Illinois: Attracting and Feeding Hummingbirds – A Complete Guide
Illinois is solid Ruby‑throated Hummingbird territory.
Each spring, these tiny migrants return from Central America to nest across the state, visiting gardens, woodland edges, and prairie plantings from May through early fall.
Key takeaways
-
Ruby‑throated Hummingbird is the only regular breeding hummingbird in Illinois; Rufous appears rarely during migration.
-
Put feeders out by mid‑April and keep them up into early October.
-
Use the 4‑to‑1 sugar‑water recipe with no red dye and clean feeders frequently in summer.
-
Native plants like red columbine, bee balm, cardinal flower, and trumpet honeysuckle are excellent for Illinois hummingbirds.
What hummingbirds live in Illinois?
-
Ruby‑throated Hummingbird – A common migrant and summer resident statewide, and the only species known to nest east of the Mississippi River, including all of Illinois.
-
Rufous Hummingbird – Occasionally recorded in Illinois, mainly during migration and sometimes late fall; considered an uncommon or rare visitor.
Most backyard birders in Illinois will only see Ruby‑throats, but Rufous is a possible surprise!
When do hummingbirds visit Illinois?
Timing is well documented by Illinois DNR, Extension, and local bird groups.
Seasonal pattern:
-
Spring arrival – Spring migrants begin reaching Illinois in mid‑April, with Ruby‑throats usually arriving in central Illinois around May 1.
-
Nesting season – Nesting takes place from May through July, and Ruby‑throats are common summer residents statewide.
-
Fall migration and departure – Fall migrants begin moving through by August; males typically leave first, followed by females. Many birds are gone by late September–early October.
Feeder timing that fits both state and general recommendations:
-
Put feeders out by mid‑April so they’re ready when migrants arrive.
-
Keep feeders up until at least early October; many Illinois bird stores advise leaving them up until around Halloween, then taking them down if no hummingbirds are visiting.
Best nectar recipe for Illinois hummingbirds
Use the same recipe you recommend everywhere.
Standard mix:
-
1 part white granulated sugar
-
4 parts clean water
Instructions:
-
Bring water to a brief boil.
-
Stir in sugar until fully dissolved.
-
Let it cool, then fill feeders.
-
Store extra nectar in the refrigerator and use within a week.
Key guidelines:
-
Do use only plain white table sugar (sucrose).
-
Do not use honey, brown sugar, raw sugar, or artificial sweeteners.
-
Do not add red dye; the feeder’s red parts are enough to attract birds.
How often to clean feeders in Illinois
Illinois summers can be hot and humid, especially in the southern and central parts of the state.
Cleaning schedule:
-
In cooler spring and fall weather, change nectar and clean feeders every 3–4 days.
-
In hot, humid summer weather, change nectar every 1–2 days, especially if feeders are in full sun.
Cleaning basics:
-
Empty any leftover nectar.
-
Rinse with warm or hot water.
-
Scrub reservoir and base with a bottle brush; use a small brush for ports and seams.
-
For stubborn mold, soak in a mild vinegar‑and‑water solution (about 1:4), rinse thoroughly, and let dry before refilling.
Where to hang hummingbird feeders in Illinois
Good placement makes feeders safer and more attractive.
Suggestions that work well across Illinois:
-
Choose partial shade or morning sun/afternoon shade to slow nectar spoilage.
-
Hang feeders near flower beds, shrubs, or native plantings, so hummingbirds can move easily between natural nectar and feeders.
-
Place feeders about 4–6 feet above the ground, away from dense cover where cats might hide.
-
Keep feeders some distance from large windows or use decals to reduce collision risk.
If one male hogs the feeder:
-
Use two or more small feeders spaced apart or around corners to reduce aggression.
Native plants that attract hummingbirds in Illinois
Illinois has an excellent suite of Eastern natives that line up with Ruby‑throat migration and nesting.
Illinois Extension and other native‑plant guides recommend:
Wildflowers and perennials
- Red columbine (Aquilegia canadensis) – early spring blooms that match Ruby‑throat arrival.
-
Bee balm / wild bergamot (Monarda didyma, M. fistulosa) – mid‑summer blooms with abundant nectar.
-
Cardinal flower (Lobelia cardinalis) – brilliant red spikes in late summer, ideal for fueling southbound migrants.
- Great blue lobelia (Lobelia siphilitica) – blue tubular flowers also used by hummingbirds.
-
Foxglove beardtongue (Penstemon digitalis) – white tubular flowers that hummingbirds visit, good in a range of soils.
- Blazing stars (Liatris scariosa, L. pycnostachya) – tall purple spikes that attract hummingbirds and pollinators, especially in prairie‑style plantings.
Vines and shrubs
- Trumpet honeysuckle (Lonicera sempervirens) – native vine with tubular red flowers; highlighted by Illinois Extension.
-
Native shrubs like elderberry (Sambucus canadensis) and winterberry holly (Ilex verticillata) provide structure, insect life, and berries that support overall bird habitat.
Creating a hummingbird‑friendly yard in Illinois
Illinois yards can act as important stopovers in the Ruby‑throat’s long journey.
Helpful habitat ideas:
-
Layer plants – Combine low perennials (columbine, bee balm, cardinal flower), mid‑height shrubs (elderberry, winterberry), and small trees for perches and nesting cover.
In an Illinois yard, you can create a layered hummingbird garden along a 10‑ to 15‑foot fence or patio edge. In the back layer, plant 2–3 native shrubs or small trees such as elderberry and winterberry holly, spaced 6–8 feet apart to provide cover, perches, and flowers/berries that support insects and other birds. In front of them, add a middle row of coral honeysuckle on a trellis and one or two additional shrubs, like a compact serviceberry, to build a flowering wall. Along the front edge in full or partial sun, mass clumps of red columbine, bee balm, blazing star, and cardinal flower every 18–24 inches so something is blooming from spring through late summer. This three‑layer layout fits a typical Illinois backyard and gives Ruby‑throated Hummingbirds safe cover, high lookout branches, and a continuous nectar buffet at eye level.
-
Provide water – A shallow birdbath, dripper, or mister gives hummingbirds a place to drink and bathe, especially in summer heat.
- Limit pesticides – Ruby‑throats eat small insects and spiders for protein; reducing chemicals protects this food source.
-
Leave perches – Keep a few small dead branches or open twigs where hummingbirds can rest and survey their territory.
Common hummingbird questions in Illinois
When should I put out hummingbird feeders in Illinois?
Illinois DNR notes Ruby‑throats start arriving in mid‑April; local birding sources recommend having feeders up by mid‑April, with birds typically reaching central Illinois around May 1.
When should I take down hummingbird feeders in Illinois?
Most Ruby‑throats leave by late September, but some bird stores suggest keeping feeders up until Halloween and then removing them if no hummingbirds are visiting.
Do feeders keep hummingbirds from migrating?
No. Illinois Extension notes hummingbirds store up extra energy before migration, but migration itself is driven by day length and internal cues, not by feeders.
What are the best native plants if I can only plant a few?
If space is limited, you can recommend red columbine, bee balm, cardinal flower, and trumpet honeysuckle—these are repeatedly listed by IDNR and Illinois Extension as top hummingbird plants.
