Laurie took some great footage (given the dull, dark and cloudy conditions) of the crossbills we saw yesterday in Coed Maenarthur. One of the pics shows a crossbill with a large piece of pine bark in its beak. A male was seen to present a piece of bark to a female and one was seen in courtship flight making its trilling call so its likely considering the huge seed crop this year that they are about to nest.
