Rather see a Rainbow Lorikeet! Or a Cardinal. Or a Gold Finch. Or a Flamingo. Or a Eastern Bluebird. Or a... you know... not that this bird isn't the sweetest bird that ever walked the earth or flew in the air, but... COLOR! I need COLOR!!!!
(Does that mean I'm being shallow today?)

Shiela, don't worry. It's Monday. It'll wear off.

Maybe if it was shot in Black & White Shiela would like it better.

It's not pigeon-toed!

I would like to see a few coloured birds too. Our usual flocks seem to have left for the warmer areas. Can't blame them really. My toes are cold & I'm thinking longingly of summer already!!!

Forget the pigeon, I did this as a sudoku and learned that "All moves correct so far." does not apply to possibilities!

1) Start 23, basic techniques to UP=30
(note np: ab3=68,gi2=68,b37=68,dh3=34)

2)Coloring (6):ac8=b7-b3=a3,=>a46<>6. UP=31

3)fc:(2)g8=(2)h8-(2)h6=(2-8)e6=(8)e8,=>g8<>8.UP=81

Maen Sotir,
Your second step starts with (6):ac8=b7 but 8 is still a possibility in c9 so this is not a valid strong link.

A short path:
A short path:
1) Start 23, basic techniques to UP=30
(note pairs: ab3=68,gi2=68,b37=68,dh3=34,ae9=17)

2)(6)c6=(6)c8-(6=8)b7-(8=5)c9-(5=2)c1 => c6<>2

3)(8)e8=(8-2)e6=(2)h6-(2)h8=(2)g8 => g8<>8.UP=81

Hi Jeff,

There is a misunderstanding.The second step
is for 6s,not for 8s.
Your second step also is excellent.
Best regards.

Wow, I completely misread that step even though it clearly says 6 twice! Keep up the great work!

I really appreciate the proofs that everyone posts, for many of the toughs they are the only way that I get the solution. I refuse to guess but I only have limited amounts of time to spend here.

These guys are speaking an unusual language. For somebody with dyslexia like me.... DUH.

I really like pigeons and this one is a very unusual color.
