The barn swallow is a small bird with a distinctive appearance. It measures about 7 inches in length and has shiny steel-blue feathers on its back. Its forehead and throat are chestnut in color, while its underparts are a rusty-orange shade. One of its noticeable features is its long forked tail, which has a white base. It’s worth noting that the female barn swallow has lighter coloring and a shorter tail compared to the male.
When it comes to their diet, barn swallows primarily feed on insects, with a preference for beetles, wasps, and flies. They have a unique way of getting a drink by skimming the surface of the water, but they are not typically seen visiting bird feeders.
These birds are commonly found in open fields and pastures, where they build their nests. Barn swallows prefer manmade structures such as barns for nesting. They construct their nests using mud. During the breeding season, they produce two broods, each containing 4-5 white eggs with brown markings. The incubation period for these eggs ranges from 13 to 17 days.
Barn swallows are migratory birds. In the spring, they migrate north to the United States and Canada to breed and raise their young. When autumn arrives, they head south to the southern states of Mexico. However, some barn swallows remain in central Mexico throughout the year, maintaining a year-round range there.
Belted Kingfisher (Crested Bluebirds In Florida)
- Scientific name: Ardea alba
- Lifespan: 15 years
- Size: 3 feet
- Native to: Asia, Africa, the Americas, and southern Europe
The belted kingfisher is a relatively large bird, measuring about 13 inches in length. It has a distinctive appearance with a large head, a long bill, and a stout body. The bird is predominantly blue-gray in color with a white ring around its neck and a white chest. However, the female belted kingfisher is similar in appearance to the male but features an additional chestnut band on her chest.
When it comes to their diet, belted kingfishers primarily feed on fish. They are not commonly seen at bird feeders but are often attracted to areas with streams or ponds.
These birds are typically found in habitats near bodies of water, including streams, rivers, ponds, lakes, and calm marine waters, especially those with clear water and minimal vegetation.
For nesting, belted kingfishers dig burrows along the water’s edge. They usually have 1-2 broods per season, each containing 5-8 large, glossy white eggs that are about 1.5 inches long. The incubation period for these eggs lasts for approximately 22-24 days.
Belted kingfishers are known for their migratory behavior, although not all of them migrate. In the spring, migratory individuals head north to places like Montana, North Dakota, northern Minnesota, Canada, and Alaska for breeding and raising their young. When fall arrives, these migratory birds head back south, sometimes as far as Arizona, New Mexico, southern California, and Mexico.
While many belted kingfishers migrate, some choose to stay in their year-round range, which includes all U.S. states except North Dakota and Arizona, as well as the Pacific coast of Canada’s British Columbia. During the winter, some remain in their year-round range, while others continue their migration south to escape the cold temperatures.
- Scientific name: Cyanocitta cristata
- Lifespan: about 7 years
- Size: 9 and 12 inches
- Native to: North America
The blue jay is a large bird, measuring about 12 inches in length. It has a medium blue and white body with distinctive features like a blue crest on its head, which it can flatten at will. The bird also sports a gray belly and a white face. Its wings are a combination of white and blue with noticeable black spots. Interestingly, both male and female blue jays share the same appearance.
When it comes to their diet, blue jays are omnivorous, which means they eat a variety of foods. They enjoy insects, fruits, seeds, nuts, and they are not averse to consuming other birds’ eggs and nestlings.
For those interested in attracting blue jays to their yards, offering whole peanuts, sunflower seeds, and cracked corn can be enticing.
Blue jays are quite adaptable when it comes to their habitat. They are commonly found in forested areas with mixed types of trees, but they are also a frequent sight in suburban and urban environments.
When it comes to nesting, blue jays build substantial nests made from twigs, bark, and mud, typically resting on tree branches at heights ranging from 5 to 50 feet. During the breeding season, they tend to have 1-2 broods, and each brood can contain 2-7 eggs. The eggs of blue jays vary in color from pale blue to a light brown base, often adorned with brown or gray spots. These eggs are relatively small, measuring about 1 inch by just under 1 inch. Both parents share the responsibility of incubating the eggs, which takes about 17-18 days. The young birds, or fledglings, typically leave the nest between 17 to 21 days after hatching.
Blue jays are known for being non-migratory birds. They tend to stay within their year-round range throughout all four seasons, including the breeding season. While they may move around within this range, they do not have a regular pattern of migrating north for breeding and south for the winter, as some other bird species do. However, in rare instances, some blue jays may venture west of their year-round range during the winter months.
Blue-gray Gnatcatcher (Small Bluebirds In Florida)
- Scientific name: Polioptila caerulea
- Lifespan: 3-4 years

