Spring 2016 campaign on Lilford's lizard ended!

The 2016 spring campaign on Lilford's lizard ended last week. It has been a difficult one, with many days of bad weather and several unexpected problems with boat and logisitc....but hey, this is job. Populations reached a very low level, but it seems there will be many new recruits in October. Thank to the many people from the GEP who gave their help.

First long tracks from Dragonera

The GSM/GPS devices are sending interesting information on bird movements. Marked gulls seem to have moved their core area northward, between the delta of the river Llobregat and the landfill, north of Barcelona city.

Thanks to T. Muñoz, of the G.O.B., who helped us to equip four birds with a GSM/GPS device to investigate their feeding strategy.

Gulls use to attack intruders, especially near the hatching period. It is a good occasion to make some pictures and read the ring. 

Can you read the ring code?
