Hi!
I went to my beloved ZOO Olomouc to photograph animals yesterday - I needed a break from the thesis writing.
I spent hour or maybe more with my favourite wolf subspecies - Iberian wolves. They were very active and even aggresive, snapping their jaws and snarrling a lot. One of them tried to catch a crazy rodent. It was fun and I got many photos for you

But the bad news - fennec fox got a new light in their enclosure. It is a red light and it TOTALLY does not allow you to photograph, because the specific light ruins the texture of the animal's fur and there is no chance to get any photo

I am sad about it, I loved this place for fennec photography

now it has been lost... in ZOO Dvur Kralove, they put those foxes into very dark indoor exhibit, so this place is also lost and in Prague, you never see them... Hm... I am a bit sad about it, I would miss those little guys

I also definitely need a new lens. My current one had troubles to focuse yesterday and I could not take a sharp picture for several minutes... I am more and more sure I should buy Canon 70-200 L 4 USM (not IS version)... it is relatively achievable and people say the quality is great. But I am still nervous about the lack of IS :/
Ok, wolves and kiriban. Then thesis again. Sigh.
Like most desert-dwellers, Fennecs are nocturnal; the new red light would be easier on their eyes, and they'll most likely be more active with it! Most of the zoos I've been to have the nocturnal animals in a specific building where they can keep the lighting low and use those red lights. I know it does make it hard on photographers, but it really is better for the animals; as a warning, if they are doing that with the Fennec Foxes, the Sand Cats (if they have them) may be next. *is Zoology major*
Maybe they were becoming stressed, or even were becoming sensitive to light. You could probably ask a keeper, and they could tell you.
Best of luck with the thesis! c:
Well, at least you were able to show us all of those beautiful ones you've already taken! I still LOVE
I don't suppose a filter would help get past the lighting issue? Odd they'd put a red light in there. Heating lamp maybe? I'd say they are some spoiled fennecs over there.
