Researchers ponder the shape of birds' eggs

https://phys.org/news/2017-02-ponder-birds-eggs.html

Paper: The point of a Guillemot's egg

http://onlinelibrary.wiley.com/doi/10.1111/ibi.12458/full

"In summary, in light of the failure of the rolling-in-an-arc hypothesis to account for the pyriform shape of Guillemot eggs, we offer two new hypotheses: strength, and protection from debris contamination."

Quantifying the demographic cost of human-related mortality to a raptor population

http://journals.plos.org/plosone/article?id=10.1371/journal.pone.0172232

"...the number of golden eagle pairs required to support windfarm mortality was large. We estimated that the entire annual reproductive output of 216-255 breeding pairs would have been necessary to support published estimates of 55-65 turbine blade-strike fatalities per year."
