Numbered Trumpeter Swan

Volunteers Report Trumpeter Swan Wing Tags – Revealing a Self-Sustaining Population in Ontario

A team of vigilant observers has helped biologist and TTSS board member Harry Lumsden to track and tally what is now a successful, self-sustaining population of Trumpeter Swans in Ontario.  Ontario’s Trumpeters are marked with yellow wing tags. In a typical year, observers report 300-360 individuals. Once a number is read and reported, the data can be entered to help track that bird’s movements, habitat use and reproductive success. Data from tagged bird sightings allows biologists to produce a genetic family tree and to record population growth and range extension. This past year 116 birds were marked in Ontario — 70 of them caught by hand by the team of Bev and Ray Kingdon, Julie Kee and Kyna Intini in the wintering flock that feeds at La Salle Park and other areas near Burlington on the west end of Lake Ontario. Peak numbers recorded for this wintering group were 160 Trumpeters along with 100 Mute Swans. Smaller congregations, where other birds were marked, included Bluffer’s Park, Frenchman’s Bay, Whitby Harbour and Wye Marsh.

Tag sightings by observers across the southern part of the province proved useful even when the number was not recorded. Ontario observers have been asked to keep track of the proportion of marked to unmarked birds in groups observed (even if number is not read). The last four year’s analysis of reported proportions reveals a steady increase in the wild population. As the population grows, the percent of total marked birds has declined. In 2005, it was 54%. By 2006 it had declined to 46%, 2007, 44% and in 2008, 39%. In 2007-08 364 tagged birds were reported. By using this calculated annual percentage rate, with an adjustment for marked birds missed (based on year to year variance in reports of known live tagged birds) along with the percentage ratio of marked to unmarked birds, biologists estimate the population.

Doing the numbers, Harry Lumsden recorded quadruple figures for the Sept. 2007 to Aug. 2008 report — a total of 1018 birds.  The milestone of 1000 birds had been passed!  This number is for adult and sub-adult birds. Cygnets of the year averaged 39% for this period. Applying this ratio to overall numbers, Ontario’s breeding population estimate registers a remarkable 1415 birds. When Harry Lumsden started Ontario’s Trumpeter Swan Restoration program in 1982, Trumpeters had not been seen for almost 100 years, since 1886 when a hunter at Lake Erie’s Long Point shot the last known individual. The Ontario Field Ornithologists honored Lumsden with their Distinguished Ornithologist award for 2008. Among his many career achievements, leading the successful restoration of Ontario’s Trumpeter Swans must bring great satisfaction.

Mute Swans There Role in Culture

Role in culture

Mute swans "Cob" and "Pen"

Many of the cultural aspects refer to the Mute Swan of Europe. Perhaps the best known story about a swan is The Ugly Duckling fable. The story centres around a duckling who is mistreated until it becomes evident he is a swan and is accepted into the habitat. He was mistreated because real ducklings are, according to many, more attractive than a cygnet, yet cygnets become swans, which are very attractive creatures. Swans are often a symbol of love or fidelity because of their long-lasting monogamous relationships. See the famous swan-related operas “Lohengrin” and “Parsifal”. In the Irish legend “The Wooing of Etain”, the king of the Sidhe (subterranean-dwelling, supernatural beings) transforms himself and the most beautiful woman in Ireland, Etain, into swans to escape from the king of Ireland and Ireland’s armies.

Swans feature strongly in mythology. In Greek mythology, the story of Leda and the Swan recounts that Helen of Troy was conceived in a union of Zeus disguised as a swan and Leda, Queen of Sparta. Other references in classical literature include the belief that upon death the otherwise silent Mute Swan would sing beautifully – hence the phrase swan song; as well as Juvenal’s sarcastic reference to a good woman being a “rare bird, as rare on earth as a black swan,” from which we get the Latin phrase “rara avis,” rare bird.

The Irish legend of the Children of Lir is about a stepmother transforming her children into swans for 900 years. The swan has recently been depicted on an Irish commemorative coin.

In Norse mythology, there are two swans that drink from the sacred Well of Urd in the realm of Asgard, home of the gods. According to the Prose Edda, the water of this well is so pure and holy that all things that touch it turn white, including this original pair of swans and all others descended from them. The poem “Volundarkvida”, or the “Lay of Volund”, part of the Poetic Edda, also features swan maidens.

In the Finnish epic Kalevala, a swan lives in the Tuoni river located in Tuonela, the underworld realm of the dead. According to the story, whoever killed a swan would perish as well. Jean Sibelius composed the “Lemminkäinen Suite” based on Kalevala, with the second piece entitled “Swan of Tuonela” “(Tuonelan joutsen)”. Today, five flying swans are the symbol of the Nordic Countries and the whooper swan (“Cygnus cygnus”) is the national bird of Finland.

In Latin American literature, the Nicaraguan poet Ruben Darío (1867-1916) consecrated the swan as a symbol of artistic inspiration by drawing attention to the constancy of swan imagery in Western culture, beginning with the rape of Leda and ending with Wagner’s “Lohengrin”. Darío’s most famous poem in this regard is “Blasón – “Coat of Arms” (1896), and his use of the swan made it a symbol for the Modernismo poetic movement that dominated Spanish language poetry from the 1880s until the First World War. Such was the dominance of Modernismo in Spanish language poetry that the Mexican poet Enrique González Martínez attempted to announce the end of Modernismo with a sonnet provocatively entitled, “Tuércele el cuello al cisne – “Wring the Swan’s Neck” (1910).

Swans are revered in many religions and cultures, especially Hinduism. The Sanskrit word for swan is “hamsa” or “hansa”, and it is the vehicle of many deities like the goddess Saraswati. It is mentioned several times in the Vedic literature, and persons who have attained great spiritual capabilities are sometimes called Paramahamsa (“Great Swan”) on account of their spiritual grace and ability to travel between various spiritual worlds. In the Vedas, swans are said to reside in the summer on Lake Manasarovar and migrate to Indian lakes for the winter, eat pearls, and separate milk from water in a mixture of both. Hindu iconography typically shows the Mute Swan. It is wrongly supposed by many historians that the word “hamsa” only refers to a goose, since today swans are no longer found in India, not even in most zoos. However, ornithological checklists clearly classify several species of swans as vagrant birds in India.

Reflections of Love

The ballet “Swan Lake” by Pyotr Tchaikovsky is considered among both the most important works of this composer and among the often-performed classics of ballet. It is partially based on an ancient German legend, which tells the story of Odette, a princess turned into a swan by an evil sorcerer’s curse – to which were added similar elements from Russian Russian folk tales [ such as The White Duck collected by Alexander Nikolayevich Afanasyev in Narodnye russkie skazki ] . Some major elements (girls turned to swans and living in a lake, and a hero falling in love with one of them) are also shared by the Irish Mythology story of Caer Ibormeith.
