Abstract

The prenatal environment plays a crucial role in the development of both humans and non-human animals. Researchers have demonstrated the importance of prenatal factors in humans, such as in the development of speech and in the development of taste preferences. In birds, the study of prenatal development is enhanced because their development takes place in an egg and their eggshells can be preserved. The primary focus of this study was on the American crow (Corvus brachyrhynchos). I worked with the Western Foundation of Vertebrate Zoology in Camarillo, which is known for having one of the largest eggshell collections in the world. I measured the length and width of a total of 96 crow eggs, which consisted of 19 clutches. Rater reliability, the correlation between the length and width of the eggs, and the differences between clutches was analyzed. The results displayed high rater reliability, statistically significant differences between the clutches, and a statistically significant positive correlation between egg length and width. The significance of the results and future directions are discussed.
