Transferred.
The only unconverted Greyhawk critter I see on Echohawk's list is "Raven (Crow) Huge". I'm not sure it needs converting, as we already have a giant raven in one of the FR books. I suppose we could make a "Dire Raven". I don't believe I've seen one yet.
There's a Large-sized Giant Raven in
Frostburn.
The AD&D "Huge Raven" is a man-sized intermediary between the (Large-size) Giant Raven and a regular Small-sized raven.
It'd be easy enough to stat up as a "Dire Raven". Just take an Executioner's Raven and transmute it from Extraplanar Magical Beast to Animal, then remove its Aligned Sight and darkvision:

A raven as big as a small human.
Dire ravens have the same habits and diet as normal-sized carrion crows and ravens. Like their smaller cousins, these scavenger birds are remarkably intelligent animals. A young dire raven can be tamed and taught tricks. In the wild, dire ravens sometimes learn cunning stratagems to find food or deceive predators.
Dire ravens show little fear of humanoids. They normally only fight if they feel their lives or nests are endangered. However, a hungry enough flock might try to kill and eat man-sized creatures.
Dire ravens are about 5 feet long and have wingspans of about 10 feet.
COMBAT
Dire ravens tend to strike at their opponents' eyes, attempting to blind them. They usually fly away as soon as a battle turns against them.
Eye Gouge (Ex): If a dire raven scores a critical hit with its bite attack, the target must succeed on a DC 15 Reflex save or lose the sight in one eye, becoming permanently dazzled (or blinded if they lose the use of all its eyes). A
remove blindness/deafness spell can heal the injury. The save DC is Dexterity-based.
Resistant to Disease (Ex): A dire raven has a cast-iron stomach. It has a +2 bonus on Fortitude saves to resist normal diseases, but not supernatural or magical diseases such as mummy rot.
Skills: A dire raven has a +4 racial bonus on Spot checks.
