How to Create a Bear‐Proof Bird Feeding Station

Last Updated: June 17, 2022

Do black bears live in your area? It can be frustrating (and scary!) to see these critters hanging around your bird feeding stations after they wake up from hibernation. Try not to worry, though—with the right tools and supplies, you can bear-proof your bird feeding station. We've covered everything you need to know, so you can feed the birds without any bears interfering.

1

Pick two trees.

They should be about 10 to 50 feet (3 to 20 m) apart. They need to be at least 4" in diameter at the height for attacking the wire. The desired height for attaching the wire should be at least 8' -- higher for wider tree spacing to allow for droop.

2

Mount the angle brackets to the back of the winch.

Keep the angle away from the handle and parallel to the drum. You may need to drill holes in the bracket to fit the winch hole pattern.

3

Mount the winch to one tree with the direction control on the bottom.

Use lag bolts to mount the winch.

4

Put the eye bolt into the same tree as the winch.

Use a ladder to accomplish this task.

5

Mount the other eye bolt in the other tree.

Mount it at approximately the same height as the first eye bolts. (The picture shows wire with thimble and clamp, and eye bolt. A Quick Link was not used, but is recommended.)

6

Install the thimble in the free end of the wire.

Use one or two cable clamps to install the thimble.

7

Connect the thimble eye to this last tree's eye bolt.

Use a Quick Link to make this connection.

8

Unwind the wire completely.

Thread the loose end through the pulley or disassemble the pulley to insert the wire. Keep in mind that if you do not have a pulley that disassembles, this is a crucial step!

9

Move the ladder back to the tree with the winch.

Using the other Quick Link, attach the pulley to the eye bolt above the winch.

10

Attach the free end of the wire to the winch drum using one cable clamp.

There is no strain on this attachment, so one clamp is very adequate.

11

Wind the loose wire onto the drum.

Maintain some tension on the loose wire as you wind it. Add one or more S-hooks to roughly the middle of the wire before getting the wire taut. Place a feeder or other weight on the hook for ease in lowering the wire. Two people are helpful, but not critical, at this step.

12

Refill the feeders.

Toggle the winch direction control and hold the handle to unwind under control.

Warnings

Be very careful working on ladders, and have a second person hold the ladder as needed.

Things You'll Need

Small hand winch - The smallest seem to be about 600# capacity; this is more than adequate. Get one with an empty reel or remove the web strap.
Spool of approximately 1/8" wire - Make sure it's one suitable for outdoor use. The length needed will be at least the distance between trees plus three times the height from the winch to the upper pulley. Since this wire often comes in 100' spools, that can handle most needs.
Turning block or pulley - A small block is used to transfer the pull off the wire from vertical, to the winch, to horizontal between trees. One with a removable wheel is ideal for ease of assembly and possible maintenance. A "single sheave fixed eye pulley" is the precise name.
Two "Quick Links" - These attach the picture to an eye bolts at one end and the free end of the cable to the other eyebolt
Wire rope thimble - Some come with clamps. Get one for your size wire. This is used to make a loop at the wire's free end that will not fail because of stress or wear. The clamp (one is sufficient) is used to hold the thimble in the loop. Extra clamps can be attached or used for holding feeder hooks.
2 shelf angle brackets - These attach the winch to a tree. These should be about 5" to 6" long, an inch wide, and 1/8” thick to be able to bolt the winch to one arm and the tree with the other arm. Get zinc plated or stainless for outdoor use.
3 to 5 cable clamps for 1/8” cable - One or two are used to attach the thing. The others are used to attach hooks to hold the feeders.
2 or 3 "S" hooks - These attach feeders to the wire. Small ones made from approximately 1/8” material are strong enough and big enough. Bigger hooks need bigger cable clamps!
2 eye bolts with a wood or lag screw - Size is not critical, but something on the order of 1/4” screw and 1" eye. Get zinc or chrome plated, brass, or stainless steel for outdoor use.
Lag bolts, machine screw bolts, washers, and nuts - These are used to mount angle brackets to winch and lag to tree. Zinc or chrome plated, brass, or stainless steel.
