Dunnock

More camouflaged in large ("L").

This is a dunnock or hedge sparrow (Prunella modularis). All the others species in the genus are called accentors (Alpine accentors or Japanese accentors, say), and dunnocks are sometimes called hedge accentors, but we seem mostly to call our British accentors "dunnocks".

I went to Wandsworth Common and found this dunnock in the same place as last week's juvenile robin. I went to check on the Egyptian goose family (previously uploaded to Flickr here) as Ann had been told that the smallest fledgling had disappeared. She also told me that the old cob swan had been killed by a dog, which is tragic. One of the fledglings is indeed missing, but it isn't the smallest one, which is still around and still supercute. The other fledglings are quite big, so it is possible that the missing one has just moved on (rather than having met the same end as the swan). The smallest fledgling is developmentally abnormal: each year this set of Egyptian geese seem to have a runty gosling. This one isn't as delayed as last year's one, but is much smaller and younger-looking than its siblings, and has a small facial defect (a strange patch of feathers to the left of its beak). I was tempted to blip it, but have included it in a set of shots on Flickr as it is a perky little thing and rather pretty.
