Garden visiting Green Finches

The greenfinch is the largest of a trio of British finches with partly green plumage (the others are the siskin and the rare serin). It is one of our more numerous birds, being well suited to our lowland countryside with its mosaic-like pattern of woods, farmland, hedgerows, thickets and gardens. 

The greenfinch is one of the most widespread and abundant visitors to bird tables in Britain and Ireland. It is sometimes disparaged by birdwatchers who are captivated by the acrobatic feats of the blue and great tits as they hang on to strings of nuts. The greenfinch being a relatively large finch is not a particularly acrobatic feeder although, in several areas, it has learned to feed on hanging nuts. Some people actually overlook its presence since it is similar in size to the ubiquitous house sparrow, and many greenfinches have rather little yellow or green on their plumage which strengthens the resemblance. The adult male greenfinch is a handsome bird, with brilliant yellow flashes on the wings and tail-most obvious when in flight and washes of green and greenish yellow over the rest of the plumage. The female and the young of either sex are less highly colored, with much brown streaked plumage like a sparrow’s. In recent years another much smaller finch, the siskin, has also taken to feeding in gardens, mostly at the end of winter, but there is little chance of the two being confused.

Habitat and Range

As with many of our garden and farmland bird species, greenfinches are naturally birds of the woodland edge, finding hedges in arable land, and shrubberies in parks and gardens, ideal places for breeding. They can be found over most of Europe, spreading into Asia in the east and to north Africa in the South, but they’re absent from the far northern parts of Europe and Asia, which lack trees of shrubs. Many areas in Britain have reported recent spreads in the breeding range and local increase in numbers. 

Seed Eaters

Greenfinches feed on seeds for almost all their lives. In the autumn the flocks of young birds, which are soon joined by the adults, may become very numerous, with some numbering in the thousands. These large flocks are sometimes seen feeding on ripening corn, gleaning the stubbles or feasting on weed seeds in root crops or on waste ground. Their weight generally precludes feeding from seeds still held on the plants, but they are adept at finding seeds on the ground. They can live well on open ploughed land, finding dormant seeds which may, in some cases, be several years old.   The weeds particularly favored include charlock, persicaria, groundsel, chickweed and fat hen. When a large flock has found a good feeding site, it is quite possible to hear the birds from thirty to forty years away not from their calls but from the cracking of seeds in their bills. All the food is first manoeuvred in the bird’s beak to remove the husk for greenfinches only eat the central nutritious part. 

Autumn and winter

The autumn flocks frequently contain other finch species, but during the evening the greenfinches tend to roost on their own. The roosting site is often a clump or rhododendrons, laurels or an old hedge with plenty of holly or ivy. The birds prefer roosting sites which are not particularly high but have plenty of thick cover. Ringing results have shown that the birds move regularly from roost to roost and that in general they are a mobile and nomadic species. There are not many indications of movements over 200 or 300 km within the British population, but many birds from the northern part of the European range travel 1000km or more each autumn and spring. In cold winter weather is not a serious threat to survival provided that the feeding grounds are clear of snow. If the weather is very cold and the day length is very short, they may find it difficult to take in sufficient food to see them through the night. In such circumstance and during snowy weather many more may join the flocks feeding in gardens. 

Human Help

Greenfinches visiting gardens take almost any sort of seed. Hemp, peanuts loose on the ground or hanging and particular sunflowers seeds are favorites. As with several species observed at feeding stations, the numbers seen at any instant in a garden are a tiny proportion of all the dividual birds using the site through whole winter. As many garden bird feeders know, the number of greenfinches seen in gardens a peak in March and April, and many are still present in early May. Ringing returns show that this is the period when more greenfinches die in the wild than at any other time of year. This is easily explained for the birds have ben exploiting a stock of seeds which has not been replenished naturally since the autumn. The food supply has thus run out, and continued feeding by people who put out food for birds in their gardens is particularly important.  

