FeederShield: Bird Feeder Pest Deterrent Planner

Baffle Placement Diagram

This diagram updates based on your baffle height. The shaded cone shows the squirrel jump zone to keep clear.

Baffle: The cone or cylinder mounted on the pole above or below the feeder. Blocks climbing pests.
Jump zone: Squirrels can leap about 10 feet horizontally from a standstill. Keep feeders outside this radius.

Seed Preference Guide

Some seeds attract the birds you want while pests lose interest. Use this table when filling your feeder.

Seed Type	Loved By	Avoided By	Best Feeder
Safflower	Cardinals, chickadees, doves	Starlings, grackles, squirrels	Tube or hopper
Black Oil Sunflower	Most songbirds, nuthatches, titmice	Starlings (in tube feeders)	Tube with short perches
Nyjer (Thistle)	Goldfinches, pine siskins, redpolls	Squirrels, starlings	Mesh or sock feeder
White Proso Millet	Sparrows, juncos, towhees	Starlings (prefer larger seeds)	Platform or ground tray
Striped Sunflower	Cardinals, jays, woodpeckers	Squirrels (harder shell, but not avoided)	Hopper or platform
Suet (plain)	Woodpeckers, nuthatches, wrens	Starlings (use upside-down suet feeders)	Cage suet feeder

Why mixed seed causes problems

Cheap mixed seed often contains milo, wheat, and cracked corn. Most songbirds toss these filler seeds onto the ground, attracting starlings, grackles, and squirrels to the mess below. Stick to one or two targeted seed types instead.

Common Mistakes and Fixes

Even experienced birders miss these. Check your setup against this list.

Baffle too low.
A baffle at 3 feet is easy for a squirrel to jump over. Raise it to at least 5 feet, or move the feeder farther from launch points.
Feeder too close to a branch.
Squirrels will bypass any baffle if a branch hangs within 8 to 10 feet. Trim back limbs or relocate the feeder.
Using mixed seed.
Filler grains fall to the ground and attract bully birds and rodents. Switch to safflower or black oil sunflower in a tube feeder.
Baffle too small in diameter.
A narrow baffle (under 16 inches) can be defeated by raccoons reaching around it. Use an 18-inch or wider cone for pole setups.
No ground cleanup.
Shells and spilled seed on the ground invite raccoons and rats at night. Use a seed tray or clean up weekly.
Platform feeders without cages.
Open trays are the easiest target for every pest. Add a wire cage around the platform that keeps out squirrels and large birds.

Printable Setup Checklist

Print this list and check off each step as you build your pest-resistant feeding station.

Measure baffle height (at least 5 ft recommended)
Install baffle on pole before mounting feeder
Confirm feeder is 10+ ft from trees, fences, and structures
Choose single seed type (safflower or black oil sunflower)
Add seed tray or skirt to catch falling shells
Set up ground cleanup routine (weekly or after storms)
Check baffle after heavy wind or ice
Observe for 3 days and adjust if pests still reach feeder

Why FeederShield Exists

Birdseed waste from squirrels, raccoons, and bully birds costs backyard birders real money every season. A single squirrel can empty a full feeder in one morning. Most advice online is vague: "use a baffle" or "move the feeder" without saying how high, how far, or what seed to switch to.

This planner turns general advice into specific actions. You tell it what you have, and it tells you exactly what to change. The baffle diagram, seed table, and mistake list are based on wildlife behavior research and feedback from birding communities.
