The Kirtland's warbler is an endangered bird that nearly went extinct. Constantly pumps tail up and down. These birds winter only in the Bahamas and the Turks and Caicos Islands. This private-public partnership represents a new model for addressing the ongoing needs of a delisted, conservation-reliant bird species. This early successional habitat was historically created by wildfire, but fire suppression programs almost eliminated the habitat and the species itself. In 1971 the third decennial census counted 201 singing males, whereas the 1961 census had found 501 breeding pairs, showing a 60% decrease in population over the 1960s. Almost the entire population breeds in north and central Michigan, with small (but increasing) numbers in Minnesota, Wisconsin, and Canada. Scientific Name: Dendroica kirtlandii. A rare bird of the Michigan jack pine forests, the Kirtland's Warbler is dependant upon fire to provide the small trees and open areas that meet its rigid habitat requirements for nesting. [2] This same year the migration route was first detailed in a paper by Charles C. Adams. The plan entailed the management of state and federal land through clear cutting, controlled burning and planting jack pine to expand suitable nesting habitat for Kirtland's warbler, as well as having the government acquire more land for this purpose. Poorly sited wind turbines are a growing hazard to the Kirtland's Warbler, especially those around the species' fall migration route in the Great Lakes region. Keeping the Kirtland's Warbler population on the road to recovery will require continuing programs to create young Jack Pine forests and reduce nest parasitism by Brown-headed Cowbirds. Although only 167 singing male warblers were recorded in 1974, nevertheless the large number of fledglings meant the traps were effective. Development and fragmentation of forests in the eastern United States have allowed brown-headed cowbirds to greatly expand their range eastward. They lay 4-5 eggs at a time, which the female incubates for fourteen days, and the young usually stay with their parents for 9-10, once hatched. Sykes and Clench (1998) on the other hand, basing their analysis on 96 unambiguous records of both collected specimens and observations on thirteen different islands, as well as almost 451 observations over three months of the same two banded individuals on Eleuthera, found themselves unable to agree with this, finding that by far most records were from regrown coppice after abandonment of agricultural fields. In 1881 another massive conflagration burned down the forests in The Thumb. [citation needed] Eggs are laid in May to June. Including chicks, he returned to the city with fifteen birds, the greatest bounty ever collected in the USA. The cowbird traps were 4 by 4ft. (1997) also believed that the warbler inhabits shrubs, but they concluded that the species is entirely dependent on pineyards, stating that before the advent of deforestation of the high coppice after the colonisation of The Bahamas by pre-colonial Lucayan peoples, the bird must have been restricted to the northwestern islands which harbour these pineyards and absent from central, eastern and southern islands such as Eleuthera. [1] Some Michigan locals have questioned the cost and point of the program. Breeds only in young jack pine forests in northern Michigan and Wisconsin. There are a few scattered sprinkles in various shades of brown[2] and pink, these sprinkles and blotches concentrated at the top[3] or form a sort of wreath at the larger end. [5][6] The collection is attributed to Samuel Cabot Jr. himself,[6] a Boston merchant who had grown wealthy marketing imported Chinese goods, but the collector is more likely to be his son, the ornithologist Samuel Cabot III who was travelling through the region from Boston to the Yucatán at this time. In the 1990s this was garnered from a carbon sequestration fund, but that source of financing has been terminated. [29], In the 1920s the recognised expert on this species was a Chicago teenager named Nathan F. Leopold -an exceptionally intelligent and extremely wealthy young man who soon became more infamous as a child-murderer with a vainglorious belief in his status as Übermensch in the vein of Friedrich Nietzsche. The Kirtland's Warbler is the most endangered warbler in North America. Other warblers. As stated in the Recovery Plan, fire [4] The birds winter in The Bahamas and nearby Turks and Caicos Islands, where they are found on all islands investigated. (1998) published a repudiation of Sykes and Clench based on 101 warbler records, wherein they claimed the warblers do not prefer scrub coppice and reiterated their earlier assertion that the primary habitat of the birds was pineyards. The cheeks are black and the eye ring is white. The breeding range in Michigan and the wintering range in the Bahamas were discovered in the 1870s, but relatively few birds were seen in either place. Goal: To have a self-sustaining Kirtland’s warbler population throughout its known range at a minimum level of 1,000 pairs. Black-throated blue warbler. To that end, in December 2019, ABC and Black Swamp Bird Observatory filed suit in federal court, asserting that the agencies involved failed to comply with environmental laws during their evaluation of Icebreaker's impacts. However, in a January 2002 letter to the Region 3 Director, the Kirtland’s Warbler Recovery Team defined the term “self-sustaining” as a population free from intensive management. This period was most probably the heyday of the warbler. The other components were to limit public access land during nesting season, to conduct annual censuses of the warbler population, and lastly to intensively control the cowbird population. [28] As of 2016, the cowbird traps still capture 4,000 cowbirds a season. [28], Today the habitat of Kirtland's warbler is no longer being preserved by prescribed burns as these have proved too difficult to control (a forest service employee named James Swiderski was immolated during one of these burns in 1980),[4][37] and the species is entirely dependent on staggered harvests by the timber industry for its survival. One was that the age of the jack pines in a stand is the most pertinent determinant in the suitability of a particular terrain as a breeding habitat for the species, and another discovery was that the population was subject to a deleterious brood parasitism by the brown-headed cowbird. [6][29] Maynard was a prolific collector, securing in this and subsequent years another ten on the same island almost a dozen on Eleuthera, and a further two on Cat Island, but many other collectors were able to obtain quite a number of specimens