John (760) has 14 species on Olaf (759):-
Buller's Shearwater - Code 2
Smew - Code 3
Hawaiian Petrel - Code 3
White-tailed Tropicbird - Code 3
Common Sandpiper - Code 3
Long-toed Stint - Code 3

Brambling - Code 3
Blue-footed Booby - Code 4
Yellow-legged Gull - Code 4
Kelp Gull - Code 4
Pin-tailed Snipe - Code 5
Cuban Vireo - Code 5
Olaf could do with either some short staying cripplers or some of those Code 3 Alaskan grip backs. John's Code 1 and Code 2 species will not elude him all year. Odd that John's gen has disappeared into a black hole again.
