Here is the Gud entry which you can find in the online edition of the Dictionary of Newfoundland English.
gud n Northern razor-bill (Alca torda); TINKER. 1884 STEARNS 235-6 I have often seen the water covered with a clustered flock [of puffins], all engaged in making a hoarse, rasping sound, not unlike the filing of a saw; this is also done both by the 'murre,' and the 'turre,' and at such times, which ever species is present, they receive from the sailors the name of 'guds,' from a fancied resemblance to that sound.
So that's what people have been saying all this time about Rattling Books!
"Some gud logo you got there b'y."
