Yellow legged GBB Gulls (1 Viewer)

Dean Nicholson

Cloacal Protuberant.
Two adult marinus in Penzance, Cornwall last week with yellow legs and feet, presumably a pair (one obviously heavier than the other) as both birds stuck together over the two days they were present - the smaller female type with less black on the upper mandible had the brighter legs, even brighter yellow in the flesh than depicted in the pics, I've seen the odd GBB in the past with faint yellow hues to the legs but never to this extent - all other GBB's present had typically fleshy/grey legs....so presumably diet related? but if that's the case then what have they been eating that the others haven't??

Unfortunately both had lots of white on p9 and p10...:-C
