Advice: What birds to expect. Print page 2 November 2009 The most likely visitors to your garden are starlings, house sparrows, blackbirds, blue and great tits, robins, greenfinches and collared doves.
In many gardens dunnocks, song thrushes and chaffinches will hop around on the ground below the bird table. In wooded areas you may be lucky enough to see great spotted woodpeckers, nuthatches and coal, marsh and long-tailed tits. Look out for blackcaps, too – they are becoming regular visitors to some bird tables in winter. Thrushes will visit your garden if there is fruit and berries for them to eat: fieldfares and redwings (winter visitors from Scandinavia between October and early April), plus resident mistle and song thrushes and blackbirds.
Feral ring-necked parakeets visit bird tables in south-east England and are spreading west and north. Bird Populations. Purpose To understand how scientists discern patterns and changes in bird populations.
Context In this lesson, students will study bird migratory patterns and the methods that researchers use to study them. Advice: Exterior barn owl boxes. Print page 26 August 2009 Exterior barn owl nestboxes can be fixed to trees or to the outside of buildings.
Where possible, they should face onto grassland and be reasonably conspicuous with an open flight path to them. They should not face into the prevailing wind. Although barn owl nests are usually well spaced out, placing boxes in pairs, from twenty to a few hundred metres apart, will provide a pair with roosting as well as nesting sites. Since many barn owls are killed by road traffic, it is best not to put up owl boxes close to motorways and main roads. Te Ara Encyclopedia of New Zealand. RC Airplane Control Surfaces. Ailerons Ailerons are roll-control control surfaces of the RC Airplanes.

Kite History of Thailand. The tradition of kite-flying in Thailand stretches back to the very birth of the nation.
Throughout the country's history the sport has been played by royalty and commoners alike. Its heritage is dignified by the time-honoured skills of kite-making and kite-flying, while competition rules and regulations have been long established. At its very least it is an age old national pastime; at its best it is Asia's most sophisticated form of competitive kite-flying. History of kite flying in Thailand. How to build an EPP foam RC airplane. World's First 3D Printed UAV Takes to the Skies « How-To News. The use of unmanned aerial vehicles (UAVs) has been widely used by the military for surveillance and reconnaissance missions—even armed combat.
But there are other beneficial applications of an unmanned aircraft, such as search and rescue operations, scientific exploration, locating mineral deposits, transporting goods and even filming bikini models. But drone development can be pretty pricey, unless you just happen to have a 3D printer... Engineers at the University of Southampton in England have "designed and flown the world’s first ‘printed’ aircraft, which could revolutionise the economics of aircraft design.
" The entire structure of their flying SULSA (Southampton University Laser Sintered Aircraft) drone has been fabricated using a 3D printer, specifically the EOSINT P730 nylon laser sintering machine, which can fabricate 3D objects out of plastic or metal, building them up layer by layer. LEGO 3D milling machine carves amazing 3D shapes out of foam. We’ve seen a lot of 3D printers lately, but it that doesn’t mean milling/CNC machines don’t have their place.
The latest one to get to our attention comes from Arthur Sacek from Brazil’s ZOOM Education for Life, a 13-year-old company that teams up with LEGO Education to develop innovative learning solutions. Sacek built a this wonderful device almost entirely using LEGO pieces–everything is made of LEGO except for the electric saw. The LEGO milling machine–basically the opposite of a 3D printer–takes a bit of time to produce the finished product.
As you can see in the video below, Sacek inserts a block of floral foam, the kind you see at the bottom of floral arrangements to keep everything together, and the printer goes to work, cutting away layer by layer. Since the layers of foam still sit on top of the original piece after the printer is done doing its thing, Sacek took a vacuum tube and sucked away all of the loose bits. Via The NXT Step.
