Lord Condar

Lord Condar is a level 17 rare white condor (carrion bird) that can be found in south eastern Loch Modan south of Ironbrand's Excavation Site. He has a pretty large patrol are and he flies around rather quickly, I have indicated where he patrols in red on the map below. 

He drops the typical green item and a fairly decent amount of experience for leveling characters.

He is also desirable as a hunter pet for low level hunters as he is the only tamable white condor under level 70. The only other condors that share the same model and color as Lord Condar are level 70-71 Carrion Condors and the elite level 74 Dreadtalon in Dragonblight. 

Lord Condar is one of 5 rare tamable hunter pets in this zone. All of them are:

Ashtail, level 16 bluish-grey fox

Gosh-Haldir, level 15 green crocolisk

Lord Condar, level 17 white condor

Nix, level 17 yellow firefly

Shanda the Spinner, level 18 grey tarantula

Lord Condar can be found with NPCScan. You will need to add it, his NPCScan ID is 14268.

You can also use this macro to help find and tame him:
/tar Lord Condar
/stopmacro [noexists]
/cast Tame Beast

I'm not sure on his exact spawn timer, but before Cataclysm it was between 4-6 hours. I believe it is shorter than that now. It is also said that he may share a spawn with the eagles in the area and can be forced to spawn by killing them until he shows up.
