This is the second nest of a pair of Cardinals that live in my garden this year. This nest is in a potted lemon tree in my courtyard under the eaves and is protected from the weather. Can you identify the white egg?
Thank you for your comment. I agree that it’s not cowbird. Their eggs have always looked like these through the years. I like your thought that it may lack pigment.
I’m not sure, but maybe it’s any of these birds: goldfinch, bluebird, or a sparrow.
Thank you for your comment. Would a sparrow share a nest?
Cowbird probably.
Cowbird eggs have brown speckles. None of these eggs look like cowbird eggs. Sometimes eggs lack pigment.