However, during the breeding season, the male may have narrow black eyebrows that accentuate its features.
When it comes to their diet, blue-gray gnatcatchers primarily feed on insects and spiders, which they catch as they dart through the air.
These birds are not commonly seen visiting bird feeders. They tend to prefer foraging for insects in their natural environment.
Blue-gray gnatcatchers are typically found in deciduous forested areas, where they make their nests and raise their young.
For nesting, they create tidy cup-shaped nests using natural fibers, bark, and spiderwebs. These nests can be situated at heights ranging from 3 to 80 feet in trees or shrubs. During the breeding season, they usually have 1-2 broods, with each brood consisting of 3-5 pale blue eggs with red or brown spots. The eggs are quite small, measuring between 0.5 to 0.6 inches by 0.4 to 0.5 inches. The incubation period lasts for approximately 11-15 days, and the young birds, or fledglings, typically leave the nest at around 10-15 days old.
Blue-gray gnatcatchers exhibit migratory behavior. While some of them stay within their year-round range during spring and summer, most migrate north into the United States to breed and raise their young. In the fall, these migratory individuals head back south, returning to their year-round range or even traveling further south along the Mexican Pacific coast, southern Florida, and the Caribbean islands to spend the winter.
Their year-round range includes the southernmost parts of several U.S. states, such as California, Arizona, New Mexico, Texas, Louisiana, Georgia, Mississippi, Alabama, Florida, South Carolina, North Carolina, and Virginia.

These birds are adaptable when it comes to their habitat, and they are commonly found in fields with scattered trees, open woodlands, farmlands, and marshes. It’s not uncommon to spot common grackles in suburban yards as well.
For nesting, common grackles construct bulky cup-shaped nests made of twigs. They typically place these nests at heights ranging from 3 to 20 feet in conifer trees. Their nests usually contain 3-5 eggs, which are incubated for about 12-15 days. The young birds, or fledglings, typically leave the nest at around 12-15 days old.
Common grackles exhibit migratory behavior. While some remain within their year-round range throughout all four seasons, many migrate north in the spring, venturing as far north as Canada’s Northwest Territories to breed and raise their young. Then, when fall arrives, they head back south into their year-round range. A small portion of the population pushes even further southwest into Texas.
Their year-round range includes Nebraska and the U.S. states located south and east of it. Their breeding range extends to regions such as Montana, Idaho, Wyoming, Colorado, New Mexico, North Dakota, South Dakota, Kansas, western Kansas, Minnesota, Wisconsin, Michigan, the New England states, and all Canadian provinces (except for Nunavut and British Columbia).

Eastern bluebirds are often found in wide-open spaces, including fields and meadows, where they make their homes and raise their young.
In terms of nesting, eastern bluebirds are cavity nesters. The male bluebird takes on the task of selecting the nest site, which could be an old woodpecker hole in a tree or a manmade nestbox. However, it is the female who is responsible for building the nest. Interestingly, she may reuse the same nest for multiple broods. During the breeding season, they tend to have 2-7 broods, each containing 4-5 pale blue (sometimes white) eggs with no blemishes or discoloration. These eggs are relatively small, measuring about 0.9 inches by 0.8 inches. The incubation period for these eggs typically lasts from 11 to 19 days.
While many eastern bluebirds remain within their year-round range throughout the entire year, some exhibit migratory behavior. These migratory bluebirds head north for breeding and raising their young and then travel south during the winter months. They either return to their year-round range or move further west into regions like Colorado, New Mexico, and western Texas.
