blood, foul smell, or brown-green fluid with food matter means liver or gut — slow down and wait.
- White waxy tallow on the shaft means the arrow passed through fat, not vitals — a likely marginal hit.
- Hair color and coarseness give a second read: coarse dark chest hair for vitals, short white belly hair for a low gut wound.
- A clean, pass-through arrow doubles your entry-and-exit information — look for it behind the deer's position.
How ready do you feel?
