A member of the grouse family, adult males are roughly the size of a turkey and, unlike the bullet-like speed of its smaller cousin the red grouse, it has a slower, more ungainly style of flight.
While historically thought of as simple, leathery structures composed of skin, research has since shown that the wing membranes of pterosaurs were highly complex and dynamic structures suited to an active style of flight.
Wing planform is highly diagnostic of flight style in extant animals [85], but controversy over the shape of the pterosaur brachiopatagium has resulted in multiple interpretations of azhdarchid flight style.
The sample size here was relatively small (n = 34) compared to the sample sizes (n = 306) used to investigate the scaling of ta [1], which precludes any analysis of flight style
Different styles of argumentation, flights of rhetorical fancy, numerous puns, intertextual allusions, un-sourced citations, and overt appeals to faith all compete for the reader's attention.
Accordingly, extrapolation of flight styles between avian species is relatively meaningless above the tightest taxonomic levels: recognising this, Sato et al. [17] state that their extrapolations apply to 'phylogenetically similar species' (p. 4), suggesting their conclusions can only apply to procellariiforms or, perhaps, animals that are highly convergent with procellariiforms.
The peregrine falcon has the additional advantage of a natural flight style of circling above the falconer ("waiting on") for game to be flushed, and then performing an effective and exciting high speed diving stoop to take the quarry.
The model can be extended to include the pleiotropic effect of QTL on both the magnitude and shape of power curves and the physical structure, body mass and flight style of birds (7).
He worked hard last week with Butch Harmon, his coach, to perfect the shots he will need at Valhalla, which requires a much higher ball flight than the British Open, where the wind and links style of play required lower ball flight.
For some his documentary-style re-enactment of the hijacking of flight United 93 was the best film of last year, albeit one of the most harrowing.
Three-dimensional time-of-flight.
