The Event

As part of Global Goals Week, the Skoll Foundation and the United Nations Foundation are pleased to present We the Future: Accelerating Sustainable Development Solutions on September 21, 2017 at TED Theater in New York.
The Sustainable Development Goals, created in partnership with individuals around the world and adopted by world leaders at the United Nations, present a bold vision for the future: a world without poverty or hunger, in which all people have access to healthcare, education and economic opportunity, and where thriving ecosystems are protected. The 17 goals are integrated and interdependent, spanning economic, social, and environmental imperatives.
Incremental change will not manifest this new world by 2030. Such a shift requires deep, systemic change. As global leaders gather for the 72nd Session of the UN General Assembly in September, this is the moment to come together to share models that are transforming the way we approach the goals and equipping local and global leaders across sectors to accelerate achievement of the SDGs.




Together with innovators from around the globe, we will showcase and discuss bold models of systemic change that have been proven and applied on a local, regional, and global scale. A curated audience of social entrepreneurs, corporate pioneers, government innovators, artistic geniuses, and others will explore how we can learn from, strengthen, and scale the approaches that are working to create a world of sustainable peace and prosperity.

They can be distinguished from choughs by their uniformly grey underwings and their black beaks and legs. It is mandatory to procure user consent prior to running these cookies on your website. Earthworms are not usually extracted from the ground by western jackdaws but are eaten from freshly ploughed soil. Measuring 34–39 centimetres (13–15 in) in length, the western jackdaw is a black-plumaged bird with a grey nape and distinctive pale-grey irises. [8] This onomatopoeic name, based on the western jackdaw's call, now refers to corvids of the genus Pyrrhocorax; the red-billed chough (Pyrrhocorax pyrrhocorax), formerly particularly common in Cornwall, became known initially as the "Cornish chough" and then just the "chough", the name transferring from one species to the other.[9]. [63], In his book King Solomon's Ring, Konrad Lorenz described and analysed the complex social interactions in a western jackdaw flock that lived around his house in Altenberg, Austria. [32][33] Most of the plumage is a shiny black, with a purple (in subspecies monedula and spermologus) or blue (in subspecies cirtensis and soemmerringii) sheen on the crown,[34] forehead, and secondaries, and a green-blue sheen on the throat, primaries, and tail. The 12th-century historian William of Malmesbury records the story of a woman who, upon hearing a jackdaw chattering "more loudly than usual," grew pale and became fearful of suffering a "dreadful calamity", and that "while yet speaking, the messenger of her misfortunes arrived". [84] The diet averages 84% plant material except when breeding, when the main food source is insects. This female immediately assumed a dominant position in the social hierarchy and demonstrated this by pecking others. [7] The metallic chyak call may be the origin of the jack part of the common name,[11] but this is not supported by the Oxford English Dictionary. In this display, a bird lowers its bill and erects its nape and head feathers, and sometimes slightly lifts its wings. The Veneti are fabled to have bribed the jackdaws to spare their crops. They are social birds and will often be found with rooks and crows. [108], The jackdaw is featured on the Ukrainian town of Halych's ancient coat of arms, the town's name allegedly being derived from the East Slavic word for the bird. [72] The eggs are a lighter colour than those of other corvids,[73] being smooth, a glossy pale blue or blue-green with darker speckles ranging from dark brown to olive or grey-violet. The chicks are fed by both parents and fledge at 28-32 days. Found across Europe, western Asia and North Africa; it is mostly resident, although northern and eastern populations migrate south in the winter. [43] Occasionally, a sick or injured western jackdaw is mobbed until it is killed. [65] In the defensive-threat posture, the bird lowers its head and bill, spreads its tail and