Best Calibers for Hunting European Starling: Comparisons & Picks
Smart caliber and gauge choices for safe, practical starling control around fields, orchards, feedlots, and farm edges.
Choosing European starling hunting calibers is less about raw power and more about matching your firearm to distance, backdrop, and target behavior. Starlings are small, quick, and often encountered around barns, orchards, feed areas, pasture edges, and utility lines, so the best setup is usually the one that gives you either precise single-bird hits or forgiving patterns on short-range movers. For most hunters and landowners, that means deciding between rimfire calibers for deliberate shots and light shotgun options for birds flushing in groups or crossing close.
Where/When: In North America, European starlings are widespread across most of the continental United States and southern Canada, and they commonly use disturbed habitat such as dairies, feedlots, grazed pasture, orchards, town edges, and roost trees near food and water. Hunters often find the best patterning around livestock feed, fruiting areas, short fields, fence lines, power lines, and evening roost sites. Activity is often strongest around first light and late afternoon, and in many areas cooler months can concentrate larger flocks, though timing varies by region, crop cycles, and local regulations. Weather, livestock activity, and recent food availability can shift movement quickly, so fresh scouting matters.
European starlings are widely treated as an invasive, nonnative bird in North America, and U.S. Fish & Wildlife guidance notes they are not protected under the Migratory Bird Treaty Act. Even so, regulations still vary by state and locality, including firearm discharge rules, access restrictions, magazine limits, minimum calibers, and possible non-toxic shot requirements near wetlands or on certain properties. Whatever you choose, handle firearms safely, keep a positive backstop, and only take ethical shots you can place cleanly.

.17 HMR
The .17 HMR is the precision pick for stationary starlings in open country. It solves the problem of tiny targets sitting just far enough out that .22 LR starts to arc noticeably. Around orchard rows, pasture edges, and long fence lines, this caliber gives you a flatter trajectory and crisp accuracy with very light recoil. It matters most when birds are perched and you can set up with a safe dirt backdrop rather than shooting into buildings, equipment, or sky.
PROS
- Very flat-shooting for small-target work at moderate range
- Minimal recoil helps precise shot placement
- Excellent for deliberate shooting from a fixed position
CONS
- Less useful on birds flushing fast at close range
- Ammo usually costs more than .22 LR
- Needs a solid backstop and careful angle selection
Interesting Fact: The .17 HMR became popular because it offers rimfire convenience with a noticeably flatter path than traditional .22 LR loads.
Consider this Caliber If…
Choose .17 HMR if you hunt starlings from field edges, hay yards, or orchard lanes where shots are often 60 yards or more and you can wait for perched birds. It is especially useful for shooters who value precision over volume and want a light-kicking rifle that still reaches out.
.22 LR
If you want the most affordable and accessible answer for close, controlled shooting, .22 LR is hard to beat. This caliber solves the budget problem while still giving you enough precision for starlings on fences, feed bunks, and low perches inside sensible rimfire distance. It matters when you expect lots of practice, lots of trigger time, and repeatable shots from known positions rather than quick wing-shooting.
PROS
- Usually the least expensive option for regular practice
- Widely available in many load types
- Very light recoil makes accurate shooting easier
CONS
- Trajectory drops faster as distance stretches
- Best kept to closer shots on stationary birds
- Not ideal when birds flush in bunches
Interesting Fact: .22 LR remains one of the most common training and small-game calibers, which is a big reason so many hunters already shoot it well.
Consider this Caliber If…
Pick .22 LR if your starling hunting is mostly around close-range farm setups, baited pest-control situations where legal, or quiet practice-heavy use on private land. It is the best fit for hunters who want low recoil, low cost, and simple marksmanship on individual birds.
.22 WMR
The .22 WMR sits in the middle and solves a very common starling problem: birds that hang up beyond easy .22 LR distance, but not so far that you need centerfire speed or blast. It gives you more reach and a little more wind resistance while keeping recoil light. For mixed terrain with barns, feedlots, hedgerows, and open patches in the same property, .22 WMR is one of the most practical compromise calibers.
