Spanish Imperial Eagle
The Spanish imperial eagle (''Aquila adalberti''), also known as the Iberian imperial eagle, the Spanish eagle or Adalbert's eagle, is a species of eagle native to the Iberian Peninsula. The binomial commemorates Prince Adalbert of Bavaria. Due to its distinct "epaulettes", old literature often referred to this species as the white-shouldered eagle. Formerly, the Iberian imperial eagle was considered to be a subspecies of the eastern imperial eagle, but is now widely recognised as a separate species due to differences in morphology, ecology, and molecular characteristics. Description This is a large raptor and quite large eagle, broadly similar in size to its cousin, the eastern imperial eagle, which is found in a considerably different distributional range. Compared to sympatric largish booted eagles, it is somewhat smaller than the golden eagle and somewhat larger than the Bonelli's eagle. Spanish imperial eagle can weigh from . The average weight of males in a sample of ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   [Amazon] |

He was educated at University of Jena to be ordained as minister at Renthendorf in 1813 where he remained until his death on 23 June 1864. He wrote ''Beiträge zur Vogelkunde'' (1820–22), which described 104 species of German birds in minute detail, and ''Handbuch der Naturgeschichte aller Vögel Deutschlands'' (1831) which described 900 bird species. Brehm accumulated a collection of 15,000 birds until his death, which included samples from his son, Alfred Brehm. Alfred collected these birds from Sudan, Egypt, and throughout Europe. He offered these to the Natural History Museum, Berlin, Berlin Zoological Museum in March 1835 because he feared that a storm would destroy his house, but the sale fell through. After his death, ...

Dihedral (aeronautics)
Dihedral angle is the upward angle from horizontal of the wings or tailplane of a fixed-wing aircraft. "Anhedral angle" is the name given to negative dihedral angle, that is, when there is a ''downward'' angle from horizontal of the wings or tailplane of a fixed-wing aircraft. Dihedral angle has a strong influence on dihedral effect, which is named after it. Dihedral effect is the amount of roll moment produced in proportion to the amount of sideslip. Dihedral effect is a critical factor in the stability of an aircraft about the roll axis (the spiral mode). It is also pertinent to the nature of an aircraft's Dutch roll oscillation and to maneuverability about the roll axis. Longitudinal dihedral is a comparatively obscure term related to the pitch axis of an airplane. It is the angle between the zero-lift axis of the wing and the zero-lift axis of the horizontal tail. Longitudinal dihedral can influence the nature of controllability about the pitch axis and the ...
