If you like observing the type of wildlife that doesn't involve alcohol consumed in dark bars, there's another reason to head for Europe in the cooler months--mating season (not for pink elephants or humans--that would be wrong--but for pink flamingos).
The best time to see flamingos according to experts is during their reproduction process. Oui, mating season! When is that? In the Camargue, it is recommended to see the flamingos during the winter months, any time between November and March. However, THE most ideal time to visit is actually in January and February according to the Parc Ornithologigue, (where we saw the flamingos) just 4 kilometers from the center of Saintes Maries. 10,000 flamingo couples gather around to do their thing.
The above quoted passage is part of a very interesting and comprehensive blog post called The Best Time to See Pink Flamingos in the Camargue, recommended reading on this fascinating part of the south of France.
It was rather spectacular to watch the flamingos in early November though. Here's a link to a short Camargue Pink Flamingo Video I made while we were there.
