Cranes in Britain

__NOTOC__Cranes are large, long-legged and long-necked birds of the order Gruiformes. Two species occur as wild birds in Britain: the Common Crane, a scarce migrant and very localised breeding resident, and the Sandhill Crane, an extreme vagrant from North America. A third species, the Demoiselle Crane, has been recorded on a number of occasions, but these birds have not generally been accepted as being of wild origin.

A number of other species are kept in captivity, resulting in the possibility of escapees being seen.

Common Crane

Historical occurrence

The Common Crane is generally believed to have been a breeding bird in Britain in the Middle Ages. Confusion arises as the Grey Heron was, and still is, known as "crane" in many parts of rural England. Among the strongest evidence that Common Cranes did genuinely occur was the fact that an Act of Parliament of 1533 included a measure that made the taking of cranes' eggs an offence, punishable by a fine, and five mentions in the "Household book of the L'Estrange family" of the supply of cranes for their larder between 1519 and 1533.

Migrant status

Common Crane is a scarce spring and autumn migrant to Britain, with occasional birds remaining in winter or summer.

Recolonisation of the Norfolk Broads

In the late 20th Century, Common Crane recolonised the Norfolk Broads; the species has now established a resident population of some 20 individuals. This population is centred around the northeastern part of the Broads, in the Sea Palling / Horsey / Hickling area.

The origins of this population can be traced to 15 September 1979, when two birds appeared near Hickling Broad; these two were joined by a third bird on 10 October. On 7 October, a Crane with a rubber object wrapped around its bill was found in the Irstead / Horning area. It was taken into care and released on Horsey in March 1980, temporarily bringing the population to four.

The 1980s

By the end of April 1980, only two birds remained; however, these birds stayed throughout 1980 and 1981, and in 1982 raised a single young, the first successful breeding in Britain for around four hundred years. A second young was raised in 1983, but disappeared before the end of the year. An additional bird joined the group on 16 August 1982, and remained with them until at least 1987.

Further breeding attempts were made from 1985 through until the end of the 1980s, those in 1986 and 1988 being successful, with one young each raised. In addition, further migrant birds joined the flock; not all stayed, however both the wintering and summering populations steadily grew, as shown below:

Recent summering birds elsewhere in Britain

Away from the Broadland population, other birds have shown breeding behaviour, including:
* a displaying pair in Essex from May to September 1987
* pairs at two localities in Yorkshire in 2002, one of which was observed displaying
* a pair which nested in 2007 at Lakenheath Fen in Suffolk [ [http://www.rspb.org.uk/news/details.asp?id=tcm:9-159692 RSPB article] (accessed on 18 May 2007)] [ [http://new.edp24.co.uk/content/news/story.aspx?brand=EDPOnline&category=News&tBrand=edponline&tCategory=news&itemid=NOED16%20May%202007%2021%3A12%3A40%3A023 Eastern Daily Press article] (accessed on 18 May 2007)] . A second pair was also present, but did not breed.

andhill Crane

Sandhill Crane is a very rare vagrant in Britain, having been recorded just twice, both times on Shetland:

* a first-summer on Fair Isle on 26 & 27 April 1980
* a first-summer bird at Exnaboe from 17 to 27 September 1991 (this bird was subsequently seen in the Netherlands)

Elsewhere in Europe, there are records of Sandhill Crane from Galley Head, County Cork, Ireland in September 1905, and from the Faroe Islands on 14 October 1980.

Demoiselle Crane

Demoiselle Crane has been recorded a number of times — in Cumbria, Dorset, Hampshire, Kent, Lanarkshire, Lancashire, Lothian, Norfolk, Orkney, the Western Isles and Yorkshire. The origin of these birds is not known, and they have not been accepted onto the British List.
