Inside: A complete guide to blue birds in Kentucky including a full-color photo of each blue bird, details about habitat, diet – including feeder food they’ll eat, appearance, nesting habits, and a range map to show you where in the state you can expect to see them.
You spotted a blue-colored bird in Kentucky. The next step is to identify it. I got you!
With more than 20 years of experience attracting backyard birds to my yard (Wisconsin), I’ve studied all of the blue-colored birds in my area so I have the information you’re looking for. For the remaining blue-colored bird species, I rely on my trusty sourcebooks and friends at The Cornell Lab of Ornithology to guide me.
I’ll never forget my first blue-colored bird spotting – which I later learned was an Indigo Bunting! You’d have thought I’d seen Elvis in my backyard. I screamed “blue bird, blue bird” and ran around my house like a lunatic looking for my camera. It was still there when I returned, but not for long. I looked him up in my guide book and there he was in all his royal blue glory. Breathtaking.
All Variations Of Blue Birds In Kentucky Are Included
This article includes blue-colored wild bird species in Kentucky that range in size from tiny & small to large. The bird could be all blue or partly blue with a secondary color. They could be bright blue birds, dark blue birds, or light blue birds – all variations are here!
Some blue-colored birds live in Kentucky year-round, others are here to breed, and others are migrating through. The range maps are color-coded so you know if it’s a year-round bird, there to breed, migrating through, or there during a nonbreeding time.
I also included a beautiful photo to help you identify these blue beauties along with detail such as:
- Size + appearance description
- Diet in the wild and at the feeder
- Nest & eggs description
- Range map
My hope is that this article will help you easily identify the blue bird you saw or plan to see one day. So let’s get at it, here are the blue-colored birds in Kentucky:
Blue-Colored Birds In Kentucky
Appearance: 7″ long, steel blue glossy on top, chestnut forehead and throat, and rust-orange underparts. Long forked tail with a white base. The female’s coloring is lighter and the tail shorter.
Diet: Insects, preferably beetles, wasps, and flies. Drinks by skimming the surface of the water.
Feeder food: Not likely to visit a feeder.
Habitat: Open fields and pastures.
Nesting: A barn swallow typically nests in or on a manmade structure such as a barn. Builds nests of mud. 2 broods/season, 4-5 eggs per brood, eggs are white with brown markings, incubation from 13-17 days.
Migration: Barn swallows are migrators. In spring, they’ll migrate north into the US and Canada for breeding and to raise their young. When fall comes, they’ll head south to Mexico’s southern states. That said, they do maintain a year-round range in central Mexico where they remain for every season.
Appearance: The belted kingfisher is a large 13″ long bird with a large head, long bill, and stocky body. Blue/gray throughout with white ring around neck and white chest. The Female is the same but with an additional chestnut band on her chest.
Diet: Large 13″ long bird with a large head, long bill, and stocky body. Blue/gray throughout with white ring around neck and white chest. The Female is the same but with the additional chestnut band on the chest.
Feeder food: Unlikely to come to the feeder but often attracted to yards with streams or ponds.
Habitat: Near streams, rivers, ponds, lakes, and calm marine waters – especially unclouded water with little vegetation.
Nesting: Belted kingfishers dig burrows along the water’s edge for their nest. 1-2 broods/season, 5-8 eggs/brood – large white glossy eggs (1.5″ long), 22-24 days incubation.
Migration: Many but not all belted kingfishers are migrators. In spring, the migrators will head north into Montana, North Dakota, northern Minnesota, Canada, and Alaska to breed and raise their young. When fall comes the migrators head back south – as far south as Arizona, New Mexico, southern California, and Mexico.
Year-round range: All US states (except North Dakota and Arizona) and the pacific coast of Canada’s British Columbia.
Breeding range: While some stay in their year-round range, many others migrate north into Montana, North Dakota, northern Minnesota, Canada, and Alaska to breed and raise their young. When fall comes the migrators head back south – as far south as Arizona, New Mexico, and southern California.
Winter range: While many belted kingfishers migrate south for winter, just as many remain in their year-round range when the temperatures dip.
Appearance: Black-throated blue warblers are small birds about 5″ long, midnight/steel blue back, black throat, and a white belly
Diet: Insects and fruit.
Feeder food: Suet, peanut butter, and nectar.

Migration: In general, blue jays are not migrators. They remain in their year-round range for all 4 seasons – even during the breeding season. While they may move within their year-round range, they do not regularly head north for breeding and south for winter as some species do. That said, in rare cases, some will head west of their year-round range for the winter.