ruffles its feathers. [37] Wind tunnel experiments show that the preferred gliding speed is between 6 and 11 metres (20 and 36 ft) per second and that the wingspan decreases as the bird flies faster. They fledge after 28–35 days,[72] and the parents continue to feed them for another four weeks or so. The cause of the increase is unknown, but a reduction in the number of rooks may have benefited the species locally, or rooks overwintering in Belarus may have caused western jackdaws to relocate to Warsaw. [103] The mythical Princess Arne Sithonis was bribed with gold by King Minos of Crete, and was punished by the gods for her greed by being transformed into an equally avaricious jackdaw, who still seeks shiny things. [105] Pliny notes how the Thessalians, Illyrians, and Lemnians cherished jackdaws for destroying grasshoppers' eggs. [70] They can take over old nest sites of the black woodpecker (Dryocopus martius)[71] and stock dove (Columba oenas). An authorised person must comply with the requirements of the Wildlife and Countryside Act 1981 and does not need to show that the birds were a nuisance before trapping them. [26] Habitats with a mix of large trees, buildings, and open ground are preferred; open fields are left to the rook, and more wooded areas to the Eurasian jay (Garrulus glandarius). [37] Along with other corvids such as the rook, common raven (Corvus corax), and hooded crow (C. cornix), some western jackdaws spend the winter in urban parks; populations measured in three urban parks in Warsaw show increases from October to December, possibly due to western jackdaws migrating there from areas further north. [48] Their range expands northwards into Russia to Siberia during summer and retracts in winter. [26] Landfill sites, bins, streets, and gardens are also visited, more often early in the morning when there are fewer people about. He ringed them for identification and caged them in the winter to prevent their annual migration. The species was hunted for its threat to grain crops and for propensity for nesting in belfries until the mid-20th century. Upon pairing, the female assumes the same social position as her partner. jack snipe), and the archaic native English word daw. The common name jackdaw first appeared in the 16th century, and is thought to be a compound of the forename Jack, used in animal names to signify a small form (e.g. [2] Owing to its supposed fondness for picking up coins, Linnaeus gave it the binomial name Corvus monedula, choosing the specific name mǒnēdŭla, which is derived from moneta, the Latin stem of the word "money". [23] The names Coloeus monedula and Coloeus dauuricus have since been adopted by the International Ornithological Congress in their official list. The jackdaw has a blue-black colour on the top of its head, its back is black, it is dark grey underneath and the wings and tail are glistening black. [26] However, it is regionally extinct in Malta and Tunisia. [106] Czech superstition formerly held that if jackdaws are seen quarreling, war will follow, and that jackdaws will not build nests at Sázava after being banished by Saint Procopius. [13] This is a contact or greeting call. [61] Widowed or separated birds fare badly, often being ousted from nests or territories and unable to rear broods alone.[61]. Western jackdaws usually breed in colonies with pairs collaborating to find a nest site, which they then defend from other pairs and predators during most of the year. They thrive when forested areas are cleared and converted to fields and open areas. [40] A study in southern Spain examining western jackdaw pellets found that they contained significant amounts of silicaceous and calcareous grit to aid digestion of vegetable food and supply dietary calcium. A mated pair usually constructs a nest by improving a crevice by dropping sticks into it; it is then built on top of the platform formed. It was also frequently known quasi-nominally as Jack. "BirdLife International (2012) Species factsheet: "Long-term Spatio-temporal Dynamics of Corvids Wintering in Urban Parks of Warsaw, Poland", "Long-term Population Trends of Corvids Wintering in Urban Parks in Central Poland", "Cooperative Hunting of Jackdaws by the Lanner Falcon (, "Cognitive Adaptations of Social Bonding in Birds", Philosophical Transactions of the Royal Society B, "Within-clutch Repeatability of Egg Dimensions in