I know this is a terrible shot but this bird has been around for some time and has totally evaded photos until now. You can at least see the pale silvery collar and the contrast between the black crown and grey face and nape. There are other subtle differences between this bird and our regular spermologus birds. I hope to get better shots but visits to the garden are brief and I only catch it every other week or so.
