Wild Duckling

Above the Valdrakken bank is a little pond where pets often spawn.  If none are there, kill the critters and they should respawn as pet battles soon enough.  The Wild Duckling which spawns here is a blue quality battler very often.  (I have only seen H/B type blues here).  It's often enough that I check whenever i am in the area and have gotten most of my guildmates to pop over and battle it for their blue quality pet as well.  

I found him primary two times at Uktulut Outpost, The Walking Shores, at 16.80 89.75

Both times i tried to catch him I accidenatly killed him, he is weak and a bit tricky to get in the 30% window to throw the trap.

I just killed him a 3rd time at Ruby Life Pools, (57.0, 71.1) but I can confirm he seams to spawn fast, and on 4th try I got him in the windows so I could throw the trap and catch him.

Plucky Duckling also spawns here 

Found as primary at Ruby Life Pools (56,71). My first was a common quality, then waited for another to spawn (about 2 minutes), next was uncommon, then third was rare. GL hunting!

Found as a primary: Waking Shores 78.1 51.2

Found as primary near Ruby Life Pools (56, 70) in The Waking Shores.