the Jackdaw, "Functional Morphology and Integration of Corvid Skulls – a 3D Geometric Morphometric Approach", "Grit Ingestion and Cereal Consumption in Five Corvid Species". [80] Examination of the gizzards of western jackdaws shot in Cyprus in spring and summer revealed a diet of cereals (predominantly wheat) and insects (notably cicadas and beetles). [41] Nestlings begin making a soft cheep at about a week of age. Western jackdaws show much higher levels of active giving than has been documented for other species, including chimpanzees. [13] They are vagrants to the Faroe Islands, particularly in the winter and spring, and occasionally to Iceland. [74] Egg size and weight varies slightly between subspecies; those of subspecies monedula average 35.0 by 24.7 millimetres (1.38 in × 0.97 in) and 11.1 g (0.39 oz) in weight, those of subspecies soemmerringii 34.8 by 25.0 millimetres (1.37 in × 0.98 in) in size and 11.3 g (0.40 oz) in weight, and those of subspecies spermologus 35.0 by 25.2 millimetres (1.38 in × 0.99 in) in size and 11.5 g (0.41 oz) in weight. The other pest species that can be controlled by trapping are the crow, jay, magpie and rook. [53] The same data from Warsaw, collected from 1977 to 2003, showed that the wintering western jackdaw population had increased four-fold. [66], Western jackdaws entreat their partners to preen them by showing their nape and ruffling their head feathers. "Density and Age of Breeding Pairs Influence Feral Pigeon, "Nest Occupation and Prey Grabbing by Saker Falcon (, Ethological Conference, Budapest, Hungary, 2005, "Characterization of Two Novel Polyomaviruses of Birds by Using Multiply Primed Rolling-Circle Amplification of Their Genomes", (PDF; 2.1 MB) Ageing and sexing by Javier Blasco-Zumeta & Gerd-Michael Heinze, Feathers of Eurasian jackdaw (Corvus monedula), https://en.wikipedia.org/w/index.php?title=Western_jackdaw&oldid=988747155, Short description is different from Wikidata, Creative Commons Attribution-ShareAlike License, This page was last edited on 15 November 2020, at 00:49. [18], A study in 2000 found that the genetic distance between western jackdaws and the other members of Corvus was greater than that within the rest of the genus. The Jackdaw is a much smaller bird than the Carrion Crow or Rook. [55] Western jackdaws frequently congregate with hooded crows[35] or rooks,[37] the latter particularly when migrating or roosting. [26] C. m. monedula intergrades into C. m. soemmerringii in a transition zone running from Finland south across the Baltic and eastern Poland to Romania and Croatia. [36], Immature birds have duller and less demarcated plumage. [80]), Diptera, and Lepidoptera species, as well as snails and spiders. [74], The great spotted cuckoo (Clamator glandarius) has been recorded as a brood parasite of the western jackdaw, depositing its eggs in their nests in Spain and Israel. Adults are readily distinguished, since the Daurian has a pied plumage, but immature birds are much more similar, both species having dark plumage and dark eyes. [27], Measuring 34–39 centimetres (13–15 in) in length and weighing around 240 grams (8.5 oz), the western jackdaw is the second smallest member of the genus Corvus. Adult Male and Female. [43] The European jackdaw can be trained to imitate human speech. This website uses cookies to improve your experience. It was recommended that steps be taken to prevent birds from pecking open bottles in the future. [61], Western jackdaws hatch asynchronously and incubation begins before clutch completion, which often leads to the death of the last-hatched young. [52] They have also occurred as vagrants in Gibraltar, Mauritania, and Saint Pierre and Miquelon,[1] and one is reported to have been seen in Egypt. This act was taken up in a piecemeal fashion, but Elizabeth I passed the Act for the Preservation of Grayne in 1566 that was taken up with more vigour. [64], Social hierarchy in western jackdaw flocks is determined by supplanting, fighting, and threat displays—several of which have been described. [92], Western jackdaws have learned to peck open the foil caps of milk bottles left on the doorsteps after delivery by the milkman. From a distance, it can be confused with a rook (Corvus frugilegus), or when in flight, with a pigeon or chough. It contains two relatively small species both named "jackdaws". Males and females look the same.

