HOW ‘BOUT THIS? A CLUTCH OF SIX WHITE BLUEBIRD EGGS!


EGG-CITE FOR WHITE!

WHITE BLUEBIRD EGGS? It happens. Approximately 5% laying female bluebirds are missing the pigment gene to color the eggs blue as they pass through her oviduct. The eggs are just as fertile, generally, as the blue ones.  Note the slightly pinkish hue.  I’ve seen them before actually pure white.  When I first saw those feathers, I thought Tree Swallows.  But no, they are bluebirds.  There are not enough of the right feathers for TRES and I saw the pair in the tree above me anyway.   To read up more about white bluebird eggs, here is a great page for that: http://www.sialis.org/whiteeggs.htm

White Bluebird Eggs

  1. I have had a bluebird box for years. This year we got our first white eggs. I thought some other bird made a home in there. I watched and sure enough its a Bluebird. (only 2 white eggs). Usually we get 4 to 5 blue eggs. I live in Central Virginia.
