Yellow Legged Gull campaign on the starting blocks

The Yellow Legged Gull 2017 campaign at Dragonera Naural Park is on the starting blocks. We have received two nice pics from C. Loske of a newly marked gull (top) and an old one (bottom), respectively. Thank you Carl !

The 2016 Yellow Legged Gull campaign has just started at Dragonera island. 
Birds are building their nests while few are already incubating. A good moment to read rings.