A bill-down posture is another commonly used agonistic behaviour. Western jackdaws undergo a complete moult from June to September in the western parts of their range, and a month later in the east. This activity was linked to cases of Campylobacter gastroenteritis in Gateshead in northeast England[93] and led the Department of Health to suggest that milk from bottles which had been pecked open should be discarded. Jackdaws are small blue-black crows. The function of this behaviour is not fully understood, though it has been found to be detached from nutrition and compatible with hypotheses of mutualism, reciprocity and harassment avoidance. Flies around cow pats are caught by jumping from the ground or at times by dropping vertically from a few metres onto the cow pat. [86] They have been recorded taking eggs and nestlings from the nests of the skylark (Alauda arvensis),[87] Manx shearwater (Puffinus puffinus), razorbill (Alca torda), common murre (Uria aalge), grey heron (Ardea cinerea),[82] rock pigeon (Columba livia),[88] and Eurasian collared dove (Streptopelia decaocto). Western jackdaws are monogamous and build simple nests of sticks in cavities in trees, cliffs, or buildings. [3][4] Jackdaws are sometimes placed in the genus Coloeus, from the Ancient Greek κολοιός (koloios) for jackdaw,[5] though most subsequent works have retained the two jackdaw species in Corvus. The main call, frequently given in flight, is a metallic and squeaky chyak-chyak or kak-kak. Also eaten are small rodents, bats,[83] the eggs and chicks of birds, and carrion such as roadkill. [39] The western jackdaw is very similar in morphology, behaviour, and calls to the Daurian jackdaw, with which its range overlaps in western Asia. The legs are black, as is the short stout bill,[32] the length of which is about 75% of the length of the rest of the head. [47], Most populations are resident, but the northern and eastern populations are more migratory,[27] relocating to wintering areas between September and November and returning between February and early May. [94], An outbreak of a gastrointestinal illness in Spain which was causing mortalities in humans has been linked to western jackdaws. [12] Daw, first used for the bird in the 15th century, is held by the Oxford English Dictionary to be derived from the postulated Old English dawe, citing the cognates in Old High German tāha, Middle High German tāhe or tāchele, and modern German Dahle or Dohle, and dialectal Tach, Dähi, Däche and Dacha. He found that the birds have a linear hierarchical group structure, with higher-ranked individuals dominating lower-ranked birds, and pair-bonded birds sharing the same rank. However, individual variation, particularly in juveniles and also during the months before moulting, can often be greater than geographic differences. [76] Replacement clutches are very rarely laid in the event of clutch failure. [26] Various feeding methods are employed, such as jumping, pecking, clod-turning and scattering, probing the soil, and occasionally, digging. Juvenile jackdaws have a brownish tinged body and the head lacks the blue gloss. [42] From day 25, the young cease calling and become silent if they hear an unfamiliar noise. Unmated females are the lowest members in the pecking order, and are the last to have access to food and shelter. [13][14][15][16], An archaic collective noun for a group of jackdaws is a "clattering". But opting out of some of these cookies may have an effect on your browsing experience. They also have shorter, thicker necks, much shorter bills and frequently fly in tighter flocks. [85], Opportunistic and highly adaptable, the western jackdaw varies its diet markedly depending on available food sources. By using our site you consent to the use of cookies. [64] Young males establish their individual status before pairing with females. Four subspecies are recognised, which differ mainly in the colouration of the plumage on the head and nape. They feed with their heads held down or horizontally. [89] The saker falcon (Falco cherrug) has been reported stealing food from western jackdaws on powerlines in Vojvodina in Serbia. It has also been proposed that food sharing may be motivated by prestige enhancement. [18] The species has been recorded outcompeting the tawny owl (Strix aluco) for nest sites in the Netherlands. An omnivorous and opportunistic feeder, it eats a wide variety of plant material and invertebrates, as well as food waste from urban areas. Genetic analysis of pairs and offspring shows no evidence of extra-pair copulation[60] and there is little evidence for couple separation even after multiple instances of reproductive failure. [37] They may also use church steeples for nesting, a fact reported in verse by 18th century English poet William Cowper: A great frequenter of the church, Supplanting is where one bird moves in and displaces another from a perch-site. [66], Western jackdaws become sexually mature in their second year. Out of these cookies, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. [37] Elsewhere, western jackdaws congregate over winter in the Ural Valley in northwestern Kazakhstan, the northern Caspian, and the Tian Shan region of western China. legs and feet are black and their eyes are light grey. They have a black forecrown with a blue-gloss, and the hindcrown, nape and sides of the head are pale grey. The Daurian tends to be darker, with a less contrasting nape than the Western. Like its relatives, jackdaws are intelligent birds, and have been observed using tools. Flock sizes increase in autumn and large flocks group together at dusk for communal roosting.They become