Strange goings on with respect to Jackdaw (Corvus monedula) populations. Large flocks of around 300-400 birds seem to be roosting by the Loughor estuary at Bynea. The birds return each morning to locations around Loughor and Gorseinon to forage. Their allelomimetic wheeling flight is not quite as impressive as that seen in Starling flocks but their current numbers (perhaps maintained over winter by feeding on human waste) seem potentially problematic for many smaller birds whose eggs and chicks can be decimated by these intelligent and voracious members of the crow family.
This blog may help people explore some of the 'hidden' issues involved in certain media treatments of environmental and scientific issues. Using personal digital images, it's also intended to emphasise seasonal (and other) changes in natural history of the Swansea (South Wales) area. The material should help participants in field-based modules and people generally interested in the natural world. The views are wholly those of the author.
