There are several bird nests around our yard about which I know. I visited each of them early this morning.
Mallard duck (on the ground in nook of front foundation) - Mama was not on nest, total of 5 eggs, 3 eggs broken up. Ferel cat that hangs about our yard may/may not be a factor.
Addition of 5/2/2013 - After not seeing the hen on her nest all day, yesterday, I took a closer look. It appears that there were a total of 6 eggs, 5 of which seemed to have hatched ducklings. (Thanks to HH for suggesting the possibility. I was so convinced that the nest had been there for only a couple of weeks that the possibility had not occurred to me. Duh!) A neighbor had told me of seeing a mama and several fuzz balls cross the street at her house (the most likely crossing that the mama would use to get her ducklings to the pond across the street) and I am now convinced that she saw "our" ducklings!
House finch (in miniature swing hung near ceiling of front porch) - Nest has seemingly been abandoned for the past two weeks.
Unknown (in bluebird box in back yard about 20 yeards from house) - A nest has been built within the past week, no eggs. It doesn't look like a bluebird nest to me, but we have seen a male bluebird sitting atop of the house on two or three days. Of course, we've also seen a red-shouldered hawk sitting there and I'm pretty sure it is not a hawk nest!
Red-shouldered hawk (about 10 feet below tip-top of old walnut tree, near the creek, in the woods) - Mama sitting on nest. I don't have a vantage point to detect any little heads. We have suspected that the nest was there for the past couple of weeks, at least; but, I had not gone back to check it out.
First-of-Season (FOS) Sightings
FOS (for our yard) birds hanging about during my inspection tour included an orange-crowned warbler and a couple of house wrens. Over-flying were FOS for our yard: cattle egret, little blue heron.
