It’s Sialia sialis in Latin, Eastern Bluebird in English. It is the blue model of bird amazing. First amazing bluebird fact; biologists recognize 8 other subspecies of the Eastern Bluebird. Second amazing bluebird truth, bluebird eyesight is phenomenal. A perched bluebird can spot its insect prey up to 130 feet distant. That’s 40 yards, nearly midfield on a 100-yard football field. But, there is a spring behavior that astonishes.
It’s about laying eggs. Yes, all birds lay eggs. Virtually all songbirds lay one egg per day, and usually early in the morning. What astonishes this writer is the fact that a pine bird house in our garden is the site of a bluebird nest. She laid the first pale blue egg, in her nest of fine grass Tuesday, May 9th. It a delight to check the box the next day, May 10th and find the second egg. A noontime check each day after revealed one more egg. On May 14, Mother’s Day Sunday, she laid the 6th and final egg.
She began to incubate them on May 15, Monday. She begins incubation after all eggs are laid, so they will all hatch 14 days later. That should be Monday, May 29. If my observations are accurate.
She has begun a vigil. She will not turn from it. Her body heat will cause the fertilized eggs beneath her to develop into little bluebirds. During her 14 day nest sit the male will sometimes bring her an insect. He will always keep sentry duty. He is her eyes and ears to the world outside the nest.
Bird amazing is an everyday event. Human eyes in every inhabitable spot on earth watch and appreciate the wonder in birds. Backyard bluebirds are high on my list right now. How did such wonder find its way into every bird species on earth? There is too much that is unique and astonishing to have organized over time. From migration, feathers, bird song, nests, eggs, and much more, the hand of God is visible.
Oh, the depth of the riches of the wisdom and knowledge of God! How unsearchable his judgments, and his paths beyond tracing out! Romans 11:33