The Breeding Season

During the spring the males start to give their “dreeez” summer call. When displaying, they precede this by a rather weak, chattering song. Displaying males may sing and call from the top of a tree or bush, or may advertise their presence in a characteristic song flight. In most cases several pairs take up territories close together each male defending only a small area round the chosen nest site. The nest is built of twigs roots and moss in late April or early May, and is lined with fine grass roots, hair, wool or feathers. Four to six eggs are generally laid in each clutch and incubated for two weeks. The chicks are fed on insects for the first few days, but soon the diet is changed to regurgitated seeds. Two or three broods are often raised by a single pair, and young may sometimes be found in the nest as late as September. 

Countless Hazards

In ideal condition, the two or three broods raised by a single pair of greenfinches could be expected to produce a total of about 20 birds where there had been only two at the beginning. Nature is not infact so profligate, for although a highly successful pair may be able to produce three large broods, the great majority of breeding attempts actually fail. Failure arises in many ways lack of food may cause starvation, one of the adults may die or be killed or a predator may find the nest and eat the eggs or young. Apart from these dangers, the eggs might be infertile the nest may be blown out of its bush or the bush may be destroyed during agricultural or gardening work. In any case the production of eggs and the successful fledging of young is not the end of the parent’s responsibility, for they also have to look after the young birds, out of the nest, for a period of ten days or more, while they learn about the world and how to find food for themselves. 

Resilient Population
 
Besides all the difficulties that they have to face a breeding time, greenfinches are affected by wide variations in winter weather condition from year to year. Despite this the British breeding population as shown by the Common Birds Census farmland index, has remained constant over the last 25 years. The two cold winters in 1961-62 and 1962-63 probably halved the population, but it had returned to an average level by 1966. Since then it has varied by less than 10% either way, except in 1975 when it was rather than normal. These figures are based on observation made on farmland perhaps the habitat holding the most stable populations. The figures relating to woodland are based on a smaller sample and show a rather greater fluctuation. 

The prospect for this attractive bird looks excellent, with range expansions being reported during the present century. These have occurred in western areas, where the birds were formerly absent and also in city center areas. The most serious problem which they are likely to face arises from the increasing use of herbicides in cereal growing and other farming. IF the trend continues the range of species of weeds which are able to seed and thus produce natural winter feeding for the birds may be reduced. On current evidence, it seems likely that human bird lovers will more than make up for the deficiency, with the plentiful supplies of seeds and peanuts that they put out for the birds in their gardens.

Italian designer reveals plans for spectacular 164ft super-yacht made out of BRONZE

Italian super-yacht designer Federico Fiorentino has revealed a beautiful new concept that could one day be a floating playground for a billionaire’s. Well, the most luxurious vessel, called “The Belafonte”, is a super-yacht on steroids with a substantial bow and remarkable bronze exterior that catches the sun’s reflection off the sea.

At 164ft in length, the aluminum yacht takes full advantage of its outdoor space, boasting three decks with number of room for lounging or partying. With room for up to ten overnight guests, the mini-cruise ship has five lavish cabins, including a large VIP suite, two twin cabins and a double cabin.

The owner will retire to the largest room of all. At nearly 900 square feet, it has a lovely separate studio, balcony, walk-in closets and two modern bathrooms. Visitors will be pampered by the ship’s crew as they can relax in a saloon, outdoor dining area, pool or a shaded sky lounge. Renderings of the striking super-yacht show a hot tub surrounded by sun loungers on the top deck, while the airy middle deck boasts a small pool just steps from a large, circular table for alfresco dining. So the front of the upper deck features a private lounge for sunbathing. According to the Super-yacht Times, the vessel has a top speed between 20 to 27mph. (18 and 24 knots), and the Milan-based designer has already garnered interest from a potential buyer.

