I plucked the outer right rectrix, thereby inducing the growth of a replacement. |

We also looked for evidence of multiple waves of rectrix replacement in the inner rectrices. |
|
Rectrices are numbered from R1, the innermost rectrix to R5, the outermost rectrix. |
|
Table 6 summarizes rectrix replacement for the 58 presumed adults that were growing rectrices. |
|
It is defined as the distance between the tip of the longest rectrix and the point at which the two central rectrices protrude from the skin. |
|
Three of these immatures were initiating rectrix molt, and all were replacing R5, the outermost rectrix. |
|
Apparently, rectrix replacement starts late enough in the first molt of primaries that the white fringing on the flight feathers has been lost in most birds before rectrix molt is initiated. |
|
Similarly the frequency and extent of tertial and rectrix replacement was greater in some species, particularly those that replaced more greater coverts. |

A luxurious facility on nearly 20 acres of airport property, Rectrix offers more than 180,000 square feet of aircraft hangars and passenger service facilities. |

He said Rectrix Aviation, the fixed-base operation that has been building a new hangar at the airport, could hold a ribbon-cutting within the next couple of months. |
