Missed the RFF again!

I have missed a lot of birds this spring and the Carlton Marshes RFF is no exception, despite being there, 9.30- 2.15pm, this was the first time the RFF wasn't seen during the 10-2pm period seen it first arrived. Around 20+ Hobbies flew over Peto's catching dragonflies and other insects. as I walked up to the Moorings hide, a Greenshank flew west over the river, calling as it went and appearing to settle on the western end of Peto's. A Painted Lady was also feeding on the clump of yellow flowers by the path. Bitterns were also seen in flight twice, one landing in reeds fairly close to us. 5 marsh harriers and 5 Buzzards seen too. Matthew D. joined us and when we left we saw first a male and the another Wall Brown in flight. The male was seen perched several times. Walking back 5 Sand Martins flew over the track.
