Egg Characteristics of Female Common Terns Are Repeatable, and Vary With Maternal Age and Laying Order We investigated sources of variation in eight egg characteristics capturing the colour, spottiness, shape, and size of 1589 eggs from 687 clutches produced by 330 female common terns (Sterna hirundo)...

Do you never ask if a female #bird always lays #eggs of a certain appearance? We tried do answer this question in the common terns. Follow the link for more:

New paper!
Legacy and emerging #PFAS in eggs of yellow-legged gulls from Marseille, France.
PFOS was the most abundant legacy compound.
Emerging PFAS were detected in most eggs.
