Bird watchers recorded two species that were new to the annual Christmas Bird Count last week.The enthusiasts fanned across Bermuda for the count which was held on December 27. In total 7,659 birds were seen, down by more than 1,000 compared to last year, with the European starling accounting for just over a quarter.The Bermuda Audubon Society, which organised the count in conjunction with National Audubon in the US, reported that a total of 88 species were counted - reversing an upward trend over the last few years. The count recorded 101 species in 2010, 100 in 2009 and 97 in 2008.Spittal Pond was the site of the “bird of the day”, a MacGillivray’s warbler which has only been recorded in Bermuda once before. And a garganey - a duck from Europe - was recorded for the first time.Two Iceland gulls, and three yellow-billed cuckoos were also spotted.“It is extremely rare to find cuckoos wintering in Bermuda but these birds had obviously remained following a large fall of these birds in October,” a press release issued by the Audubon Society said.More than half of the birds recorded were starlings, kiskadee or sparrows - all invasive species which are having a negative impact on local birds.And habitat loss and the effects of global warming have taken their toll on the warbler population, as just 18 warbler species were recorded this year, as was the lowest ever number of American redstarts.
