The Apodiformes diversified during the Eocene, at the end of which the extant families were present; fossil genera are known from all over temperate Europe, between today's Denmark and France, such as the primitive swift-like Scaniacypselus [5] (Early–Middle Eocene) and the more modern Procypseloides (Late Eocene/Early Oligocene – Early Miocene). A prehistoric genus sometimes assigned to the swifts, Primapus (Early Eocene of England), might also be a more distant ancestor.

Swifts and Us by Sarah Gibson | Waterstones

Swifts live in perpetual summer. They inhabit the air like nothing else on the planet. They watched the continents shuffle to their present positions and the mammals evolve. They are not ours, though we like to claim them. They defy all our categories and present no passports as they surf the winds across the world. They sleep in the air, their wings controlled by an alert half-brain. Yet for all their adaptability and longevity swifts have recently been added to the UK’s Red List of endangered birds. A Risca Boy’s Birds by Jeremy Hughes I joined the RSPB’s Young Ornithologists’ Club, and dog-eared its magazine articles about this habitat and that habitat and the wonders of its reserves. There are a few things to look for that can help you sort through the innumerable Swift books on the market. del Hoyo, Josep; Elliott, Andrew; Sargatal, Jordi; Christie, David A.; de Juana, Eduardo (eds.).

The swiftlets or cave swiftlets have developed a form of echolocation for navigating through dark cave systems where they roost. [13] One species, the Three-toed swiftlet, has recently been found to use this navigation at night outside its cave roost too.Piper, Ross (2007), Extraordinary Animals: An Encyclopedia of Curious and Unusual Animals, Greenwood Press, Swifts live almost entirely in the air. They eat, drink, sleep, mate and gather their nesting materials on the wing, fly thousands of miles across the world, navigating their way around storms, never lighting on tree, cliff or ground, until they return home with the summer.

[1]Swifts occur on all the continents except Antarctica, but not in the far north, in large deserts, or on many oceanic islands. [14] The swifts of temperate regions are strongly migratory and winter in the tropics. Some species can survive short periods of cold weather by entering torpor, a state similar to hibernation. [13] As well as presenting the author's original research, this book also brings together a review of all current research into the identification and distribution of 96 species of swift worldwide."

The programming language itself does combine familiar elements, but until I know exactly what it can do, I can't judge the programming language itself.

The second edition of this highly acclaimed book has been extensively revised by the author to take account of recent information, most particularly about the neotropical swifts, and several plates have been revised by the artist.
