I even pondered going to Zoo Veldhoven just for the purpose of this challenge but as I was limited in time, it was either go to Veldhoven (just for parrots) or go to Burgers' Zoo. Let's say the choice was an easy one (even if Burgers' didn't get me any parrot addition).
This should be my only large batch for the year but if plans go through, I should be back in Europe pretty soon and I'll probably have a few zoo visits then.
