Winter Plumages: Illustrated by the Rose-Breasted Grosbeak (Zamelodia ludoviciana)

Low 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...

Plumages of the Least Tern

Over the past five years, U.S. breeding colonies of the endangered California Least Tern (Sterna albifrons browni •) have been closely monitored throughout the nesting season (Atwood et al., 1977). One result of this close scrutiny has been the observation each year of a small number of birds in prebreeding or subadult plumages (in this discussion, the term subadult is used to represent any alt...

Low 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 ...
