The hummingbirds of Arizona
Anna's Hummingbird
Calypte anna
Present all year in Arizona.
How to recognize it: Stocky and gray-green; male's whole crown and throat glow rose-pink; females show a small pink throat spot.
The hummingbird most likely to stay through a Pacific Northwest winter. It drops into torpor on frosty nights and depends on feeders that do not freeze.
Rufous Hummingbird
Selasphorus rufus
Passes through in migration in Arizona.
How to recognize it: Male is bright orange-copper with a scarlet throat; females green above with rusty flanks and tail base.
Breeds farther north than any other hummingbird, into southeast Alaska, and is famous for chasing every other hummingbird off a feeder. A few winter along the Gulf Coast each year.
Black-chinned Hummingbird
Archilochus alexandri
Summer nester in Arizona.
How to recognize it: Plain green above and dull gray below; male's black throat has a thin violet band only visible in good light. Pumps its tail while hovering.
The western counterpart of the Ruby-throated, common in canyons, river woods and suburbs from Texas to the inland Northwest.
Broad-tailed Hummingbird
Selasphorus platycercus
Summer nester in Arizona.
How to recognize it: Green back and rose-magenta throat on males; the male's wings make a loud metallic trill you hear before you see him.
The summer hummingbird of the Rocky Mountains, nesting up to about 10,500 feet. Arrives while nights still drop below freezing.
Costa's Hummingbird
Calypte costae
Present all year in Arizona.
How to recognize it: Tiny and compact; male's purple crown and throat flare out into long side 'mustaches'.
A desert hummingbird that nests in late winter and spring, when desert shrubs bloom, then leaves the hottest lowlands in summer.
Calliope Hummingbird
Selasphorus calliope
Passes through in migration in Arizona.
How to recognize it: The smallest bird in the US and Canada, about 3 inches; male's throat is streaked with wine-red rays on white.
Nests in mountain forests of the interior West and passes through lower states in late summer.
Broad-billed Hummingbird
Cynanthus latirostris
Summer nester in Arizona.
How to recognize it: Dark green with a blue throat on males and a bright red-orange bill tipped in black.
A Mexican species whose range just reaches the canyons of southeast Arizona and southwest New Mexico.
Rivoli's Hummingbird
Eugenes fulgens
Summer nester in Arizona.
How to recognize it: Large and dark; male with a purple crown and green throat. Long straight bill.
Formerly called Magnificent Hummingbird. Found in high sky-island canyons of Arizona and New Mexico, and in west Texas.
When to put out hummingbird feeders in Arizona
Scouts reach Arizona around March 1, a little earlier in the south of the state and later at elevation. Males travel ahead of females by a week or more and arrive before many native flowers open, so a feeder hung two weeks early, by February 15, gets used. Across 67 Arizona cities in the NOAA 1991–2020 normals, the typical last spring freeze falls around January 7, so most birds arrive after the frosts are over.
Keeping feeders up all year in Arizona
Anna's Hummingbird, Costa's Hummingbird live in Arizona year-round. In cold snaps a feeder can be the only food source, so keep one feeder up, swap in fresh nectar before it freezes and hang it near a sheltered wall. Migrants still pass through from about March 1 to October 15.
Native flowers for hummingbirds in Arizona
Feeders bring hummingbirds in; flowers and the insects on them keep them nesting nearby. These natives grow in Arizona (USDA 4b–10b):
- Cardinal flower (Lobelia cardinalis): Scarlet late-summer spikes; a hummingbird magnet in moist soil.
- Wild bergamot (Monarda fistulosa): Tubular flowers for hummingbirds and seed heads for finches.
- Golden currant (Ribes aureum): Early yellow flowers for hummingbirds, then summer fruit.
- Rocky Mountain bee plant (Cleome serrulata): Nectar-rich in summer, seed for finches in fall.
- Scarlet gilia (Ipomopsis aggregata): Red trumpets for Broad-tailed and Rufous hummingbirds.
