Eeek! So many responses! Thanks for all the help!
I would also say white, not only because I love black/white IRL, but also that s/he fits your hunter nicely, as someone else said, your hunter has toned down colours, and so does the white birdie.
Too bad that you can't really see yourself using the ghostly though, because that is a nice bird! But on the other hand: what's the use of having pets you never take out, right?
Truth! Especially when stable space is... Limited. Twenty five slots aren't enough sometimes! The ghostly's an amazing skin but tricky to integrate into RP activities, gah!
Try also to check out the green two-headed vultures in blasted lands (they fly around high above the ground so try landing on mountainsides to get them down) and well, just to check it out, spiteflayer if your into yellow xD Red ones carry a very royal 16th century look with them and their white ruffles and I named one Kenneth which means 'born of fire' cause i tamed Emberwing
Not sure how big you are on bald one headed vultures but this guy wouly look awesome against your RP armor seeing as its blue, the white im throwing in just cause, seeing as you said you have Zariotl
Delicious name, there! Do have Spiteflayer on a goblin hunter, though haven't tried the red or the green. Must... Resist! Love these birds far too much. They're surprisingly elegant! If a little freaky.
And adore the bald vultures! Used to have both of them, but the flying animation bug makes me tear my hair out! Have kept the blue around, but haven't let him out of the stables in ages.

Waiting and praying for a fix, he's one of my favourite skins!
Leaning towards the white-- hair-matching is persuasive-- but the blue one's good too. The ghostly one though... nope. Nope nope nope. Something about the combination of "corporeal carrion bird" and "smoky glowing carrion bird" just doesn't do it for my sense of taste. And a troll! Trolls aren't silly enough to be running around with sparklebirds. That's for the elves.

Can't help but agree with you, even if my troll's silly enough to run around with a sparklebear! ... Away from RP hubs, of course.
Going along with this, I actually don't think trolls like birds at all (hence troll druid having a bat flight form) so I'm not sure a troll RPing with true, trollish pets would even have birds as pets. Someone feel free to correct me if I'm wrong.
And if you're not trying to RP with trollish pets, it doesn't even matter.
Darkspear trolls do
hate birds! It varies between troll types though; forest trolls such as the Amani trolls follow a bird Loa, I believe. Pretty sure the Amani wouldn't dare raise a Darkspear either- they'd likely sacrifice and/or eat anyone that's not part of their tribe! Elves especially!
Tend to stick to reptilian creatures for Vasken, but the occasional bird (AND A FLOOF) somehow manages to slide into his stables. Have only ever (briefly) used one bird in-character, but the idea of having a "
WhyisthisfollowingOHLOAIHATEITSTOPFOLLOWINGME. LETGOOFMYEARGJDjfhhdhsj-" pet that constantly embarrasses the troll by its presence was a bit too endearing.
/walloframble. T'anks a millian fo' all di suggestians tho'! It bie lookink like Ah'll have ti pick 'dat white flufeh-t'ing 'ap! SAH much easiah 'dan starink fo' HOUAHS at di stables an' pinink ovah each an' evereh birdeh. Moah slots pleez!
Hopefully haven't missed anothing.