Wild Adventure of a Man and his Dog in Breathtaking Nature Photographs



Well, few things in the animal kingdom are very stronger than the bond between people and dogs, and it is the modest but powerful force behind this relationship that gives illustrator John Stortz’s photos their charm. When he travels throughout the United States with his attractive and fittingly named dog Wolf, he takes photographs of some of the stunning locations they’ve visited. Without any doubt these’re great adventures, excellent shooting, and most magnificent travelling companion a man can have.

The faithful dog, whose full name is “Wolfgang” teamed up with Stortz when he adopted Wolf from a shelter about two years ago, their Instagram is really a desire to browse, as the photographs of the lovely wolf-like Wolfgang are punctuated by Stortz’s striking illustrations. However Stortz draws a diversity of subjects, his affection for nature and the Inspiration of Wolf on his work is clear. Be sure to take a lovely look! The added dimension of the relationship between photographer and dog makes the difference between sighted and reading the photographs.

The Majestic Beauty of Earth From Above



Our planet earth is extremely beautiful, that has captured by British Photographer Peter Adams with stunning images of African deserts, plunging waterfalls and Arctic snows capes from 3,000ft, is making some of the world’s greatest landscapes look like captivating works of abstract art. The nature lover photographer travelled thousands of miles to document the varied surfaces of the planet (all from high above). The 55-year-old, from the Cotswolds, snapped the images while flying in light aircraft, helicopters and gyrocopters over some of the most well-known tourist destinations in the world, including Yellowstone National Park in the US and Namibia’s Namib Desert.

From high above, Yellowstone’s Grand Prismatic Spring looks like an alien volcano, while the desert in Andalucia, Spain looks like a scene from Mars. Some of his most remarkable photographs were captured in Australia, where he flew over the blue waters at the Great Barrier Reef and a beach in Queensland, where the sand meets the sea to create an outstanding swirling pattern. Moreover another image from Queensland shows the destructive force of lightning, as a green forest is marred by a patch of grey, dead trees. In other scenes, travelers look like ants as they snap photos of a superb waterfall in Iceland, and strips of land nestled between canals in northern Holland look like brushstrokes. Peter’s work has been featured in publications around the world and he has been recognized with several awards and honors, including 2003 Travel Photographer of the Year.

A New Bird “Cryptic Treehunter” Discovered in Brazil



Brazilian ornithologists Dr. Juan Mazar Barnett & Dr. Dante Buzzetti of the Center for Ornithological Studies in São Paulo have discovered a new species of bird that likes to lives in the dense, humid forests of northeastern Brazil. The bird named is “Cryptic treehunter” (Cichlocolaptes mazarbarnetti), is a member of the South American bird family Furnariidae (ovenbirds). According to the team, the Cryptic treehunter is one of the rarest birds in the world. The lovely bird is about 22 cm long, with the tail more than one-third of the length and weight is about 48 g. The bird crown and forehead are jet-black, and back of the neck, the back, and the rump are cinnamon-brown, however the tail is pale orange-rufous, with the central rectrices darker dorsally. The throat, sides of the head, supercilium and supraloral-stripe are pinkish-buff, while lower throat and the sides of neck are cinnamon-brown. The breast, belly, and underwing coverts are cinnamon. The Cryptic treehunter is described from a specimen that for many years had been confused with another species, the Alagoas foliage-gleaner (Philydor novaesi).

“The new species differs from the Alagoas foliage-gleaner by its considerably larger size, heavier body-mass, darker and more uniform forehead and crown, absence of buffy periocular-feathers, and a pale orange-rufous tail that contrasts with the rump and the rest of the dorsal plumage. The bird has a flat-crowned appearance and a larger, deeper-based, and generally stouter bill,” and the new species belongs in the genus “Cichlocolaptes”. The BirdLife International Brazil Programme says we expected that a maximum of 5 to 10 pairs may have existed in the entire reserve in 2004; though, the number of birds remaining is likely lower. At Frei Caneca, we guess that no more than one or two pairs survive. We’re proposing that this species should be categorized as Critically Endangered at a national and global level, and we ponder the situation of its conservation to be dangerous in that it’ll entail urgent action to avoid its global extinction.