sexually mature in the first breeding season, and there is little evidence for divorce or extra pair coupling, even after multiple instances of reproductive failure. [34] The irises of adults are greyish or silvery white while those of juveniles are light blue, becoming brownish before whitening at around one year of age. [6], The original Old English word ċēo (pronounced with initial ch) gave modern English "chough"; Chaucer sometimes used this word to refer to the western jackdaw,[7] as did Shakespeare in Hamlet although there has been debate about which species he was referring to. Where, bishoplike, he finds a perch, Nest platforms can attain a great size. [66] Breeding colonies may also edge out those of the red-billed chough, but in turn be ousted by larger corvids such as the carrion crow, rook or magpie. This extreme is seen when facing off over nests or females. [67] They nest in cavities in trees or cliffs, in ruined or occupied buildings and in chimneys, the common feature being a sheltered site for the nest. It has characteristic jerky wing beats when flying, though these are not evident when birds are migrating. [37] The head is a sooty black, sometimes with a faint greenish sheen and brown feather bases visible; the back and side of the neck are dark grey and the underparts greyish or sooty black. [105] A jackdaw standing on the vanes of a cathedral tower is said to foretell rain. Jackdaws are highly gregarious and are generally seen in small to large flocks, though males and females pair-bond for life and pairs stay together within flocks. Western jackdaws also have a hoarse, drawn-out alarm call,[13] arrrrr or kaaaarr, used when warning of predators or when mobbing them. Jackdaws eat a varied diet including Invertebrates, fruit and seeds. Birds mainly preen each other's head and neck. Their eyes are dark brown until the end of the first winter and they reach sexual maturity at two years. [109] In The Book of Laughter and Forgetting (1979), Milan Kundera notes that Franz Kafka's father Hermann had a sign in front of his shop with a jackdaw painted next to his name, since "kavka" means jackdaw in Czech. [45] Censuses of bird populations in marginal uplands in Great Britain show that western jackdaws greatly increased in numbers between the 1970s and 2010, although this increase may be related to recovery from previous periods when they were regarded as pests. [50] The subspecies soemmerringii occurs in south-central Siberia and extreme northwestern China and is accidental to Hokkaido, Japan. She lays four to five eggs which are a pale blue colour and speckled with brownish black spots. They will also eat carrion and other birds’ eggs and nestlings. https://www.birdspot.co.uk/wp-content/uploads/2019/10/jackdaw.mp3. Corvus monedula. The young bird has a brown iris which turns blue as it becomes an adult. [36] Western jackdaws undergo a complete moult from June to September in the western parts of their range, and a month later in the east. [34] There are rictal bristles covering around 40% of the maxilla and 25% of the lower mandible. [103], In some cultures, a jackdaw on the roof is said to predict a new arrival; alternatively, a jackdaw settling on the roof of a house or flying down a chimney is an omen of death, and coming across one is considered a bad omen. It is gregarious and vocal, living in small groups with a complex social structure in farmland, open woodland, on coastal cliffs, and in urban settings. Vegetable items consumed include farm grains (barley, wheat and oats), weed seeds, elderberries, acorns, and various cultivated fruits. After this, the voice deepens and softens. The western jackdaw was one of the many species originally described by Carl Linnaeus in his 18th century work Systema Naturae. [99] Permission to shoot western jackdaws in spring and summer exists in Cyprus as they are thought (incorrectly) to prey on gamebirds. Their eyes are dark brown until the end of the first winter and they reach sexual maturity at two years. "[59], Highly gregarious, western jackdaws are generally seen in flocks of varying sizes, though males and females pair-bond for life and pairs stay together within flocks. Populations in central Asia have slightly larger wings and western populations have a slightly heavier bill. [51] A small number of western jackdaws reached northeastern North America in the 1980s and have been found from Atlantic Canada to Pennsylvania. [34], A skilled flyer, the western jackdaw can manoeuvre tightly as well as tumble and glide. [19] This led Pamela Rasmussen to reinstate the genus name Coloeus, created by Johann Kaup in 1829,[20] in her Birds of South Asia (2005),[21] a treatment also used in a 1982 systematic list in German by Hans Edmund Wolters. [37] Flying western jackdaws are distinguishable from other corvids by their smaller size, faster and deeper wingbeats and proportionately narrower and less fingered wing tips. They make their nests from twigs lined with rags, soil, bark and hair.Jackdaws lay 4-6 pale blue eggs with blackish-brown speckles. The main differences are the presence or absence of a whitish partial collar at the base of the nape, the variations in the shade of the nape and the tone of the underparts. To the east, it occurs throughout Turkey, the Caucasus, Iran, Iraq, Afghanistan, Pakistan, and northwestern India. You also have the option to opt-out of these cookies. [24] The two species of jackdaw have been reported to hybridise in the Altai Mountains, southern Siberia, and Mongolia. [79] The European pine marten (Martes martes) raids isolated nests in Sweden but is less successful when nests are part of a colony.
