Glare Reduction by Dark Facial Markings and Bills in Birds
<p>Avian facial plumage, bill coloration, and feather microstructure may serve one or more adaptive functions. Several researchers have proposed that dark eyestripes, bills, and facial masks aid in reducing glare, however, there have been relatively few tests of this hypothesis. Dark facial …

Are there structural differences in the flight feathers among Procellariiformes related to the use of wings for underwater propulsion?
… if there are differences in the flight feathers of seabirds that use their wings for both underwater and aerial propulsion and seabirds that only use their wings in air. The study was restricted to the order Procellariiformes because of the wide range of divers and non-divers. I sampled …

Exploring plastron stability and fluid friction reduction on robust micro-textured non-wetting surfaces
… can be varied from a corpuscular or spherical microstructure to a beads-on-string structure and finally to bundled fibers by controlling the solution concentration c and molecular weight M of the sprayed polymer solution. A scaling law is proposed that relates the minimum necessary …
