Our bluebird usually lays 2 or 3 eggs so when I noticed only one offspring, I checked around the nest and found an egg with a pecked hole in it. I’m guessing the pesky house sparrow was the culprit as we witnessed fierce battles over the box earlier this spring. I caught the male sparrow sneaking into the hole so he is the main suspect. But maybe it was a chickadee that hung around the box. House wrens can be a problem but couldn’t be the culprit as none are in our area. Sadly, the bluebirds won the war but lost an offspring.
Our sole survivor from the nest has fledged and has transitioned to nearby woods with his parents. It’s old enough now to accompany the adults back for morning treats of mealworms. Poor little thing has a lot to learn. He must learn quickly how to feed himself and stay safe. And, alas, there is a new predator cat in the neighborhood that I have chased off numerous times. Stay safe, little one…
We now hear the adult bluebirds singing territorial songs, patrolling the area, and both chasing off any bird that ventures into their space. We’re watching them as they gather pine straw for a new nest in the box…. so preparations are well underway for the next brood..
Such excitement in the avian world!
