Several factors may drive bird nest‐site selection, including predation risk, resource availability, weather conditions and interaction with other individuals. Understanding the drivers affecting where birds nest is important for conservation planning, especially where environmental change may alter the distribution of suitable nest‐sites.

Reproduction in procellariiform birds is characterized by a single egg clutch, slow development, a long breeding season and obligate biparental care. Female Leach's Storm Petrels Hydrobates leucorhous, nearly monomorphic members of this order, produce eggs that are between 20 and 25% of adult bodyweight.

Numerical Investigation on Aerodynamic Performance of Bird’s Airfoils [PDF]
In this work, the aerodynamic performance of four types of bird’s airfoils (eagle, stork, hawk, and albatross) at low Reynolds number and a range of angles of attack during fixed (unflapping) gliding flight was numerically investigated utilizing open ...

A novel hypothesis for how albatrosses optimize their flight physics in real-time: an extremum seeking model and control for dynamic soaring [PDF]
The albatross optimized flight maneuver -- known as dynamic soaring -- is nothing but a wonder of biology, physics, and engineering. By utilizing dynamic soaring, the bird can travel in the desired flight direction almost for free by harvesting energy from the wind.

SI-traceable validation of a laser spectrometer for balloon-borne measurements of water vapor in the upper atmosphere [PDF]
Despite its crucial role in the Earth's radiative balance, upper-air water vapor (H2O) is still lacking accurate, in situ, and continuous monitoring.

The Sailing Flight of the Albatross [PDF]
IN NATURE, vol. xxxix. p. 230, the late Mr. William Froude, in a letter to Sir William Thomson, on the subject of the “Soaring of Birds,” gives a short account of the well-known and often discussed sailing flight of the albatross; and says that after long consideration the only explanation, which presented itself to his mind was, that the birds use the
