Lloyd's production keeps the action flowing smoothly on Soutra Gilmour's unitary set and, in a 14-strong cast, there are good performances from Anthony O'Donnell as a Marxist butler, Ron Cook as Jack's vindictive uncle and Kathryn Drysdale as a false Marguerite Gautier, while Paul Leonard and Forbes Masson are especially funny as a pair of feather-hatted Tory ladies.
CORRECTION: A caption for a photograph previously included in this article misidentified a pair of feathers as eagle feathers.
The centrifugal moult is modified in the tail feathers of woodpeckers and treecreepers, in that it begins with the second innermost pair of feathers and finishes with the central pair of feathers so that the bird maintains a functional climbing tail.
The outer edge of each tail feather is fringed with grey near the base and the outer pair of feathers have a narrow white border on the inner edge.
This table gives the number of growing feathers at every position, the number of nodal feathers, the number of terminal feathers, and the number of each of the three directionality scores for each adjacent pair of feathers where one or both were growing.
And the pairing of feather-light cotton T-shirts with two-tone pinstripe jackets and pocket chains showed that sophistication and street can play nicely together.
The tail is short and square, with white patches near the tips of all but the central and outermost pairs of feathers.
These martins are 12 15 cm (4.7 5.9 in) long with drab brown or grey plumage and a short square tail that has small white patches near the tips of all but the central and outermost pairs of feathers.
The pale crag martin of the nominate subspecies P. o. obsoleta is 12 13 cm (4.7 5.1 in) long with light brown upperparts, becoming paler on the lower back, and a short square tail that has small white patches near the tips of all but the central and outermost pairs of feathers.
The rock martin of the nominate subspecies P. f. fuligula is 12 15 cm (4.7 5.9 in) long with earth-brown upperparts and a short square tail that has small white patches near the tips of all but the central and outermost pairs of feathers.
In species where several adjacent feathers grow simultaneously, it may be desirable to limit directionality scoring to adjacent pairs of feathers that are both growing because these pairs will almost always be part of the same molt series.
