I was going around Hackney Marshes on Thursday (14th), botanising and birdwatching. At 1240 I reached the area where I think the Little Owl is supposed to be in, by the Flood Relief Channel culvert discharge in to the Lea. There I came a cross a family of 8 rapidly growing Mallard chicks. Then on the lip of the culvert I saw a drake Mandarin, my first in this area. It wasn’t looking lost, but started to busily see off 2 drake Mallards also on the lip, which were chasing a female. They then all flew off to the West.
