In this article, we'll delve deep into the enchanting world of these avian wonders, revealing the five species renowned for their bright blue eggs.

• Nesting: Robins build their nests in trees, shrubs, or even on human-made structures like ledges or gutters.
• Clutch Size: A clutch typically contains 3-5 eggs, though occasionally more.

The Eastern Bluebird

Sialia sialis:

Their Eggs:

• Color: Their eggs, too, are a soft blue, matching the male's plumage.

The Western Bluebird

Sialia mexicana is another western beauty:

The European Starling

Sturnus vulgaris isn't native to North America, but has become widely known:

• Color: Iridescent black with purplish-green sheen when feathers are in prime condition.

Their Eggs:

• Color: Starlings might surprise you with their glossy blue-green or pale blue eggs.
• Nesting: They are cavity nesters, often aggressively competing for birdhouses.

The Significance of Blue Eggs

Why do these birds lay blue eggs? Here are a few theories:

• Camouflage: The color blue might offer some camouflage against the sky, hiding the eggs from aerial predators.
• Parental Recognition: Some birds might recognize their own eggs by the unique color, reducing the risk of parasitism by species like cowbirds.
• UV Reflection: Blue eggs might reflect ultraviolet light, potentially signaling to the male that the nest is active and encouraging continued mating or territorial behavior.

Important Tips for Observing Blue Eggs:

• Respect Nests: When observing nests, do so from a distance or with binoculars to avoid disturbing the birds.
• Nest Boxes: Installing and maintaining nest boxes can encourage these species to nest nearby, offering a glimpse into their life cycle.
• Photography: Photography of blue eggs can be tricky due to the need to avoid using flash, which can scare away birds. Natural light is your friend here.

Common Mistakes to Avoid:

• Disturbing Nests: Touching or moving nests can cause birds to abandon them.
• Leaving Scraps: Human food can attract predators like raccoons or attract unwanted attention to the nest area.
• Over-Pruning: Removing too much vegetation near a nest can expose it to predators or the elements.
