Falconry Scales
Your scale is arguably the most important piece of equipment you own. Weight management is the foundation of falconry training—and it all starts with an accurate daily weigh-in.
Accurate weight management is the cornerstone of falconry training and hunting success. A bird flown too heavy will not respond to the falconer; a bird flown too light risks health problems and can become dangerously weak. Your scale is the objective tool that removes guesswork from this critical balance. Falconers who rely on visual assessment rather than precise daily weights consistently struggle with response and motivation, and their birds are more likely to experience weight-related health emergencies.
Why Accuracy Matters
A Red-tailed Hawk’s flying weight window might be 30-50 grams. For a Kestrel, it can be as little as 5-10 grams. At these margins, your scale isn’t just a tool—it’s a safety device. An inaccurate scale can mean the difference between a responsive bird and a dangerous situation.
Types of Falconry Scales
Digital Perch Scales
The standard for modern falconry. A perch mounted on a digital platform scale. The bird steps onto the perch, you read the weight. Simple and accurate.
Pros:
- • Accuracy to 1 gram (some to 0.1g)
- • Easy to read—no interpretation needed
- • Tare function zeroes out the perch weight
- • Most can switch between grams and ounces
- • Bird can be weighed without handling
Cons:
- • Requires batteries
- • Can be affected by wind (outdoor use)
- • Cheaper models may drift over time
Best for: All falconers. This is what most people use.
Beam Balance Scales
The traditional choice. A mechanical balance with sliding weights. No batteries, no electronics—just physics.
Pros:
- • No batteries needed
- • Extremely reliable—won’t drift
- • Works in any weather
- • Some falconers prefer the ritual
Cons:
- • Harder to read quickly
- • Less precise than good digital scales
- • Bird must stay still longer for accurate reading
- • More expensive for comparable accuracy
Best for: Backup scale, or falconers who prefer analog tools.
Kitchen / Postal Scales
Many apprentices start with a high-quality kitchen or postal scale. These work well with a DIY perch attachment.
What to look for:
- • Capacity: at least 2000g (for Red-tails)
- • Resolution: 1g minimum, 0.1g preferred for Kestrels
- • Tare function (essential)
- • Stable platform for mounting a perch
- • Auto-off disabled or long timeout (bird needs time to settle)
Best for: Budget-conscious beginners. Works great with a simple T-perch bolted to a platform.
What Accuracy Do You Need?
This depends on your bird:
Building a Perch Scale
Many falconers build their own perch scales by attaching a T-perch to a digital platform scale. This is cost-effective and customizable.
Basic Design:
- • Digital platform scale (kitchen or postal scale)
- • Flat platform or base plate
- • T-perch (wrapped in cord or leather)
- • Secure mounting so the perch doesn’t shift
- • Tare the scale with the perch in place
Your sponsor has likely built several of these and can give you specific advice on dimensions and materials for your species.
Weighing Best Practices
- Same time every day. Weight fluctuates throughout the day. Morning before feeding is standard.
- Same conditions. With or without jesses, with or without anklets—pick one and be consistent.
- Record immediately. Write it down or log it in an app before you forget.
- Watch trends, not single readings. A 10g swing one day isn’t alarming. A steady downward trend is.
- Calibrate regularly. Use a known weight (a calibration weight or a sealed bag of coins) to verify accuracy.
- Protect from wind. Even slight drafts can affect readings. Weigh indoors or in the mews.
Weigh your bird at the same time every day, ideally first thing in the morning before feeding. Develop a routine so the bird steps onto the scale willingly, turning weighing into a positive experience rather than a stressful one. Record weights immediately in a log or app. Compare today's weight against the trend of the past week, not just yesterday's number. If your scale has an auto-off feature, disable it or choose a model with a long timeout, since nervous birds may need time to settle before you get an accurate reading.
Digital Weight Tracking
Recording weights in a notebook works, but digital tracking lets you spot trends faster and share data with your sponsor. Look for tools that can chart weight over time and correlate it with behavior, weather, and hunting success.
FalconryLab’s weight tracking feature is designed specifically for falconers—daily weight logging with trend visualization, feeding correlation, and shareable reports. Learn about our tracking tools.
Calibrate your digital scale monthly using a known calibration weight or a sealed reference object. Cheap kitchen scales can drift significantly over months, leading to dangerously inaccurate readings. Keep your scale clean and dry. Protect electronic components from moisture in the mews by storing the scale in a sealed container when not in use. Replace batteries at the start of each season, because low battery voltage causes reading drift before the low-battery indicator appears. Consider keeping a backup scale so you are never without this critical tool.

Weigh your bird at the same time every day, ideally first thing in the morning before feeding, to get consistent readings that reveal true weight trends. A variation of even a few grams can indicate a meaningful change in condition for smaller raptors like kestrels. Record weights immediately and review the trend over the past week rather than reacting to a single day’s reading. Digital scales with a tare function make weighing faster and more accurate.
learnEquipment.scales.commonQuestionsTitle
Beginning falconers often ask what level of scale accuracy they need. For most buteos and larger hawks, a scale accurate to 1 gram is sufficient. For smaller species like American Kestrels, where the total body weight may be under 130 grams, a scale accurate to 0.1 grams provides meaningful resolution. Perch-mount scales that allow the bird to stand naturally produce more consistent readings than platform scales where the bird may shift its weight.
learnEquipment.scales.historicalContextTitle
Weight management has been central to falconry for centuries, though the precision available to modern falconers would astonish historical practitioners. Medieval falconers gauged condition through visual cues and behavior rather than precise weight measurement. The adoption of digital gram scales in the late twentieth century transformed weight management from an art of observation into a data-driven discipline, enabling the predictive analytics and trend analysis that tools like FalconryLab now make possible.
