But the bird in the video is an adult male "whiteface", a colour variation that originally popped up in Holland in 1969, and became the seventh colour variation that was established in captive cockatiels.
The bowling attack, with the left-arm angle of Ryan Sidebottom and the combination of Graeme Swann's off-spin with Yardy's slow left-arm, had a balance and variation that was obviously at odds with some of the more staid sides.
The index of condition exhibited longitudinal variation that was associated with the location of major urban areas along each river.
Therefore, we apply a Wiener filter to reintroduce some short-term variation that was present in the original reverberant observations y but was removed by the smoothing.
Measured ρg exhibited significant longitudinal variation that was consistent with previously observed longitudinal patterns (Chan et al. [2012]; Cown and McConchie [1982]).
Nevertheless, our results suggest that, at 13 of the total 24 sites, the differences in thickness during 2005 and 2008 surveys were within the range of the local variation that was measured during the 2008 survey (Figs. 1 and 6).
The first principal component explained 74% of the variation that was mainly loaded by different temperature variables and altitude while the second principal component explained additional 23% mainly loaded by precipitation variables.
Conclusion: Considerable variation that was not attributable to limitations of the measuring technique that was used occurs in the size and configuration of the urethral support structures in nulliparous asymptomatic women.
But across the range of variation that was observed, heart disease rates did not vary.
Using the Genbank sequences to analyze the clade-defining region [32], the marked variation that was detected in the pspA gene sequence correlated with a different clade designation.
Nevertheless, some of the variation that was represented by isolated base pair differences could also have been derived from point mutation events.
