Bird eggs come in a variety of colors, shapes, and sizes. While many eggs are speckled or have vibrant colors, there are also birds that lay small, white eggs. Some examples include the Ruby-Throated Hummingbird, which lays two immaculate white eggs, and the American Robin, known for its bright blue-green eggs. Yellow Warblers and Blue Jays also lay small white eggs. These eggs are typically laid in clutches of 4 to 5 eggs for Yellow Warblers and 2 to 7 eggs for Blue Jays. Other birds that lay small white eggs include the Northern Cardinal, Cedar Waxwing, Baltimore Oriole, Osprey, Black-Capped Chickadee, and Sandhill Crane.
Key Takeaways:
- There are bird species that lay small white eggs.
- The Ruby-Throated Hummingbird, American Robin, Yellow Warbler, Blue Jay, and other birds lay small white eggs.
- Small white eggs can be found in clutches ranging from 2 to 7 eggs.
- The color, shape, and size of the eggs can help identify the bird species.

Identifying Birds by Their Eggshells
Bird eggshells are primarily made of calcium carbonate, giving them a default white color. However, bird species exhibit variations in their eggshell appearances, allowing for identification based on patterns and colors. Some birds lay pure white eggs, while others have unique markings or patterns on their shells.
For instance, the Eurasian collared-dove, American three-toed woodpecker, and blue-throated hummingbird lay pure white eggs with no discernible markings. On the other hand, birds like the American kestrel, house sparrow, and cave swallow lay white eggs with various markings and patterns.
The size and shape of the white bird eggs can also provide valuable information for identification. Generally, larger birds tend to lay larger eggs than smaller birds. Additionally, the shape of the egg can be influenced by the bird’s flying abilities or adaptations for nesting.
Examples of Birds and Their Eggshell Characteristics
Let’s take a closer look at some bird species and their eggshell characteristics:
| Bird Species | Eggshell Color | Markings or Patterns | Size |
|---|---|---|---|
| Eurasian Collared-Dove | Pure white | No markings | Medium |
| American Three-Toed Woodpecker | Pure white | No markings | Small |
| Blue-Throated Hummingbird | Pure white | No markings | Small |
| American Kestrel | White | Various markings and patterns | Small |
| House Sparrow | White | Various markings and patterns | Small |
| Cave Swallow | White | Various markings and patterns | Small |
The table above showcases examples of bird species and their eggshell characteristics. While some lay pure white eggs without markings, others exhibit distinct patterns and variations in eggshell colors. These characteristics aid in identifying different bird species and contribute to the overall diversity found in avian reproduction.
Nesting Habits and Egg Colors
The color of bird eggs can be influenced by their nesting habits. Different birds have distinct nesting preferences, leading to variations in egg colors. Let’s explore the fascinating relationship between bird nesting habits and egg colors.
Birds that build their nests in trees and shrubs: Some bird species, like dunnocks and blackbirds, prefer to build their nests in trees and shrubs. These birds often lay eggs that are blue or greenish in color. The eggs can be either spotted or unspotted, adding to the beauty and diversity of their nests.
Hole-nesting birds: Woodpeckers, owls, and other hole-nesting birds have distinctive nesting habits. These birds create their nests in tree cavities or burrows, providing excellent protection for their eggs. As a result, they tend to lay white or pale blue eggs that blend in with the nest’s surroundings. The subtle colors help camouflage the eggs from potential predators.
Birds that lay their eggs in the open and on the ground: Some bird species, such as plovers and gulls, choose to lay their eggs in open areas or on the ground. To increase their chances of survival, these birds have evolved to produce eggs with brown or speckled colors. The brown or speckled patterns provide effective camouflage, allowing the eggs to blend seamlessly with their natural surroundings.
Egg Color Variation Among Nesting Birds
The variation in bird egg colors is not limited to the nesting habits mentioned above. Within each nesting category, there can be further differences in egg colors and patterns. The colors can range from pale blue and green to brown and speckled, depending on the specific bird species and their unique evolutionary adaptations.
Here is a table showcasing some bird species and their nesting habits:
| Bird Species | Nesting Habit | Egg Color |
|---|---|---|
| Dunnock | Trees and shrubs | Blue or greenish |
| Woodpeckers | Hole-nesting | White or pale blue |
| Owls | Hole-nesting | White or pale blue |
| Plovers | Open areas and ground | Brown or speckled |
| Gulls | Open areas and ground | Brown or speckled |
| Bird Species | Egg Color | Markings |
|---|---|---|
| American Kestrel | White to pale brown | Spotted with brown and gray |
| House Sparrow | White to greenish-white | Faint spots or speckles |
| Cave Swallow | White | Finely spotted with brown and purple |
Birds with Small White Clutches
While some birds lay small white eggs, the number of eggs laid in each clutch can vary. Here are a few examples of bird species with small white egg clutches:
- Ruby-Throated Hummingbird: This tiny bird lays two eggs in each clutch, which are small and white. The female incubates the eggs for about 12-14 days.
- American Robin: These birds typically lay 3 to 4 small white eggs in each clutch. The eggs are incubated for about 12-14 days before hatching.
- Yellow Warbler: Clutches of 4 to 5 small white eggs are typical for this species. Incubation period lasts approximately 11-12 days.
- Blue Jay: These striking birds can lay clutches of 2 to 7 small white eggs. Incubation takes about 16-18 days.
Other bird species that tend to have small white clutches include the Northern Cardinal, Cedar Waxwing, Baltimore Oriole, Osprey, Black-Capped Chickadee, and Sandhill Crane. These birds lay clutches ranging from 2 to 7 eggs.
The table below provides a summary of the number of eggs typically found in the clutches of these bird species:
| Bird Species | Number of Eggs in Clutch |
