Alabama field notes, April.
Alabama hosts 14 commonly-seen blue and blue-toned bird species across its mixed pine, hardwood, and wetland habitats. The most beloved is the Eastern Bluebird, which has rebounded across the state thanks to backyard nest-box campaigns. The other 13 are a mix of resident songbirds, summer breeders, and winter visitors. Knowing which is which is mostly about silhouette, habitat, and time of year.
The headline species: Eastern Bluebird
The Eastern Bluebird (Sialia sialis) is what most Alabamians mean by “the bluebird”. Resident year-round across the state, fond of open fields with scattered perches, partial to nest boxes. Bright blue back, rusty breast, white belly. The male in spring is one of the most photogenic birds in the southeast.
If you want bluebirds in your yard, the single biggest thing you can do is put up a proper nest box with the right entrance hole.
The 14 blue and blue-toned birds of Alabama
Brilliant blue resident songbirds:
- Eastern Bluebird - the bluebird. Open fields, fences, nest boxes. Year-round.
- Blue Jay - loud, larger, blue with a crest. Year-round, woodlands and suburbs.
- Blue Grosbeak - deep cobalt blue with rusty wing bars. Summer breeder, brushy edges.
- Indigo Bunting - all over electric blue. Summer breeder, road edges and field margins.
Blue-tinted herons and waders:
- Great Blue Heron - the big grey-blue wader, year-round in any wet habitat.
- Little Blue Heron - small dark-blue adult, pure white juvenile. Marshes.
- Tricolored Heron - slate blue with white belly stripe. Coastal Alabama.
Blue-grey songbirds:
- Blue-gray Gnatcatcher - tiny, restless, blue-grey with a white eye-ring. Summer.
- Cerulean Warbler - sky-blue tiny warbler. Migration, hardwood forest.
- Black-throated Blue Warbler - blue male, olive female. Migration only in Alabama.
Less obvious but blue-categorised:
- Belted Kingfisher - blue-grey crest and breast band, year-round near water.
- Purple Martin - dark blue-purple in good light. Summer breeder.
- Tree Swallow - iridescent blue-green back. Winter and migration on coastal Alabama.
- Eastern Kingbird - dark blue-grey back, white belly. Summer breeder.
How to tell them apart at a glance
The four blue songbirds people most often confuse:
- Eastern Bluebird has a rusty breast. Blue back + rust front = bluebird.
- Blue Jay has a crest and bold white wing bars. Larger than the others.
- Indigo Bunting is all blue, no rust, smaller than a bluebird. Singing from a fence wire in June is almost certainly this.
- Blue Grosbeak is bigger than Indigo Bunting and has rusty wing bars on a blue body.
If it’s tiny and bouncing through hardwoods, it’s a Blue-gray Gnatcatcher.
Where to find them in Alabama
- Bankhead National Forest - hardwood specialists (Cerulean Warbler, Indigo Bunting).
- Wheeler National Wildlife Refuge - waders (Great Blue Heron, Little Blue Heron) plus winter sparrows.
- Mobile-Tensaw Delta - the full wetland blue list including Belted Kingfisher and Tricolored Heron.
- Talladega National Forest - mixed pine/hardwood, good for Eastern Bluebird in open patches.
- Coastal Alabama (Dauphin Island, Fort Morgan) - migration concentration for warblers in April-May.
How to attract Eastern Bluebirds to your yard
The recipe is well-established:
- A proper nest box - cedar, 1.5-inch entrance hole, sized exactly for bluebirds (sparrows and starlings can’t enter).
- Mount on a pole, not a tree. 5-6 feet up.
- Open ground in front - they hunt from a perch, dive to insects on short grass.
- Provide mealworms in early spring while insects are still scarce.

The bottom line
Alabama’s blue list runs from the household Eastern Bluebird to coastal Tricolored Herons, with electric Indigo Buntings on every roadside fence in summer. The state is one of the best in the southeast for backyard bluebird recovery. Put up a properly-sized box and you’ll have a pair within a season.
