Electron microscopical observations of psittacine beak and feather disease in an Umbrella cockatoo (Cacatua alba).
Psittacine beak and feather disease (PBFD) was diagnosed in an umbrella cockatoo (Cacatua alba) with severe feather dystrophy and loss. Electron microscopically, the intranuclear and intracytoplasmic inclusion bodies observed by light microscopy were composed of viral particles forming paracrystalline arrays, whorls, semicircles or concentric circles. Recovered viral particles from the skin and...
متن کاملLow speed maneuvering flight of the rose-breasted cockatoo (Eolophus roseicapillus). II. Inertial and aerodynamic reorientation.
The reconfigurable, flapping wings of birds allow for both inertial and aerodynamic modes of reorientation. We found evidence that both these modes play important roles in the low speed turning flight of the rose-breasted cockatoo Eolophus roseicapillus. Using three-dimensional kinematics recorded from six cockatoos making a 90 degrees turn in a flight corridor, we developed predictions of iner...
متن کاملNOTES ON SOME SPECIES OF THE GENUS EUPHORBIA IN IRAN
During the study on newly collected and herbarium specimens belonging to the genus Euphorbia, three species, namely, E. gorenfloti, E. cheirolepioides and E. splendida were found to be synonymous with E. chamaepeplus, E. grossheimii and E. decipiens, respectively. Euphorbia sahendi as an interesting and rare species has been recognized after long time again among my material and Euphorbia delto...
متن کاملUnilateral evisceration of an eye following cornea and lens perforation in a sulfur-crested cockatoo (Cacatua galerita).
A 24-year old male sulfur-crested Cockatoo (Cacatua galerita) was presented with a subacute perforation of the cornea without involvement of the lens. The bird was treated conservatively and the eye remained quiescent up to a second traumatic corneal perforation associated with a lens capsule rupture 15 months later. Due to the second perforating trauma of an already blind eye involving the len...
متن کاملLow speed maneuvering flight of the rose-breasted cockatoo (Eolophus roseicapillus). I. Kinematic and neuromuscular control of turning.
Maneuvering flight has long been recognized as an important component of the natural behavior of many bird species, but has been the subject of little experimental work. Here we examine the kinematics and neuromuscular control of turning flight in the rose-breasted cockatoo Eolophus roseicapillus (N=6), testing predictions of maneuvering flight and control based on aerodynamic theory and prior ...
