Up to two yellow-browed warblers remained in the copse to the south side of the reserve centre all day. Some of us were lucky and got pretty good views but for others the birds were frustratingly illusive. A bird was still calling as I left around 5pm. A group of crossbills flew over in the gloom at 8.30am and two wheatears followed me round while I was working in the tractor west of the pool.