PROS
- More reach than .22 LR without much extra recoil
- Useful for mixed-distance pest shooting
- Good balance of precision and practical field power
CONS
- Ammo is pricier than .22 LR
- Still a single-target choice rather than a flock gun
- Can be louder than some hunters want near buildings
Interesting Fact: Common .22 WMR loads span lighter varmint bullets and heavier hollow points, which helps hunters tune the cartridge to their typical distance and conditions.
Consider this Caliber If…
Go with .22 WMR if you routinely see starlings at 50 to 100 yards and want more margin than .22 LR offers. It is a strong pick for landowners who need one rimfire caliber that can cover close work and slightly longer shots without stepping up to a centerfire rifle.
.410 bore
When your shots are close and birds rarely sit still, .410 bore starts to make a lot of sense. It solves the moving-target problem better than a rimfire by throwing a small pattern instead of relying on a single bullet. This matters around tree lines, loafing areas, and short-range passes where starlings flush fast. The tradeoff is pattern density, so choke and load selection matter more here than with larger gauges.
PROS
- Light recoil and light guns are easy to carry
- Better than rimfires for close crossing or flushing birds
- Useful where short-range snap shooting is the norm
CONS
- Thin patterns punish poor range judgment
- Ammo can be more expensive than many hunters expect
- Effective range is limited compared with 20 gauge
Interesting Fact: .410 is properly called a bore, not a gauge, because its designation refers to bore diameter rather than the traditional shotgun gauge system.
Consider this Caliber If…
Choose .410 bore if recoil sensitivity, compact guns, and close shots are your priorities. It works best for disciplined hunters who will keep shots tight, pattern their gun, and select the right choke for roost exits, tree-line ambushes, or other short-range starling opportunities.
20 gauge
For most hunters who expect moving birds and varied shot opportunities, 20 gauge is the most forgiving overall choice. It solves the pattern-density problem that makes .410 challenging, yet still keeps recoil manageable for long sessions. In practical field use, that means more margin on crossing birds near roosts, field edges, and orchard corners. If you already hunt small game or upland birds, 20 gauge may be the most versatile tool you own for starling control.
PROS
- Forgiving patterns make hits easier on moving birds
- Broad load selection and strong overall versatility
- Manageable recoil for most shooters
CONS
- More recoil and noise than rimfires or .410 bore
- Can be less handy than a small rimfire in tight work areas
- Requires attention to safe shot angles and nearby structures
Interesting Fact: Many standard 20 gauge hunting loads carry enough shot to create much denser patterns than .410 bore, which is why it is often easier to shoot well on small flying birds.
Consider this Caliber If…
Pick 20 gauge if your shots are mostly at flushed or flying starlings and you want the highest odds of clean hits without the extra bulk of a 12 gauge. It is the practical default for hunters who value flexibility, especially when one gun may also serve for dove, rabbit, squirrel, or general farm pest duty.
Final Pick Guide
If your starling shots are mostly deliberate and stationary, start with .22 LR for budget use, .22 WMR for more reach, or .17 HMR for the flattest rimfire trajectory. If birds usually flush, cross, or appear in short-range bunches, jump straight to .410 bore or, better yet for most hunters, 20 gauge. The best answer is the one that fits your terrain, normal shot distance, recoil tolerance, and how often you need to shoot moving targets instead of perched birds. Whatever you carry, check local laws before hunting, confirm whether non-toxic shot is required, and make sure your chosen load patterns or groups well at realistic distances. Safe gun handling, a reliable backstop, and ethical shot placement matter more than squeezing a few extra yards from any caliber or gauge. European starlings are widespread, invasive, and often tied to agricultural and disturbed habitats, but conditions vary property to property, so scout first and pick the tool that matches the exact problem in front of you.
