"At around 9:00 a.m. yesterday, we saw over 400 black-headed gulls flied on open waters of Dianchi Lake, including quite a few of young birds," Wang Yanping, an observer from Kunming Birds Association, said, "They might be spearhead group of the black-headed gulls. Citizens may see more black-headed gulls flying at Haigeng dam near to the Dianchi lake in a week."
Yang Ming, deputy secretary general of Kunming Birds Association, said: "To judge whether a group of black-headed gulls is a spearhead or not is to see whether young birds live in the group. By observing some characteristics of the gulls, we could judge that the group of black-headed gulls seen in the morning yesterday is a spearhead of mass black-headed gulls which may arrive in Kunming soon."
Yang pointed out a fact that feathers of these black-headed gulls on the Dianchi lake look bright and white also proves they had newly arrived at the place.
According to recent five years' data, the earliest time the black-headed gulls came to Kunming was on October 13, 2011, and the latest time the black-headed gulls came to Kunming was on October 22, 2012. And arrival time of the black-headed gulls to Kunming this year is 6 days earlier than that of the gulls last year, on October 21.
Yang said except for the black-headed gulls, more than 130 species of migratory birds also come to Kunming for spending winter every year.
