During our visit to the Tall ships festival, Keith and I took the opportunity to drop into the Greenwich Ecology Park to see if any Common Terns had arrived after migration at this breeding site and also to check whether the first dragonflies had emerged. The reserve was relatively quiet with just a few resident birds present – there were no Terns to be seen and no dragonflies either.
On leaving the reserve we walked towards the O2 dome and we found two Common Terns sitting on a barge in the middle of the river, along with a selection of Gulls.

No mention of the Sand Martins?
Did the list from memory a couple of days afterwards as I didn’t write it down at the time. Had completely forgotten that we saw 2 Sand martins. Will amend my list. Thanks you
