Tensile Strength of the Eggshell Membranes
Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2016 The mechanical behaviour of eggshell membranes under tensile loading has been studied. Samples from different bird species (hen, goose and Japanese quail) have been used. Samples were cut out of the membrane in latitudinal direction.

Determinants of eggshell strength in endangered raptors
Journal of Experimental Zoology Part A: Ecological Genetics and Physiology, 2009 AbstractWe compared eggshell strength in a group of falcon taxa including the peregrine falcon (Falco peregrinus peregrinus), the red shaheen falcon (F. peregrinus babylonicus), the saker falcon (F. cherrug), the gyr falcon (F. rusticolus) and some interspecific and intraspecific hybrids.