in The Bahamas during these decades. [34] In 1971 a recovery plan was developed. Kirtland's Warbler is removed from the Endangered Species List The news was made official on Oct. 8 at a ceremony in East Lansing: The Kirtland's Warbler is no longer an endangered species. [24][29], In 1871, fed by dry conditions, high winds and piles of logging slash, a massive forest fire swept through lower Michigan, with another great fire in The Thumb of the Lower Peninsula, and a further huge forest fire on the Wisconsin-Michigan border and yet another around Windsor, Ontario. "As on the summer nesting grounds [in the Great Lakes region], it selects dense, early-successional habitat," he says. Since Kirtland’s warblers will only nest in stands of young jack pines, the population dwindled dramatically before scientists realized that there is a role for fire in forest ecology — and in the Kirtland’s warbler life history. [15], For breeding habitat it requires large areas of young jack pine (Pinus banksiana) on sandy soil. [38] Beginning in 2005 a small number have been observed in Wisconsin. The birds spend the winter in the Bahamas and other islands of the West Indies. [15], If Haney et al. [15] Other common plants in this habitat are blueberry (Vaccinium angustifolium), sweet fern (Comptonia peregrina), Canada mayflower (Maianthemum canadense) and various grasses. Blue-gray above and lemon-yellow below with broken white eye-ring, thin white wingbars, and black spotting on sides. [12], Jack pine is a species of somewhat smallish pine[citation needed] with a distribution that spans almost across North America. [14] Its mating song is a loud chip-chip-chip-too-too-weet-weet often sung from the top of a snag (dead tree) or northern pin oak (Quercus ellipsoidalis) clump. Blackburnian warbler. 0:00 / Kirtland's warbler (song) song. The Kirtland’s warbler was already assessed as Endangered when the Endangered Species Act took effect in 2008. Baird attributed the collection to one Charles Pease in his 1852 description,[7] but by 1858 he had changed his story and was attributing it to Kirtland (see below). The population has increased five-fold since the early 1950s, far surpassing the recovery goal for the species. [34], The birds depend on The Bahamas and adjacent territories during winter; in 1998 their winter habitat was judged to be extremely widespread and it was calculated that there is enough area and habitat in the Bahamas to house a population of roughly more than 500,000 birds. Map courtesy of Birds of North America, https://birdsna.org, maintained by Cornell Lab of Ornithology. [3], Baird compared and found it most similar to Setophaga coronata, finding it best distinguishable by having a nearly uniformly yellow belly, no conspicuous yellow rump or crown, less black in the feathers of the crown, and a considerably larger and stouter bill and feet. [20] Red pine was interspersed with the jack pine because the latter is relatively worthless as lumber, and it was hoped this configuration would make the project more economically sustainable. This period also happens to be the time when the most Kirtland's warblers ever were taken, although in this period ornithologists were as yet unaware where it bred, and almost all these birds were taken in The Bahamas and Turks and Caicos or along the migration route. [6], A warbler occupies a breeding territory of 2.7 to 3.4ha depending on location, but a larger wintering territory of 6.9 to 8.3ha depending on the island. Kirtland’s Warblers were on the brink of extinction throughout the 1970’s and 80’s, when numbers were estimated to be as low as 200 males. It nests only in stands of young jack pines in central Michigan, a habitat that grows up only briefly after fires, and its nests have been heavily parasitized in recent decades by Brown-headed Cowbirds. "The Kirtland's Warbler". This created the conditions for the extensive woodlots of jack pine, a pioneer species, found today. That same year 216 singing male warblers were recorded an increase of 9.2% from the 200 males recorded in 1972, and the first increase recorded ever. The most destructive threat in the winter range are thought to be house cats, at least on some islands. Occurrence Ontario Status history Designated Endangered in April 1979. The Kirtland's Warbler breeds in areas of Michigan, Wisconsin and Ontario. [15] They, as well as Mayfield, state many of the earlier records used by Lee et al. Average clutch size in the region almost doubled. In 1973 the program was expanded to four traps, which caught 3,300 cowbirds and resulted in no parasitism that year. Like the prairie warbler, Kirtland’s Warbler displays a characteristic tail-bobbing behaviour; unlike the prairie warbler, Kirtland’s Warbler does not have a yellowish face. The festival is held annually during the first full weekend of June. American redstart. It has black lores (cheeks) and a distinctive, large and conspicuous broken white eye ring,[12][13] which it only shares with Setophaga coronata. Kirtland's Warbler was one of the first species to be listed under the Endangered Species Act after the ESA's passage in 1973. One of the largest and rarest warblers. The once nearly extinct Kirtland's warbler is creating a stir in the conservation world. [26], One study found that 85% of the singing males are able to attract mates. These managed units total 220,000 acres (89,000 ha). [34][35] Survival of this species will require management that will need to continue in perpetuity. The population of the species spends the spring and summer in their breeding range in Ontario, Wisconsin or Michigan, especially the northeastern Lower Peninsula of Michigan, and winters in The Bahamas and the Turks and Caicos Islands. Mayfield (1992, 1996) first stated that the bird inhabits the shrub layer. [2][21] The following year Edward Arnold travelled to a nearby locality in June and found the third nest ever, this one with four eggs. [10], By 1865 only four individuals of this bird were known; Baird lists the male specimen from the Bahamas which he had found in Cabot collection, the holotype specimen from near Cleveland, a first female specimen shot in 1860 near Cleveland and preserved by one R. K. Winslow as reported in The Ohio Farmer, and a fourth exemplar which Winslow mentioned had also been killed near Cleveland but had not been preserved. [35], There is a Kirtland's warbler festival in Roscommon, Michigan, which is sponsored in part by Kirtland Community College (which is named in honour of the bird). Kirtland’s Warbler is a medium-sized songbird. The Kirtland’s warbler officially came off the federal government's list of protected species Friday, officials said.
