As regular CFZ-watchers will know, for some time Corinna has been doing a column for Animals & Men and a regular segment on On The Track... particularly about out-of-place birds and rare vagrants. There seem to be more and more bird stories from all over the world hitting the news these days so, to make room for them all - and to give them all equal and worthy coverage - she has set up this new blog to cover all things feathery and Fortean.

Britain needs more nestboxes

As part of National Nest Box Week 2019, which kicks off on Thursday 14 February, the British Trust for Ornithology (BTO) is calling for homeowners to put up more nestboxes for declining garden birds.
The simple act of putting up a nestbox can make a real difference for our birds, providing them with the space they need to raise a family. A growing proportion of the global human population now lives in towns and cities, with the United Nations predicting that two-thirds of humans will live within such urbanised landscapes by 2050. Urbanisation is considered to be one of the greatest threats facing bird populations, resulting in the loss of natural habitats and the feeding and nesting opportunities associated with them. 
Newly urbanised landscapes often lack the mature trees that provide nesting cavities for small birds, such as Blue Titand Great Tit, while other cavity-nesting species – such as Common StarlingCommon Swift and House Sparrow – have seen changes in building regulations reducing nesting opportunities that once existed under the roof tiles of our houses. The loss of such sites may have played an important role in the significant declines seen in the breeding populations of these species since the early 1990s (Starling by 74 per cent, House Sparrow by 35 per cent and Common Swift by 51 per cent).
