24 August 2011.
In the USA, NestWatch is a bird nest-monitoring project developed by the Cornell Lab of Ornithology in collaboration with the Smithsonian Migratory Bird Center, and funded by the National Science Foundation.
This video is called Brief, step by step overview of the NestWatch Instructions.
According to the NestWatch newsletter, the top 10 of nesting bird species this year as of 15 August is:
2. Tree swallow
3. House wren
6. House sparrow [see also here]
10. Purple martin
Back in 1890 a few well-intentioned bird-lovers decided to release a hundred European Starlings in New York’s Central Park. The birds adapted easily to their surroundings and soon spread to cities across the Northeast. As a consequence, though, many native Eastern Bluebirds lost their homes: here.
September 2011: The importance of gardens for the declining house sparrow has been underlined by new research. By looking at the location of house sparrow colonies in towns and cities across Britain, BTO researchers have discovered that houses with gardens are preferred over other forms of urban green space. This knowledge can be used to help urban planners in the decision-making process and gives hope that house sparrow decline can be reversed: here.
July 2012. With its cheeky nature and chirpy, chattering song, the starling is one of our most recognisable birds, but figures show that 40 million starlings have disappeared from the European Union, including the UK, since 1980. This crash is triggering concern about the bird’s future status as a widespread and familiar bird: here.
