The mangrove swallow (Tachycineta albilinea) is a
bird in the
swallow family that breeds in coastal regions of
Mexico and
Central America. It is a
seasonal breeder and is
territorial when breeding, much like the related
tree swallow. Its nests are frequently found near water, no more than 2 metres (7 ft) above the ground. It usually forages close to the nest when feeding its chicks, but will go much further when foraging for itself. In between foraging attempts, it perches near water. It subsists primarily on a diet of flying
insects, including
dragonflies and
bees, unusually large prey for a bird of its size. It has blue-green upperparts, white underparts, a white streak above the eye, and blackish
flight and tail feathers. This swallow's song is a soft trilling, with a rolled jeerrt call, and a sharp alarm note. With a slowly decreasing population of at least 500,000 individuals, the mangrove swallow is classified as a
species of least concern by the
International Union for Conservation of Nature. (

The South Africa women's national cricket team has played five Test matches since 1997, and 71
Twenty20 Internationals (T20I) since their first such contest in 2007. The
team has represented South Africa in international
women's cricket since 1960, when they
hosted England, contesting four
Test matches. Their next officially recognised series was against
New Zealand, more than eleven years later. In 1977, they were excluded from competing in international sporting events, when the
Commonwealth of Nations signed the
Gleneagles Agreement as part of the international campaign against
apartheid. Although the men's national team returned to international cricket in 1991, the women's team did not compete again until 1997, when they toured Ireland and England. Since then, the team has played regularly in
One Day Internationals. South Africa have played four different sides in women's Test cricket, with
England their most frequent opponent, having faced them in six Tests. South Africa have similarly faced England more times than any other team in women's One Day International cricket. (Full list...)
A micrometer is a device incorporating a calibrated
screw, widely used for precise measurement of components in
mechanical engineering and
machining. Micrometers are usually, but not always, in the form of
calipers (opposing ends joined by a frame). The spindle is a very accurately machined screw and the object to be measured is placed between the spindle and the anvil. The spindle is moved by turning the ratchet knob or thimble until the object to be measured is lightly touched by both the spindle and the anvil.
