Through out natural history there have only been four groups of animals which have taken to the air.

The insects, pterosaurs, birds and bats are the only animals which have evolved the art of flight. It is still not fully understood why birds evolved the ability to fly. Besides one of the obvious benefits of escaping danger, as this African Monarch butterfly demonstrates, by flying away from the terminal penetration of the Assassin Bugs proboscis.

For me it is always rewarding to watch the swallows in flight. The swallows and martins belong to the family known as Hirundinidae and have a global representation of about 74 species. Of this 16 species breed within the confines of southern Africa. 13 of these species are considered to be endemic to the Afrotropical region, only 3 of those species are thought to be endemic or near endemic to the South Africa region.
One common specie easily observable is the Barn Swallow Hirundo rustica.
For a small bird they have an impressive travel record and may travel around 12 000km in as little as 30 days. A huge achievement, when one considers they only weigh between 13 and 20 grams.
The majority of the time they are found flying around feeding mainly on flying insects. It is here in the air when they are feeding that they never cease to amaze me with their incredible powers of flight. They resemble small fighter jets tearing through the sky, after their insect quarry, and pulling off incredible maneuvers which would render any fighter pilot into “black out” mode.
Due to good rains most of yesterday and a sunny warm morning today, condition were perfect for a spectacular air show.
