Since 7 October 2023 an average of 27 children have been killed in Gaza by Israel every single day. A whole classroom of children wiped out everyday by a genocidal regime, even while queuing for food and water. And still the UK government sells them weapons. Shame on them.

Nice story from one of our campus mallards. I ringed JI last Sept and she began nesting in a plant pot on campus in early May. The clutch hatched at the end of May but there was no sign of her brood - until yesterday when I saw JI on the Colne (1km from campus) with 3 ducklings
JI with her new set of rings in September JI on her nestThe remains of JI’s nest after hatching - some eggs successfully hatched while others appeared to have been predated JI feeding in the mud with her brood

DUCKS: by this time of spring most ducks will have settled at potential breeding sites. So all records of scarce & rare breeding ducks, including Shoveler, Wigeon, Garganey, Pintail, Pochard and Red-breasted Merganser, should be submitted, with breeding evidence, to the relevant county recorder
A female Shoveler, the focus of attention for five drakes at a wetland in Northumberland this week. She appeared to be paired with one, so that’s a ‘probable breeding’ record.
