Weavers with blue eggs2018-10-11 (826)
There are 18 species of weavers that usually only lay pure blue eggs. Blue or blue-green eggs are very widespread in birds generally, resulting from the predominant deposition of the pigment biliverdin (Walters 2006a). Many other weavers lay eggs with a variety of colours, so some individual females may lay pure blue eggs, while other individuals of the same species lay eggs of various colours and markings.
The list below includes two quelea, three fodies, two bishops, and 11 other weavers.
