HEMEL MEGA: MARSH HARRIER around Boxmoor still!

I received a message from Mark saying that he had seen a MARSH HARRIER sat on the gas tower frames near London Road, between the Bulbourne meadows & Roughdown Common at Boxmoor until 8.15 at least - so the bird from yesterday roosted here overnight & could stick around for a bit if the strong winds persist so keep an eye out & double check those Buzzards.
