The best fieldwork site!

It was such a stunning spring day yesterday that there was only one place to be... out on the water! So we fitted in another visit to the Kittiwakes at Trewavas Head, this time managing to land by the engine houses. This part of the colony was worryingly quiet though, with fewer than 50 birds on the ledges, instead of the usual 65+ pairs! Just three of our colour-ringed birds were present, but hopefully this is just a slow start to the season here.

The main face at Trewavas Head was slightly busier which was encouraging. Here we were able to record a further dozen of our own birds, including two that have previously been seen on their wanderings - see here and here.

It was also great to see two of our birds as a pair now,
giving us much better information on the workings of the colony

In amongst our own colour-birds were three French-ringed birds. Two of these are known to us already, but typically the one new bird to us was so high up on the face we could only see two colours and part of the metal ring, so it remains unknown (for now!).

ONN-YOM was ringed as a chick at Pointe du Raz in 2002
and has been regular at Trewavas since we first visited in 2012
OWM-RNN was ringed as a chick at Pointe du Raz in 2007
and has been seen six out of the last seven years at Trewavas