- Rocky Mountain penstemon (Penstemon strictus): Blue-violet spikes favored by Broad-tailed Hummingbirds.
- Desert willow (Chilopsis linearis): Orchid-like flowers through summer for hummingbirds and orioles.
- Ocotillo (Fouquieria splendens): Red spring flower spikes timed to hummingbird and oriole migration.
Nectar and cleaning
- Mix 1 cup plain white sugar into 4 cups water; boiling is optional if you use clean water and change it on schedule.
- No red dye, honey, brown sugar or sweeteners. A red feeder is enough to attract them.
- Change nectar every 2 days above 80°F, every 4–5 days in cooler weather; cloudy nectar has fermented.
- Scrub ports with a bottle brush at each change; soak monthly in 1 part vinegar to 4 parts water.
- Use an ant moat and keep feeders out of full afternoon sun to slow spoilage.
Frequently asked
What hummingbirds live in Arizona?
8 hummingbirds occur regularly in Arizona: Anna's Hummingbird (present all year); Rufous Hummingbird (passes through in migration); Black-chinned Hummingbird (summer nester); Broad-tailed Hummingbird (summer nester); Costa's Hummingbird (present all year); Calliope Hummingbird (passes through in migration); Broad-billed Hummingbird (summer nester); Rivoli's Hummingbird (summer nester).
When should I put out hummingbird feeders in Arizona?
Hang feeders by about February 15. The first hummingbirds usually reach Arizona around March 1, and early birds find little in bloom.
When should I take hummingbird feeders down in Arizona?
You don't have to. Anna's Hummingbird, Costa's Hummingbird stay in Arizona all year, so many people keep one feeder going through winter and keep it from freezing.
Can hummingbirds handle a late frost in Arizona?
The typical last spring freeze across Arizona cities is around January 7. Hummingbirds survive cold nights by dropping into torpor, but nectar feeders matter most when flowers are frosted. Bring a feeder in overnight if it freezes solid and rehang it at dawn.
What is the right sugar water ratio?
One part plain white sugar to four parts water, no red dye, no honey. Change it every two days when highs are above 80°F and every four to five days in cooler weather.

Hummingbird feeders and ant moats
Feeders and add-ons that suit the nectar schedule above.
Hanging Basin Feeder and Water Bowl
A single open basin that hangs from a hook and does two jobs: a seed tray through the growing season, a shallow water bowl the rest of the year. Seed or water goes straight in — no reservoir, no perches, nothing to assemble beyond the hanging chains.Three chains run from the rim to one S-hook, so the basin hangs level under a bracket, a shepherd's hook or a low branch. Put it where you can watch it from a window, and where a cat can't launch from a fence.The rim is low and the floor is open, so birds can land anywhere around the edge instead of fighting over a perch. It also means the bowl needs wiping out every few days: hulls and droppings land in the water, and a rinse with hot water and a brush keeps it clean.The basin has a wood-grain finish and hangs from black metal chains.
Round Suet Ball Cage
A small round wire cage made to hold one suet or fat ball. The hinged cage opens for refilling and closes with a simple wire latch. A short chain and hook are included for hanging. Available in gold-colored or black finish. This is a suet holder, not a hummingbird feeder.
Five-Port Hummingbird Feeder
A compact red hummingbird feeder with a clear 8-ounce reservoir, five flower-shaped feeding ports, and five curved perches. The set includes a separate ant-moat cup and an S-hook for hanging. The wide base separates for routine washing. Use plain white sugar nectar at a 1:4 sugar-to-water ratio; never add dye.
Hummingbird Ant Moat Hooks, 4-Pack
Four red metal S-hooks, each with a built-in water cup. Hang the hook from your bracket, hang the feeder below it, and fill the cup with water. Ants walking down toward the nectar hit the water and stop.Specs Material: metal with red coating Pack: 4 moat hooks + 4 small cleaning brushes Fits most hanging feeders with a wire or loop hanger Use Plain water only. Never add oil or insecticide to the cup. Top up every few days in hot weather; a dry moat does nothing.
