This simple building plan shows how to make a nesting shelf for robins (Turdus migratorius) where they can build a nest and raise their young. The open design is also attractive to phoebes and house finches.
There are also Free Nesting Box Plans here for chickadees, wrens, and bluebirds.
Nesting Shelf For Robins
If you are new to nesting boxes or shelves, the most important thing to know is that each bird species needs a different style. There is no one-style-suits-all. Every species has unique nesting habits in the wild and the best nesting boxes and shelves mimic these conditions. We know the design is successful when the bird is attracted to the box, uses it to safely rear its young, and predators are minimized.
Birdhouses Versus Nesting Boxes: What’s Best For Birds explains the key differences.
While the ideal is to provide diverse habitat with lots of suitable trees, shrubs, and food sources and never require any human-made nesting boxes, the reality is that robins have been urbanized with us and that can make nesting complicated.
The robin may establish its first nest of the season in late spring on a porch shelf while it’s still quiet outside. But, by the time the eggs are hatching, the humans start their spring gardening and suddenly that quiet location is interrupted many times a day.
Robins, like many nesting birds, are highly territorial and having humans constantly around the nest site is upsetting.
Each baby in the nest needs feeding up to 40 times a day. For a clutch of four that means the parents are back and forth perhaps 120 times a day bringing food like grubs and worms.
Add in the constant threat of predators like blue jays, crows, ravens, snakes, and squirrels, and it’s not easy being a robin.
After several seasons of robins choosing troublesome nesting spots around our house, I decided to install a nesting shelf up on the house wall under an overhang.
Now they have a safer place to nest, close to their food sources, and I don’t have to feel guilty every time I head out to the garden.

- Robin Nesting Shelf Building Instructions
This project is designed for American robins (Turdus migratorius), or what we commonly call “robins” in Canada and the United States. This is a different species than European robins (Erithacus rubecula)—also known as “robins”, which are smaller birds in the flycatcher family. You can see the difference here.
Unlike many other birds that use typical nesting boxes with round entry holes, robins prefer an open shelf, much like a tree branch supports a nest. Tucked up under house eaves or a porch roof, they have a secure location protected from rain, but accessible to their food sources.
If you can, place your robin nesting shelf between 6 and 15 feet above the ground. The building plan (below) includes a roof but you could leave it off if your location has sufficient overhang.
This design is adapted from other robin shelf plans that have been used for decades.
Robin Nesting Shelf Building Instructions
- Electric miter saw
- (14) #8 2-inch deck screws (to assemble shelf)
- (2) #8 3-inch deck screws (to attach shelf to wall)
- Drill bits: 7/64″and ¼” (one-quarter inch)
- Wood glue
1-inch-thick pine, cypress, cedar, or non-toxic exterior grade pressure-treated plywood.
If you use thinner wood, use smaller screws or a nail gun to assemble your shelf.
You can read more about recommended wood for nesting boxes here.
- Back: 9.25 x 13”
- Floor: 6.75 x 9.25″
- Lip: 2 x 9.25”
- Roof: 8.5 x 9.25″ | One long end will be cut at 18.5° angle*.
- (2) Side supports: 3x 8.5”| Top edges will be cut at 18.5°angle*.
*You can choose any angle around this amount (e.g. 20°). Just be sure to choose the same angle for roof and side supports.
- Cut wood pieces as listed above.
- Add 18.5-degree (or similar) angled cuts to both the roof and sides as shown in the pictures below. The sloped roof will prevent rain from collecting on it.
- Drill eight one-quarter-inch holes in floor piece for water drainage.
- Gently sand all wood edges until smooth.
- Predrill all screw holes using a 7/64″drill bit. Use two screws for each attachment.
- To assemble, start with floor piece. Align back end of floor (9.25″ wide by 6.75″ deep) with bottom of back piece (9.25″ wide by 13″ tall). Apply wood glue to joins before screwing in place.
- Attach the two side supports inset one-inch from side edges of floor. Secure them in place through back or floor.
- Glue and attach roof, securing it to back and sides.
- Glue and attach lip to front of floor. Allow an inch of lip above the floor. This helps prevent the nest from falling off the shelf.
That’s it. Hang your shelf between 6 and 15-feet above ground on an exterior wall, preferably below an overhang. Watch and see who moves in at nesting time. It might be robins, phoebes, or house finches.
American Robin (Turdus migratorius)
Member of thrush bird family

- Nesting location: tree branches or ledges
- Eggs: 3 to 5, sky-blue or blue-green in color. Lay one per day.
- Broods per season: 2 to 3
- Incubation: 12 to 14 days. Female incubates, male and female provide food.
- Days to Fledge: 13 to 15 days
- Diet: Autumn and winter: fruits including tomatoes and berries. Spring and summer: soft invertebrates including earthworms, caterpillars, beetles.
- Range: Widespread throughout United States and Canada
European Robin & American Robin
While both of these birds are called “robins” in their native territories, they are different species and not closely related. The one common trait is their red breasts.
European robins (Erithacus rubecula) belong to the old-world flycatcher family. At 5-inches long, they are considerably smaller than American robins.
American robins (Turdus migratorius) belong to the thrush family. At 11-inches long, they are two times the size of European robins.

Bird Health & Safety
The best thing we can do to support wildlife including birds is to grow the plant species they need for food (mostly bugs and seeds) and habitat along with fresh water, avoid the use of any pollutants, pesticides, and herbicides, and let the garden get “messy” to provide the dead and decaying matter that supports life.
While bird feeders are enjoyable for us, they are not necessary for bird survival. If you do have them, keep them clean and disinfected and remove them if there are reports or signs of any communicable diseases.
