This afternoon, as I worked in the Deep Pit with my volunteer, a Black Swan flew over the site, with three Mute Swans, giving a pathetic squeak as it passed. Later two adult and two juvenile Mute Swans landed on the ice on the Slurry Lagoon, skidding as they landed accompanied by hilarious screaming from a Water Rail. As we were preparing to go, an immature Glaucous Gull flew over the site, possibly from the Large Gravel Pit, and headed towards Holme Pierrepont. PS. DM.

Earlier in the day two Tree Sparrows were seen in S.T. hedge line near to the Mitigation Field. JMD.
