White-headed Duck at Slimbrdge WWT

I looked out on dismal day, I'm not going out to take some photos-maybe it be better that this morning, but, I was wrong. If you look at the weather report, it doesn't look very nice, in fact, it hasn't been very nice since the begin of December. But, I'm not too bad, compared to others that have the worst of it. It is A CLIMATE CHANGE.

  10. Range and population Oxyura leucocephala is resident in Spain, Algeria and Tunisia. A larger population breeds primarily in Russia and Kazakhstan, and also Turkey, Iran, Afghanistan, Tajikistan (likely small and declining), Turkmenistan, Uzbekistan, Armenia, and Mongolia (believed to be increasing in this latter). Its status in China is unclear, but it appears to be rare. It occurs on passage/in winter in the eastern Mediterranean, the Middle East, and central and south Asia. The population was probably over 100,000 in the early 20th century, falling to an estimated 19,000 birds in 1991, since when numbers have probably declined to less than 10,000 individuals. Concurrently, breeding populations have become extinct in Italy, France, Hungary, Albania, Yugoslavia, Greece, Israel and Egypt, and probably also in the Ukraine and Armenia. Exact population trends are difficult to calculate given that numbers on wintering grounds often change dramatically in line with altered water availability. At the former key wintering site, Burdur Gölü, Turkey, numbers have steadily declined from 10,927 birds in 1991 to 653 in 200116. The total Turkish wintering population in 2005 was only 1,006 birds, down from over 9,000 in 198812. The wintering population in south Asia is mainly concentrated in Pakistan, where it has declined from 1,039 individuals in 1968 to less than 10 in 200210,in January 2003 and 24 in January 2004. It is now only rarely recorded in India. Increases at wintering sites in Israel11, Syria, Greece5, Bulgaria and Romania and in the Spanish population (22 birds in 1977 to 2,396 birds in 20002) do not compensate for the large declines at Burdur Gölü; and in other eastern populations (e.g.,Turkmenistan). Important passage concentrations occur in Uzbekistan8 and Kazakhstan. There are also reports of wintering populations in the Ukraine.
