- W2317746593 abstract "IN 1951, one hundred years after the discovery of the Kirtland's Warbler, Dendroica kirtlandii, 32 people participated with me in a count of singing males of the species throughout its nesting range (Mayfield, 1953). This was perhaps the first attempt of any group to census an entire species of songbird. In 1961 we repeated the count in exactly the same way, with 48 participants. The number of male Kirtland's Warblers in 1961 was 502, as compared with 432 in 1951. This is a 16 per cent increase but leaves the total population of adult warblers still in the vicinity of 1,000 birds of both sexes -a perilously low number for a species of small migratory birds." @default.
