Birder's Bonus 34

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.
